Anthropic announced GA of Claude Platform on AWS. Full Claude API through IAM, invoice in the AWS console, identical pricing. Skills, Managed Agents, Advisor pattern and MCP connector – all the same day, no weeks of waiting like with Bedrock. What it actually unlocks for a dev and the team.

Meta Ads AI Connectors in open beta. Official MCP server and CLI, 29 tools with read+write access to your ad account. Claude and ChatGPT can pause campaigns, adjust budgets, and write ad copy. What it does, what it doesn't, and why it's the biggest Meta ecosystem story this year.
