Jeff-Code runs two adapters on the fixed Jeff v1.3 base: [`code`](https://huggingface.co/mstrasser/jeff-adapter-code) takes the information-gathering steps (step threshold 0.40), and [`code-router`](https://huggingface.co/mstrasser/jeff-adapter-code-router) decides whether Qwen thinks hard on a turn (thinking off unless P(xhigh), out of the four levels off/low/medium/xhigh, ≥ 0.6). The baseline is Qwen3.8-27B alone in the same Jeff-Code build with every Jeff feature off, thinking at full on every turn and no thinking limit, which is how plain Pi runs it. Each task ran in both settings side by side, at the same time on the same Qwen server, and every comparison is paired by task. Only tasks Jeff never saw in training were used: the held-out splits of six benchmarks.
