Hi, I'm Ishan Bhat.

I train small language models, build retrieval and search systems, and stress-test whether research ideas deserve to become products. I care as much about what's happening inside a model as what it scores.

Focus

aAI research

Training small language models from scratch, fine-tuning open-weight bases, and probing what models actually represent — concept and emotion probes, curiosity-like behavior, late-interaction retrieval, and state-space architectures. Internals over leaderboards.

bModel building

The unglamorous parts that decide everything: training infrastructure, hyperparameter sweeps, reading loss curves next to sample generations, and constructing synthetic datasets that keep their diversity instead of collapsing into one mode.

cSearch & knowledge

Semantic search, embeddings, and retrieval pipelines — plus a running obsession with a curiosity engine: expanding "people also ask"-style questions into an open-ended learning feed. Systems that make you explore, not just consume.

dSoftware & tooling

Developer tooling and the infrastructure underneath it: structured generation pipelines, TPU and SGLang deployments, DuckDB data work, and interfaces built on modern web stacks. Architecture and UX are the same concern, not two.
