OpenAI has solved 10 long-standing mathematics problems, some unsolved for decades, using AI technology that identifies patterns across vast datasets. The breakthrough is prompting leading mathematicians, including Fields Medal winner James Maynard at Oxford, to reassess the future of their discipline as mathematics adapts to AI capabilities. The development signals that generative AI, already transformative in text, images, and scientific research, is now reshaping how mathematical problems are approached and solved.

Joby Aviation is acquiring Dayton, Ohio-based defense contractor Resonant Sciences for $500 million, financed through $450 million in cash and $50 million in equity. The deal, expected to close in early 2027, positions Resonant as Joby's dedicated defense division while the company's commercial air taxi business continues separately. The acquisition reflects Joby's strategic expansion into military markets alongside its consumer aviation ambitions.

Anthropic has committed to embedding machine-readable watermarks in Claude-generated text and images to comply with European AI transparency regulations. The watermarks will be invisible to humans but detectable by people and platforms seeking to identify AI-generated content. The company says the changes are a future commitment rather than an immediate rollout, and will include digitally signed provenance metadata where supported.

Manus, an AI startup acquired by Meta, announced Tuesday it will return to operating as an independent company following a Chinese government order in April to unwind the deal. The reversal marks a significant setback for Meta's AI acquisition strategy and reflects growing regulatory scrutiny of foreign tech acquisitions in China. The company said it is close to finalizing the separation.

LTX released LTX-2.5, an open-weights video generation model that produces 10-second clips in 6.8 seconds on Nvidia GB200 chips, with native multishot support and improved quality. The model is available free for organizations under $10 million ARR on Hugging Face, ComfyUI, and via API. LTX claims 33 million downloads across its model family and reports a 67% win rate in blind quality tests against competing models.

Mistral AI announced a three-part infrastructure expansion targeting 1 gigawatt of European compute capacity by 2030, starting from less than 200 megawatts today. The plan includes regional inference endpoints, a new Priority Tier with uptime guarantees, and a coalition of European enterprises making multi-year compute commitments to fund 200 megawatts by end of 2027. The company is also hosting third-party open models, including GLM-5.2 from Chinese AI lab Z.ai, marking a shift from open-weight model training toward critical infrastructure services.
