What Anthropic changed, dated, with the source
- 3 November 2026Notable
Since 3 November 2026, text generated by Claude Mythos 5, Claude Opus 4.7 and Claude Sonnet 4.6 carries Anthropic's text watermark on the platforms Anthropic lists; on Sonnet 4.6 a request that sets temperature, top_p or top_k to a non-default value might not carry it. The Decoder reported on 4 November that a notice to API customers extends the watermark to Claude Opus 4.6, Opus 4.5, Sonnet 4.5 and Haiku 4.5 from 16 November 2026, a few days later on Amazon Bedrock, with the same caveat, and that customers cannot turn it off.
- 3 November 2026Minor
The pricing page lists a new Ultra plan at $200 a month and Max at $100 a month only; on 23 October 2026 it listed Max in two tiers, the higher one priced only on a help page. The usage-limits page says verified Ultra accounts have no five-hour session limit. Neither page dates the change.
