Boltzbit is an AI Research Lab empowering quants to transform their data into a competitive edge. Our deeply innovative Bayesian Online-Learning Transformer (BOLT) is a step beyond GPTs. Uniquely, the custom models learn from private data streams and user feedback at inference time. Delivered via Boltzbit's no-code platform, we have automated online fine-tuning and enterprise app generation in Big Data Reasoning use cases, such as data extraction at scale, generative analytics, and statistical modelling. All models are deployed and owned privately, as they adapt on proprietary data and workflows.
