Our notes
When we would choose it
GPT-4o mini is a compact, low-cost model that has powered a great many simple automations. At the time of review it is still available, with no deprecation notice of its own, and it supports images, tool calling and structured outputs with a 128K token context window.
It remains a reasonable choice for systems that already use it and work well. For new projects, we would test GPT-6 Luna first, since it is the current low-cost model in OpenAI's newest family and has a much larger context window.
Low-cost models are ideal for the high-volume parts of a workflow, such as tagging messages or extracting a few fields. The trick is to measure where they fail and send those cases elsewhere. A simple confidence check, or a rule that sends certain categories to a larger model, often gives most of the savings with little loss in quality.
If you depend on GPT-4o mini today, keep an eye on the OpenAI deprecations page. Older GPT-4o snapshots are already being shut down, and a planned test of a replacement is much easier than a forced one. See LLM integration.

- Structured output Structured output is when an AI model returns its answer in a fixed format, such as JSON matching a schema, so software can use it reliably.
- Natural language processing Natural language processing is the field of AI that deals with understanding and generating human language, in text or speech.
- Artificial intelligence Artificial intelligence is the broad field of building software that performs tasks that normally need human judgment, such as understanding language or images.
- Fine-tuning Fine-tuning is further training an existing AI model on your own examples so it learns a specific style, format or task.
