Hey, with the o1-mini model, you get 10 free requests per day, after which the requests are processed more slowly. The o1-preview model, however, doesn’t offer free requests and costs $0.40 per request. These models operate on a principle resembling “thinking”, which may cause some delays in their responses. As for the Claude 3.5 Sonnet model, it performs on par with the o1 model, at least according to benchmark tests.
