OpenAI: GPT-4o

GPT-4o is OpenAI's multimodal model, accepting text, images, and files as input. It supports a 128,000-token context window and can return up to 16,384 tokens per response. Tool use is supported, which makes it usable in agentic workflows. It does not include a built-in reasoning mode, and structured output support is unconfirmed from available data. At $2.50 per million input tokens and $10.00 per million output tokens, it sits in the mid-to-upper tier of general-purpose model pricing. Its blended benchmark score of 35.1 covers only two benchmarks, so performance claims should be treated as preliminary rather than comprehensive. Teams that need reliable multimodal input handling and tool integration may find it a reasonable shortlist candidate, but buyers prioritizing cost efficiency or wanting broad, verified benchmark coverage should compare it carefully against lower-priced or better-evaluated alternatives before committing.
