What the people actually building AI said today. One page — a 2-min read.
The practical work of making agents dependable led today: longer caching, durable runs, and better ways to supervise coding agents. Builders also pointed to on-device voice AI and the growing gap between impressive demos and tools reliable enough for production.
OpenAI extends caching and fixes usage limits for 40,000 accounts
The API now supports 12-hour caching. Logged-in Codex and Work users can return to old conversations and still hit the cache. OpenAI also corrected a plan-limit mismatch affecting about 40,000 accounts and says affected users will receive credits.
Vercel is opening its durable agent infrastructure to other harnesses
Guillermo Rauch says the infrastructure behind Eve and Workflows will support harnesses such as Pi and OpenCode, whether run locally, on Vercel, or independently. It can also make Claude Code and Codex runs durable and observable, though he says embedding those tools requires an extra sandbox and is less efficient.
Aaron Levie sees task-specific agents becoming an enterprise standard
Levie expects autonomous systems dedicated to particular jobs or domains to become a lasting form of AI software. Better tool use, stronger domain judgment, and infrastructure for long-running work now let agents handle more sophisticated workflows, with human oversight still needed.
Gradium launches small, open-source voice models for on-device use
Matt Turck highlighted Gradium's new suite of small text-to-speech models designed to run on devices; he describes them as state of the art but gives no benchmark figures. He also said FirstMark led Daytona's Series B after leading its Series A earlier this year.
Peter Steinberger favors worktrees over subagents for coding work
Steinberger says his strongest workflow had Astra plan and run Codex CLI in worktrees while Sol 6.1 wrote code. A separate agent challenged and monitored the work, an approach he packaged as an OpenClaw plugin called “smart goal.”
Swyx says writing-model restrictions block a production workflow
Swyx says Opus writes well until a prompt contains restricted words, making it unreliable in the critical path of the AI media organization he wants to build. He also tried using Codex to make animated explainer videos and judged the result unsuccessful.
GStack now works with Capy's Captains software factory
Garry Tan says GStack is now Capy-aware and works with Captains, Capy's software factory feature. He offered no further technical details in the post.
