Tencent releases HY-Embodied-0.5, a 2B-parameter vision-language model for robot control

Federal Reserve Chairman Jerome Powell and Treasury Secretary Scott Bessent met with major U.S. bank CEOs this week to assess cyber risks from Anthropic's newly released Mythos model. Anthropic deployed Mythos in limited capacity due to concerns that hackers could exploit its capabilities.

Microsoft has begun removing Copilot branding and buttons from Windows 11 applications including Notepad and Snipping Tool, replacing them with generic icons like a pen symbol. The underlying AI-powered features remain functional but are now labeled as "writing tools" rather than Copilot. This follows user complaints about forced Copilot integration and inconsistent experiences across apps.

Microsoft is removing Copilot buttons from Windows 11 apps including Notepad, Snipping Tool, Photos, and Widgets as part of a broader effort to reduce "unnecessary Copilot entry points." The underlying AI features remain intact, with Notepad's Copilot button replaced by a "writing tools" menu that retains the same AI-powered functionality.

Meta launched Muse Spark on April 8, 2026, a natively multimodal reasoning model with tool-use and visual chain-of-thought capabilities. Unlike Llama, it is entirely proprietary with no open weights. The model scores 52 on AI Index v4.0 and excels on health benchmarks but represents Meta's departure from its open-source identity.

OpenAI has introduced a $100 per month ChatGPT Pro plan positioned between its $20 Plus and $200 Pro tiers. The new tier offers 5x more Codex capacity than Plus and access to the same advanced tools as the $200 plan, with a limited-time promotional doubling of Codex allocation.

OpenAI has introduced a new $100 per month ChatGPT Pro subscription tier offering 5x more usage of its Codex coding tool than the $20 Plus plan. The tier directly competes with Anthropic's Claude Max subscription at the same price point and sits between the $20 Plus and $200 Pro tiers.

OpenAI announced a new $100/month Pro plan for ChatGPT, filling the pricing gap between its $20/month Plus tier and $200/month option. The plan offers 5x more Codex capacity than Plus and directly targets developers, positioning it as a competitive alternative to Anthropic's $100/month Claude offering.

GitHub has integrated Copilot directly into its security assessment tools, enabling organization admins and security managers to request real-time explanations and guided remediation steps from detected secret risks and code vulnerabilities without leaving the assessment interface.

Meta's AI app surged from No. 57 to No. 5 on the U.S. App Store within 24 hours of launching Muse Spark, Meta's new multimodal AI model. The model accepts voice, text, and image inputs and features reasoning capabilities for science and math tasks, visual coding, and multi-agent functionality.

OpenAI announced a $100 per month ChatGPT Pro subscription tier offering five times more Codex usage than its existing $20 Plus plan. The move directly challenges Anthropic's Claude Code, which generated over $2.5 billion in run-rate revenue in February with 100%+ growth since the start of 2026. Codex now has three million weekly active users.

Anthropic announced it is limiting Mythos, its newest model, to large enterprises and critical infrastructure operators rather than releasing it publicly, claiming the model's ability to discover software security exploits poses risks. The restricted rollout strategy mirrors planned approaches by OpenAI and may serve dual purposes: managing security concerns while preventing smaller competitors from using distillation techniques to replicate frontier model capabilities.

Zhipu AI released GLM-5.1, a 754-parameter model optimized for agentic engineering tasks. The model scores 58.4% on SWE-Bench Pro, outperforming Claude 3.5 Sonnet (57.3%), and demonstrates sustained reasoning capability over hundreds of iterations.
