build with the world's most frontier models in one unified workspace

changelog

What's shipped

July 2026

Agentic File Access rebuilt as a single-call pipeline

  • The model now reads, searches, and edits in one pass — no more separate call guessing the edit from a text marker.
  • Added read_file, list_directory, and search_codebase tools alongside edit proposals.
  • Fixed a crash on multi-tool-use responses.
  • Fixed a CRLF anchor mismatch that could cause edits to silently fail to apply.

July 2026

Builder Mode groundwork

  • Added git-warn-and-allow, initializing a repo if one doesn't exist before a Build runs.
  • Added a Revert button for stepping back a completed Build step.
  • Added Reprompt, Retry, Skip, Abort, and Dismiss handling for failed or rejected steps.
  • Added a run history view.
  • Built the AI planning layer that turns a description into a structured, editable step plan.

July 2026

Pricing restructured

  • Replaced the old three-tier structure with Go, Pro, and Max.
  • Pro and Max now run on a real dollar credit pool — priced 1:1 with the subscription.
  • Introduced a windowed allowance on Opus 4.6 in Pro, unrestricted in Max.

One context. Best models.
No more fragmented coding.
