AI Round-up: May 20, 2026

Google centred the snapshot with an I/O-heavy burst around Gemini 3.5 and Gemini Omni. Google DeepMind paired official X launches for Gemini 3.5 Flash, Gemini Omni, Gemini for Science and Antigravity with Singapore partnership news and a dense set of Co-Scientist research posts, while YouTube and Reddit picked up the same Gemini and coding-agent threads.

The rest of the day split between enterprise access, security and customer deployment. OpenAI launched a Singapore presence, pushed Guaranteed Capacity and expanded image provenance tooling; GitHub disclosed unauthorised access to internal repositories tied to a poisoned VS Code extension; Anthropic announced a KPMG-wide Claude alliance and continued its frontier-AI dialogue work; and Microsoft filled the news file with custom agents, Copilot deployments and security operations. Reddit stayed noisy around Claude support, Karpathy-to-Anthropic posts, Codex/Gemini comparisons and quota complaints.
