OpenAI: GPT-4o (2024-05-13)

GPT-4o (2024-05-13) is OpenAI's multimodal release, accepting text, images, and files as input within a 128,000-token context window. It supports tool use, which makes it usable in agentic pipelines, but it does not include a built-in reasoning mode. Maximum output is capped at 4,096 tokens per completion, so tasks requiring very long generated responses will hit that ceiling quickly. At $5.00 per million input tokens and $15.00 per million output tokens, it sits in the mid-to-upper pricing tier among comparable models. Its blended benchmark score of 20.4 covers only 2 benchmarks, including a coding-specific result of 40.0, so its measured performance profile is narrow and should be treated as preliminary rather than comprehensive. Teams doing multimodal work with tool integrations may find it a practical shortlist candidate, but buyers prioritizing cost efficiency or well-validated benchmark coverage should compare it carefully against alternatives before committing.
