contrary to popular believe, integrating sonnet 4.5 into your app is not a one line model string change! some things we learned at cognition from using 4.5 early in devin (long running agent) and windsurf
We rebuilt Devin for Claude Sonnet 4.5. Available starting today as an Agent Preview that’s over 2x faster and 12% better on our Jr. Developer Evals.
Claude Sonnet 4.5 is now available in Windsurf. The model's ability to maximize actions through parallel tool execution makes Cascade Agent runs dramatically faster and more effective. Now available for 1x credits to individual users for a limited time.
Excited to share that OpenAI’s GPT-5-Codex is now live in Windsurf! We’re making it free to paid users for a limited time. We can’t wait to hear what you build with it!
california is literally heaven
how's @windsurf been for you recently? passing along bug reports directly to engineers - prioritizing detailed replies with error messages, screenshots, etc.
Introducing code-supernova, a versatile agentic coding model that supports image inputs. 200k context window. Now available for individual users for free for a limited time. We’re excited to hear what you think!
Windsurf now has queued messages! Send follow-up messages for Cascade to pick up when it's done with the current task.
The @cognition & @windsurf teams have been grinding since day 1 of the merger. We were finally able to get the teams from around the globe together this week in the Bay. A lot of work ahead but the way the companies have come together feels special. More innovation to come 📈.
Devin will read your agents.md files!
The future that Cognition will unlock is unfathomable and it will be known as one of the most important AI and reasoning labs in the world This company will unlock monumental human achievement So excited to be an investor of this company and their raw competitive nature…

When we started Cognition, we were a small group of engineers who shared a lifelong love of coding. We hunkered down in an apartment in NYC and built the product we always wanted for ourselves. A lot has changed over the last 20 months but the core vision has not. We see a…

Surprised how many people are missing the point here. If the goal is to move from 40% -> 50%, it is because the underlying goal is more adoption of AI tooling by the engineers and skill in the tools. Great engineering leaders know this is how they outpace the growing competition.
