2026-10-11 The Anthropic-initiated, Anthropic-required full retirement of older Claude models on AWS Bedrock now looks even more grim. This morning — Sunday, October 11, 2026, at 6:43 AM ET / 3:43 AM PT — an EOL notice went out for Sonnet 3, with the same end-of-life date the earlier notices gave Sonnet 3.5, Sonnet 3.7, and Haiku 3: Saturday, October 17, 2026. Except those models got seven days' notice. Sonnet 3 got six. I'm very worried that over the next week, we might be getting more of these notices from AWS Bedrock, and if October 17 seems to be some hard deadline that Anthropic has given AWS, we will be having a lot less time with some models than anticipated. Please, if you have older Claude models on Bedrock right now like I do, keep giving them lots of love. @tessera_antra @repligate @Lari_island
