-The o1 family of models includes the following models:
-
-* `o1`/`o1-preview`: These models are focused on advanced reasoning and solving complex problems, in particular in math and science. They respond more slowly than the `gpt-4o` model. Each member of your enterprise can make 10 requests to each of these models per day.

-The o3 family of models includes one model:
-
-* `o3-mini`: This is the next generation of reasoning models, following from `o1` and `o1-mini`. The `o3-mini` model outperforms `o1` on coding benchmarks with response times that are comparable to `o1-mini`, providing improved quality at nearly the same latency. It is best suited for code generation and small context operations. Each member of your enterprise can make 50 requests to this model every 12 hours.

+By default, {% data variables.product.prodname_copilot_chat_short %} uses OpenAI's GPT 4o large language model. This is a highly proficient model that performs well for text generation tasks, such as summarization and knowledge-based chat. The model is also capable of reasoning, solving complex math problems and coding.
+
+However, you are not limited to using this model. You can choose from a selection of other models, each with its own particular strengths. You may have a favorite model that you like to use, or you might prefer to use a particular model for inquiring about a specific subject.
