Frontier models got expensive enough that model choice is now a real decision. What the Ramp billing data shows, and the routing rules I actually…
Late interaction embedding models beat dense retrieval by one NDCG point and cost 42x the index. Here is where that trade actually pays off in…
IBM tested agent memory across eight models. More memory made weaker models worse. How to calibrate the dose, and why prompt caching decides the bill.
Qwen 3.8 27B defaults to maximum reasoning effort on every prompt, even simple ones. Here's how to run it locally, spot the setting, and control…
Instead of shipping a 600-item enum to the model, let it invent a fake category and snap it to a real one with embeddings. Cheaper,…
My eval harness leaked model names into the judge prompt for six weeks. What two recent papers say about judge bias and calibration, and the…
My LLM evaluation tools said the agent was fine. Two long-horizon benchmarks explain why it fell apart in week three, and what I test differently…
Two new papers tested LLM synthetic data against real survey takers and peer reviewers. Every model missed the same things. Here is where I still…
Tool schemas quietly weaken your model's refusal behavior. Here is what a new agent-safety paper found and the checks I now run before shipping any…
RAG or fine-tuning? One question settles it most of the time. What the benchmarks leave out, where retrieval quietly fails, and the hybrid split I…
