OpenAI releases practical guide for Codex in daily work

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.

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.

NVIDIA released Nemotron 3.5 Lightning, a 30-billion-parameter mixture-of-experts model designed for specialized tasks in multi-agent AI systems, alongside NeMo Switchyard, an open source routing library. The model delivers up to 4x faster output speed and 30% faster agentic task completion compared to competitors in its class. Both tools enable enterprises to deploy customized AI across local systems, edge devices, and cloud infrastructure without rewriting applications.

OpenAI has released GPT-5.6-Cyber, a cybersecurity-focused model available through Daybreak Red for authorized vulnerability research, exploit validation, and security testing. The model is designed to support authorized security professionals in identifying and validating vulnerabilities. The release reflects growing demand for AI tools tailored to defensive security work.
