A user says GPT-5.6 is the first model since GPT-4 vs. GPT-3.5 where the jump in capability is clearly noticeable.
- The model feels more capable and more likely to simply do the requested work.
- The biggest remaining pain point is not the model itself but the harness around it, especially Codex, which still needs work.
- The poster frames the release as a meaningful dot-release step rather than a minor incremental update.
