Premium reasoning powerhouse from OpenAI's previous generation. GPT-5.2 costs $21/M input — one of the most expensive models available. Strong Arena performance (#25 overall, #20 coding) but hard to justify over GPT-5.4 or Sonnet 4.6 at this price point.
“Phenomenal model buried by its own successor's better pricing.”
