# Blaster-Think

**Blaster-Think** is a **snapshot of the v35 hearing ship tip** (`checkpoint-116000`) plus the Loop 2 typed-think **decode contract**. Weights are the same merged serving export as live Blaster at that tip. Thinking is **not** extra LoRA in this dump: the gateway prefills `Answer: <think>` on cued math and strips the span before TTS.

This repo is a **separate Hub model** so later GRPO / dual-LoRA work cannot overwrite the hearing ship:

| Do not overwrite | This snapshot |
| --- | --- |
| [`molmo-audio-serving-diar-d`](https://huggingface.co/0x8badbeef/molmo-audio-serving-diar-d) | **this repo** |
| [`molmo-audio-lora-diar-d`](https://huggingface.co/0x8badbeef/molmo-audio-lora-diar-d) | [`molmo-audio-lora-blaster-think`](https://huggingface.co/0x8badbeef/molmo-audio-lora-blaster-think) |

`SERVE_TIP` on the live box stays `outputs/molmo-audio-lora-diar-d-v35/checkpoint-116000`. Think CE at `117500` was **aborted** (hearing dual-eval `HEARING_NO_SHIP`). Do not serve `117500`.

## What’s inside

Same files as the diar-d serving merge (`model-*-of-*.safetensors`, `audio_modules.pt`, tokenizer, remote-code sources), plus:

| Path | Purpose |
| --- | --- |
| `serving/think_scaffold.py` | Loop 2 P0/P1 cue, 192-token body, force-close, loop XOR |
| `eval/think_eval_116000_gsm_192.json` | Scaffolded GSM heldout at this tip |
| `SNAPSHOT.json` | Pin: tip id, parent, abort notes |

## Think eval (this tip, scaffolded GSM, n=20)

| Gate | Result |
| --- | --- |
| Format (`<think>`…`</think>`) | **20/20** |
| Exact | **8/20** (worded finals and a few real misses; not a ship gate for think) |
| Unearned correct | 0 |
| Uncued leak | 0 |

Exact is a **format contract + weak arithmetic**, not a reason to invert training from base Molmo-7B-D.

## Intended use

- Restore this exact 116000 merge if GRPO or a second think LoRA goes wrong
- Research on cued typed thinking **without** replacing live Blaster
