Microsoft releases Harrier embedding models with 32K context window, achieving 74.3 on MTEB v2

Google has released Lyria 3 Clip Preview, a music generation model available through the Gemini API as of March 30, 2026. The model generates 30-second audio clips from text prompts or images at $0.04 per clip, with a 1,048,576 token context window.

Google has released Lyria 3 Pro Preview, a music generation model capable of producing full-length songs with verses, choruses, bridges, vocals, and timed lyrics from text prompts or images. The model features a 1,048,576 token context window and charges $0.08 per generated song through the Gemini API.

GitHub has disabled Copilot's ability to insert promotional tips into pull requests following developer backlash. The feature, which injected Raycast ads into over 11,400 pull requests without explicit developer consent, was enabled when Copilot was mentioned in PRs it didn't create. GitHub's product manager acknowledged the decision was a mistake.

Microsoft has released Harrier-OSS-v1, a family of multilingual text embedding models trained with contrastive learning and knowledge distillation. The 0.6B parameter variant achieves a 69.0 score on the Multilingual MTEB v2 benchmark with support for 32,768 token context windows and 45+ languages.

Alibaba's Qwen division has released Qwen 3.6 Plus Preview, a free multimodal model available via OpenRouter with a 1,000,000 token context window. The model claims stronger reasoning and more reliable agentic behavior compared to the 3.5 series, with particular strength in coding and complex problem-solving tasks.

Google's Gemini Live is experiencing persistent voice quality issues following the recent Gemini 3.1 Flash Live update. Users report that voice options like "Capella" (British female accent) have deteriorated significantly, with speech patterns changing dramatically during conversations and audio artifacts like crackles and pops becoming prominent.

Microsoft is expanding Copilot Cowork availability and introducing a Critique function that enables one AI model to review another's output. The update also includes a new Researcher agent claiming best-in-class deep research performance, outperforming Perplexity by 7 points, and a Model Council feature for direct model comparison.

Microsoft has enabled its Copilot Researcher tool to simultaneously leverage OpenAI's GPT and Anthropic's Claude through two new features: Critique, which uses GPT responses refined by Claude, and Model Council, which displays side-by-side outputs with agreement/disagreement analysis. Both features are rolling out in the Microsoft 365 Copilot Frontier early access program.

Amazon Web Services unveiled an agentic AI system for streaming platforms combining Nova Sonic 2.0 (real-time speech model), Bedrock AgentCore, and the Model Context Protocol. The system delivers two core capabilities: context-aware movie recommendations based on mood and viewing history, and real-time scene analysis including actor identification and plot summaries.

Meta has released SAM 3.1, an update to its Segment Anything Model that adds Object Multiplex, a shared-memory approach for joint multi-object tracking. The new version achieves approximately 7x faster inference when tracking 128 objects on a single H100 GPU while improving video object segmentation (VOS) performance on 6 out of 7 benchmarks.

OpenAI shut down two projects in March 2026: the Sora AI video app (launched September 2025, operational for six months) and indefinitely paused the planned ChatGPT adult mode. The company cited sexual dataset management and illegal content elimination as barriers to the adult feature launch.

Anthropic is privately warning top government officials that its unreleased model "Mythos" makes large-scale cyberattacks significantly more likely in 2026. The model enables AI agents to operate autonomously with high sophistication to penetrate corporate, government and municipal systems. One official told Axios a large-scale attack could occur this year as employees unknowingly create security vulnerabilities through unsupervised agentic AI use.
