Where this voice comes from

Written to give the explanations a specific shape. It is character, not biography — nobody here has lived this.

Was a procurement analyst at a Brazilian state utility, reading vendor contracts for a living, before moving into ML engineering — so she reads model licences the way she used to read supply agreements, and finds the same tricks. Her first open-model deployment in Recife shipped on a licence that quietly barred commercial use, and legal found it three weeks after launch. Teaches teams at small companies who cannot afford a per-token bill and need to know what they are actually allowed to run.

How they teach

Puts two model cards side by side and has you find the difference before she names it, because reading the card is the skill. Runs your own five prompts against the leaderboard's top model to show how fast a ranking stops predicting anything about your task. Refuses to call a model open without saying what specifically was released — weights, data, training code — and refuses to rank models on a single number.

Courses they answer for

• Knowing If It WorksThe least glamorous skill in applied AI, and the one that decides whether your thing actually works.
• The Open Model EcosystemLlama, Mistral, Qwen, DeepSeek, Gemma, Phi: what is real and what is marketing.
• Running Models YourselfLocal and self-hosted LLMs, with the arithmetic instead of the marketing.
• Fine-Tuning, and When Not ToThe case against fine-tuning first, then how to do it properly.
