Our take
Written Aug 3, 2026GPT-4o is a proprietary multimodal model from OpenAI that handles text, images and files in a single request. It offers measured coding capability and consistent pricing across its two listed providers, making it a predictable choice for teams already in the OpenAI ecosystem.
Pick this when you need a multimodal workflow with text, image and file inputs, or when you want verified coding performance with a single benchmark to point to. Use it if provider simplicity matters: both hosts charge the same rate, so there is no arbitrage to hunt. Skip it if you need chat-quality scores, reasoning benchmarks, or any efficiency comparison based on parameter count — none of those are available.
The case for it
- Identical pricing across both providers eliminates arbitrage complexity.
- Direct OpenAI access offers a known throughput of 80 tokens per second.
- Measured coding capability: 21.6% on SWE-bench Verified, with a clear evaluation date.
The case against it
- Only one benchmark score in our data, and it is modest: 21.6% on SWE-bench Verified with no other measured dimensions.
- Parameter count is undisclosed, so active-parameter efficiency and compute comparisons are impossible.
- No measured chat quality, reasoning or math scores to judge broader capability.

AgenticPlanning, calling tools, staying on task
GPT-4o (2024-11-20) 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 36th of 39 with 21.6.
WritingWe do not rate this
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.

Or rent it from someone else
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 2 listings we hold: 1 say they do not train on prompts, 0 say they do and 1 do not say. 0 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.
