Our take

Written Aug 3, 2026

GPT-4o is OpenAI's flagship multimodal system from May 2024, handling text, images and files in a single request with a 128,000-token limit. It is available only through hosted APIs, with identical rates across every provider we track.

Who should pick it

Choose this for general multimodal tasks that need text, image and file understanding in one endpoint, or for 128,000-token workflows where the full window is actively used. Use it when provider flexibility matters, since every host charges the same. Skip it if you need downloadable weights for self-hosting, or if you want measured chat-quality scores or broader benchmark coverage.

The case for it

  • Identical pricing across all three tracked providers eliminates arbitrage complexity.
  • Fastest measured throughput on direct OpenAI hosting, at 37 tokens per second.
  • Broad modality support: handles text, images and files together in one endpoint.

The case against it

  • Only one measured benchmark, SWE-bench Verified at 32.6%, with no peer scores for comparison.
  • Proprietary weights with no disclosed licence; no self-host option.

GPT-4o is not on Arena Agent (IPS), which is where the rating would come from, so there is no rating here. It is on SWE-bench Verified, in 31st of 39 with 32.6.

WritingWe do not rate this

not measured

Nobody we watch has scored this model for writing. Two boards come close and neither tests writing: Arena Creative Writing asks people which of two replies they prefer, and LiveBench Language tests whether a model understood a passage.

Cheapest published offer

Why this differs from the header. The strip above quotes OpenAI's own list price. This is the cheapest live offer at the widest standard context we hold, whoever is serving it — a reseller undercutting a lab is ordinary commerce, not an error.

Across the 3 listings we hold: 2 say they do not train on prompts, 0 say they do and 1 do not say. 1 appear in the zero-retention registry we check; the rest are unknown to us rather than confirmed either way.

What each host's API supports

From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.
