Horizon 1000: Advancing AI for primary healthcare

OpenAI

OpenAI and the Gates Foundation launch Horizon 1000, a $50M pilot advancing AI capabilities for healthcare in Africa. The initiative aims to reach 1,000 clinics by 2028.

Our approach to age prediction

OpenAI

ChatGPT is rolling out age prediction to estimate if accounts are under or over 18, applying safeguards for teens and refining accuracy over time.

In an effort to protect young users, ChatGPT will now predict how old you are

TechCrunch AI

The feature is designed to stop problematic content from being delivered to users under the age of 18.

Humans&, a ‘human-centric’ AI startup founded by Anthropic, xAI, Google alums, raised $480M seed round

TechCrunch AI

Humans&, a startup that believes AI should empower people, not replace them, has reportedly raised a $480 million seed round at a $4.48 billion valuation.

Indian vibe-coding startup Emergent triples valuation to $300M with $70M fundraise

TechCrunch AI

The funding comes as the startup claims it has scaled ARR to $50 million and is targeting $100 million by April 2026.

Deep Dive: Today’s AI Landscape

Synthesized from multiple research sources

The search results provided focus on predictions and trends for 2026 rather than specific announcements or launches from January 21, 2026. The most recent articles in the results are from mid-January 2026 and discuss anticipated developments for the year ahead.

Key areas experts are monitoring in 2026 include:

Agentic AI and autonomous systems — The focus is shifting from larger models to more intelligent, collaborative systems with improved memory and context windows that can handle complex, multi-step workflows autonomously[1]. AI systems will increasingly feature self-verification capabilities, allowing them to correct mistakes without constant human oversight[1].
