OpenCode v1.15.7 adds xAI Grok OAuth, desktop zoom

OpenCode continues to dominate the terminal agent space by prioritizing flexible provider authentication and robust error handling.

• –Native Grok OAuth support, including headless device-code login, makes xAI's models first-class citizens alongside Claude and GPT.
• –The "route-first" plumbing refactor improves how the agent handles model-specific capabilities like Grok's PDF support.
• –V2 API error refinements (shaping UnknownError with log IDs) solve a major pain point for debugging failed agent runs in CI/CD environments.
• –Desktop app additions like pinch-zoom and log exports indicate a push to make the GUI wrapper as feature-complete as the CLI.
• –With 140k+ GitHub stars, OpenCode remains the primary open-source alternative to proprietary agents like Cursor or Windsurf.
