Yolop’s model suggestions for OpenAI and OpenRouter now include `gpt-6.1-sol`, `gpt-6-sol`, `gpt-6-luna` and `gpt-6-astra`. Anthropic and OpenRouter suggestions add `claude-opus-5-5`, `claude-sonnet-5-5` and `claude-fable-5-1`, with their 1M-context variants where the registry has them.

A new `speed` setting picks OpenAI’s service tier for models that offer one, and a tier the model does not offer is skipped:

```bash
yolop config set speed fast
```

`YOLOP_SPEED` sets it for one run.
