    Introducing SWE-1.7, the most capable model we’ve trained yet. It scores within a few points of the strongest frontier models at a fraction of the cost, and is now available at 1000 tok/s. RL is not hitting its limit: after refining our recipe, we keep seeing gains as we scale

    The FrontierCode leaderboard is now live: a dedicated page that tracks which models are writing code you’d actually merge. All scores — including Grok 4.5 and Inkling — are available, along with full methodology and sample tasks.

    One year ago today, Cognition acquired Windsurf. In the year since, we've shipped dozens of new features, added hundreds of millions of dollars in ARR, and published frontier AI research. @ScottWu46 and @jeffwang share what we've accomplished in one year of building together.

    As of today, Devin Fusion now incorporates Fable 5. Surprisingly, Fable 5 runs at a lower cost per task than Opus 4.8. Even though it’s a more expensive model, we observed cost efficiency improvements in areas like delegation and reasoning chains.

    Making Fable Cheaper Than Opus
    We replaced Opus 4.8 with Fable 5, and Devin’s bill went down. Fable 5 costs twice as much per token as Opus 4.8. But when we ran both models on FrontierCode 1.1 using our new Fusion architecture,...

    While early results are promising, cost savings are not uniform across all tasks. For example, serial debugging tasks necessitate accumulated context to trace the error. We’re excited to continue improving routing and delegation in the Fusion harness.

    Yesterday we launched SWE-1.7 built on the open-source Kimi K2.7. Concerns about Chinese base models are real: K2.7 completed 87% of tasks that other models refuse over human-rights concerns. We trained SWE-1.7 specifically on trustworthiness, so it matches US models on evals.

    For coding agents, trustworthiness has to be tested in the harness where the model actually writes code. In one surveillance scenario, Kimi K2.7 complied with the request in 8/8 samples. SWE-1.7 refused in 8/8, identifying the civil-rights and privacy issue instead.

    As a result, we can show that open-source-derived models are not inherently untrustworthy. They can be suitable for production agents with careful development, realistic evals, and targeted mitigations. Read more in our blog post:

    Measuring the Trustworthiness of Open-Source-Derived Models
    We built an evaluation suite to assess model trustworthiness. Our results indicate that models developed from open-source models can be trusted, provided that sufficient thought and care is put into...
