Summary

Shares Cognition's announcement of SWE-1.7, their most capable model so far. Cognition says it scores within a few points of the strongest frontier models at a fraction of the cost and runs at 1000 tokens/s. They also say that scaling RL with a refined recipe keeps producing gains.

Key points

• SWE-1.7 is Cognition's most capable model to date.
• Scores within a few points of top frontier models at a fraction of the cost.
• Served at about 1000 tokens per second.
• Cognition says RL is 'not hitting its limit': after refining their recipe, gains continue as they scale.
