Public API Resources, Planning Mode, and Computer Preview Audio

#The public API now covers your whole workspace

Sessions, Projects, Sandboxes, Pull Requests, Messages, Repositories, Queues, and Organizations are now available as resources in the Tembo public API, joining Agents, Artifacts, Integrations, and MCP connections. You can script and integrate against nearly everything you can do in the product.

#Native planning mode in the composer

You can now switch the composer into planning mode directly from the slash menu. Tembo puts together a plan for you to review before it starts making changes, instead of diving straight into edits.

#Shared Codex and SuperGrok subscriptions for your whole workspace

Admins can now connect Codex and SuperGrok subscriptions at the workspace level so every member of the organization can use them, instead of everyone needing to connect their own.

#Computer Preview now streams audio

Computer Preview streams audio from the sandbox desktop, so you can hear what's playing while you watch Tembo work.

#Run agents when a GitHub release is published

Agents can now respond when a GitHub release or pre-release is published. Filter the trigger by repository to run your release follow-ups only where you need them.

#Keep projects ready for faster session starts

The "Keep project ready" setting is now available in project settings. Turn it on to keep sandboxes running and ready for new sessions, reducing startup waits. Keeping sandboxes ready incurs compute usage.

#Search and filter session logs

The logs view now brings together setup, sandbox, and agent logs, including VM output. Search for specific messages, filter by category, and download the filtered logs to investigate a session without digging through everything else.

#Everyday improvements

  • GPT-6 Astra is now available as a model option.
  • DeepSeek V4.1 Flash is now available, replacing the retiring Fireworks-hosted Kimi K2.6, Kimi K2.7 Code, DeepSeek V4 Pro 0813, and DeepSeek V4 Flash options.
  • Queued messages can now be reordered by dragging them or using the keyboard.
  • The composer now recognizes pasted Markdown code blocks and inline code.
  • The follow-up composer has more room to grow when writing longer messages.
  • Sidebar hover previews now stay open while dragging sessions.
  • The onboarding checklist now includes a step for connecting a Codex or SuperGrok subscription.

Also various bug fixes and improvements as always :)
