A Claude Code Stop hook that runs your tests every time Claude tries to finish, and sends it back to work when they fail.

Most LLMs are built to generate. Jev is built to decide. That difference sounds small, but it...

Most cost tracking keeps the attempt that worked and drops the ones that failed. Here is what that hides, and how to put every attempt on the bill.

A practical comparison of GitHub Copilot, Cursor, and Codeium based on coding workflows, context understanding, IDE integration, pricing, and real-world use cases.

Most classification and routing calls use a chat model, then parse prose and hope the JSON holds. The new /v1/systemone LLM decision API on LLM Gateway returns typed yes/no, choice, and score answers with calibrated probabilities, billed o…

A worked model of LLM cost optimization for a team spending $100k a month: what difficulty-based model routing saves at three traffic mixes, what the classifier costs, and the break-even point. Real catalogue prices, explicit assumptions, …

Automatic model selection now reads the request before it routes it. Choose the models `smart` may resolve to, and a classifier rates each prompt so a one-line fix goes to a cheap model and a hard problem goes to a frontier one. Available …

A live Smart Routing benchmark compares the same prompts across routed and fixed-model requests, including classifier charges, answer checks, and latency. See where routing saved money and where it missed.

Today's blog is mostly about the common ways cache misses have happened in our system, and how we...

Codex and Aider look alike from the outside: you type, the model edits your code. Inside they are...

The experiment was fine. The runner was the bug. A single hung API call discarded hours of...

A benchmark on whether LLMs check WHO said something before acting on it. Strip the source label off a rumor, phrase it like policy, and a model that correctly refused will spend your money. #kagglechallenge

I review more code than I write now. I'm not sure I'm getting better at it. It's a small,...
