Among the listed mental-health AI companies, only Limbic uses computational neuroscience and LLMs.

Judge as of 2023-12-29. The claim says that among the mental-health AI companies Khosla listed in that post, Limbic was the only one using both computational neuroscience and LLMs. True: Limbic did use both (as shown by its publications or product documentation), and none of the other listed companies publicly used both as of late 2023. Mostly true: Limbic used both and at most one other listed company used both only marginally or ambiguously. Mixed: Limbic used both, but one or more of the other listed companies clearly also used both. Mostly false: Limbic used only one of the two, or several listed companies clearly used both. False: Limbic used neither computational neuroscience nor LLMs.

   “It uses generative AI to support patients between therapy sessions, essentially replacing PDF worksheets and workbooks with conversational AI trained on those same materials.”

E3 and E8 describe Limbic's tools as using a large language model or generative AI, but both date from after 2023-12-29; E2 and E5 describe an LLM-powered therapy tool deployed from October 2023, but the quoted text does not name Limbic. None of the evidence shows that Limbic used computational neuroscience. None of it identifies which companies Khosla listed in the post either. E1, E6 and E7 describe Tetricus Labs as using AI computational neuroscience, but they do not show that Tetricus was on Khosla's list or that it used LLMs, so the evidence cannot settle the comparison the claim depends on.
