How we price

Order

Providers are listed cheapest input rate first, then by output rate, a tie going to the creator's own listing. A provider that lists the model without a published rate sits at the end.

Prices

Base-tier, on-demand rates in USD per 1M tokens, converted at ECB reference rates where a provider publishes in another currency. Cached-input and batch rates show only where a provider publishes them. "Cheapest" marks the one provider with the lowest input and output pair; a tie wears no badge.

Cost

Input rate times the input tokens plus output rate times the output tokens, at the monthly volume set above the table. Cached-input, batch, long-context and reasoning-token billing are not modelled.

Transparency and funding

Heads up: Base-tier, on-demand rates per 1M tokens; cached, batch and long-context tiers excluded. A provider may serve a shorter context or a quantized build than the creator's release. Verify before provisioning. More on how we price.

Common questions

What is GPT-5 good for?

Reasoning-heavy coding and agent work, in the middle of OpenAI's price range.

When is GPT-5 not a good fit?

New projects: OpenAI now calls it a previous model, recommends GPT-5.6, and plans to shut down the API model in December 2026. Closed weights, so no self-hosting.

What is the cheapest way to run GPT-5?

The cheapest hosted rate is $1.25 / $10.00 per 1M tokens via OpenAI.

How does GPT-5 compare with GPT-5.1?

OpenAI says GPT-5.1 builds on GPT-5 with a no-reasoning mode, thinking that scales with how hard the prompt is (far fewer tokens on easy inputs), more steerable tone and formatting, and named apply patch and shell tools for coding agents. Same price, 400K-token context and text and image input. GPT-5 came out 3 months earlier.

Can I self-host GPT-5?

No. OpenAI does not publish the weights; GPT-5 is available only through hosted APIs.
