Download OpenCode 1.16.2

Core

Bugfixes
- Reasoning summaries now only run on providers that support them, avoiding GPT-5 request failures on compatible backends.
- Edit operations now refuse loose matches that could overwrite the wrong code or replace an existing file by mistake.
- Fixed Bedrock sessions hanging before a model response starts. (@alblez)

Improvements
- Diff viewer now supports next and previous hunk navigation.
- Terminal themes now refresh after live terminal reloads without stale colors or broken highlighting.
- Running subagents can now be sent to the background so you can keep working.
- Sessions now persist system context updates during long-running conversations.
- Added Snowflake Cortex provider support. (@kameshsampath)

TUI

Bugfixes
- Fixed the external editor fallback so attach-mode sessions still open when the original project path is unavailable locally. (@pcadena-lila)
- Permission replies now route through the correct session directory.
- /mo now prefers the models command in slash autocomplete.
- Fixed crashes from malformed path or diff metadata in permission and session views.

Desktop

Bugfixes
- Fixed titlebar tab overflow clipping.
- Fixed overflowed titlebar tabs so scrolling and drag regions behave correctly.
- Improved tab closing and navigation so the next tab is selected more reliably.

Improvements
- Improved multi-server desktop support with per-server home state and session tabs.
