Email Parser currently supports the following OpenAI models for the Call OpenAI action. Each model offers a different balance of speed, capability, and cost:

• GPT-5.2 – The latest flagship model. Best for complex analysis tasks. Slower but most accurate.
• GPT-5 Nano – Ultra-fast and very cost-effective. Good for simpler tasks.
• GPT-4.1 – High-quality text understanding. Well-suited for complex analysis tasks.
• GPT-4.1 Nano – Less accurate but ultra-fast and cost-effective. Best for simple, repetitive tasks.
• o4-mini – A reasoning model capable of handling complex multi-step tasks. A solid balanced option for accuracy and cost.

New models may be added in the future as OpenAI continues to release updates. You can select the model you want to use directly in the action configuration panel, as shown below:
