DwarfStar’s laguna-s2.1 branch now includes a GPT-5.6-Sol implementation
Antirez says the DwarfStar laguna-s2.1 branch now contains a GPT5.6-Sol-coded implementation of Laguna S2.1, which was also manually tested for apparent sanity on non-trivial tasks.
He reports performance numbers on an M5 Max:
- 50 tokens/s generation
- 500 tokens/s prefill
- Metal only for now
He adds that GPT5.6 Sol can write the other backends for you, implying the model is being used as a practical coding assistant inside the project’s implementation workflow.
