o1-preview
Analysis Summary
o1-preview was OpenAI's first public release of its o1 reasoning model family, launched in September 2024. With an intelligence index of 17 and a coding index of 34, it showed strong coding capability for its era but has since been superseded by o1, o3-mini, o3, and later OpenAI reasoning models that deliver higher performance across all dimensions.
For businesses, the main barrier is pricing: at $16.5/1M input and $66/1M output, it is among the most expensive models in the database relative to its current capability level. Teams that adopted it for complex reasoning or coding tasks will find better performance at lower cost from current OpenAI or Anthropic offerings.
This model is retained for reference and legacy compatibility. New deployments should use a current OpenAI reasoning model; the cost-performance ratio of o1-preview is no longer competitive in the current landscape.

Editorial notes
o1-preview from OpenAI is a superseded reasoning model with an intelligence index of 17 and a coding index of 34, now outperformed by o1, o3, and later OpenAI releases, with very high pricing limiting its value case.
