Publishing WASM Wheels to PyPI for Use with Pyodide
Simon Willison's Weblog6 hours agoTutorialPyodide 314.0 removes a long-standing distribution bottleneck by allowing WebAssembly-compiled Python wheels to be published directly to PyPI, so any package author can now distribute Pyodide-compatible packages without Pyodide team involvement. Previously, the team manually built and hosted over 300 packages. Simon Willison celebrated by publishing luau-wasm — a Lua-based scripting language compiled to WASM — using Codex with GPT-5.5 to automate the packaging workflow.

UN Report Warns AI Could Consume Drinking Water for 1.3 Billion People by 2030★ 72
INSIDE 硬塞 AI2 days agoEthicsINSIDE summarizes a United Nations University report arguing that AI’s environmental cost cannot be measured by carbon alone. The report projects AI-supporting data centers could use 945 TWh of electricity annually by 2030, while cooling water demand may exceed the annual drinking-water needs of 1.3 billion people. It also says inference dominates lifecycle energy use and that concentrated cloud infrastructure deepens global inequality.

Silia: A Tiny Transformer Architecture for Sub-10M Parameter Models
r/LocalLLaMA top day3 days agoPaperA student from India shared their first paper on r/LocalLLaMA, proposing Silia, a Transformer architecture for extremely small models.

The author frames the work as an early, small-scale exploration, limited by old hardware and restricted access to larger compute.
DeepSeek v4 Coding Scores Clash With Broader Frontier Benchmarks
r/LocalLLaMA top day3 days agoCommentaryA Reddit post questions why DeepSeek v4 can rank near the top of coding leaderboards while CAISI reportedly places it about eight months behind the US frontier. The author argues that both views may be compatible because coding benchmarks measure a narrow, heavily optimized slice of capability. For local users, the bigger question is how quantized DeepSeek v4 variants perform in real agent workflows, tool calls, cybersecurity, and abstract reasoning.
[AINews] Open Models, Model Labs vs Agent Labs, and the Untrainable★ 72
Latent Space3 days agoCommentaryThis AINews issue uses Sarah Guo’s essay as a lens for current AI industry debates: where open models matter, how agent labs differ from model labs, and what cannot be trained away. It also recaps discourse around Anthropic Fable/Mythos, Fable 5’s capabilities, Google’s DiffusionGemma, and maturing agent infrastructure. The central takeaway is that durable value may lie in integration, customer translation, maintenance, and intent rather than model scores alone.
