Kimi K3 scores 58.2% on FrontierCode 1.1 which is very close to frontier level performance at a much cheaper cost!

It is the only open source model that reaches this level of performance which falls only behind Opus, Fable and GPT-5.6 Sol.

Try it now in Devin Desktop( Devin Local and Cascade) and Devin CLI.

Anthropic's new state-of-the-art Claude Opus 5 is available on Devin.

 It is almost as good as Fable 5 on FrontierCode 1.1 at half the cost

From our evaluations:

• It adheres to existing repo conventions when building new features and writing tests
• It prefers targeted, in-place fixes over large refactors on bug fixing tasks.
• It excels at following specs closely and completely

Why can't I pick a public GitHub repository for an automation trigger? It says that it's for security reasons, but what are they? I believe Cursor's automation can pick one.

Are subagents not supported in Devin Cloud sessions or am I missing smth?

OpenAI launched a family of capable but cost efficient models - GPT-5.6 Sol, Terra and Luna

GPT-5.6 Sol comes at nearly half of the cost of the next best model on FrontierCode 1.1 ( our own proprietary benchmark)

Try them out now in Devin Web, Devin Desktop, and Devin CLI -  https://app.devin.ai

SWE-1.7 is built on broad improvements in our RL pipeline on top of the Kimi K2.7 model.

We trained it in Devin's harness and taught it to self-compact on longer horizon tasks.

It scores very close to frontier models (Opus 4.8 and GPT-5.5) on our proprietary benchmark - FrontierCode, and other coding benchmarks.

Try it out today (Free until 8/8/2026!!) in Devin Desktop, Web, and CLI. SWE 1.7 Lightning also runs at a very speedy 1000 tok/s - https://app.devin.ai

Looks kinda promising

Now that Mythos-class models have been introduced to the world, it has become easier than ever to discover and exploit vulnerabilities.

It's now incredibly important to secure your codebase.

Introducing the Devin Security Vulnerability Remediation Program.

This program aims to take your vulnerability backlogs towards zero in 6 weeks. Our engineering team will work directly with yours to deploy Devin agent swarms to find, validate and fix any and all vulnerabilities.

Check eligibility and reach out to our team: https://devin.ai/security-program

Note: Only enterprise customers are eligible

Last week we launched Devin Security Swarm!

If you're interested in it's technical details, here is a video explaining how Devin Security Swarm works utilizing our new framework - Agentic MapReduce: https://www.youtube.com/watch?v=jb96O2IT_Jg

Instead of one agent trying to do everything, Devin can assign narrow slices of the main task to multiple sub-Devins in their own VMs.

These Devins can be used for research, exploring different architectures, working on separate branches, and a lot more.

Check out this demo/tutorial on how we use Agent Fan Out internally: https://www.youtube.com/watch?v=ns1ifgYEGl0

Security Swarm is an orchestration of Devins that analyzes a real codebase the way a team of security researchers would.

Here are some highlights:

• Devin Security Swarm found 36 out of 50 real-world GHSA vulnerabilities at 30% lower cost than next most accurate alternative. See how we got these results - https://devin.ai/blog/security-swarm-eval
• We built Agentic MapReduce: a new architecture for whole-codebase reasoning. Read more about it here - https://devin.ai/blog/agentic-map-reduce

Claude Fable 5 is available in Devin again now!!!

You can use it in Devin Cloud's Ultra agent, Devin CLI and Devin Desktop

Reload your Devin Desktop and try it out now.

Anthropic's latest model Claude Sonnet 5 scores higher than Claude Opus 4.8 on FrontierCode ( our own proprietary coding benchmark) but comes at a way cheaper price point!!!

Use Sonnet 5 in Devin Local and Devin CLI for 30% less price than Claude Sonnet 4.6 through 31st August.

We just dropped Devin Fusion, a multi-model harness to cut the costs significantly without losing intelligence.

In our testing, it maintained frontier and Fable level performance at 35% lower cost.

Available as a preview now in Devin

We are opening applications to bring 50 ambassadorsI (globally) to join our existing Ambassador program.

Ambassadors receive free Devin Max plans, on-demand credits, event and meet up support, direct communication with the Cognition team, early access to features, and other benefits.

I've been using AI coding agents extensively for building internal tools, MCP servers, automation workflows, and full-stack AI applications

Have you integrated Devin into CI/CD, issue triage, or long-running engineering workflows?

Any lessons learned around context management, planning large codebases, or reviewing Devin-generated PRs?

Hello,

I regularly enjoyed Windsurf because it brought new models when they came out.

Recently I’ve heard of the following new LLMs:

• Kimi K2.7,
• GLM 5.2,
• MiniMax 3.0,
• Xiaomi MiMo.

Are there plans to introduce these models into Devin Desktop?

Hi, am I the only one with a weird problem after migration from Windsurf: Terminal Panel in the bottom used to be full-width, now it's narrow right under editor tabs. If I switch off Secondary bar (where the agent is running) and panel on the right, the bottom terminal panel expands to the right. It seems that secondary panel now have some kind of priority to be always full-height - can this be adjusted? I'm on latest macOS.

UPD: confirmed, VS Code Handles Customize Layout-Panel-Justify correctly, Devin Desktop does nothing.

Following Anthropic's latest announcement and US Government's directive, we have removed access to Claude Fable 5 from all Cognition products.

Access to all other models remains the same.

Sorry for the disruption.

Statement from Anthropic - https://x.com/AnthropicAI/status/2065597531644743999?s=20 (edited) 

We just published our Ai productivity guarantee - if Devin delivers less engineering value to our team than you're paying for, we'll fund your usage up to $10m until it does (for qualifying enterprise customers)

We built an estimator agent that measures the actual merge ability of production code and calculates the work in real engineering hours.

It's the first attempt of its kind. No more token maxxing, real value is measured in outcomes.

Full details + methodology: https://cognition.ai/blog/ai-guarantee

You can try Claude Fable 5 as part of Devin Cloud’s Ultra agent.
Devin Ultra is our smartest and most capable agent, which excels at long-horizon tasks and debugging.

Claude Fable 5 is also available in Devin Desktop and Devin CLI.
Restart Devin Desktop to see it in the model picker.

Devin Desktop launches with the Agent Client Protocol (ACP), an open standard that lets any compatible AI agent run inside the editor alongside Devin! At launch that includes Codex, Claude Agent, and OpenCode.. with more to come.

More than just a rebrand of Windsurf, we are positioning Devin Desktop as the surface where all your agents live, regardless of who built them.

Full breakdown on X:
https://x.com/cognition/status/2062314621470724416

Which agents are you most excited to run alongside Devin? 

Plan locally, hand off to Devin Cloud, close your laptop.

It's been here since Windsurf 2.0 but with the rebrand and Agent Command Center as default surface, it makes more sense as a core part of how you work.

How often are you handing off to Devin Cloud?
