OpenCode no longer updates itself, and /update moves you to OpenCode 2

OpenCode, the open source coding agent, stopped installing updates on its own. You run /update when you want one, and once you're current, it offers OpenCode 2.

OpenCode no longer updates itself, and /update moves you to OpenCode 2

First, how updates work now.

OpenCode used to install small updates silently at startup. Now it checks every ten minutes and puts a notice on the home screen. If you switched update checks off, they stay off.

Type /update and a dialog offers Skip or Update. The install runs in that dialog, then a Restart button finishes it. A skipped version stays quiet until a newer one ships.

Once OpenCode 1 is current, /update offers OpenCode 2, the next major release, with a warning that it has breaking changes. Dismiss it, and the offer returns in a week.

In the shell, the upgrade command takes a new major flag. It removes OpenCode 1 and installs OpenCode 2 with the same package manager. If that fails, OpenCode 1 goes back.

Next, models and providers.

Zen, OpenCode's pay per request service, adds Claude Sonnet 5.5, Claude Haiku 5.5, and Mistral Large 4 at half price. The Go plan adds Haiku, and Zen's free list gains Exo and Step 5.

If you pay OpenAI for its ultrafast service tier, OpenCode now accepts it. Before, picking that tier failed validation inside OpenCode.

On xAI, when a tool returned an image, Grok got only the words, Image read successfully. Asked about this test card, it invented a red square. Now the image itself arrives, and Grok describes the pelican card correctly.

Grok now sees the images your tools return

After

If you run Claude with thinking on through GitHub Copilot, a turn with several tool calls used to stop with an error at the second call. Now it runs to the end.

Then the fixes.

OpenCode's macOS release binaries are now signed with an Apple Developer ID, so allowlists that trust a publisher accept them. And a build you compile yourself is re-signed, so macOS 27 stops killing it.

When a client attaches to a terminal session on OpenCode's server, its origin and ticket are now checked first, before OpenCode looks up whether that terminal exists.

On Windows, the status dialog shows plugin names instead of folder paths. Model requests carry their session ID and the parent session's, so a proxy can group them. And C++ module files get highlighting.

Last, before you move to OpenCode 2.

If you installed OpenCode with Chocolatey or Scoop, the major upgrade can't move you. OpenCode 2 skips Windows package managers and offers a standalone download instead.

OpenCode 2 has three breaking changes. Plugins use a new API and need porting. Tools that call OpenCode's server need updating. Terminal settings move to one file by themselves. Your config, agents and skills keep working, and the Migrate from V1 guide covers the rest.
