The list of premium LLM models shown under the Team Ultimate subscription on the billing page appears to be outdated, as seen in the image below. Claude 3.5 Sonnet no longer seems to be available — at least not under the Individual Ultimate subscription — and some of the other models listed might not be as relevant as some newer models.

The models in the list should only show available models, like Claude 4 Sonnet instead of Claude 3.5 Sonnet, and probably more recent ones like Gemini 2.5 Pro Preview, DeepSeek R1, o4 mini, o3, etc.
