DeepPavlov
Open source conversational AI framework with prebuilt NLP pipelines, dialog management, and SOTA models for chatbots, Q&A, NER, and classification.
Overview
DeepPavlov is a production oriented conversational AI stack that ships modular NLP components, pretrained models, and dialog orchestration so teams can assemble assistants without rewriting core blocks. It supports tasks like intent classification, named entity recognition, slot filling, question answering, and ranking, with PyTorch and Transformers under the hood. You can wire components by config, fine tune on your data, expose REST endpoints, and deploy with Docker or Kubernetes.
The project also maintains reference assistants and the Dream architecture to demonstrate multi skill dialog. Because it is open source, engineers can audit code, extend models, and avoid vendor lock in while still benefiting from an active community and tutorials. For academia and startups, DeepPavlov is a practical base for pilots that must evolve into maintainable services, bridging experiments and production with tested pipelines and utilities.

Capabilities
Config Pipelines
Compose tokenizers models and policies by configuration then swap components without rewriting the service.
Fine tuning
Customize pretrained models on your data to raise accuracy on intents entities and answers for your domain.
APIs and Containers
Expose REST endpoints and deploy with Docker or Kubernetes to scale assistants reliably.
Reference Assistants
Use Dream and example bots to learn multi skill orchestration and best practices before customizing.
Frequently Asked Questions
How does pricing start?
DeepPavlov is free and open source, commercial support and partnerships are available through the team if needed.
Does it require GPUs?
Training benefits from GPUs but many inference pipelines run on CPUs depending on latency targets.
Is it production ready?
It includes serving utilities containers and examples that help move from notebooks to services.
Can I add new skills?
Yes, define components and wire them into the pipeline using configuration files.
What licenses apply?
The core library is open source, review the repository license for details.
