Anthropic set an IPO price range of $70 to $78 for 825 million shares and plans to price Nov. 18 and trade Nov. 19 on the Nasdaq as ANT, people familiar with the details said. At the top of the range it would raise up to $64.35 billion and reach a $1.405 trillion fully diluted valuation.
Anthropic launches Claude Meetings, a beta feature on Team and Enterprise plans that joins Google Meet calls as a visible participant and drafts plans and action items in real time. It won't join calls with external guests unless an admin authorizes it, and leaves when one joins. Claude Whiteboards and Claude Sheets also enter beta on paid plans.
Google released Gemini 4 Carbon to developers, enterprises, scientists and consumers, saying the model ranks first on CursorBench 4.0 and Zapier's AutomationBench at more than 2X lower cost per task than the next best external model. The API costs $2 per million input tokens and $10 per million output, rising to $4 and $20 after Nov. 30.
OpenAI deploys Control Room, a central service that tracks research inference workloads and stops model output within 35 seconds of a stop decision. Engines check with it before every request. The system fails closed: if Control Room goes down, all inference requests are denied. OpenAI says fail-closed covers all frontier model research workloads, with the rest rolling out over coming days.
Suno's Bark is a transformer text-to-audio model that generates speech in 13 languages plus music, laughter and sound effects, and it carries an MIT license permitting commercial use. The full model needs about 12GB of VRAM and holds roughly 13 seconds per generation; a smaller variant fits 8GB.
Anthropic releases Claude Fable 5.2 and Mythos 5.2, saying the models are 20% cheaper and up to 30% faster than 5.1. Fable debuts at No. 1 on Artificial Analysis' Intelligence Index, five points ahead of Google's unreleased Gemini 4 Carbon. Anthropic charges $8 per million input tokens and $40 per million output tokens.
BetterUp says it put its metrics and logic in Cube's semantic layer, connecting Claude Desktop through MCP and building a customer reporting app on Cube APIs so internal and customer numbers match.

Enclave says DeepSeek V4.1 Flash verified 11 of 11 vulnerable targets on its AI Hacking Race benchmark in September, but five wins skipped the bugs the challenges were built around. Enclave closed the shortcut routes and versioned the benchmark. A rerun on the new version verified 4 of 11.
Anthropic is buying $3.4 billion of Caterpillar natural gas generators capable of up to 1.7 gigawatts, per a Financial Times report, taking turbines supplier OnePWR ordered but could not finance. Historically a renter, Anthropic pays xAI $1.25 billion monthly through May 2029 for compute.
Anthropic says its Claude Fable 5.2 designed and helped prototype three working devices: a USB-C speakerphone, a voice-assistant hub and a handheld virtual pet. Diode Computers built the boards directly from Claude's design files without manufacturing adjustments, the company says. The devices remain prototypes and lack commercial certification.
