most of the time deepswe bench is judged on the cost, but the agent steps per task is more interesting because it shows how much slop you will get. my day to day experience confirms this too.
Today we’re releasing DeepSWE, a new standard for agentic coding benchmarks.
On public leaderboards, top models often look relatively close in capability. DeepSWE shows where they actually diverge, reflecting the realistic experience of developers in their day-to-day work.
Meta’s Muse Wonder now leads on DeepSWE.
This is an incredible turnaround only 14 months after the announcement of Meta Superintelligence Labs.
We have a new model on the frontier.
I have 40+ complete runs of DeepSWE from different Qwen3.8 27B models, Flash Next, and MiMo V2.6.
Next, I plan to use one of these models to aggregate the trajectories to produce better results.
I saw several papers at COLM about this. It seems to work.
I'll do the same with Terminal Bench 4.0. I have completed 15 runs so far.
