ChatGPT's paradox of choice - Axios

OpenAI announced the release of three new GPT-5.6 models—named Sol, Terra, and Luna—alongside the introduction of ChatGPT Work, an agent designed for multi-step tasks. The updates are integrated into a unified ChatGPT application. The company described the release as a significant step in expanding the capabilities of its conversational AI platform.

According to the article, the three models offer different performance characteristics, though OpenAI has not publicly specified the distinctions between Sol, Terra, and Luna. ChatGPT Work is intended to handle complex, sequential instructions, such as multi-step data processing or document generation. The models are part of the GPT-5.6 iteration, a mid-cycle upgrade from the previous GPT-5.0.

Axios notes that the multiple model release creates a 'paradox of choice' for users, who must manually select which model to use for each query. While the unified app aims to streamline access, the necessity to choose among three options may lead to user confusion. The article suggests that the naming convention and the multiplicity of models could complicate the user experience, despite the technological advancements.
