AI Round-up: April 25, 2026

Google's reported plan to invest up to $40bn in Anthropic set the agenda, with Reuters and CNBC coverage echoed by Reddit discussion around valuation, compute and strategic dependence. Anthropic also had a busy day beyond the financing story: its NEC partnership, election-safeguards update and Project Deal research gave the snapshot a strong Claude, enterprise and governance centre of gravity.

OpenAI's side of the day was about product and deployment: Privacy Filter, GPT-5.5 availability in the API, GitHub Copilot rollout, Perplexity access and Codex chatter all appeared across official X posts, YouTube reaction and Reddit testing. Elsewhere, Together pushed DeepSeek V4 Pro, Replit leaned into app security, Runway opened an AI show pitch contest, and news coverage kept attention on xAI's Colorado tech-law challenge and AI-related China warnings.
