AI chat gains the GPT-5.6 (Sol/Terra/Luna) Codex models and retires GPT-5.4 Codex. Released Jul 10

​
New

  • AI chat adds GPT-5.6 Sol, Terra, and Luna Codex models; GPT-5.4 Codex is sunset.
  • New design-system slash commands plus an example buttons canvas.

​
Improved

  • AI chat streaming is smoother with an event-driven, frame-coalesced pump.
  • Billing retries Stripe checkout actions after a dropped connection, with no duplicate toast.
  • Per-model credit toggles now respect the master Tempo Inference switch.
  • Provider request failures show a specific error tag instead of a generic “unknown”.
  • “Publish failed” toasts now include the underlying git error.

​
Fixed

  • Canvas comments now land correctly when tapped on mobile Safari.
  • Issue boards no longer crash from a stale saved organization id.
  • Editing an issue with a malformed label id no longer crashes.
  • Moving issue groups tolerates a missing assignee or label set.
  • Canvas now renders all visible route storyboards, not just one.
  • Drawing over a text storyboard creates a sibling instead of overwriting.
  • Duplicated canvas previews keep the copy’s annotations.
  • Text being edited on canvas no longer shows an unwanted outline.
  • Doc suggestions resolve against the current document, not a stale state.
  • The “Comment resolved” toast now dismisses on its own.
  • “Session expired” only appears once connectivity is confirmed.
  • Agents view shows a loading state instead of “No agents yet” while loading.
  • Toasted background actions no longer crash the app.
  • Bug report screen recording asks for permission up front to avoid a capture leak.
  • AI can reference issues by a bare number (e.g. “932”).
This release brings the GPT-5.6 Codex family to AI chat: the Sol, Terra, and Luna variants are now available, while the older GPT-5.4 Codex model has been retired. AI chat also streams more smoothly thanks to an event-driven pump, and provider errors now report a specific cause instead of a generic “unknown” message. Canvas gets several fixes: all visible route storyboards render, drawing over a text storyboard creates a sibling rather than overwriting it, duplicated previews keep their annotations, and text being edited no longer shows a stray outline. On the design side, a new slash-command suite and an example buttons canvas make it easier to work with your design system. Issues and docs are more resilient — boards no longer crash on stale saved state or malformed label ids, group moves tolerate missing assignees or labels, and doc suggestions apply against the current document. Billing now retries Stripe checkout actions after a dropped connection without duplicate toasts, and per-model credit toggles respect the master Tempo Inference switch. Rounding things out: canvas comments work on mobile Safari, the “Comment resolved” toast auto-dismisses, “Session expired” waits for confirmed connectivity, and background actions no longer crash the app.
