It does give an impression of diminishing returns on this family of models. The output presented in samples and quoted in benchmarks is very impressive, but compared with 4o it seems to be an incremental update with no new capabilites of note. This does, however, come at a massive increase in cost (both in terms of compute, but also monetary). Also, this update did not benefit from being launched in the wake of Claude 3.7 and DeepSeek, which both had more headlining improvements compared with what we got yesterday from OpenAI
