Grok 4.5, xAI’s latest reasoning model, is now rolling out in GitHub Copilot. It is designed for fast, agentic coding and complex multi-step workflows, with a context window of up… The post Grok 4.5 is now available in GitHub Copilot appeared first on The GitHub Blog.
The Model Context Protocol (MCP) published its 2026-07-28 specification, the largest revision since launch: MCP is now stateless, with a governed extensions system and hardened authorization. Learn what changed and how to enable the new version on Amazon Bedrock AgentCore Gateway with a single UpdateGateway call.
An AI agent ingests a customer ticket, queries three internal APIs, looks up a record in a database, drafts a response, and hands it off to a human reviewer. Every individual call returns a 200.

Anthropic says Claude Mythos Preview helped derive an end-to-end key-recovery attack against HAWK-256 and a 200- to 800-fold speedup for an attack on seven-round AES-128. The HAWK attack exploits a previously unused symmetry in the lattice behind the signature scheme. Anthropic's released implementation gives an expected end-to-end runtime of about three hours and 42 minutes on a 96-core server
