Public weights
Yes Hugging Face model repositoryVibeThinker-3B Agentic Distilled
The experiment asked whether a reasoning-strong 3B base could become a better tool-calling student than Qwen3-4B. The fused weights were published, but the repository does not preserve a current before/after eval, regression review, or ship decision. This page is the honest case study of an unfinished proof: the artifact exists; the conclusion does not.

| VibeThinker-3B MLX base | historical GSM8K sanity slice | 40/40 | 3B | Directional | Shows the source base's reasoning signal, not retained reasoning after agentic distillation. |

Direct rows share this artifact's eval setup. Directional rows are useful market context but should not be read as leaderboard claims.

Release Blockers
No current before/after eval
Public weights alone cannot establish whether tool-calling improved or whether reasoning regressed.
Unblock: Freeze a matched baseline, agentic primary gate, and reasoning/breadth regression gate; then run both once under the same harness.
No specialist package or routing decision
The repository has no canonical package metadata that defines safe use or a ship/reject outcome.
Unblock: Only package after the frozen eval produces a defensible decision.
