Comparison FAQ

How to use this decision page

Is this mainly a writing comparison or a research comparison?

It is both. The useful decision hinges on whether the route is more sensitive to provider fit, writing preference, cost, or long-context analysis.

Should I compare these to OpenAI too?

Yes, if you are still provider-agnostic. This page is useful once you know you want a non-OpenAI option and need to narrow the field.
