Anthropic AI Updates: September 4, 2026

1. Anthropic Signs a $35 Billion Cloud Deal With Lambda

Anthropic. The agreement covers a roughly 350 megawatt data center in Nueces County, Texas, developed by former crypto miner Hut 8, with NVIDIA holding the lease and Lambda supplying compute to Anthropic. Hut 8 had disclosed a 15-year lease with an unnamed client in July 2026, now revealed as this arrangement. The Lambda contract is separate from the $45 billion Nscale deal for a West Virginia facility announced a week earlier, and lands ahead of Anthropic’s planned IPO as demand for Claude and Claude Code continues to grow.

2. Claude Code v2.1.260 Adds a Side-by-Side Diff Panel and Prompt-Cache Diagnostics

Anthropic. The release adds a diff panel that opens beside the conversation in fullscreen mode and shows uncommitted changes as Claude edits, toggled with /diff. /cost and the status line’s prompt_cache field now report a likely cause for cache misses, such as changed tool definitions or system prompt, or idling past the TTL. Headless sessions gain /reload-plugins so it appears in Claude Code Desktop and SDK command lists, plus a text form of /advisor for the desktop app, Remote Control, and -p and Agent SDK sessions. The Claude apps gateway adds oidc.scope_on_refresh for IdPs that only return an id_token on refresh when openid is requested again, and support for newer Claude Desktop policy keys including userPluginMarketplacesEnabled and userPluginUploadsEnabled.
