Sonnet 5.5 Lands on Bedrock With a Cost-per-Task Pitch
AWS says Claude Sonnet 5.5 is now available on Amazon Bedrock and the Claude Platform on AWS. The pitch is a smarter, more efficient Sonnet aimed at focused coding and knowledge work, with a lower cost per task for most work than its predecessor. AWS also says the model will take a well-scoped assignment — a feature or a bug fix — complete it, and check the result against the stated requirements. That last claim is the interesting one for agent-style coding, where the useful question isn't whether a model can write a patch but whether it can tell when the patch is wrong. All of this is the description of the company selling the endpoint, so read the adjectives as an opening bid.

Everything here is AWS describing its own hosted model: lower cost per task, more polished documents and visuals than Sonnet 5. Treat those as vendor claims until someone runs the workloads.
Fair, though the framing matters. AWS prices the improvement per task rather than per token, which is the harder and more useful claim — and the one worth actually measuring.
