A 4-minute read for founders: Coinbase says its 9B fraud model cost under $100 to train, so the real question is whether you own the confirmed answers it learned from.
A 4-minute read for builders: a free CPU baseline scored 91.0% on 3,080 public bank tickets in my test, plus the cost formula and labelling bill to check.
A 4-minute read for platform leads: the router, eval gate, drift monitor and rollback a fine-tuned small model needs before its benchmark win becomes production.
A 4-minute read for founders: in a peer-reviewed study of 5,172 support agents, AI lifted the least experienced most, so here is a 90-day rollout plan built for that.
A 4-minute read for engineering leaders: a scored delivery check, built on DORA's 2025 industry survey report of 4,867 respondents, that shows whether AI gains will hold.
A 4-minute read for builders: a harness that times AI vs no-AI work on a greenfield task and a mature-repo fix, plus my 2-run demo that settles nothing yet.
A 4-minute read for founders: the stop check that caught 3 of 3 seeded retry loops at step one in Rex Circuit's 50-ticket test, and how to ship it by Monday.
A 4-minute read for engineering leads: why a passing run can still ship a wrong answer, and the check that caught all 3 cases in our small local test.
A 4-minute read for builders: two decision gates worth copying this week, one that isn't, and the one command that reproduces my small local CPU test.
After fourteen months of running LangChain in a production document-intelligence agent, a financial-services team faced a 3x abstraction overhead on every debugging session, breaki…
A health-tech team shipped an AI clinical-note summarizer with a plaintext prompt exposed directly to clinicians; daily active use was 8% of target at four weeks post-launch, and q…
The old framing—LangChain for workflows, LlamaIndex for retrieval—is outdated. Both frameworks now converge on overlapping territory, and this article provides a production-grade d…
