BITLABS東京 AI研究開発

Research

Research that makes AI work in production

We research transformer models, inference, and agent reliability, and prove ideas with PoCs before they reach production.

Public Lab Notes

We separate promising ideas from systems that actually ship

Some research and PoC work stays private under confidentiality.

Pre-training

Training models from scratch

Focus
Transformer architecture, data quality, and training efficiency.
Method
We design the architecture and data, then train at scale with 5D parallelism.
Signal
Models built for the task, not borrowed and forced to fit.

Fine-tuning

Adapting open and closed models

Focus
Domain behavior, tool use, and alignment.
Method
We fine-tune any model alongside regression checks and task scorecards.
Signal
Changes you can measure before release.

Inference

High-throughput serving

Focus
Latency, GPU efficiency, and scale.
Method
We study batching, KV cache, parallelism, and traffic together.
Signal
Predictable performance under real load.

Agents & RAG

Reliable agentic systems

Focus
Tool use, retrieval quality, and loop control.
Method
We replay traces, test permissions, and tune harness and loop behavior.
Signal
Agents that stay useful and in control.

Model & inference research

We study the model and the serving layer together

Check 01

How transformer architecture choices affect quality and cost.

Check 02

How 5D parallelism makes large-model training and serving efficient.

Check 03

How serving limits should shape model choice before the build.

Reliability

Production trust has to be earned with evidence

Check 01

Evaluation across quality, latency, safety, and control.

Check 02

Reliability testing for tools, planning, and escalation.

Check 03

Release criteria tied to governance and deployment needs.
