Before You Build a Custom ML Model, Prove You Need One
A practical framework for deciding when off-the-shelf models have reached their limit—and when your data, economics, and constraints justify building your own.
LLMs, GPU infrastructure, inference latency, agent patterns, and production ML systems.

A practical loop for keeping AI agent evals fresh: capture production traces with outcome labels, curate the failures worth testing, convert them into property-based eval cases, and verify fixes against both evals and production failure rates.
Retrieve-for-Train suggests a practical design shift: learn repeatable search behavior offline, but keep live facts and permissions online.
Persistent memory is becoming an infrastructure feature. The harder problem is deciding what an agent may remember, trust, update, and forget.
TypeSafe AI's Jev does not want to write your email, explain quantum mechanics or generate an application. It wants to answer a smaller question quickly: given this state, which bounded decision should software make next?
The competitive edge is shifting from raw model size to disciplined systems that combine reasoning, tools, data and human judgment.
