# Stage 1 state
|
|
|
|
Task: `docs/stage1-training-task.md`. Settings and weights: `train/README.md`. Updated 2026-10-03 22:40.
|
|
|
|
## Done
|
|
|
|
- Step 0 (setup): `train/.venv` (Python 3.11.17, uv), `mlx-lm` 0.32.0 / `mlx` 0.32.3.
|
|
Model `mlx-community/Qwen3.8-27B-4bit` at `~/models/Qwen3.8-27B-4bit` (affine 4 bit, group 64, 16.1 GB;
|
|
base `Qwen/Qwen3.8-27B`). The Ollama NVFP4 weights do not load in mlx_lm (global scale).
|
|
- Server: `train/serve.sh` (`mlx_lm.server`, port 8080, thinking on with `reasoning_effort` medium,
|
|
temperature 0.2, top_p 0.95, top_k 20, min_p 0, max tokens 32768). Tool-call test passed.
|
|
- Eval subset (Kral decision): `train/subset.json` (copy `runs/stage1/subset.json`), 25 tasks. The task
|
|
document says "all accepted tasks" for step 2; Kral changed it to this subset. Use the same list after
|
|
training.
|
|
- Runner: `train/baseline.py --label <label>` (one task at a time, results `runs/stage1/<label>.json`,
|
|
run directories `runs/stage1/<label>/`).
|
|
|
|
- Step 1 done (2026-10-03 22:20, Kral decisions applied, strict dedup rule): `train/prepare.py`, report
|
|
`train/data/report.md`. Corpus: SAP-samples/abap-cheat-sheets (Apache-2.0), 370 records, 2.81M real tokens.
|
|
Version dedup: main (ABAP Cloud) and the newest v* (Standard ABAP) always kept; each older v* is compared with
|
|
the next newer v* and kept only if more than 5 % of lines differ. 335 object versions: 323 kept, 12 removed.
|
|
Tokens 2,806,501 -> 2,658,082 after dedup. Documents over 16384 are split, not removed: 41 documents -> 82
|
|
pieces (classes at ENDMETHOD, markdown at "##"; 15 blocks needed a line cut); tokens after split 2,660,834;
|
|
no piece over the limit. Token share: DOC 49.0 %, CLAS 46.9 %, other 4.2 %.
|
|
Train 374 docs / 2.53M tokens, valid 20 docs / 135k tokens (split by family, seed 20261003).
|
|
**748 iterations for 2 epochs** (the count is the same as with the first dedup rule by coincidence).
|
|
`test.jsonl` = copy of valid.
|
|
|
|
## Running (detached)
|
|
|
|
- MLX server PID 66098 (not restarted), log `runs/stage1/server.log`.
|
|
- Baseline on the 11-task subset (`train/subset.json`; the 25-task subset is `train/subset_v1_25.json`), started
|
|
2026-10-03 22:36 by `train/baseline_chain.sh` (PID 69101; python PID 69107), logs `runs/stage1/baseline_chain.log`
|
|
and `runs/stage1/baseline.log`. Settings: max_tokens 16384, reasoning medium, budget 60 (`train/README.md`).
|
|
macOS notification after 2 tasks ("ask for the time estimate") and at the end ("Baseline (11 tasks) ended").
|
|
- The earlier night chain (25 tasks) was stopped with its first T01 run (aborted at 33 tool calls after 2 h;
|
|
A4H objects deleted; directory `runs/stage1/baseline/_aborted_20100_T01`).
|
|
|
|
## Next
|
|
|
|
0. After the baseline ends: Step 3 training test (20 iterations), Kral stops A4H first and the MLX server is stopped.
|
|
|
|
1. B2: read the last lines of `runs/stage1/baseline.log`; summary from `runs/stage1/baseline.json`
|
|
(`t01_test_budget40` holds the T01 test result). Commit.
|
|
2. Step 2, second part: valid loss of the base model (`mlx_lm.lora --test`, no adapter) after the baseline.
|
|
3. Step 2, second part: valid loss of the base model (`mlx_lm.lora --test` without adapter; check the
|
|
options with `--help` first). Add it to `runs/stage1/baseline.json`.
|
|
4. Step 3 (training): Kral stops A4H; stop the MLX server; no other model loaded. Short test of 20
|
|
iterations first.
|
|
|
|
## Notes
|
|
|
|
- The earlier T01 score 41.7 (run 103) used the Ollama NVFP4 weights. The baseline of 2026-10-03 (MLX 4 bit)
|
|
is the new reference.
|
|
- Harness changes that matter for stage 1 runs: ADT activation fallback for PROG/FUNC (EPOD bug), G2 finds
|
|
the FUNCTION statement after local classes, call budget floor 60, empty-turn retry in the agent
|
|
(`max_tokens` only for cloud models; the MLX server limit is `--max-tokens 32768`).
|
|
- Session 2026-10-03 (evening): follow-ups of `docs/devir-notlari.md` section 3 done from stored results
|
|
(review of 10 + 10 tasks, easy candidates, docs). No model run was started. Reruns wait in
|
|
`runs/stage1/rerun_queue.txt` (G0119, G0162) until the baseline ends.
