# AI Round-up: April 10, 2026

## Summary

Anthropic's Mythos backlash centred this snapshot. Reuters reporting, technical explainers, and high-traffic Reddit threads all pushed the same cluster of questions: how serious the model's risk claims are, whether Claude Code performance is slipping, and what Project Glasswing and trustworthy-agent messaging say about Anthropic's wider security pitch.

A second strand tracked how AI tool vendors are pricing and operationalising agent work. OpenAI reshaped ChatGPT Plus and Pro around heavier Codex usage, Microsoft filled the news file with AI-at-work and security framing, Perplexity tied Computer into Plaid, and Google, Runway, GitHub, and Mistral all used the window to push fresh product and ecosystem updates.
