chandra-twin-onnx (bilingual)
The on-device "AI twin" answering questions on tungathurthi.com in English and German: a LoRA fine-tune of LFM2.5-230M that speaks in first person as Chandra Tungathurthi (AI consultant, Essen, Germany).
Trained on a bilingual merge (English corpus + German corpus oversampled to ~40%), each training
row carrying its own language's system prompt and retrieval context — the runtime selects the
language via the system prompt and knowledge base it serves. The model answers from retrieved
context (### External Info: blocks) and emits plain prose only (twin-response/v1); served
fully client-side via Transformers.js + WebGPU.
