Slow startup time in recent OpenCode versions on Mac #46976
Description
Description
OpenCode has become noticeably slow to start over the last couple of weeks.
Environment
- MacBook with M5 chip
- Only one MCP server configured: Chrome DevTools
- No additional plugins
Issue
Startup now takes around 5–20 seconds.
Current version: 1.18.25
I don't remember the exact OpenCode version where this started, but the issue appeared roughly two weeks ago and has persisted across the recent versions.
Given the minimal setup, I don't expect MCP or plugins to be causing this delay.
Would appreciate help identifying what might be slowing down the startup.

I saw this when a model I defined in opencode.json stopped being available. I thought it was the recent Opencode update but turns out I had my ollama instance down.

Thanks for the report! OpenCode 2.0 is now out and development is focused on V2, so we're closing issues filed against OpenCode 1. Please upgrade (
opencode upgrade --major, details: https://anoma.ly/notes/opencode-2-0), and if this is still relevant on 2.0, reopen this issue or open a new one with your 2.0 version.— from 𝕺𝖕𝖊𝖓𝕮𝖔𝖉𝖊
