Token counts vary by tokenizer and model; non-OpenAI counts are estimates. Cost is an estimate and provider pricing can change. See each model's source on the pricing page.

Two limits, not one

Models have both a total context limit and a separate maximum output limit. You can hit either: a prompt that fits the context can still request more output than the model will produce in one call. Check your input against the context limit and your expected answer against the output limit.

FAQ

Is the output limit the same as the context limit?

No. Many models cap output well below the full context, for example a 128K context with a 16K max output. Both limits apply to every request.
