    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.

    Confirmed by provider. Claude Platform release notes, entry dated November 3, 2026, read 7 November 2026; the 16 November expansion is from The Decoder's report of 4 November 2026 of Anthropic's notice to API customers, as Anthropic's content-labeling help page would not open from here.

    The Grok product page no longer mentions memory across chats; it lists reasoning, coding, image generation and document analysis. xAI's consumer FAQ, the Grok help FAQ and the user guide do not mention memory either, so the Scorecard's docs grade for Grok on remembering across a new chat moved from yes to no.

    xAI retired the grok-imagine-image-quality API model on 2 November 2026, after a 60-day notice that began on 2 September. Requests to it, and to grok-imagine-image-pro (redirected to it in May), are now served by grok-imagine-image-2.0 at the low quality setting, which costs $0.01 per image less at every resolution: $0.04 per 1K image and $0.06 per 2K image, plus $0.01 per input image on edits. The old names keep resolving, so no code change is needed; grok-imagine-image (1.0) is not affected.
