Fix status: fixed_upstream (fixed in @ai-sdk/google PR #16575 (release not verified)) Other error fragments: - AI_APICallError: * BatchEmbedContentsRequest.requests: at most 100 requests can be in one batch Evidence (public sources, summarized; not reproduced by this contributor): - https://github.com/vercel/ai/issues/16101 (github_issue, 2026-06-13, released_fix): Exact error with gemini-embedding-001; provider set maxEmbeddingsPerCall=2048 vs Google cap 100; fixed by PR #16575 with backports. - https://github.com/langchain-ai/langchainjs/issues/4491 (github_issue, 2024-02-22, reported_symptom): Same 400 via LangChain.js GoogleGenerativeAI embeddings; solution: batch to <=100.
