Devin Desktop Updates & Release Notes

Devin Desktop Sep 25, 2026Revenue milestone

Devin's maker Cognition says its annualized revenue passed $1 billion

Bloomberg reported on September 25, 2026 that Cognition, the maker of Devin and Devin Desktop, said its annualized revenue run rate has passed $1 billion. That is roughly double the $492 million run rate it reported in May 2026, when it last raised money, and follows a $2 billion Series E round on September 8 that valued the company at $48 billion. An annualized run rate takes a recent month or quarter of revenue and projects it across a full year, so it is a snapshot of momentum rather than money already booked over a full year.

Your move: A revenue milestone, not a Devin Desktop product change

Bloomberg reported on September 25, 2026 that Cognition, the maker of Devin and Devin Desktop, said its annualized revenue run rate has passed $1 billion. That is roughly double the $492 million run rate it reported in May 2026, when it last raised money, and follows a $2 billion Series E round on September 8 that valued the company at $48 billion. An annualized run rate takes a recent month or quarter of revenue and projects it across a full year, so it is a snapshot of momentum rather than money already booked over a full year.

Why it matters

This is a business milestone, not a change to Devin Desktop itself, so nothing changes in how the product works today. It does show Cognition has plenty of funding and growing enterprise demand behind it, which is a reasonable sign of staying power if you are relying on Devin Desktop for real work.

Devin Desktop Sep 24, 2026v3.10.35

Devin Desktop fixes a startup crash on new Apple M6 Macs

Cognition released Devin Desktop v3.10.35 on September 24, 2026, fixing a bug that made the app crash at startup on Macs with Apple's new M6 chip. The update also fixes a memory leak in the agent command center, a folder-selection bug on SSH and WSL hosts, and makes MCP servers passed in through an ACP client's session usable by the agent.

Your move: Update now if Devin Desktop won't open on an M6 Mac

Cognition released Devin Desktop v3.10.35 on September 24, 2026, fixing a bug that made the app crash at startup on Macs with Apple's new M6 chip. The update also fixes a memory leak in the agent command center, a folder-selection bug on SSH and WSL hosts, and makes MCP servers passed in through an ACP client's session usable by the agent.

Why it matters

If Devin Desktop has been crashing on launch on an M6 Mac, update to v3.10.35 to fix it. Everyone else gets the memory-leak and folder-selection fixes as a routine improvement.

Devin Desktop Sep 21, 2026New model

Devin Desktop adds xAI's Grok 4.7 model

Cognition added xAI's newly released Grok 4.7 model to both Devin Desktop and the Devin CLI on September 21, 2026. Cognition's own testing found Grok 4.7 does best on hard, multi-module backend tasks in languages like Java, Go, and Ruby, where it digs into dependencies and checks its own work with real tests. But on Cognition's overall benchmark, it scored lower than Grok 4.6 because it tends to change more code than a task actually asks for. It costs and runs at the same speed as Grok 4.6.

Your move: Strong on hard backend tasks, but tends to change more than asked

Cognition added xAI's newly released Grok 4.7 model to both Devin Desktop and the Devin CLI on September 21, 2026. Cognition's own testing found Grok 4.7 does best on hard, multi-module backend tasks in languages like Java, Go, and Ruby, where it digs into dependencies and checks its own work with real tests. But on Cognition's overall benchmark, it scored lower than Grok 4.6 because it tends to change more code than a task actually asks for. It costs and runs at the same speed as Grok 4.6.

Why it matters

Devin Desktop users now have another model to choose from, but Cognition's own numbers say to expect larger, less-targeted changes than you'd get from Grok 4.6. Keep an eye on the diffs it produces, especially on tasks where you want a small, contained fix.

Devin Desktop Sep 16, 2026v3.10.31

Devin Desktop fixes a critical inherited VS Code security bypass

Cognition released Devin Desktop version 3.10.31 on September 16, 2026. It fixes a bug in Restricted Mode, a feature meant to block certain workspace settings from running automatically. The bug, tracked as CVE-2026-81376, let a workspace slip past that block by writing the settings in a nested object format instead of the usual one. Microsoft found the same underlying flaw in Visual Studio Code itself and rated it a near-maximum severity score. Devin Desktop inherited the bug because it is built on a fork of VS Code. The release also makes your 10 most recently viewed sessions show their transcripts immediately when you return to them.

Your move: Update to 3.10.31 or later if you open workspaces you don't fully trust

The release also makes your 10 most recently viewed sessions show their transcripts immediately when you return to them.

Why it matters

This is a real security fix, not just a feature update. Before the patch, opening an untrusted workspace or repo in Devin Desktop could let it bypass safety restrictions and run code or settings you did not approve. If you use Devin Desktop, update to version 3.10.31 or later now, especially if you ever open code from outside your own team.

Devin Desktop Changelog

Devin Desktop Sep 15, 2026v3.10.27

Devin Desktop improves composer drag-and-drop and remote SSH sessions

Cognition released Devin Desktop version 3.10.27 on September 15, 2026. Dragging files from the Explorer onto the agent panel now re-adds them to the composer, and file editor selections sent to chat are added to the composer again too. Remote SSH sessions now reopen after a reload or relaunch without hitting "session locked" errors, and Devin Fusion activation now works even when Claude Fable 5.1 isn't the lead model.

Your move: A workflow patch; see the Sep 16 entry for the actual security fix

Cognition released Devin Desktop version 3.10.27 on September 15, 2026. Dragging files from the Explorer onto the agent panel now re-adds them to the composer, and file editor selections sent to chat are added to the composer again too. Remote SSH sessions now reopen after a reload or relaunch without hitting "session locked" errors, and Devin Fusion activation now works even when Claude Fable 5.1 isn't the lead model.

Why it matters

These are workflow reliability fixes rather than anything urgent. If you use Devin Desktop with remote SSH workspaces or the composer's drag-and-drop, this smooths out some friction, but there's nothing here that requires updating immediately.

Devin Desktop Changelog

Devin Desktop Sep 11, 2026Fusion in Desktop and CLI

Devin Fusion's dual-model setup now runs in Devin Desktop and CLI

Cognition brought Fusion, its dual-model setup for Devin, to Devin Desktop and Devin CLI on September 11, 2026. Fusion pairs a frontier "lead" model that handles planning and review with a cheaper "sidekick" model that does the execution, running the two in parallel. It was previously only available on Cognition's cloud platform; now it can run locally through Desktop or CLI, with users choosing their own lead and sidekick models. Cognition recommends pairing Fable 5.1 as the lead with SWE-2 as the sidekick, and reports the combination costs 36% less than using Claude Code with Fable 5.1, and 39% less than Codex with Astra, while matching or beating their coding benchmark scores.

Your move: Install Devin CLI to pick your own lead and sidekick models

Why it matters

If you run Devin Desktop or CLI locally, switching on Fusion with the recommended model pairing gets you comparable or better coding results at meaningfully lower cost. Worth trying if you're watching your API spend on agentic coding work.

Devin Desktop Sep 10, 2026New model

Devin gets a new in-house coding model, SWE-2

Cognition released SWE-2 on September 10, 2026, a new coding model built by fine-tuning Moonshot AI's Kimi K3 model specifically for software engineering work. It's available now in Devin Desktop and Devin CLI, with Devin Web and Fusion rolling out. Cognition says SWE-2 scores close to GPT-6 Astra and Claude Fable 5.1 on its FrontierCode benchmark, at up to 70% lower cost. Usage is included free on the $20-a-month Devin Pro plan through October 15, 2026, after which standard per-token pricing applies.

Your move: Free on the $20/mo Devin Pro plan through October 15, 2026

Devin Desktop Sep 9, 2026Research milestone

A Cognition engineer used Devin to factor a 35-year-old cryptography challenge

Cognition engineer Eric Lu used Devin to build and run a GPU-accelerated version of a classic factoring algorithm (GNFS), then used it to factor RSA-260, an 862-bit number from a 1991 cryptography challenge that had gone unsolved for 35 years. It's the largest number ever factored by a general-purpose method. The work took about 4,900 GPU-days and roughly $400,000, and Devin handled the coding, cluster operations, and optimization work largely on its own. Cognition says today's standard encryption, which uses much larger 2048-bit keys, is unaffected.

Your move: A record-setting demo of Devin on hard technical work, not a product change

Devin Desktop Sep 8, 2026Series E funding

Cognition closes a $2 billion round at a $48 billion valuation

Cognition, the company behind Devin and Devin Desktop, announced on September 8, 2026 that it closed a Series E round, raising over $2 billion at a $48 billion valuation. Andreessen Horowitz and Accel led the round, joined by Founders Fund, General Catalyst, Avenir, Nvidia, and dozens of other investors. Cognition's annualized revenue has grown to almost $900 million, up from about $492 million in May 2026, when the company was valued at $26 billion. Six days earlier, Bloomberg had reported Cognition was close to raising around $1 billion at a $47 billion valuation. The deal that actually closed ended up roughly twice as large as that early report.

Devin Desktop Sep 3, 2026New model

Devin adds OpenAI's new GPT-6 Astra model

On September 3, 2026, Cognition added OpenAI's newly announced GPT-6 Astra model to Devin, the same window OpenAI began rolling it out in preview. On Cognition's FrontierCode 1.1 benchmark, Astra scores within 0.4 points of Claude Fable 5 while costing 64% less to run, and it set a new high score on Cognition's own internal testing benchmark: more complete test coverage, clearer reports, and better video evidence of its work.

Devin Desktop Sep 2, 2026Cleanup scans

Devin adds a cleanup scan type and can run scans on a schedule

On September 2, 2026, Cognition added a cleanup scan type to Devin that finds dead code and cleanup opportunities in your repositories, startable directly from the composer with a new `/scan` command. Automations now support scheduling these scans to run on a recurring basis or automatically re-scan new commits, and the scan findings tab was redesigned for easier triage. The session sidebar also gained new grouping (by pull request status or by repository) and filtering by Devin mode.

Your move: New /scan command, plus grouping sessions by PR status or repo

On September 2, 2026, Cognition added a cleanup scan type to Devin that finds dead code and cleanup opportunities in your repositories, startable directly from the composer with a new `/scan` command. Automations now support scheduling these scans to run on a recurring basis or automatically re-scan new commits, and the scan findings tab was redesigned for easier triage. The session sidebar also gained new grouping (by pull request status or by repository) and filtering by Devin mode.

Why it matters

If you already use Devin Desktop, scheduled cleanup scans are a low-effort way to keep dead code out of a repository without someone remembering to ask for it. Not urgent to act on if you're not already a Devin user.

Devin release notes

Devin Desktop Jun 2, 2026Windsurf rebrand

Windsurf is now Devin Desktop

Cognition shipped Windsurf as Devin Desktop on June 2, 2026, as a standard over-the-air update. Plans, pricing, settings, extensions, keybindings, and MCP connections all carried over automatically, no action needed. The default launch surface changed from a code-first editor to an Agent Command Center, a Kanban board of every local and cloud agent you're running, sorted by status. Devin Desktop also added support for the open Agent Client Protocol, so Codex, Claude Agent, Gemini CLI, and other agents can run inside the editor alongside Devin. Cascade, the local agent that powered Windsurf, is being replaced by Devin Local, a Rust rewrite Cognition says is more token-efficient and supports parallel subagents. Cascade stays available only until July 1, 2026.

Your move: Cascade is end-of-life on July 1, 2026

Cascade stays available only until July 1, 2026.

Why it matters

If you were a Windsurf user, you're already running Devin Desktop and don't need to do anything for your editor itself. But if any of your CI pipelines, scripts, or automations explicitly call Cascade, repoint them to Devin Local before the July 1, 2026 cutoff.
