Amazon partners with OpenAI to sell ads inside ChatGPT via its DSP

Amazon has struck a deal with OpenAI allowing advertisers to buy ChatGPT ad inventory through Amazon's demand-side platform, with Delta Vacations among the first U.S. brands testing the integration. Ads will appear as sponsored text and image units below ChatGPT's free and Go-tier responses, purchased on a cost-per-click or cost-per-thousand-impressions basis and managed by Amazon's team, though OpenAI retains control over ad delivery.

Anthropic Researcher Coxon Quits AI Industry, Warns of Loss of Control by 2027

Jacob Coxon, who moved from OpenAI to Anthropic earlier this year specifically for its safety-focused reputation, has now left the AI field entirely, saying the industry is on a path toward building systems humans may not be able to control. He told the Wall Street Journal that even Anthropic cannot safely pursue advanced AI without government regulation or a broader industry slowdown, predicting things could spiral by the end of next year. Anthropic's Alignment Science Lead Evan Hubinger publicly backed Coxon, estimating a greater than 10% chance AI could cause human extinction within a decade.

Microsoft elevates Rust to Tier-1 language status, ties it to MSVC backend

Microsoft has designated Rust as a Tier-1 supported language for internal development, placing it alongside C++, C#, and TypeScript with full toolchain, tooling, and compliance support. As part of this effort, the company introduced rustc_codegen_utc, a new code generation backend that connects Rust's compiler to the MSVC backend used across Windows.

Simulation of 91,874 real agentic-LLM requests shows LRU still beats proposed KV-cache alternatives

A researcher replayed 68,266 requests from 393 Claude Code sessions and 23,608 Mooncake requests through a custom prefix-cache simulator, testing three approaches meant to outperform the standard LRU eviction policy used by vLLM, SGLang, LMCache and Mooncake Store. None of the alternatives beat the default LRU-over-radix-leaves baseline, and the analysis found that cache misses mostly come from rapid, seconds-apart tool-calling loops rather than sessions timing out after going idle.
