Original GPT-5 workhorse for reasoning, coding, writing, and tool workflows
GPT-5 by openai is offered by 34 providers on this page. Public prices are shown for 30 of them. Its official list price is $1.25 per 1M input tokens and $10.00 per 1M output tokens. The lowest paid channel is Ofox at $1.00 / $8.00 per 1M, about 1.4× below the list price. That channel is a third-party gateway, so confirm its availability and rate limits before depending on it.
Artificial Analysis rates it 23 on the Intelligence Index, with 37.8 for coding. Against its lowest blended price of $2.75 per 1M, that is roughly 8 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 118 tokens per second, with 56.89s to the first token.
The context window is 400,000 tokens at the reference host, but hosts report different limits, from 128,000 to 400,000, so the usable window depends on the provider you pick. It supports reasoning, tool use, and structured output. Accepted input modalities are Text, Image, and PDF. Providers report the capability flags inconsistently, so verify a specific feature against the host you plan to use. Its training knowledge cuts off at 2024-09-30.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

The same benchmark scores very differently across harness / dataset, so the qualifying conditions must be shown together.
Individual evaluations run by Artificial Analysis, on the same reasoning tier as the intelligence score above. Each benchmark has its own task set and harness, so rows are not comparable with one another. The Intelligence Index above draws on a different, newer set of evaluations.
