Sandboxes now expire based on last use

Vercel Sandbox snapshots now expire based on when they were last used, not when they were created. Active snapshots stay alive as long as workflows depend on them, while unused snapshots expire on their retention policy. Every time a snapshot is used, its expiration timer resets. This lets you set shorter retention windows without worrying that a snapshot will disappear between sessions, making it safer to build long-running workflows on top of Sandbox persistence.

"Claude Code '400: no low surrogate in string' on every turn: repairing a permanently broken session transcript"

Originally published on hexisteme notes. A Claude Code session that returns API Error: 400 ... not valid JSON: no low surrogate in string on every turn is poisoned by a lone UTF-16 surrogate (a code point in U+D800–U+DFFF) baked into its on-disk transcript, and the fix is to close that session, strip only those lone surrogates from the offending line of the .jsonl file while leaving real emoji untouched, re-serialize that one line, and then claude --resume. The poison is already on disk and is p

Caching LLM responses is just content addressing

An LLM review costs money and a few seconds of latency. Reviewing the same diff twice should cost neither. CommitBrief caches every review, but the interesting part isn't that it caches — it's that the cache is content-addressed, so a hit is provably the same review, and there is no such thing as a stale one. Editing a single line of your rules file invalidates exactly the entries it should, and not one more, with zero invalidation logic anywhere in the code. TL;DR The cache key is a SHA-256 of

xAI Grok audio models now available on Vercel AI Gateway

Realtime voice, text to speech, and speech to text are all available through the with the same routing, observability, and spend controls as your other models.xAI's audio modelsAI SDK These capabilities are available on the AI SDK 7 release.

My First Look at NFTs on Solana

When I first heard about NFTs, I assumed they were just randomly generated JPEG collections—mostly apes and profile pictures that became valuable because of hype. After building one on Solana, I realized an NFT is much more than an image. It's simply a token with a unique set of rules. Coming from a Web2 background, my biggest question was: What actually makes an NFT an NFT? I expected there to be a special NFT object. Instead, I learned that on Solana, an NFT is just a token configured with the
