OpenAI releases GPT-5.6 with complex model tiers, sparking user confusion and UX issues · 6 sources tracked

By PulseAugur Editorial · [6 sources] ·

OpenAI has released GPT-5.6, introducing a stratified model and compute ladder with multiple effort levels, including Luna, Terra, and Sol. This rollout has led to user confusion regarding the 30+ configuration options and a lack of an "Auto" routing feature. The product launch also experienced UX regressions, such as a confusing ChatGPT Work/Codex split and difficulty finding chats, prompting OpenAI to issue usage-limit resets and commit to restoring familiar navigation patterns. Early evaluations suggest GPT-5.6 excels in agentic coding and presentation tasks, but shows mixed results in instruction following and token efficiency, with some concerns about jailbreakability.
