Technical notes from TopxAI: model introductions, endpoint walkthroughs and what changed in the catalogue.
- · AI coding agents are moving the bottleneck to verification · What recent research says about agent productivity, why more output can slow delivery, and a practical evaluation worksheet for small engineering teams.
- · An AI API timeout is an unknown outcome, not a failed action · How to separate generation retries from tool execution, recover after an interrupted stream, and test duplicate effects before shipping an agent.
- · Why I paused an AI project: the cache bill missing from the architecture · Jevis had a detailed design for frontier-model planning and cheaper execution. Prompt-cache economics exposed the hypothesis we still had to test.
- · TypeSafe Jev: a System One model that returns judgments, not text · What Jev (jev-1.13.0) is, how noul, choice and score work, what the official docs say it is bad at, what it costs, and how to call it through TopxAI.
