o3 has a 200,000-token context window. This is the model’s capacity for the text it considers in a request, including prompts and conversation context. Tokens are pieces of text, rather than a word or page count. The amount of context sent by your workspace can be lower.

The catalogue sets a maximum output of 100,000 tokens for o3. This is the response budget, distinct from its context window. Responses can be shorter depending on your request and the limits applied by your workspace.

o3 is listed as a reasoning-capable model. Its configured reasoning levels are low, medium, high. The default level is medium. Available controls depend on your workspace.
