AI & Models

Inception Labs has released Mercury 2.5, a faster, cheaper, and smarter AI model built for high-throughput inference. Meanwhile, researchers have found that large language models can develop novel social biases through adaptive exploration, even without explicit training data, as detailed in a new study on Open Review. Over at Meta, the company is showcasing a personal AI agent called Muse, which emphasizes security and real-world capabilities. OpenAI also upgraded its image generation with Chat GPT Images 2.5, promising faster and more precise outputs.

Developer Tools & Engineering

For those building with the Rust-based Bevy engine, a comprehensive guide covers animation in detail, from player graphs to the big-picture architecture. The Argo Drive/Delta Fin project demonstrates pushing Kimi K3, a 2.8-trillion-parameter MoE model, to run at 1 token/s on a MacBook Pro by streaming from four SSDs — a striking example of memory hierarchy engineering. On the infrastructure front, American Express detailed its cell-based architecture for processing payments at scale, explaining how transactions route through cells and remain resilient even when services fail. A related essay argues that function arguments should not be treated as "colors" in programming languages, challenging a common misconception about capability passing.

Creative & Theoretical Computing

A new interactive visual project presents a topological picture book, rendering mathematical surfaces and spaces in a way that makes abstract topology tangible. In a more pragmatic creative hack, a developer documented how to turn an e-ink display into a printer, repurposing a screen into a working output device.

AI & Society

Terence Tao wrote on his Mathstodon account that open math problems are being non-renewably mined by AI — he warns that frontier models are consuming the supply of tractable, well-posed questions at an unsustainable rate. In a more immediate disruption, UK airports experienced hundreds of flight cancellations due to an air traffic control issue, with recovery lags stretching well into the afternoon. The systems-dependent nature of modern infrastructure continues to be a topic of concern and discussion across Hacker News threads.
