+- `gpt-3.5-turbo` - Best for tasks that don't require reasoning, like data processing or generation.
+- `gpt-4o` - Will offer a very high level of intelligence and strong performance. Suitable for programming tasks that require reasoning about software architecture.
+- `gpt-4o-mini` - Suitable for programming tasks that involve straightforward implementations, like utility functions.
