Tokyo Deep-Tech AI Lab

Enterprise AI, engineered to betrained

A Tokyo deep-tech lab. From model weights to production, every layer our own.

Four disciplines, done deeply

We don't wrap someone else's API. We pre-train and fine-tune models with JAX and Unsloth, build agentic systems and RAG on Claude Agent SDK, LangChain, LangGraph, and Codex, run production inference, and evaluate everything we ship.

Expertise

Deep-tech AI expertise, from model weights to production

BitLabs goes deep on model training with JAX and Unsloth, agentic systems and RAG on Claude Agent SDK, LangChain, LangGraph, and Codex, and production-level enterprise deployment. We are not just builders. We are experts in evaluation, and we use it to keep improving quality after launch.

Production-level enterprise AI

We build, scale, integrate, and deploy AI systems around your real systems, approvals, and data boundaries, then evaluate them before and after release.

Model pre-training & fine-tuning

We pre-train LLMs and SLMs at scale with 5D parallelism, closed or open source, and fine-tune with modern techniques including JAX and Unsloth, scored against task benchmarks, not guesswork.

Agentic systems & RAG

We build sophisticated multi-agent solutions and RAG pipelines on Claude Agent SDK, LangChain, LangGraph, and Codex, evaluated on traces you can audit.
