OpenAI: o1-pro
Analysis Summary
o1-pro is an early reasoning-focused model from OpenAI with vision and file input support and a 200K token context window. Independent benchmarking places its general reasoning well behind current flagship systems.
Its cost structure, with input and output pricing far above comparable models, limits it to narrow, high-value tasks where depth of reasoning outweighs cost concerns.
Most businesses will find newer, cheaper reasoning models deliver stronger results per pound spent.
