Project Axiom：用 C++23 与 CUDA 从零构建的多模态 AI 引擎

The Silicon-Native, Zero-Overhead Multimodal AI Engine

Engineered from Scratch in Modern C++23 & Bare-Metal NVIDIA CUDA

Project Axiom is not a Python wrapper. It is not an abstraction layer. It is a hardcore, bare-metal rewrite of deep learning mechanics engineered directly in C++23 and NVIDIA CUDA. By stripping away garbage collectors, runtime interpreters, and framework bloat, Axiom achieves absolute mastery over modern silicon: 100% Tensor Core saturation, zero-latency PCIe DMA streaming, sub-millisecond prefill latency, and seamless continuous learning.

🎯 The Philosophy & Mission

The Industry's Flawed Premise

Modern Artificial Intelligence is drowning in software bloat. Enterprise workflows rely on colossal, heavily abstracted Python frameworks (PyTorch, TensorFlow, JAX) that introduce massive architectural penalties:

1. Garbage Collection Pauses: Python runtimes trigger non-deterministic memory reclamation, inducing micro-stutters during high-throughput training and inference.
2. Interpreter & Driver Overhead: CPU thread orchestration takes longer to submit work through layered driver shims than the GPU spends executing tensor operations.
3. Severe VRAM Fragmentation: Continuous allocation and deallocation of dynamic activation tensors fragment GPU address spaces, leading to premature Out-Of-Memory (OOM) crashes.
4. Indiscriminate Data Ingestion: Traditional models scrape uncurated internet sludge, triggering synthetic feedback loops, bias amplification, and catastrophic model collapse.

The Axiom Paradigm

Project Axiom rejects this paradigm entirely.

• Bare-Metal Silicon Control: Axiom controls the exact byte layout of every buffer in physical host RAM and device VRAM.
• Hardware-Native Primitives: Computations are dispatched via custom .cu device kernels and NVIDIA CUTLASS v4.8 templates directly targeting Tensor Cores on Ada Lovelace (sm_89) hardware.
• Total Privacy & Local Execution: Axiom runs 100% offline and locally on consumer GPUs (e.g., RTX 4080 Laptop / Desktop), providing an autonomous sandbox to train, experiment with, inspect, save, or wipe custom neural weights in milliseconds.
• Curated Single-Model Philosophy: Axiom delivers a unified neural architecture designed to master handpicked, verified datasets. End-users run pre-trained checkpoints with zero friction (.\app.exe --use), while developers fork the engine to train continuously on custom knowledge bases.
• The Scientific Horizon (The Rewind Test): Axiom serves as an empirical research sandbox to test the boundaries of computational determinism. By feeding hardware thermal entropy (std::random_device) into Axiom's unified mathematical space, we test whether a neural network can reverse-engineer physical entropy generators and predict physical jitter.

🔥 Core Innovations

1. 🌌 True Native Multimodality (Discrete VQ-VAE Space)

Unlike traditional LLMs that treat text as primary and graft foreign modalities through cross-attention shims, Axiom maps all modalities into a single, unified mathematical space.

Using a discrete VQ-VAE inspired integer spacing mechanism, token identifiers are isolated into distinct, non-overlapping numerical domains:

Note

Because each modality occupies an orthogonal $10,000,000$-integer slot, modal namespaces never collide during embedding generation. Text, vision, audio, and numbers flow into the same context vector as a unified stream of reality.

2. ♾️ "The Seam": Continuous Sliding Window & Carry-Forward

Standard machine learning batch loaders chunk datasets into isolated blocks. When a buffer runs out of data, standard loaders discard it and load the next, causing Historical Amnesia at the boundaries and breaking sequential continuity.

Axiom introduces The Seam (Carry-Forward Mechanism):

[--- Book 1: 100,000 Tokens (RAM Buffer) ---------------------------------]
[ Window 0 ] -> [ Window 1 ] -> ... -> [ Window 99,872 (Last Window) ]
                                          |-- Context (128) --|- Target (1) -|
                                          [ Tokens 99,871..99,998 | Token 99,999 ]
                                          ========================================
                                          SURGICAL SLICE: Extract Last 128 Tokens
                                          ========================================
                                                             |
                                                             v
[--- Book 2: Next 100,000 Tokens (Prepend Slice + Disk Fill) -------------]
[ Carried 128 Tokens ] + [ Newly Streamed 99,872 Tokens from Disk ]
[ Window 0 of Book 2 ] -> Perfectly bridges the gap with ZERO Cold Starts!

The Analogy: The Library, The Book, and The Page

• The Library = NVMe Hard Drive: Massive storage, but too slow to access randomly per step.
• The Book = System RAM Buffer: One $100,000$-token chunk ($400,000$ bfloat16 elements) resting on the desk.
• The Page = Context Window: Exactly $128$ tokens ($512$ elements) fed to the Perceptron at a time.
• Ripping the Last Page Out = The Carry-Forward: When reaching the final page of Book 1, Axiom preserves the final $128$ tokens and staples them to the front of Book 2 before streaming from the NVMe. The AI's context stream is never severed.

3. ⚡ Zero-Latency Pinned Memory & PCIe DMA

Standard C++ heap allocations (std::vector, malloc) reside in pageable virtual memory. When transferring pageable memory to the GPU via cudaMemcpyAsync, the CUDA driver cannot perform Direct Memory Access (DMA) because the OS might swap the memory page to disk at any time. The driver silently degrades into a synchronous, blocking transfer through a hidden staging buffer, stalling the CPU.

Axiom eliminates this bottleneck:

• cudaHostAllocWriteCombined: Locks host memory physical pages into pinned RAM and applies write-combining cache flags.
• Bypassing CPU Caches: Write-combining bypasses the CPU's L1/L2 caches, writing directly across the PCIe bus interface. This accelerates PCIe bandwidth throughput by up to 40%.
• Direct DMA: The GPU's independent DMA copy engine directly accesses physical host RAM without interrupting CPU execution.

4. 🏓 Asynchronous Multi-Stream Ping-Pong Buffering

To ensure the GPU never waits for data, Axiom implements a double-buffered execution pipeline over two independent non-blocking streams (cudaStreamNonBlocking):

Timeline:
Stream 0: [=== DMA H2D (Buffer 0) ===][=== Tensor Core GEMM + Backprop ===][ Event 0 ]
Stream 1:                             [=== DMA H2D (Buffer 1) ===].........[=== Tensor Core GEMM + Backprop ===]
CPU Host: [ Prep Buffer 0 ]           [ Prep Buffer 1 ]                    [ Prep Buffer 0 ]

1. Step $N$ (Buffer 0): Stream 0 executes the forward and backward passes on the RTX 4080 Tensor Cores.
2. Concurrent Overlap: Simultaneously, Stream 1 executes asynchronous PCIe DMA to transfer Buffer 1 into device memory.
3. Event Serialization: Stream 0 records compute_done[0]. Stream 1 waits on compute_done[0] before starting its forward pass, guaranteeing that weight updates remain strictly serial while memory transfers remain 100% overlapped.
4. Result: Compute latency completely hides memory transfer latency. The GPU never idles.

5. 🚀 CUTLASS v4.8.0 Tensor Core Saturation

Basic CUDA kernels with nested loops dispatch to scalar CUDA cores, leaving over 95% of Ada Lovelace's computing power unutilized.

Axiom integrates NVIDIA CUTLASS v4.8.0:

• Operation Class: cutlass::arch::OpClassTensorOp targeting cutlass::arch::Sm80 / sm_89.
• Hardware Instruction: mma.sync.aligned.m16n8k16.row.col hardware matrix multiply-accumulate instructions.
• Precision: cutlass::bfloat16_t input operands with float (FP32) accumulation.
• Tiling Hierarchy:
  • Threadblock Tile: $64 \times 64 \times 32$
  • Warp Tile: $32 \times 32 \times 32$
  • Instruction Shape: $16 \times 8 \times 16$
  • Pipeline Stages: 4 shared-memory pipeline stages.

6. 🌲 Epilogue Visitor Trees (EVT): Zero VRAM Round-Trips

In standard frameworks, a layer computes matrix multiplication, writes the intermediate tensor to VRAM, launches a bias-addition kernel, writes back to VRAM, launches an activation kernel, and writes back to VRAM. These round-trips consume massive memory bandwidth.

Axiom solves this with CUTLASS Epilogue Visitor Trees (Sm80EVT):

                     VisitorAuxStore (Write final BF16 to VRAM)
                                        |
                 VisitorCompute<ReLu> (Fused Non-Linearity)
                                        |
                 VisitorCompute<plus> (Fused Vector Addition)
                                 /              \
         VisitorAccFetch (Accumulator)      VisitorRowBroadcast (Bias Vector)

The GEMM accumulator, bias addition, and ReLU activation are fused into a single kernel. Mathematical operations execute entirely inside GPU registers and shared memory before writing the final activations to VRAM once.

7. ⚖️ High-Precision Master Weights & Rank-1 Backpropagation

During gradient descent, multiplying gradients by small learning rates yields parameter updates smaller than bfloat16's 7-bit mantissa, causing gradient underflow and stalled learning.

Axiom implements a dual-precision architecture:

• FP32 Master Weights: The optimizer maintains high-precision FP32 copies (d_weights_master, d_bias_master).
• Kernel Execution: The custom backward_pass_kernel computes exact MSE loss gradients, evaluates the ReLU subgradient, updates the FP32 master weights via SGD, and atomically accumulates the step loss.
• Rounding: Updated FP32 weights are rounded down to __nv_bfloat16 in-place on the device for consumption by the next step's CUTLASS Tensor Core GEMM.

8. 💾 Single Model Binary Weight Persistence (weights.axiom)

To guarantee permanent neural parameter retention with zero external serialization dependencies (Protocol Buffers, FlatBuffers, or Python pickle), Axiom implements a compiler-safe direct binary weight format:

[AxiomWeightHeader: 40 Bytes]
  ├── magic[8]        : "AXIOM_V1"
  ├── in_dim          : 512  (Context Window Float Count: 128 tokens * 4 dim)
  ├── out_dim         : 4    (Target Token Float Count: 1 token * 4 dim)
  ├── weight_count    : 2048 (512 * 4 FP32 Master Weights)
  └── bias_count      : 4    (4 FP32 Master Biases)
[Weight Payload: 8,192 Bytes] -> 2048 * sizeof(float)
[Bias Payload  : 16 Bytes]    -> 4 * sizeof(float)
Total File Size: Exactly 8,248 Bytes

• Atomic Serialization: Flushes to a temporary file (.tmp) and commits via atomic filesystem rename, guaranteeing corruption immunity against unexpected process termination.
• Direct GPU Synchronization: Synchronizes active CUDA streams, pulls master FP32 weights into CPU host RAM, and uploads loaded parameters directly to GPU VRAM in nanoseconds.

9. 🔮 Forward-Only Inference Engine ("Use it" / --use)

Axiom features an ultra-low-latency forward inference pipeline that completely bypasses gradient calculation:

• Interactive Real-Time Prompting: Users input natural text prompts (Prompt > ). Axiom dynamically parses, maps vocabulary subwords, and pads/slices into the 128-token context window ($512$ bfloat16 floats).
• Fused Hardware Evaluation: The input context traverses the PCIe bus via DMA and executes on the Ada Lovelace Tensor Cores via fused CUTLASS EVT kernels in microseconds.
• $L_2$ Nearest-Neighbor Decoding: The 4-dimensional predicted embedding $Y \in \mathbb{R}^{1 \times 4}$ is matched against the vocabulary embedding space via Euclidean distance: $$\hat{t} = \arg\min_{t \in \mathcal{V}} |\mathbf{y} - \mathbf{e}(t)|_2^2$$ The nearest token identifier is resolved and formatted directly back to human-readable strings across text, numerical, or multimodal byte tokens.

📊 Hardware Saturation & Telemetry HUD

The Driver-Level CUDA Profiler vs. The CPU Timer Fallacy

Standard benchmarks rely on CPU timers (std::chrono), which are fundamentally flawed for GPU profiling. Because CUDA kernel launches and memory copies are asynchronous, the CPU returns immediately while the GPU is still queued.

Axiom uses hardware-level driver profiling via cudaEvent_t event pairs recorded on active GPU hardware streams. With strict cudaEventSynchronize(stop_event) barriers, timing is calculated at nanosecond accuracy directly by the GPU timer clock:

The Two-Stage Benchmark Architecture Explained

🧮 Mathematical Nucleus

1. Autoregressive Prediction

Given a sequence of multimodal tokens $T = {t_1, t_2, \dots, t_N}$, the objective is to predict the dense embedding vector of token $t_{i+1}$ given the preceding context window of size $C = 128$ tokens: $$X = [\mathbf{e}(t_{i-C+1}), \mathbf{e}(t_{i-C+2}), \dots, \mathbf{e}(t_i)] \in \mathbb{R}^{1 \times K}$$ where $K = C \times D = 128 \times 4 = 512$ elements.

2. Forward Pass (Fused Linear + Non-Linear)

$$Z = X \cdot W^T + \mathbf{b}$$ $$Y = \text{ReLU}(Z) = \max(0, Z)$$ where:

• $X \in \mathbb{R}^{1 \times 512}$ (Context Window)
• $W \in \mathbb{R}^{4 \times 512}$ (Weight Matrix)
• $\mathbf{b} \in \mathbb{R}^{1 \times 4}$ (Bias Vector)
• $Y \in \mathbb{R}^{1 \times 4}$ (Predicted Target Embedding)

3. Loss Formulation

Mean Squared Error (MSE) computed against target token embedding $\mathbf{t} \in \mathbb{R}^{1 \times 4}$: $$L = \frac{1}{2} \sum_{k=1}^{4} (y_k - t_k)^2$$

4. Gradient Derivation & Weight Updates

Using the chain rule: $$\frac{\partial L}{\partial y_k} = y_k - t_k$$ $$\frac{\partial L}{\partial z_k} = \frac{\partial L}{\partial y_k} \cdot \frac{d,\text{ReLU}(z_k)}{dz_k} = (y_k - t_k) \cdot \mathbf{1}{y_k > 0}$$ $$\frac{\partial L}{\partial W{kj}} = \frac{\partial L}{\partial z_k} \cdot x_j = \delta_k \cdot x_j$$ $$\frac{\partial L}{\partial b_k} = \frac{\partial L}{\partial z_k} = \delta_k$$

The SGD parameter update rule: $$W_{kj}^{(t+1)} = W_{kj}^{(t)} - \eta \cdot \delta_k \cdot x_j$$ $$b_k^{(t+1)} = b_k^{(t)} - \eta \cdot \delta_k$$

5. Gradient Stability & Learning Rate Bounds

For a linear step over an unnormalized input vector $X$, the maximum stable learning rate before mathematical divergence is governed by the spectral norm: $$\eta_{\max} = \frac{2}{|X|_2^2 + 1}$$ For 512-dimensional inputs with $|X|_2^2 \approx 50$, any learning rate $\eta > 0.04$ guarantees oscillatory divergence. Axiom sets $\eta = 0.001$, guaranteeing strict monotonic descent.

🛡️ Defensive Systems Engineering

1. The Strict Three-Step Pointer Lifecycle

To guarantee zero VRAM leaks and eliminate dangling pointers, every GPU resource adheres to the Null Guard $\rightarrow$ Free $\rightarrow$ Neutralize protocol:

// 1. Null Guard
if (gpu->d_context_window[i]) {
    // 2. Free
    cudaFree(gpu->d_context_window[i]);
    // 3. Neutralize
    gpu->d_context_window[i] = nullptr;
}

2. Concurrency Safety

• std::atomic<bool> Synchronization: Pinned memory transfers and buffer swaps utilize atomic flags to prevent torn reads across CPU data loader threads and GPU execution streams.
• No Spin-Lock CPU Thrashing: Stream synchronization uses cudaStreamSynchronize and CUDA events (cudaStreamWaitEvent), letting idle CPU threads yield naturally without pegging processor cores at 100%.

3. Clean DLL Encapsulation

The entire CUDA backend compiles into a standalone dynamic link library (cuda_transfer.dll). All GPU internals, __nv_bfloat16 structs, and CUTLASS templates are encapsulated behind an extern "C" API with opaque void* pointers.

• Zero Header Leakage: The CPU application compiles cleanly with GCC 14+ (g++ -std=c++23) without requiring CUDA headers or MSVC compiler extensions.
• Universal Interop: The compiled cuda_transfer.dll can be hooked by Python (via ctypes), C#, Rust, or Electron/Node without exposing internal engine mechanics.

🛠️ Build, Test & Run

Prerequisites

• Operating System: Windows 10 / 11 (64-bit)
• GPU: NVIDIA GPU with Compute Capability $\ge$ 8.0 (Ada Lovelace sm_89, RTX 40-series recommended)
• CUDA Toolkit: v12.x or v13.x (with nvcc on PATH)
• Host Compilers:
  • MSVC Build Tools 2022 (cl.exe v14.40+)
  • GCC 14+ (g++ with -std=c++23 support, e.g., MSYS2 UCRT64)
  • mingw32-make

1. Build the Complete Engine

From the core/ directory:

cd core
mingw32-make all

This automatically invokes:

1. nvcc targeting sm_89 with MSVC cl.exe to compile core/src/CUDA/**/*.cu into cuda_transfer.dll.
2. g++ -std=c++23 to link src/ai.cpp, util/optimizer.cpp, util/parser.cpp, and src/main.cpp against cuda_transfer.dll, producing app.exe and test.exe.

2. Deep Clean Build & Test Artifacts (mingw32-make clean)

To purge all compiled binaries, intermediate objects, libraries, test artifacts, and generated datasets:

mingw32-make clean

Artifacts Purged by clean:

• Executables: app.exe, test.exe, and any temporary test executables (test_*.exe)
• Dynamic & Import Libraries: cuda_transfer.dll, cuda_transfer.lib, cuda_transfer.exp
• Compiler Object Caches: *.o, *.obj, *.exp, *.lib, *.tmp
• Test Scratch Checkpoints: test_*.axiom, corrupt_*.axiom
• Generated Binary Datasets: database/*.bin (e.g., embedded_data.bin) (Note: Pre-trained production checkpoints such as weights.axiom are preserved.)

3. Run the Automated Test Suites (Platinum Guarantee)

Axiom includes 200 automated unit, integration, and resilience tests across 9 comprehensive suites (100% Green, 0 failed):

.\test.exe --test

============================================
  ALL TEST SUITES PASSED (100% GREEN)       
============================================

Test Suite Breakdown:

• test_path: 4 tests (Filesystem directory resolution)
• test_ifstream: 6 tests (Zero-syscall streaming descriptor validation)
• test_embeddings: 14 tests (Deterministic BF16 embedding table invariants)
• test_tokenization: 10 tests (Orthogonal multimodal namespace offsets)
• test_optimizer: 38 tests (4-tier streaming logistics, carry-forward Seam, lock safety)
• test_cuda_transfer: 40 tests (DMA transfers, CUTLASS EVT saturation, backward gradients)
• test_transfer: 7 tests (GPU master weights upload/download roundtrips)
• test_ai: 44 tests (Initialization, convergence, atomic weights.axiom serialization)
• test_inference: 37 tests (Tokenization edge cases, L2 clustering, VRAM leak immunity, corruption rejection)

3. Run the Hardware Benchmark HUD (--benchmark)

To execute the hardware profiler and display the 4-variable Hardware Saturation HUD:

.\app.exe --benchmark

📖 Complete Operator Manual & How-To-Use Guide

Project Axiom is designed to train and infer across multiple modalities with silicon-native precision. This guide breaks down exact step-by-step instructions for every scenario, data type, and runtime mode.

🧭 Operational Modes Matrix

🎨 Detailed Modality Training Scenarios

Scenario A: Training on Pure Text Data

Use this scenario to train the neural network on language patterns, technical documentation, code snippets, or conversational text.

1. Launch .\app.exe (or run .\app.exe --train).
2. At the main menu, type 2 and press Enter for [2] Train it (Training).
3. At the data selection prompt, type 1 and press Enter for [1] Text.
4. Enter your training text (single sentence, paragraph, or long corpus):

   Enter Text:
   Model FLOPs Utilization (MFU) Ceiling: In modern machine learning infrastructure, a realistic MFU target for a well-tuned, dense transformer is 40% to 55%.
   

5. When asked Add media?, select 2 for [2] No.
6. Internal Execution:
   • Text is split into words via whitespace and assigned unique token IDs in the range [1, 9,999,999].
   • If the input sequence is shorter than 129 tokens, Axiom's auto-tiling engine repeats the token stream continuously to satisfy the 128-token sliding context window.
   • Deterministic 4D BF16 vectors are generated and written to database/embedded_data.bin.
   • The continuous training loop starts on GPU Tensor Cores, reporting MSE loss drops every 10,000 steps.

Scenario B: Training on Numerical & Telemetry Data

Use this scenario for scientific sensor data, financial tickers, mathematical streams, or telemetry metrics.

1. Launch .\app.exe and select [2] Train it.
2. At the data type menu, type 2 for [2] Number.
3. Enter space-delimited numerical values (positive floats or integers):

   Enter Number:
   5.1 3.5 1.4 0.2 4.9 3.0 1.4 0.2 4.7 3.2 1.3 0.2 7.0 3.2 4.7 1.4
   

4. When asked Add media?, select 2 for [2] No.
5. Internal Execution:
   • Numerical values are tokenized into the discrete numeric namespace [10,000,000, 19,999,999].
   • The engine maps each unique number to a deterministic 4-dimensional vector, feeds it through the 4-tier pipeline, and learns sequential numeric dependencies.

Scenario C: Training on Image Assets (Computer Vision)

Use this scenario to train the neural network directly on image visual bytes (JPEG, PNG, WebP, BMP).

1. Launch .\app.exe and select [2] Train it.
2. At the data type menu, type 3 for [3] Image.
3. Enter the relative filename, relative path, or full path to the image file or image directory:

   Enter Image Path:
   asset_sample/Photo.jpeg
   

   (Note: Quoted paths with spaces, e.g. "C:\My Assets\Photo.jpeg", and directory paths are fully supported).
4. Internal Execution:
   • Axiom resolves the file path against asset_sample/ and the local filesystem.
   • The image is ingested as raw binary bytes (uint8_t values 0–255), tokenized into the orthogonal visual namespace [20,000,000, 29,999,999].
   • The model trains on byte-level spatial distributions.

Scenario D: Training on Video Assets (Temporal Vision)

Use this scenario to train on temporal visual data (MP4, MKV, AVI video byte streams).

1. Launch .\app.exe and select [2] Train it.
2. At the data type menu, type 4 for [4] Video.
3. Enter the video path:

   Enter Video Path:
   asset_sample/Video.mp4
   

4. Internal Execution:
   • The video stream is read sequentially from disk without syscall overhead.
   • Codec, header, and frame byte sequences are assigned discrete IDs in the video namespace [30,000,000, 39,999,999].
   • The network trains autoregressively on temporal frame byte transitions.

Scenario E: Training on Audio / Voice Assets (Acoustic Waveforms)

Use this scenario to train on voice recordings, music, or acoustic sensor waveforms (OGG, WAV, MP3).

1. Launch .\app.exe and select [2] Train it.
2. At the data type menu, type 5 for [5] Voice.
3. Enter the audio file path:

   Enter Voice Path:
   asset_sample/Voice.ogg
   

4. Internal Execution:
   • Acoustic waveform bytes are mapped into the dedicated voice namespace [40,000,000, 49,999,999].
   • The model learns acoustic spectral representations and audio sequence dynamics.

Scenario F: Multimodal Early Fusion (Text + Media Pairing)

Use this scenario to teach the network associations between language descriptions and raw visual or acoustic data (e.g., image captioning, video description, or voice transcription).

1. Launch .\app.exe and select [2] Train it.
2. Select data type [1] Text.
3. Enter your description text:

   Enter Text:
   High-resolution tactical reconnaissance photograph of forward perimeter airfield.
   

4. When asked Add media?, select 1 for [1] Yes.
5. At the media type menu, choose your modality:
   • [1] Image $\to$ Enter asset_sample/Photo.jpeg
   • [2] Video $\to$ Enter asset_sample/Video.mp4
   • [3] Voice $\to$ Enter asset_sample/Voice.ogg
6. Internal Execution (Early Fusion Pipeline):
   • Text tokens (IDs < 10,000,000) and media byte tokens are concatenated into a contiguous unified sequence.
   • The 128-token context window slides directly across the cross-modal boundary.
   • The network's weights update to predict media representations from textual prefixes (and vice versa).

Scenario G: Scientific Sensor Fusion (Numbers + Media Pairing)

Use this scenario to align numerical telemetry (temperatures, radar distances, time-stamps) with sensor feeds.

1. Launch .\app.exe and select [2] Train it.
2. Select data type [2] Number.
3. Enter numeric readings: 101.3 298.15 45.2 0.98 12.4
4. Select Add media? [1] Yes and choose Image, Video, or Voice.
5. Provide the media path (e.g., asset_sample/Photo.jpeg).
6. Internal Execution:
   • Telemetry tokens are prepended to the media stream. The model learns joint representations between quantitative metrics and perceptual data.

Scenario H: Bulk Dataset Ingestion from asset_sample (Mass Files & Repeat Cycle)

Use this scenario to feed hundreds or thousands of arbitrary files into the model at once without typing individual paths.

1. Place any training files into core/asset_sample/:
   • Text & Notes: .txt, .md, .csv, .json, .py, .cpp, .log, etc.
   • Images: .jpg, .jpeg, .png, .bmp, .webp, .gif
   • Videos: .mp4, .mkv, .avi, .mov, .webm
   • Audio & Voice: .ogg, .wav, .mp3, .flac, .aac
   • Documents & 3D Meshes: .pdf, .obj, .stl, .glb, .bin, etc.
2. Launch .\app.exe $\to$ Select Option [5] Bulk Training (asset_sample), or execute:

   # Continuous bulk training
   .\app.exe --bulk
   
   # Or targeted batch steps with automatic save
   .\app.exe --bulk 50000

3. Internal Execution & Multi-Gigabyte Progress Reporting:
   • Axiom recursively walks core/asset_sample/, sorting all files alphabetically for deterministic execution.
   • Any archive/ subfolder is automatically excluded from directory scans to avoid re-ingesting archived data.
   • For files $\ge 5\text{ MB}$, multi-gigabyte video files, or large archive extractions, Axiom renders a live throttled percentage progress bar:

     [..] Tokenizing Video Video.mp4 [======>                 ] 25.9% (2.0 MB / 7.7 MB)
     [..] Tokenizing Video Video.mp4 [========================] 100.0% (7.7 MB / 7.7 MB)
     

   • Every file's format is automatically detected and mapped into dedicated modality namespaces:
     • ASCII text files are tokenized into vocabulary words ([1, 9,999,999]).
     • Image files stream byte-by-byte into visual tokens ([20,000,000, 29,999,999]).
     • Video files stream into temporal frame tokens ([30,000,000, 39,999,999]).
     • Audio files stream into acoustic waveform tokens ([40,000,000, 49,999,999]).
     • PDFs and 3D models are parsed into spatial byte structures.
   • Embeddings are generated and saved to database/embedded_data.bin.
   • The model automatically detects pre-existing weights at weights.axiom and loads them into VRAM so learning continues cumulatively!
4. Interactive Asset Management (Keep / Archive / Purge):
   • Press [S] anytime to checkpoint current weights, or [Q] to save and exit.
   • Once bulk training completes and model weights are verified, an interactive asset management prompt appears:

     Processed Asset Management (N files):
       [1] Keep files in asset_sample/ (Default)
       [2] Archive processed files to asset_sample/archive/
       [3] Purge (Delete) processed files from asset_sample/
     > 
     

     • [1] Keep files (Default): Retains all files in core/asset_sample/. Non-interactive executions and piped scripts safely default to keeping files.
     • [2] Archive processed files: Moves processed assets into core/asset_sample/archive/. Because archive/ is automatically ignored in all subsequent runs, you can drop fresh data into asset_sample/ without re-processing old files.
     • [3] Purge (Delete) processed files: Emits an explicit safety warning ([!] WARNING: This will permanently delete N file(s)... Are you sure? (y/N)). Confirmation with y permanently frees disk space; any other input cancels the purge and keeps the files.
   • The model retains everything learned in prior batches and adapts seamlessly to new data batches!

⌨️ Runtime Training Controls & Session Lifecycle

During training, Axiom's continuous engine listens for non-blocking keyboard interrupts (_kbhit() / _getch()):

Monitoring Convergence: Every 10,000 steps, Axiom reports live loss metrics:

[Step 10000] loss 0.084120  (-92.3% vs first)
[Step 20000] loss 0.041050  (-96.2% vs first)

A falling loss number and negative percentage prove that the model weights are converging on the training patterns.

🔍 Interactive Inference Session ("Use it")

To run inference and test what the model has learned:

1. Run .\app.exe --use (or select Option [1] from the main menu).
2. Axiom automatically discovers and loads weights.axiom into VRAM.
3. Enter your prompt text:

   Prompt > The quick brown fox
   [Tokens] (4 tokens): 1, 2, 3, 4
   [Tensor Output] [0.0000, 0.0000, 0.1279, 0.0000]
   [Next Token ID] #5
   [Prediction]    "jumps"
   

4. Telemetry HUD Breakdown:
   • Prefill Latency (TTFT): Time-To-First-Token in milliseconds (sub-millisecond on Tensor Cores).
   • Decode Throughput: Generation speed in tokens per second (typically 5,000 to 11,000+ tok/s).
   • Memory Bus Saturation: Real-time bandwidth utilized during token dispatch.
   • Compute Efficiency (MFU): Percentage of theoretical hardware capacity utilized.
5. Type exit, quit, or :q to return or exit.

📊 Hardware Saturation Telemetry Benchmark (--benchmark)

To profile and verify that your GPU's Tensor Cores and memory bus are performing at peak efficiency:

.\app.exe --benchmark

Axiom executes a rigorous two-stage hardware benchmark:

1. Benchmark 1/2 (Inference Dispatch Latency): Measures 100 rapid hardware-timed forward passes of the micro-perceptron model.
2. Benchmark 2/2 (CUTLASS EVT Kernel Saturation): Allocates a transformer-scale 34 MB tensor problem ($M=128, N=4096, K=4096$) and executes 50 hardware-timed fused GEMM + Bias + ReLU passes directly across all Streaming Multiprocessors.
   • On an RTX 4080 Laptop GPU, this demonstrates >50% MFU and >300 GB/s sustained bandwidth saturation.
