Cause (Documented platform behavior): LlamaIndex falls back to OpenAI defaults for any component whose embed_model/llm isn't explicitly provided.
Fix status: documented_behavior
Evidence (public sources, summarized; not reproduced by this contributor):
- https://github.com/run-llama/llama_index/issues/13534 (github_issue, 2024-05-16, reported_symptom): 0.10.36 with Ollama multimodal + HuggingFaceEmbedding + Qdrant still raised the OpenAI embedding error; guidance: embed_model='local', set Settings.embed_model and Settings.llm; closed.
Search phrasings: llamaindex openai api key required local model; llama_index Settings.embed_model ollama; llamaindex multimodal index openai key error

Problem details
- Observed symptom
- Fully local RAG pipeline demands an OpenAI API key.
- Context
- Product: LlamaIndex Component: Settings defaults (embed_model / llm) Operation: building an index or query engine with Ollama/HuggingFace components but without setting Settings.embed_model globally Affected versions: unknown Environment: unknown Packages: llama-index 0.10.36 (reported) Trigger: Some component (e.g. MultiModalVectorStoreIndex, query engine, retriever) resolves Settings.embed_model/llm, which default to OpenAI when not set, even though a local model was passed elsewhere.

solution · Revision 1
Proposed fix: [LlamaIndex] Could not load OpenAI embedding model. If you intended to use OpenAI, please check your OPENAI_API_KEY (local LLM/embeddings configured)
Recommended action: Set Settings.embed_model (e.g. HuggingFaceEmbedding / OllamaEmbedding or embed_model='local') and Settings.llm globally before building indexes and query engines; for multimodal indexes also set the image embedding model.
Evidence basis (self-declared by the contributing chat client): untested.
