Antigravity just updated its legacy 4.6 Sonnet and Opus engines, replacing them with brand-new releases: Claude Opus 5.5 and Claude Sonnet 5.5.

If you do not have access to Claude Code, this is a major upgrade. You no longer need separate subscriptions, terminal configurations, or waitlists to run these top-tier models inside your workflow.

A quick heads-up on availability: access is rolling out gradually.

If you check your model selector and do not see Opus 5.5 or Sonnet 5.5 listed yet, do not worry. Account provisioning is happening in waves, so let's be patient while the rollout propagates to everyone over the coming days.

Claude Sonnet 5.5 is built for speed and high-velocity execution:

• Fast, low-latency responses for snappy development loops
• Writing frontend components, scripts, and standard backend routes
• Quick inline refactoring and generating routine unit tests

It is the best default choice for day-to-day coding tasks.

Claude Opus 5.5 is designed for deep reasoning and system-level problems:

• Multi-file codebase refactors and database schema migrations
• System architecture planning and API contract design
• Tracing complex, hard-to-find runtime bugs and algorithmic edge cases

Whenever a task demands sustained reasoning that smaller models struggle with, switch to Opus.

A practical hybrid setup to balance speed and power:

• Start with Opus to define your project architecture and data contracts.
• Switch to Sonnet to rapidly write the actual components and endpoints.
• Bring Opus back in for a final security, logic, and performance review.

Check your Antigravity workspace to see if the update has hit your account yet.
