Perplexity has opened its Personal Computer AI assistant to all Mac users after initially limiting access to subscribers on its $200 per month Max plan. The macOS app can run tasks across local files, apps, and the web, with most processing handled in the cloud rather than locally.
Perplexity AI has released a native macOS application for its Personal Computer AI agent feature. The app is now available to all Pro and Max subscribers and replaces the company's previous Mac software.
OpenAI has released three new realtime voice models through its Realtime API: GPT-Realtime-2 with GPT-5-class reasoning capabilities, GPT-Realtime-Translate supporting 70 input languages, and GPT-Realtime-Whisper for streaming transcription. The models are priced at $32-64 per 1M audio tokens for GPT-Realtime-2, and $0.017-0.034 per minute for the specialized variants.
Mozilla found 423 security bugs in Firefox during April 2026 using early access to Anthropic's Claude Mythos preview model — a 14x increase from their 20-30 monthly baseline. The company credits both improved model capabilities and refined techniques for filtering AI-generated findings.
OpenAI launched an optional Trusted Contact feature for ChatGPT that notifies designated emergency contacts when the system detects discussions about self-harm or suicide. The feature requires manual review by trained personnel before sending notifications, and does not share chat transcripts with contacts.
Google has released Gemini 3.1 Flash Lite, a high-efficiency multimodal model with a 1,048,576 token context window priced at $0.25 per million input tokens and $1.50 per million output tokens. The model supports text, image, video, audio, and PDF inputs with four thinking levels for cost-performance optimization.
Mozilla's Firefox team reports that Anthropic's Mythos model has discovered thousands of high-severity security vulnerabilities, including bugs that had remained undetected for more than 15 years. In April 2026, Firefox shipped 423 bug fixes compared to just 31 in April 2025, marking a 13x increase attributed to AI-assisted vulnerability detection.
Chinese AI labs leverage distinct organizational approaches to rapidly follow frontier model development, including heavy integration of student researchers, reduced internal conflicts over individual contributions, and cultural emphasis on execution over theoretical debates. Labs like Moonshot AI, 01.ai, and Zhipu AI benefit from researchers focused on meticulous engineering work rather than personal brand building.
Anthropic has released three new capabilities for Claude Managed Agents: dreaming (research preview) for pattern recognition and self-improvement, outcomes for defining success criteria with automated evaluation, and multiagent orchestration for delegating tasks to specialist agents.
AWS announced Amazon Bedrock AgentCore Payments (preview), enabling AI agents to autonomously discover and pay for APIs, web content, MCP servers, and other agents. Built with Coinbase and Stripe, the service supports micropayments through the x402 protocol with per-session spending limits and full transaction observability.
Zyphra has released ZAYA1-8B, a mixture-of-experts language model with 760M active parameters and 8.4B total parameters. The model scores 89.1% on AIME 2026, competitive with models exceeding 100B parameters, while maintaining efficiency for on-device deployment.
Google is testing a major upgrade to Gemini Agent, internally called "Remy," that can autonomously take actions on users' behalf including making purchases, sharing documents, and communicating with others. The experimental feature, available to Google AI Ultra subscribers, will monitor user preferences and handle complex tasks proactively across connected apps.
GitHub has published a research approach for validating AI coding agents when traditional correctness testing breaks down. The company proposes dominatory analysis as an alternative to brittle scripts and black-box LLM judges for building what it calls a 'Trust Layer' for GitHub Copilot Coding Agents.
GitHub has published research on validating agentic AI behavior when there's no single "correct" answer. The company proposes dominance analysis as an alternative to brittle scripts or opaque LLM-as-judge approaches for building a trust layer in GitHub Copilot coding agents.
Google is adding an 'Expert Advice' section to AI Overviews and AI Mode that will display quotes from Reddit, forums, and social media above links to sources. The update also adds creator attribution showing usernames and community names, and will recommend in-depth articles at the end of AI responses.
Anthropic has secured access to all compute capacity at SpaceX's Colossus 1 data center, adding more than 300 megawatts of new capacity within the month. As a result, the company is doubling five-hour rate limits for paid Claude Code users and removing peak hour restrictions for Pro and Max tiers.
Anthropic has doubled Claude Code's five-hour usage limits for Pro, Max, Team, and Enterprise users while removing peak hour restrictions for Pro and Max plans. The company also increased API limits by up to 1500% for input tokens per minute through a compute capacity deal with SpaceX's Colossus 1 data center.
Anthropic doubled Claude Code's five-hour rate limits across Pro, Max, Team, and Enterprise plans effective Tuesday, removing peak-hours throttling for Pro and Max users. The capacity expansion comes from an exclusive agreement securing all compute at SpaceX's Colossus 1 data center, which provides over 300 megawatts and more than 220,000 Nvidia GPUs.
Anthropic has updated Claude Managed Agents with a feature called 'dreaming' that allows agents to automatically review past interactions and refine their memories. The feature, available in research preview, can either automatically update agent memories or let developers approve changes manually.
Google DeepMind has released a Multi-Token Prediction assistant model for Gemma 4 26B A4B that achieves up to 2x decoding speedup through speculative decoding. The model uses 3.8B active parameters from a 25.2B total parameter MoE architecture with 128 experts and a 256K token context window.
