About Our Lab
At trainloop, we’re creating AI systems that are as unique and specialized as the humans that guide them.
We achieve this through theory-driven research and tooling innovations across machine learning, information theory, and cognitive science.
In addition to research, we collaborate with organizations possessing unique datasets or specialized technological resources to train state-of-the-art reasoning models on their tasks.
our focus
Continual Learning
Exploring the emergent properties of models that are always learning
Information Theory
Capacity‑aware objectives that promote stable, interpretable reasoning.
Feedback Alignment
Novel environment and reward signal curation, aligned with the objectives of the humans guiding them.
Evaluation & Interpretability
Tools to understand both external behavior and internal symbolism of models.

Our collaboration
process
Identification of Research Objectives.
Provide us access to your real usage data through a simple integration or direct upload—no heavy implementation needed.
Model Development and Experimentation
Our experts apply the latest RL algorithms like DPO and GRPO to fine-tune your model for accurate reasoning and preferred responses.
Integration and Continuous Optimization
We deliver your custom, fine-tuned model ready to deploy via an OpenAI API-compatible endpoint, fully managed by our team.
Backed by Y Combinator (W25), we help developers build AI products they can trust.
