GPT-4o

OpenAI Context window: 128,000 tokens

Prompt style

GPT-4o prompts should be adapted to its context window, instruction-following behavior, tool-use support, and safety profile. Test with your own workload before choosing it for production.

Model quirks

• GPT-4o has a 128,000 token context window in this data set.
• Prompt behavior should be tested against OpenAI's current documentation.
• Safety, formatting, and tool-use behavior may change across model versions.

Best practices

• Run a small benchmark on your real prompts before adopting the model.
• Track quality, latency, and token cost together.
• Keep model-specific prompt adaptations documented.
• Verify structured output and tool-call behavior with automated tests.
