OpenAI: o1
The OpenAI o1 is a large language model that accepts input in three modalities: text, image, and file. It has a context length of 200,000 tokens and can support tools, but its structured output capabilities are not specified. The model also supports reasoning tasks. For those who prioritize versatility and robust performance at a premium price, the OpenAI o1 may be worth considering. Its blended benchmark score of 52.4 across three independent benchmarks is respectable, even if it falls short in certain areas, as evidenced by its coverage of only three benchmarks. However, with an input cost of $15 per million tokens and an output cost of $60 per million tokens, the OpenAI o1 may be out of reach for those on a tighter budget.
