Hello from The AI Night,
Today in AI:

Here's the deal: OpenAI released ChatGPT Health, a dedicated compartmentalized space within ChatGPT where users can connect medical records and wellness apps to get personalized health responses. The feature is currently waitlist only with plans to expand on web and iOS.
The Breakdown:
Users can connect medical records via b.well plus apps like Apple Health, MyFitnessPal, Function and Peloton
Health conversations are stored separately with purpose-built encryption and are not used to train foundation models
Over 230 million people already ask health questions on ChatGPT weekly according to OpenAI's analysis
Built with input from 260+ physicians across 60 countries who provided 600,000+ feedback instances over two years
Medical record integrations and some apps are US-only; EEA, Switzerland and UK users are currently ineligible
Evaluated using Health Bench, an internal clinical assessment framework with physician-written rubrics
The bigger picture: This positions ChatGPT as a persistent health layer rather than a one-off Q&A tool. If adoption scales it could reshape how consumers prepare for appointments and interpret personal health data.

Here's the deal: xAI has announced the completion of its Series E funding round, raising $20 billion. The round exceeded the original $15 billion target and includes strategic backing from NVIDIA and Cisco Investments
The Breakdown:
Colossus I and II data centers now run over one million H100 GPU equivalents
Grok 4 series built using reinforcement learning at "pretraining-scale compute"
Grok Voice supports real-time conversations with tool calling and is deployed in Tesla vehicles
Platform reach spans approximately 600 million monthly active users across X and Grok apps
Grok 5 is currently in training
Investors include Valor Equity Partners, Fidelity, Qatar Investment Authority, MGX and Baron Capital Group
The bigger picture: This positions xAI as one of the most heavily capitalized AI labs globally with an aggressive infrastructure lead. The combination of massive compute scale and direct distribution through X creates a distinct path to deploying frontier models at consumer scale without relying on third party platforms.

Here's the deal: Anthropic is planning a funding round that would value the Claude chatbot maker at $350 billion according to sources speaking to Reuters. Singapore sovereign wealth fund GIC and Coatue Management are expected to lead the financing.
The Breakdown:
Valuation nearly doubles from the $183 billion mark set in early September's Series F round
Round could close within weeks though size and terms may shift
Company previously raised $13 billion in that September round
Anthropic has hired law firm Wilson Sonsini to prepare for a potential IPO as early as 2026
Founded in 2021 by former OpenAI staff with Claude models gaining traction among developers for coding tasks
Reuters reported in October the company aimed to more than double its annualized revenue run rate this year
The bigger picture: This signals continued institutional confidence in frontier AI labs despite bubble concerns. For Anthropic specifically it provides a runway for compute and talent while keeping IPO optionality open
