## Resource

Today on UpNext AI: a new open-source AI "gap map" tries to measure what a public-option AI stack actually looks like, a medical AI paper tests whether common explanation tools are reliable enough to trust, and we round out the show with headlines on Mistral, AI-assisted software shipping, Indian IT dealmaking, and AI schooling for wealthy families. Covered stories: - Current AI launches its Open Source AI Gap Map, indexing open-source AI tools, models, datasets, and hardware projects. - A Scientific Reports paper evaluates feature selection methods and SHAP-based interpretability for arrhythmia-analysis models. - Theoria proposes a verification approach for checking AI reasoning states with explicit justifications. - TechCrunch profiles Mistral AI as an OpenAI competitor with open-source models and major funding momentum. - Simon Willison describes shipping sqlite-utils 4.0rc2 with heavy help from Claude Fable. - Livemint reports AI pressure is pushing Indian IT firms toward acquisitions. - The Verge reports some wealthy families are turning to AI-driven schooling through companies including Forge Prep.
