Root cause fixes over v0.4: transient API errors were cached as permanent failures (127/530 prompts lost) and training text lacked Qwen special tokens. Model loads go CPU-first in bf16 — safetensors direct-to-GPU and fp16-at-load crash the current torch nightly on Windows. --- .env.example | 15 ++ .gitignore | 39 +++- chat.py | 115 ------------ config.py | 79 -------- download_model.py | 23 --- download_student.py | 19 -- evaluate.py | 101 ---------- evaluate_extended.py | 159 ---------------- format_dataset.py | 93 --------- gen_batch.py | 68 ------- generate.py | 67 ------- generate_data.py | 108 ----------- pyproject.toml | 38 ++++ src/distill/__init__.py | 3 + src/distill/chat.py | 82 ++++++++ src/distill/config.py | 224 ++++++++++++++++++++++ src/distill/dataset.py | 210 +++++++++++++++++++++ src/distill/download_student.py | 35 ++++ src/distill/eval_metrics.py | 61 ++++++ src/distill/evaluate.py | 282 ++++++++++++++++++++++++++++ src/distill/export_gguf.py | 124 ++++++++++++ src/distill/generate_dataset.py | 273 +++++++++++++++++++++++++++ src/distill/logging_utils.py | 54 ++++++ src/distill/merge.py | 46 +++++ src/distill/model_loading.py | 43 +++++ src/distill/safetensors_pretouch.py | 49 +++++ src/distill/teacher_client.py | 212 +++++++++++++++++++++ src/distill/train.py | 179 ++++++++++++++++++ test_connection.py | 43 ----- test_model.py | 43 ----- tests/test_dataset.py | 146 ++++++++++++++ tests/test_eval_metrics.py | 87 +++++++++ tests/test_generate_dataset.py | 148 +++++++++++++++ tests/test_teacher_client.py | 153 +++++++++++++++ train_student.py | 184 ------------------ 35 files changed, 2500 insertions(+), 1105 deletions(-) delete mode 100644 chat.py delete mode 100644 config.py delete mode 100644 download_model.py delete mode 100644 download_student.py delete mode 100644 evaluate.py delete mode 100644 evaluate_extended.py delete mode 100644 format_dataset.py delete mode 100644 gen_batch.py delete mode 100644 generate.py delete mode 100644 generate_data.py create mode 100644 pyproject.toml create mode 100644 src/distill/__init__.py create mode 100644 src/distill/chat.py create mode 100644 src/distill/config.py create mode 100644 src/distill/dataset.py create mode 100644 src/distill/download_student.py create mode 100644 src/distill/eval_metrics.py create mode 100644 src/distill/evaluate.py create mode 100644 src/distill/export_gguf.py create mode 100644 src/distill/generate_dataset.py create mode 100644 src/distill/logging_utils.py create mode 100644 src/distill/merge.py create mode 100644 src/distill/model_loading.py create mode 100644 src/distill/safetensors_pretouch.py create mode 100644 src/distill/teacher_client.py create mode 100644 src/distill/train.py delete mode 100644 test_connection.py delete mode 100644 test_model.py create mode 100644 tests/test_dataset.py create mode 100644 tests/test_eval_metrics.py create mode 100644 tests/test_generate_dataset.py create mode 100644 tests/test_teacher_client.py delete mode 100644 train_student.py diff --git a/.env.example b/.env.example index 0c71bf0..bcee386 100644 --- a/.env.example +++ b/.env.example @@ -1,3 +1,18 @@ # 9Router API credentials — copy this file to .env and fill in your values API_BASE_URL=http://127.0.0.1:20128/v1 API_KEY=your-9router-api-key-here + +# Optional overrides (defaults live in src/distill/config.py) +# TEACHER_MODEL=cx/gpt-5.5-xhigh +# JUDGE_MODEL=cx/gpt-5.5-high +# STUDENT_MODEL_ID=D:/models/qwen15-1.5b +# MAX_SEQ_LENGTH=1024 +# NUM_EPOCHS=3 + +# GGUF export tooling (machine-specific paths) +# LLAMACPP_BIN=D:/tools/llama-cpp-b10107 +# LLAMACPP_SRC=D:/tools/llama.cpp-src + +# Inference service (services/api) +# MODEL_PATH=checkpoints/gguf/distill-gpt55-v0.5-Q4_K_M.gguf +# CORS_ALLOW_ORIGINS=http://localhost:3000 diff --git a/.gitignore b/.gitignore index 3b8aaa5..c3e6174 100644 --- a/.gitignore +++ b/.gitignore @@ -4,19 +4,29 @@ __pycache__/ *.egg-info/ dist/ build/ +.pytest_cache/ +.ruff_cache/ -# Models & checkpoints (quá nặng) +# Models & checkpoints (too heavy for git) checkpoints/ models/ *.bin *.safetensors *.pt *.pth +*.gguf -# Dataset raw +# Dataset data/raw/ data/processed/ +# Logs +logs/ + +# Node +node_modules/ +services/web/dist/ + # IDE .idea/ .vscode/ @@ -26,7 +36,30 @@ data/processed/ .DS_Store Thumbs.db -# Environment +# Environment & secrets .env +.env.* +!.env.example venv/ .venv/ + +# Assistant tooling & private dirs (never commit) +.claude/ +.codex/ +.commandcode/ +.claude-private/ +.private/ +AGENTS.md +CLAUDE.md + +# Private notes / drafts (root-level;
