Leaker: Fable 5.1 AI model appears in Amazon Bedrock API routes, signaling imminent release
A well-known leaker, @synthwavedd, reported that Anthropic's Fable 5.1 AI model has appeared in Amazon Bedrock's API routing. The key change is that the model's slug now returns a 404 'Model not found' error instead of a 400 'invalid identifier' error, matching the behavior of Opus 5.1 before its release. This technical signal, combined with reports of gray-scale testing for some Claude users over the past two weeks and statements from Leo that Anthropic is accelerating release preparations, suggests the launch window is narrowing to the next few days. While the 404 error does not confirm an immediate launch, it indicates the slug is now recognized in the system, unlike a made-up identifier. The post concludes that Anthropic appears close to releasing Fable 5.1.
Fable 5.1 AI model staged on Amazon Bedrock API, signaling imminent release
A post on X reports that the AI model Fable 5.1 has been staged on the Amazon Bedrock API. The post notes that the model's API slug now returns a 404 'Model not found' error, a change from the previous 400 'The provided model identifier is invalid' error that was returned for invalid slugs like 'us.anthropic.banana'. The author states that this pattern typically occurs in the days before a model's official release, suggesting that Fable 5.1 may be launched soon. The post compares this behavior to that of Opus 5.1, which underwent a similar staging process. This development indicates that Anthropic is preparing to deploy Fable 5.1 on the Amazon Bedrock platform, a major cloud-based AI service.
