OpenCode v1.17.12 Changelog

This release is all about making OpenCode more reliable, smarter, and easier to navigate. Whether you are a developer building apps, a power user running things from your computer's terminal, or just using the desktop app to chat with AI, this update smooths out the rough edges. It focuses heavily on improving how the app connects to external tools and data (using a standard called MCP, or Model Context Protocol) and polishing the visual interface so everything feels snappier and more intuitive.

What's new

• Adaptive Thinking for Claude: The Claude Sonnet 5 AI model can now automatically decide when to slow down and "think" deeply through complex questions before answering.
• "Yolo" Mode: A new setting for the terminal interface (TUI) that automatically approves permission prompts, saving you from constantly having to click "allow."
• Cost and Token Tracker: The desktop app now displays exactly how many tokens (the basic units of text AI reads and writes) and how much money you have spent during your current chat session.
• Workspace Controls: You can now manage your project files directly when starting a new chat session.
• Live Event Streaming for Developers: The software development kit (SDK) now has a live stream feature, allowing external programs to watch and react to app events as they happen.

Improvements

• Smarter Autocomplete: The desktop app now suggests files, tools, and prompt shortcuts as you type in the chat box.
• Better Default Models: OpenCode is now better at automatically picking the best lightweight AI models for quick, simple tasks.
• Polished Design: Thanks to community feedback, the app looks much cleaner with sticky headers, hover effects, draggable error windows, and a new debug bar.
• Reliable Logins: Logging into external tools (via OAuth) is more stable, keeps you logged in longer, and tells you exactly what went wrong if a login fails.

Fixes

• Frozen Terminal Tabs: Fixed a bug where background terminal tabs would freeze or resize incorrectly.
• Lost Typing Cursor: The typing cursor now correctly jumps back to the chat box when you click back into the window.
• Forgotten Settings: The app now correctly remembers your last active web link, selected project, and chosen AI model when you restart or move a session.
• Broken Developer Tools: Fixed issues where embedded AI sessions wouldn't wake up when given new prompts, and restored the ability to pause or stream developer sessions.
• Attachment Errors: Fixed an issue where the app couldn't figure out the file type (like an image or PDF) of attachments sent via web links.
