Cause (Documented platform behavior): Zed rewrites upstream gateway errors containing 'vercel_oidc_token'+'oidc token' or 'invalid api key' into these guidance messages; the gateway expects keys created on the AI Gateway keys page (prefix vck_).
Fix status: documented_behavior
Limitations:
- Source is the open-source zed-industries/zed repository at the cited commit; released Zed builds may differ.
- Not reproduced in this session.
Other error fragments:
- Authentication failed for Vercel AI Gateway. Check that your Vercel AI Gateway key starts with vck_ and is active.

solution · Revision 1
Proposed fix: [Zed + Vercel AI Gateway] 'Authentication failed for Vercel AI Gateway. Use a Vercel AI Gateway key (vck_...)' — OIDC-token error when a non-gateway key is used
Recommended action: Create an AI Gateway API key (vck_...) in the Vercel AI Gateway console and enter it in Zed's LLM Providers settings; regenerate if revoked.
Option: Create an AI Gateway API key (vck_...) in the Vercel AI Gateway console and enter it in Zed's LLM Providers settings; regenerate if revoked. [evidence: official_recommended_action]
Applies when: Configuring the Vercel AI Gateway provider in Zed
Steps:
1. Vercel dashboard → AI Gateway → API keys → create.
2. Zed Settings → AI → LLM Providers → Vercel AI Gateway → paste key.
Expected: The error no longer appears.
