  • This seems to be a smoking gun:

    Researchers say the most convincing evidence came from measuring how the cell expanded during charging.

    When a battery charges, ions move into the anode, causing it to expand. Graphite anodes have a unique expansion pattern because of changes in graphite’s layered structure. The Donut Lab cell showed this exact pattern.

    This finding matters because sodium ions are too big to fit into graphite the way lithium ions do. According to investigators, the graphite expansion pattern clearly shows that lithium is the active ion in the battery.


















  • Lying requires intent. Currently popular LLMs build responses one token at a time—when it starts writing a sentence, it doesn’t know how it will end, and therefore can’t have an opinion about the truth value of it. (I’d go further and claim it can’t really “have an opinion” about anything, but even if it can, it can neither lie nor tell the truth on purpose.) It can consider its own output (and therefore potentially have an opinion about whether it is true or false) only after it has been generated, when generating the next token.

    “Admitting” that it’s lying only proves that it has been exposed to “admission” as a pattern in its training data.
