METR, after months of inside access, says Anthropic is likely improving its models about twice as fast as before, though Anthropic redacted much of the evidence. AI stocks suffered their worst day since April 2025 on November 5 after Democrats' election wins, then partly recovered on November 6, and investors are reported to be pressing Anthropic for a lower IPO valuation. This edition also covers news from November 2 to 5, because no edition has been published since the morning of November 2.
