Poolside Opens Laguna S 2.1 To Rival Models 13 Times Its Size
Laguna S 2.1 activates just 8 of its 118 billion parameters per call, a mixture-of-experts model scored on Terminal-Bench 2.1.
- 118 billion total parameters, 8 billion active per token, weights released openly.
- Poolside says Laguna S 2.1 rivals models above 1.6 trillion parameters on Terminal-Bench 2.1.
- Pitched as the strongest agentic coding model in its weight class, not a chat model.
Why it matters: The only judge of whether Laguna S 2.1 rivals a 1.6-trillion-parameter model is the company that built it.
