The session you cannot take with you

https://earendil.com/static/og/posts/session-portability.png
Inference APIs are moving away from a simple, user-controlled model where sessions can be inspected, archived, and replayed, instead returning a mixture of text and provider-bound state that is non-portable. The authors propose a set of rules for inference providers and agent builders to adopt, including making local event logs canonical, storing data explicitly, and providing readable ...

The Religion of Speed

https://bear-images.sfo2.cdn.digitaloceanspaces.com/graybearding/roxy.svg
The pursuit of speed has become a moral position, where moving fast is seen as proof of seriousness, but real speed requires understanding, clear constraints, and well-made decisions. Slowing down means refusing to skip the part where work becomes legible, asking boring questions that ensure progress, not just motion.

The Economic Benefit of Refactoring

https://martinfowler.com/articles/exploring-gen-ai/donkey-card.png
A developer used a generative AI tool to refactor a 150,000-line codebase, reducing input tokens for a specific task by 83% from 159,564 to 27,360. The refactoring process involved breaking down a large file into smaller ones, reducing code duplication and improving the agent's ability to identify the smallest subset of files necessary to read.

Show HN: Distilling DeepSeek into GPT-OSS doesn't transfer censorship. Try it

https://cdn.prod.website-files.com/67c5c67a4c758597bd28fafd/6a6a22c9ba40f549734921be_Gemini_Generated_Image_2rsn3e2rsn3e2rsn.jpg
Researchers trained an American model on the outputs of a censored Chinese model and found that the student model did not learn the teacher's censorship behavior. The study also showed that distilling a strong teacher can provide domain-specific gains, and a well-taught 120B model can outperform frontier open releases at realistic token budgets.

Why is everyone trying to build a solid-state battery?

https://substackcdn.com/image/fetch/$s_!vKRJ!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F4e900154-ac91-4154-91fc-f48e8327a902_850x663.png
Solid-state batteries have potential advantages over lithium-ion batteries, including being lighter and safer due to the replacement of liquid electrolyte with a solid material. The major benefit of solid-state batteries is a substantial reduction in material scaffolding, which could eliminate dendrite problems and make batteries more energy dense and cheaper.
