+ Tech stack · The models we actually run
Real models, real versions, real production hours.
Every LLM, framework and library below runs a live Creative Mantra product. Model routing is deliberate: Gemini as default for cost, Claude Sonnet only for high-stakes calls, MedGemma fine-tuned locally for vision annotation, YOLO11m for detection. Every request cost-tracked.
