Chinese AI labs challenge U.S. leaders. Moonshot and Alibaba released open-source AI models they claim rival the best from OpenAI and Anthropic at a fraction of the cost, intensifying pressure on Silicon Valley and Washington.

The Verge framed the releases as a "one-two punch" to U.S. AI dominance. Both models are open-source, meaning developers worldwide can freely use and modify them, which could accelerate adoption outside American platforms. The cost gap, if the performance claims hold, raises questions about the sustainability of the heavy infrastructure spending by U.S. firms and may sharpen calls in Washington for new export or competitive policy responses.

San Francisco orders removal of 'nudify' apps. San Francisco's top prosecutor ordered Apple and Google to pull AI "nudify" deepfake apps from their app stores, estimating both companies earned millions in fees from the tools.

San Francisco District Attorney Brooke Jenkins sent the demand letters to Apple and Google, arguing the apps facilitate the non-consensual creation of sexually explicit images, which can constitute a crime under California law. Ars Technica reported the prosecutor estimated each company collected substantial fees through their standard app-store revenue-sharing arrangements, framing them as financial beneficiaries of the tools.

AI designs new CRISPR gene editors. Researchers used AI to design functional CRISPR enzymes—the "molecular scissors" that cut DNA in gene editing—not seen in nature, potentially expanding the gene-editing toolkit.

Traditional CRISPR systems rely on enzymes discovered in bacteria and other organisms. By using AI to design enzymes with no natural counterpart, researchers could potentially create editors with different targeting capabilities, sizes, or specificity profiles than existing tools allow. Nature's coverage suggests the work opens a path toward a broader, more customizable set of gene-editing components for medicine and research.

Wildfire-spotting satellites launch into smoky skies. The Google-backed FireSat program launched satellites that can detect wildfires other systems miss, as Canadian wildfire smoke continues to degrade air quality across U.S. cities.

FireSat's satellites are designed to detect smaller, earlier-stage fires than current monitoring systems can reliably identify, according to Ars Technica. The launch timing coincides with smoke from Canadian wildfires pushing air-quality indexes into unhealthy ranges across multiple U.S. cities, underscoring demand for faster fire-detection infrastructure as wildfire seasons grow more severe across North America.
