Learning in the Open

At my day job, I was asked to be more efficient with AI spend. The honest answer was a semantic router in front of every model, so I pointed my own coding agent at one. It broke. Five bugs later, the fixes are upstream, which means everybody gets them.

A confidence number is only worth what it lets you trust. I put nine decision models, open and hosted, through one test: keep only the answers each was 90% sure of, and score them, first on 111 hard AI-written questions and then on 1,599 questions labelled by 100 people each. Some earned the trust. Here is which, and under what conditions.

We keep asking chat models for decisions, then parsing the prose back into something code can branch on. TypeSafe's Jev skips the prose. I spent a few days reading the public material, then got access and measured it myself. Fast and accurate held up. On my two prompts, calibration error came out near 0.09, and a plain open model on my own GPU was calibrated at least as well.

A normal model is twelve editors who each read your draft once. A looped model is one editor who reads it twelve times. I spent this week working out what that buys you, what it costs, and where it stops working.

I wanted one place to decide which model answers and how hard it thinks. That surfaced a bug one event from the end of every stream. I fixed the wrong thing first, the schema proved the router right, and the real fix is now upstream in vLLM.

A laptop, a single GH200, and a semantic router between them, built to answer trivial requests locally and send the hard ones to the big card. Along the way, eleven things in that stack told me a confident falsehood. Not one of them was the model, and three of them were my own measurements.

I spent a night carefully A/B testing a model on a GH200. Then I upgraded the inference engine for an unrelated reason, re-ran the identical config, and got 43 percent more decode throughput and nearly four times the context budget. When open-weight architectures change this fast, the engine is the other half of the model, and it fails quietly.

Anthropic found a mental workspace inside Claude that shows what a model is thinking but not saying. It caught the model noticing it was under evaluation, and behaving better because of it. Here is why interpretability is now the missing instrument for agentic oversight.

What two decades of engineering failure analysis taught me about protecting people. Why every decision system needs a safety layer that can't be optimized around.
