A July 2026 field guide to choosing self-hosted open models by exact checkpoint, license, resident memory, usable context, workload quality, and production economics.

How a compact Python ML cheatsheet becomes useful when synthetic demos, metrics, pipelines, and version drift are tied to the model-review decisions they can actually defend.

A practical ML terminology guide for model reviews where feature definitions, data splits, task type, optimization behavior, overfitting risk, regularization, ensembles, and embeddings need to be discussed precisely.

A software-developer guide to the statistics that actually change data-science decisions: samples, estimates, uncertainty, effect size, bias, probability, distributions, and model metrics.

A long-form feature-screening workflow that uses correlation for quick linear checks, then adds redundancy clustering, mutual information, chi-squared tests, L1 models, tree importances, permutation importance, and domain review.

A practical explanation of ML metrics with decision tables for regression tolerance, rare-event classification, threshold tradeoffs, and the failure case where accuracy looked good but the decision failed.

A practical playbook for turning classifier scores into reliable probabilities that can support ranking, thresholds, SLAs, and cost-sensitive decisions.
