So at this point OpenAI has 6 reasoning models, 4 flagship chat models, and 7 cost optimized models. So that's 17 models in total and that's not even counting their older models and more specialized ones. Compare this with Anthropic that has 7 models in total and 2 main ones that they promote.

This is just getting to be a bit much, seems like they are trying to cover for the fact that they haven't actually done much. All these models feel like they took the exact same base model, tweaked a few things and released it as an entirely new model rather than updating the existing ones. In fact based on some of the other comments here it sounds like these are just updates to their existing model, but they release them as new models to create more media buzz.

OpenAI's progress lately:

  2024 December - first reasoning model (official release)

  2025 February - deep search

  2025 March - true multi-modal image generation

  2025 April - reasoning model with tools
I'm not sure why people say they haven't done much. We couldn't even dream of stuff like this five years ago, and now releasing groundbreaking/novel features every month is considered "meh"... I think we're spoiled and can't appreciate anything anymore :)
