Best observed unstable manual checkpoint: manual_reasoning_v1_seed42_best_observed_2026-04-02_0435

Exported Best-Observed Unstable Manual Checkpoint

This release packages the strongest single-run result from the manual-curation branch.

• Run: reasoning_manual_v1_seed42_2026-04-01_1315_s768_gc
• Base: d24_asp48_track @ 820230
• Checkpoint step: 300
• Status: best_observed_but_not_promoted

Confirmed metrics

• GSM8K pass@8: 6.70%
• MMLU: 27.60%
• SpellingBee: 0.00%

Why it is not promoted

• This was the strongest single-run reasoning result observed on the project.
• The paired seed in the same sweep failed the promotion rule, so the recipe remained unstable.
• Official project status still keeps mixv2_s768_300 as the provisional champion.

Notes

• This is the strongest single confirmed run on the current d24/r32 chat branch.
• It remains provisional because later exact replication and seed sweeps did not reproduce it reliably.
• The original unsplit archive remains available locally in ~/nanochat-learn/exports/.
• GitHub docs currently state each release file must be under 2 GiB.
