Just updated codex to v0.122.0 and got a pleasant surprise!

  1. gpt-5.5 (current)        Latest frontier agentic coding model.

  2. oai-2.1                  Latest frontier agentic coding model.

  3. gpt-5.4                  Latest frontier agentic coding model.

  4. gpt-5.2-codex            Frontier agentic coding model.

  5. arcanine                 Frontier model with legendary appetite for starches

  6. glacier-alpha            intelligence that moves continents

  7. glacier-alpha-block-cy3  ice-cold intelligence

  8. glacier-alpha-block-cy4  ice-cold intelligence
I am a bit puzzled as to what these other models are for.

might as well start reading tea leaves at this point. No ones putting more gas in the tank till the market actually approaches its trillion dollar projected market cap. I wouldn't doubt if they're just finetuning existing models and promps and harnesses. Oh my.
