https://www.yashpokar.com/blog Notes on AI agents, evals, generative UI, infrastructure and data pipelines. en Tue, 27 Oct 2026 07:20:02 GMT https://www.yashpokar.com/blog/what-the-ai-engineering-market-actually-wants-in-2026 https://www.yashpokar.com/blog/what-the-ai-engineering-market-actually-wants-in-2026 Tue, 20 Oct 2026 00:00:00 GMT I read a lot of job postings and hiring reports this autumn to recalibrate my own stack. The signal is clear and a little humbling: agents, retrieval, evals and shipping to real infrastructure, with model hosting and fine-tuning further down than the hype suggests.

AG-UI 1.0 standardises it. What the protocol actually is, what the event stream looks like, and why I'd adopt it over a bespoke WebSocket.

No generated HTML, no eval. How the format works, where it fits next to AG-UI and A2A, and what I would build with it.

It is the eval set that tells you the prompt still works. A layered approach I now use on every LLM project: deterministic checks, calibrated judges, pre-merge gates, and sampled production traces.

It turned into a GST reconciliation system that makes money while nobody watches. Notes on side quests, scope, and knowing when to say yes.

The rule I use now, when LoRA earns its keep, and why the eval set has to exist before any of it.

Getting it in front of customers meant RAG, evals, guardrails, and letting go of the parts that only worked on stage.

A story about profiling before guessing, concurrency with a budget, and why idempotency is the feature that lets you go fast.
