Train-to-Test scaling explained: How to optimize your end-to-end AI compute budget for inference

The standard guidelines for building large language models (LLMs) optimize only for training costs and ignore inference costs. This poses a challenge for real-world applications that use inference-tim [...]

TikTok ripe with mental health misinformation, new study reports

The internet is both excellent and horrible at spreading information and community. In one sense, it can provide access to so many people and perspectives that aren't available in a person's [...]

New memory framework builds AI agents that can handle the real world's unpredictability

Researchers at the University of Illinois Urbana-Champaign and Google Cloud AI Research have developed a framework that enables large language model (LLM) agents to organize their experiences into a m [...]

Phi-4 proves that a 'data-first' SFT methodology is the new differentiator

AI engineers often chase performance by scaling up LLM parameters and data, but the trend toward smaller, more efficient, and better-focused models has accelerated. The Phi-4 fine-tuning methodology [...]

Google’s new framework helps AI agents spend their compute and tool budget more wisely

In a new paper that studies tool-use in large language model (LLM) agents, researchers at Google and UC Santa Barbara have developed a framework that enables agents to make more efficient use of tool [...]

Moonshot’s Kimi K2.5 is 'open,' 595GB, and built for agent swarms — Reddit wants a smaller one

Two days after releasing what analysts call the most powerful open-source AI model ever created, researchers from China's Moonshot AI logged onto Reddit to face a restless audience. The Beijing-b [...]

The Morning After: Everything Apple announced at WWDC 2025

Apple’s Worldwide Developer Conference (WWDC 2025) kicked off yesterday, with the usual glossy keynote from the iPhone maker. As ever, the company outlined the changes it’s made to its operating s [...]

Thinking Machines challenges OpenAI's AI scaling strategy: 'First superintelligence will be a superhuman learner'

While the world's leading artificial intelligence companies race to build ever-larger models, betting billions that scale alone will unlock artificial general intelligence, a researcher at one of [...]

Meta asks the Oversight Board to weigh in (a little) on Community Notes ahead of expansion

When Meta announced last year that it was ditching third-party fact checkers in favor of an X-style Community Notes system, the company was careful to note that it would only implement the changes wit [...]
