OpenCode

OpenCode uses one config file. You can keep OpenAI, Anthropic, and Gemini providers in the same file.

Config path:

~/.config/opencode/opencode.json

You can also use opencode.jsonc. Create the file manually if it does not exist.

opencode.json

Replace each API key placeholder with the CE API key for that provider: OpenAI, Anthropic, or Gemini.
