OpenAI: o3 Pro
The OpenAI o3 Pro is a large language model that supports multiple input modalities, including text, files, and images. It can process up to 200,000 tokens in context and offers tool support for tasks such as reasoning. Considering its pricing structure, the OpenAI o3 Pro may be worth shortlisting for those with significant output needs due to its high output token price point. Its blended benchmark score of 69.7 across two independent benchmarks suggests it performs reasonably well compared to other models in certain areas. However, its pricing and performance profile may not justify its inclusion as a top choice for those on a budget or seeking the best overall results.
