Our take
Written Sep 2, 2026GPT-4o is a text-and-image model from OpenAI released in May 2024 that can handle up to 128,000 tokens in a single request. It carries broad measured coverage across six chat and task categories, with identical pricing across every provider channel.
Pick this for general multimodal work where predictable pricing matters more than hunting for the cheapest host, or for coding workflows where its measured coding score is the relevant signal. Use the direct OpenAI channel if throughput is your bottleneck. Skip it if you need to self-host, if maths-heavy tasks dominate, or if you want measured software-engineering resolution above two-fifths.
The case for it
- Broadest arena coverage for its vintage: six distinct categories measured, from coding to creative writing.
- Identical pricing across all three provider channels, so provider choice is about throughput and trust, not cost.
- Fastest measured throughput on the direct OpenAI channel, at 101 tps versus 66 tps on Azure.
The case against it
- Maths is its weakest measured category, with a gap of over 60 points against its own coding score.
- Resolves fewer than two in five software-engineering issues end-to-end on the benchmark we track.
- Proprietary weights with no self-host option; parameter count undisclosed.
How good is it?
A general chat model for everyday questions and writing, though it trails most models at coding tasks.

What each host's API supports
From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.
