Meridian[0] for Claude Code, CLIProxyAPI[1] for everything else [0] https://github.com/rynfar/meridian [1] https://github.com/router-for-me/CLIProxyAPI

FYI, you can use your Claude subscription pricing with OpenCode via Meridian[0], which also makes it easier to try out other models when they come out. You can also use your other subscriptions in OpenCode with CLIProxyAPI[1]. The switching cost was relatively high, mostly from claude code plugins but completely worth it. I'm now mostly using GLM-5.3 and Codex models via OpenCode and barely using Claude which seemed unfathomable less than two months ago.

Model: Cost, mainly. The runs went through a Claude Max subscription rather than metered API billing, and pinning an older stable snapshot kept run-to-run comparisons clean and cheap. The fixed harness payload (system prompt plus tool schemas), so the headline numbers shouldn't change too much. That said, happy to re-run the matrix on Fable and publish the diff; payload figures should barely move, tool-calling behaviour might. Gateway: Meridian (github.com/rynfar/meridian); proxy that bridges the Claude Code SDK to a standard Anthropic endpoint so a Claude Max subscription can drive OpenCode-et-al. It's the auth route for all agent traffic on the machine, not something built for the benchmark.
