What We Do

Our Expertise

From foundational research to deployed systems, we operate across the full AI stack.

LLM Training & Fine-Tuning

Pre-training, instruction tuning, RLHF, and domain adaptation of large language models tailored to your data and use case.

Computer Vision

Detection, segmentation, 3D perception, and multimodal vision-language systems for industrial and consumer applications.

Robotics

Perception pipelines, motion planning, and learned policies for autonomous robotic systems in unstructured environments.

MLOps

End-to-end ML infrastructure: training pipelines, model registries, serving at scale, monitoring, and continual learning loops.

Data Strategy

Data collection, curation, labeling strategy, synthetic data generation, and governance frameworks to fuel AI development.

IP Strategy

Intellectual property landscape analysis, patent strategy, and AI asset protection for companies building at the frontier.

About Us

AI Built on First Principles

Bayesian Brain LLC is an AI research and development consultancy based in San Francisco. We believe the best AI systems are not just technically powerful — they are built with principled reasoning, rigorous evidence, and a clear understanding of uncertainty.

Our approach is rooted in the Bayesian tradition: updating beliefs as evidence accumulates, quantifying what we don't know, and designing systems that remain robust in the real world. Whether you are training a large language model, deploying a vision system, or charting an AI roadmap, we bring deep technical expertise and intellectual rigor to every engagement.
