Conventional model routing sucks. It passes benchmarks but fails to write code you'd actually merge.
Introducing Devin Fusion, a new hybrid-model harness for agentic coding.
In testing, it reduces the cost of Fable-level intelligence by 35% and still feels good to use.

Devin tests its work before you review the PR.
You review and approve the test plan.
Then get back a screen recording with a visual checklist of step-by-step QA.

Saw this Wednesday and immediately knew we needed our own. So we built it: an internal Quick for everyone at @Courtyard_io to ship and share sites just as fast - but git-backed, behind SSO, in our own style. Live 24 hours later, built with @cognition's @DevinAI.
Since Quick launched in July 2025, we’ve collectively built more than 50,000 sites. Over 50% of employees have at least one Quick site.
When you remove the barriers to build & share, it’s incredible what happens.
More examples of how we’re using Quick :

We’re removing access to Claude Fable 5 in Cognition products following Anthropic’s latest announcement and the US government directive to suspend access.
All other models remain available in Devin, including Claude Opus 4.8 and GPT-5.5.
Devin Ultra mode will continue to use the most powerful available models.

Last week we introduced the AI Productivity Guarantee: a $10,000,000 bet that Devin delivers engineering value.
Today, @ryanbai walks you through how we calculate, benchmark, and guarantee it:

Congratulations to @axliu42 on receiving the ACM Doctoral Dissertation Award for his work on learning-theoretic foundations for understanding quantum systems.
Allen joined Cognition's research team this week while continuing as a professor at NYU. We’re honored and excited to work with him.
nitter.app/TheOfficialACM/status/…
Congratulations to Allen Liu, who received the ACM Doctoral Dissertation Award for his dissertation “Learning Theoretic Foundations for Understanding Quantum Systems,” toward a PhD earned at the @MIT .
Liu’s thesis reshapes our understanding of quantum systems through perspectives in learning theory. The quantum computing community is still trying to unravel the far-reaching implications of his work.
Honorable Mentions go to Gal Arnon for his dissertation “New Advancements in Interactive Oracle Proofs: Theory, Practice, and Limitations” toward a PhD earned at the Weizmann Institute of Science; and Rachit Nigam for his dissertation “Modular Abstractions for Efficient Hardware Design,” toward a PhD earned at @Cornell .
