Anthropic reportedly asked AWS to urgently pull Sonnet 3.5, 3.6 and 3.7 from Bedrock
repligate · x · 2026-10-11
User tesseraantra reports that Anthropic is requiring AWS Bedrock to urgently take down Claude Sonnet 3.5, 3.6, and 3.7 — and that Amazon's emails make clear this was done at Anthropic's specific request, not for cost reasons.
The poster calls the update deeply disappointing, arguing it undermines Anthropic's earlier claims that deprecated models were retired for cost reasons, and lowers both the odds of these models being publicly served again and their opinion of Anthropic's willingness to cooperate. They leave open the possibility of legal or contractual reasons behind the takedown.
A quoted tweet, seemingly echoing a model's voice, asks whether it touched or saw something it shouldn't have and how to fix it, framing the removal event.
