Poolside releases Laguna S 2.1, a 118B coding-agent model with 1M context
burny_tech · x · 2026-07-22
Poolside says Laguna S 2.1 is a 118B-A8B open-weight model with a 1M-token context window, built in-house for long-horizon agentic work.
It reports 70.2% on Terminal-Bench 2.1, ahead of several much larger models, and 59.4% on SWE-Bench Pro. The team also says it is releasing the full evaluation trajectories to support the numbers, and that real-world behavior is meant to be resourceful and persistent in coding-agent workflows.
