Well this was a fun* way to spend half a vacation day - AWS suddenly blocked and 12 hours later unblocked the use of Haiku in my AWS News account. I scrambled to deploy a fallback to the native Anthropic API, and JUST as I deployed the fix, they recovered. Oh well, at least I have a fallback now.

This is great! DynamoDB now has full native support for vector search. I’m still holding out for vector support in DSQL though, so I can finally drop Aurora Serverless. aws-news.com/article/2026...

I hate that this announcement doesn’t mention any prices or even if it’s an INCREASE OR DECREASE in price. (It’s an 80% decrease for Luna and a 20% decrease for Terra).

Claude Opus 5 is now on AWS Bedrock! It promises almost the same capabilities as Fable 5, but at half the price. And big plus: contrary to Fable, Opus supports Zero-Data Retention! aws-news.com/article/2026...

I replaced my GitHub runners with Lambda MicroVMs, and maybe you should too - new blog post on the Lambda MicroVMs released last week. They're really great! In the article and corresponding GitHub repo I outline the good, the bad, and the how-to use of MicroVMs as GitHub runners. Links below 👇

Claude's new model, Fable 5, is now on Amazon Bedrock. It is the same model as Mythos, but with additional safeguards in place. It's twice as expensive as Opus, at $10.00 per million input tokens and $50.00 per million output tokens 💸 aws-news.com/article/2026...

Have you seen the new popup to go ad-free on The AWS News Feed? Probably not, because I only show it once you've been active on the site for a while (2.2% of all cases). I haven't got many members yet, but 15% of people who saw the popup (17/109) clicked maybe later, which is a very good stat!

Did you see the new Ad-Free option in the AWS News Weekly Digest? It's a great way to support the feed and get a better experience in one go! Your membership keeps the feed alive and funds its development. Go check it out in the email or on the site!

I was wrong. GPT-5.5 on Bedrock (left) is even more expensive than on Github (right).

I will give a PostNL-internal workshop "how to build your first AI agent" soon. The participants will learn about interacting with local data and external systems through tools and an agentic loop. To get them started quickly, I built a simple interface and display to interface with. Pretty nice!

Anthropic has signed a deal to use "all of the compute capacity at [the SpaceX / xAI] Colossus 1 data center" which allows them to immediately raise session limits by 2x. Awesome news for Claude Code users, who have been in a serious compute crunch the past few weeks. buff.ly/86JDZSB

Dear diary, today I found my AWS News Frontend repo was missing push restrictions on the main branch. How did I found out? Because Claude Code committed straight to main, triggering an untested production deployment. In other news, The AWS News Feed now has infinite scroll. Oh well.
