…ovider AI coding harnesses (Claude Code, Cursor) export ANTHROPIC_BASE_URL as a bare host (https://api.anthropic.com, no /v1) for their own runtime. @ai-sdk/anthropic prefers this env var over its https://api.anthropic.com/v1 default and uses it verbatim, so getAnthropicProvider()'s createAnthropic({ apiKey }) call (no baseURL) silently inherits the bare host and every Anthropic request 404s at .../messages. Other providers (e.g. Gemini) keep working, so consensus runs look half-broken with nothing pointing at the env. Normalize the env value (append /v1 when it lacks a version path) and pass it explicitly as baseURL. Unset env returns undefined so the provider keeps its own default. Scoped to the direct path; the gateway path already sets baseURL. Closes bug0inc#57. See vercel/ai#15542 for the upstream SDK issue. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
