OpenAI released the GPT-5.2 Thinking model today and, interestingly, in their blog post they mentioned the model excels at Excel tasks, PPT generation, and working with 3D elements.

OpenAI also included a short prompt to generate an Ocean Wave Simulation, along with the result. Here, I run the same prompt across three models — and GPT-5.2 didn’t fare well.

Models tested

  1. GPT-5.2 itself (via Cursor Agent)
  2. Gemini 3.0 Pro (Beta) — enabled for Enterprise customers
  3. Gemini 3.0 Pro — enabled for the general public

Verdict

  1. Overall, Gemini 3.0 Pro (general model) did a better job: it generated the output in one shot and has 3D depth.
  2. GPT-5.2 messed up the CSS even after multiple follow-up prompts.
