   Cognition Adds Gemini 4 Carbon to Devin, Reports Higher Coding Scores

   Cognition's AI development tool Devin now lets users run Gemini 4 Carbon in the Devin Desktop app and Devin CLI, a command-line tool. The company says the model scored higher than its predecessor on its own test of real engineering tasks.

   • Gemini 4 Carbon scored 40.0% on the FrontierCode 2.0 test.
   • That is well above the 26.3% of its predecessor, Gemini 4 Argon.
   • It also edges out GPT-6.1 Sol's 39.0% on the same test.
   • At low reasoning effort, it already beats Argon's best score.

   Claude Fable 5.2 Arrives in Devin, Tops Real-World Coding Benchmark

   Claude Fable 5.2 is now available in Devin, an AI developer tool. It scored 49.1% on FrontierCode 2.0, a test of real engineering work, taking the top spot.

   • FrontierCode 2.0 measures code quality and whether changes can be merged into real projects.
   • Fable 5.2 improved strongly over Fable 5.1's 32.4% and beat Opus 5.5's 45.5%.
   • At low reasoning effort (how much effort the AI spends on an answer), Fable 5.2 already beat Fable 5.1's best score, at less than a third of the cost per task.

   Cognition Cuts Devin Review Cost 82% With Version 2.0

   Cognition has launched Devin Review 2.0, an AI code review tool. Since August, the cost of reviewing a pull request has dropped 82%, so it is now cheap enough to run on every one. Repeat reviews now check only the changed parts, lowering costs further.

   • A typical review now costs about $0.25 to $0.75.
   • Bugs found per pull request rose from 1.22 to 1.32.
   • Review speed improved 1.5 times, with median response time falling from 139 to 94 seconds.
   • Users can start a review on GitHub or GitLab with a '/devin review' comment.

   Devin adds hierarchical budgets to manage AI spend along company lines

   Devin, the AI software engineer, launched hierarchical budgets that let enterprises manage AI spending to match how they are organized. Admins give ACU budgets (Devin's unit of usage) to department leaders, who then set and approve usage limits for their sub-teams.

   • Child budgets can sit under the company-wide budget, up to three levels deep.
   • Each budget can have its own monthly limit, a temporary bump for the current monthly cycle, and per-user limits.
   • Department heads see and manage only their own budgets, and requests for higher limits go to them.
   • Setting aside a dedicated budget for a project such as security hardening lets companies track that spending separately.

   Devin Security 2.0 launches, built for a new security threat landscape

   Devin released Devin Security 2.0, a security tool that scans code with frontier AI models to find vulnerabilities (security weaknesses), ranks them by real risk in your environment, and drafts code change requests to fix them.

   • It can scan with frontier security models such as Claude Mythos, and companies do not need separate access to those models.
   • It uses an approach called Agentic MapReduce, splitting code into batches investigated in parallel and then combining results to keep costs down.
   • Important findings are checked in an isolated environment against a running instance of the app.
   • It targets a world where AI is speeding up attacks, as with the recently disclosed remote code execution flaws (attacks that run commands on a server from outside) in PHP and Node.js.

   Devin launches three enterprise features to allocate AI spend by efficiency

   Devin introduced three new enterprise cost-control features. Instead of putting the same usage cap on everyone, they allocate spending based on how efficiently each engineer uses Devin and tell less efficient users what to fix.

   • Efficiency Score gives each engineer a 0 to 100 rating based on recent Devin use.
   • Devin Coach flags mistakes such as vague requests or picking an expensive mode for a simple task before a prompt runs, and suggests fixes.
   • Engineers with good efficiency grades get their limits raised automatically as they near them, up to a ceiling the admin sets.
   • The score also credits investigation and planning work that leaves no PR (a code change request) by estimating the hours a human would have needed.

   Devin Oncall launches to investigate and fix production incidents

   Devin made Devin Oncall, a tool that helps handle service outages, generally available. It investigates alerts and bug reports on its own to find root causes and helps teams diagnose and resolve problems in live services.

   • On SREGym, a benchmark built from real incidents, it achieved a 100% success rate with the fastest time to mitigation.
   • At Reducto, it caught warning signs and opened an incident before the company's own alerts fired, greatly reducing the impact.
   • At AngelList, it found the right root cause 3.5 times more often than the in-house tool and handled half of incidents end to end.
   • Some of the world's biggest companies now rely on it for thousands of live alerts each day.

   Gemini 4 Argon arrives in Devin at 75% off through October 27

   Google's new Gemini 4 Argon model is now in Devin Desktop and the Devin CLI (command-line tool). Until October 27, it can be used at 75% below list price.

   • The price combines Google's 50% launch discount, running through December 1, with an extra 50% off in Devin through October 27.
   • On Devin's in-house coding benchmark FrontierCode 1.1, it scored 60.5%, edging past GPT-6.1 Sol (60.4%) and on par with GPT-6 Sol (60.7%).
   • It is the highest-scoring Gemini model on that leaderboard, four points ahead of Gemini 3.7 Flash.
   • It reads widely and reviews its own changes before finishing, and is strongest at bug fixes and refactoring (restructuring code) in backend and systems code.

   Devin launches Pylon integration to speed up fixes for customer issues

   Devin can now connect directly to the customer support tool Pylon. Support teams can hand investigations to Devin from Pylon, and engineers can pick up the first round of work Devin has already done.

   • When a ticket is flagged for engineering, Devin checks logs, reproduces the bug, finds the root cause and opens a fix PR (a code change request).
   • Progress syncs automatically in both directions between Pylon and Devin, so no one has to pass updates along by hand.
   • Beyond bugs, it can search the codebase to answer product questions and create screenshots and demo videos.
   • Devin is offering $15,000 in credits to new customers who use Pylon.

    Claude Haiku 5.5 comes to Devin, beating Sonnet 5 at about an eighth of the cost

    Claude Haiku 5.5 is now available in Devin. It outscored Sonnet 5 on Devin's in-house coding benchmark while costing about one-eighth as much per task.

    • It scored 58.4% on Devin's FrontierCode 1.1 benchmark, ahead of Sonnet 5.
    • It joins the helper (sidekick) models in Devin Fusion, which pairs a lead model with a helper model.
    • With Haiku 5.5 as the helper, Fusion keeps a top-tier score of 66.2 while cutting cost and delay.
    • Users can try it now in the Devin CLI (command-line tool) with Opus 5.5 as the lead model.
