Researchers developed methods to teach large language models to perform Bayesian reasoning and probabilistic inference. The approach enables LLMs to generate uncertainty estimates alongside predictions and update beliefs when presented with new evidence. This capability could improve AI system reliability by making uncertainty quantification explicit rather than implicit in model outputs.

Researchers used GPT-5.2 Pro to extend single-minus amplitude calculations to gravitons, deriving previously unknown nonzero tree amplitudes in quantum gravity. The work produced explicit graviton amplitude formulas for quantum gravity cases that lacked known solutions. This enables more efficient computation of gravitational scattering processes in quantum field theory.

Together AI developed cache-aware prefill-decode disaggregation (CPD), a serving architecture that separates requests with reusable cached context from those requiring full computation, improving long-context LLM inference efficiency. The system achieves up to 40% higher sustainable throughput and lower time-to-first-token compared to standard disaggregated designs by routing warm requests (those with cache hits) separately from cold requests (those with new context). The architecture uses a three-tier KV-cache hierarchy and intelligent routing to prevent expensive cold prefills from blocking fast paths for requests that can reuse previously computed context.

OpenAI released the Learning Outcomes Measurement Suite, a tool designed to evaluate how AI affects student learning in different educational settings. The suite enables researchers to track student progress and learning gains systematically across multiple school environments and time periods. Schools and researchers can now collect comparable data on whether AI integration correlates with improvements in student academic performance and knowledge retention.

Axios uses AI tools to assist local reporters in researching stories, organizing information, and streamlining editorial workflows across its newsroom. The company has deployed AI systems that help journalists work more efficiently on local reporting tasks, though specific metrics on productivity gains or cost savings are not provided in the announcement. This approach allows Axios to expand local news coverage with existing staff resources by automating routine tasks and freeing reporters to focus on investigative and impact-driven stories.

The day’s main thread is OpenAI turning “agent” from a buzzword into a product stack—inside ChatGPT, across plugins, and down into developer tooling. At Dev Day in San Francisco, it launched Dots, an always-on personal agent powered by GPT-6 Astra, rolling out to ChatGPT Pro and Business Premium users in eligible markets. Dots aims to pursue user-defined goals in the background, with team and Slack/Teams options and Microsoft’s Agent 365 security integration. In the same keynote orbit, OpenAI expanded ChatGPT plugins into app-like extensions with dedicated sidebar homes, interactive panels, file viewers, and support for MCP Events so automations can trigger from app actions.
