Points for Critical Review + +1. **RoPE Order in Fused Path**: Verification that `apply_rotary_pos_emb` is correctly applied to `q` and `k` *after* projection norms but *before* the fused scoring logic. +2. **Outlier Scattering**: In `TurboQuantCache._add_outliers`, check the robustness of the `scatter_` operation for multi-head GQA (Grouped Query Attention) where head dimensions might be interleaved. +3. **Triton Bit-unpacker**: In `TurboQuant_prod_kernel`, verify that the bit-offset logic for 3-bit indices (not power-of-two) doesn't cause alignment issues across blocks. +4. **Scaling factors**: Ensure the normalization factors (e.g., `sqrt(pi/2)/d`) in the QJL correction are numerically stable for different head dimensions (e.g., 128 vs 96). + +## 4. Current Test Results +- **Quality**: 100% Top-1 agreement on Gemma-4-E2B and Llama-3-8B. +- **Compression**: Up to 4.9x (3-bit mode) for Key Cache. +- **Connectivity**: Fully compatible with `model.generate(past_key_values=cache)`. + +--- +*Summary prepared by Antigravity AI for Vincent's TurboQuant Project.* diff --git a/examples/apu_gemma_demo.py b/examples/apu_gemma_demo.py new file mode 100644 index 0000000..126e1ce --- /dev/null +++ b/examples/apu_gemma_demo.py @@ -0,0 +1,69 @@ +import torch +import time +from transformers import AutoModelForCausalLM, AutoTokenizer +import os +import sys + +# Injonction du chemin racine pour trouver tq_impl +root = os.path.abspath(os.path.join(os.path.dirname(__file__), '..')) +if root not in sys.path: + sys.path.insert(0, root) + +from tq_impl import AutoTurboQuant + +# Configuration pour APU/CPU +MODEL_ID = 'google/gemma-4-E2B-it' +DEVICE = 'cpu' + +def run_apu_demo(): + print(f'--- OPEN TURBOQUANT: APU/CPU DEPLOYMENT DEMO ---') + print(f'Target Model: {MODEL_ID}') + print(f'Forcing Device: {DEVICE.upper()}') + + # 1.
