System capacity

Context window

The amount of input and output context a model can process in one interaction under the provider's rules.

Why it matters

Use it when

You are sizing a real workload and will test long-context quality, truncation, and cost.

The limitation

More tokens do not guarantee better retrieval, attention, or reasoning across the whole window.

Provider-catalogued context capacities for the models in this site’s dataset. New GPT-6.1 Sol / Sonnet 5.5 profiles were added October 1; older profiles retain their own verification dates. Capacity is a system limit, not a quality benchmark; the linked OpenAI documentation is an example receipt, not a source for every provider row.
