Windsurf: Sign In With ChatGPT to Use Your Plus or Pro Plan in Devin Desktop

WindsurfView original changelog

Windsurf's Devin Desktop (v3.10.48) added Sign in with ChatGPT, letting users apply an eligible ChatGPT Plus or Pro plan to cover GPT model usage. The option works with Fusion mode, and Windsurf's documentation highlights running Fusion with GPT-6 Astra as the lead model and SWE-2 as the sidekick as the best-value setup under this billing method. The release also brings smaller performance and memory improvements.

Key Takeaways

  • Sign in with ChatGPT lets Devin Desktop users apply an eligible ChatGPT Plus or Pro plan to GPT model usage.
  • The feature is compatible with Fusion mode, so the dual-model workflow can also run on a ChatGPT subscription.
  • Windsurf's docs recommend GPT-6 Astra as lead with SWE-2 as sidekick as the best-value pairing under this billing method.
  • New diagnostic profiling commands help users analyze language server memory and CPU usage.
  • Fixes stop long shell commands from accumulating memory in the Agent window and keep all folders in multi-folder workspace sessions.
  • A smaller settings file and reduced background polling when the app is unfocused improve responsiveness for accounts with many models.

Sign in with ChatGPT

Windsurf's Devin Desktop v3.10.48 lets users authenticate with their ChatGPT credentials and put an eligible ChatGPT Plus or Pro subscription to work for GPT model usage. Instead of paying separately for GPT model access inside Devin Desktop, developers who already subscribe to ChatGPT can reuse that plan, which can meaningfully lower the cost of running OpenAI models in their daily workflow.

The feature also works with Fusion mode, Devin's dual-model setup that pairs a lead model with a sidekick. Windsurf's documentation specifically points to Fusion with GPT-6 Astra as the lead and SWE-2 as the sidekick as the option that offers the best value when billed through a ChatGPT plan. That pairing lets the stronger GPT model handle planning and hard reasoning while the faster SWE-2 model takes on the bulk of the execution work.

Devin Desktop Improvements

Beyond the sign-in option, the release includes several quality-of-life fixes that regular users are likely to notice.

Diagnostics and memory

Windsurf added diagnostic profiling commands for analyzing language server memory and CPU usage, which makes it easier to track down slowdowns. Long-running shell commands no longer pile up in the Agent window's memory, keeping the app lighter over extended sessions.

Workspaces and settings

Multi-folder workspace sessions now keep all folders when a session starts without an explicit folder selection, rather than dropping some of them. The settings file is also smaller for accounts with many available models, which removes stalls that previously appeared while typing or copying text.

Background behavior

Background session polling now scales back when the application loses focus, reducing unnecessary activity when Devin Desktop is not in the foreground.

Why It Matters

Bring-your-own-subscription billing is becoming a common way for AI coding tools to reduce friction and cost for developers. By letting ChatGPT Plus and Pro subscribers use their existing plan, Windsurf makes GPT models in Devin Desktop more accessible, and the Fusion recommendation gives users a clear, cost-conscious default configuration to start from.
