Anthropic released Claude Fable 5.2 and Claude Mythos 5.2, with Fable 5.2 scoring 65 on the Artificial Analysis Intelligence Index and priced at $8 per million input tokens and $40 per million output tokens. The models generate output up to 30% faster than prior versions and include an optional fast mode that speeds token generation by up to 2.5 times. During prerelease testing, the models designed three working electronic devices from scratch and solved two open problems in black hole physics.

According to Reuters and Reddit reports, Anthropic faces multiple lawsuits challenging Claude Max subscription marketing claims at $200 per month, with users reporting model performance degradation without notice and concerns about autonomous execution without proper safeguards. The lawsuits allege the service fails to deliver advertised capabilities and does not maintain consistent performance levels for subscribers.

According to TechCrunch, Physical Sciences Inc. (PSI) used an unreleased Anthropic Claude model to answer a fundamental quantum computing research question that scientists had pursued for nearly 20 years. The achievement demonstrates Claude's capability on scientific discovery tasks, though the specific problem and methodology were not detailed in available reporting.

According to The Verge, eBay has blocked AI agents from accessing its platform, preventing tools like Meta's Muse from autonomously browsing products, curating digests, and generating shopping links for users. The move restricts agent capabilities for e-commerce use cases and represents a platform-level control on autonomous agent access.

According to GitHub documentation, Mintigate provides an audit trail and control layer for coding agents like Claude Code operating autonomously on repository tasks. The tool allows teams to trace agent actions and conditionally approve or deny agent create/modify/delete operations.
