Flagship OpenAI models:
- words (e.g. thinking, codex, mini, max, pro, etc.) don’t count unless the abbreviation is what becomes synonymous with the model (e.g. no one calls 4o, 4 Omni)
- the motivation for this market is seeing OpenAI 4 models based on GPT-5 and I’m wondering if they’ll release 5.4 all the way up to 5.9 where their increments are now by 0.1 every month or two
- instead of sticking with a model for a year and adding checkpoints every few months
- for example can we expect
