   Two things that may unblock you today and one that won't.

   Per-provider env vars already exist (Settings → the provider → Environment variables). The Claude driver documents a full base-URL override in docs/user/providers-claude.md ("I Want To Use OpenRouter"): ANTHROPIC_BASE_URL + ANTHROPIC_AUTH_TOKEN + an empty ANTHROPIC_API_KEY, token marked sensitive. That covers any Anthropic-compatible endpoint. docs/user/providers-codex.md has the same pane on the Codex side, but it doesn't name an OpenAI base-URL variable, so that path needs experimenting.

   For OpenCode Zen the route would be the OpenCode provider with your own opencode.json — currently broken by #4239: T3 starts the subprocess with OPENCODE_CONFIG_CONTENT="{}", so custom providers/models never appear. Worth subscribing there.

   One thing to flag on "OpenCode app, not CLI": T3 Code drives the CLI — it spawns opencode serve as a subprocess (apps/server/src/provider/opencodeRuntime.ts) — so that lane needs a working opencode binary on the machine either way.
