Using your Opencode Go subscription in Claude Code
Hello, I’m Kristof, a human being like you, and an easy to work with, friendly guy.
I've been a programmer, a consultant, CIO in startups, head of software development in government, and built two software companies.
Some days I’m coding Golang in the guts of a system and other days I'm wearing a suit to help clients with their DevOps practices.

export ANTHROPIC_DEFAULT_OPUS_MODEL=minimax-m3
export ANTHROPIC_DEFAULT_SONNET_MODEL=minimax-m3
export ANTHROPIC_DEFAULT_HAIKU_MODEL=minimax-m3
export CLAUDE_CODE_SUBAGENT_MODEL=minimax-m3

export ANTHROPIC_API_KEY="$OPENCODE_API_KEY"
You can use only the Anthropic-compatible models:
check on OpenCode Go's website — you want the ones that have @ai-sdk/anthropic in the AI SDK PACKAGE column.
As of writing this (2026-06-14), these are the MiniMax and the Qwen models, the top ones being:
minimax-m3qwen-3.7-plusqwen-3.7-max
Don't expect Opus-level performance out of them (maybe Opus a few months ago), but I'm a firm believer that if you can work with the cheaper models, then you will definitely be able to work with the expensive ones when you have to.
Why would I want to do this? #
For example, I'm not currently a Claude subscriber – when I need their models, I use them through OpenRouter. But sometimes I'm interested in some new feature of their Claude Code harness, and this is the easiest (also, cheapest 😇) way to experiment with that.
