Best n8n openai workflows.

OpenAI is the most-used integration in the catalog by a wide margin. These are the highest-quality patterns: agent loops, structured-output extractors, embedding pipelines, image generators, transcription flows.

When to use these
Any LLM-backed automation — chat, classification, extraction, summarisation, embedding generation.
Skip these if
You're cost-sensitive at scale — consider llmChat with self-hosted Llama/Mistral instead.

What makes a workflow rank in this list

The QualityScore is calibrated against a hand-rated ground truth of 20 workflows (Spearman ρ = +0.941). Workflows score higher when they have: clean graph topology (no spaghetti), explicit error branches, sticky-note documentation, complete parameter coverage, and rich metadata (description, integrations, credentials). See the methodology page for the full axis breakdown.
