OpenAI Compatible

Powerful Core Models that fit your stack, not the other way around

Regolo.ai is built on the OpenAI API standard, the most widely adopted interface in the AI ecosystem. A single, familiar contract to manage text generation, embeddings, vision, and more, covering everything from prototyping to production.

Starting a new project? Use our documentation to get going in minutes. Already have an existing integration? Simply swap your base URL and API key, with no code rewrites and no new patterns to learn. Regolo works as a seamless drop-in replacement.

Leverage the tools and frameworks you already know and trust, including LangChain, LlamaIndex, the official OpenAI SDK, and many more, all without any friction. One standard, every model, zero lock-in.

Built for Every Use Case

From smart chatbots to automated document pipelines, explore the most popular ways teams put our models to work in production.

RAG and Knowledge Bases

Build Retrieval Augmented Generation systems that search across your private documents and deliver accurate, grounded answers. Combine embeddings, reranking, and chat models from a single provider.

Conversational AI

Create intelligent chatbots and virtual assistants that handle customer support, sales inquiries, and internal knowledge retrieval with natural, context-aware conversations.

Document Processing

Automate the extraction of structured data from invoices, contracts, and forms using OCR and vision models. Reduce manual data entry and accelerate business workflows.

Content Generation

Generate marketing copy, product descriptions, social media posts, and creative visuals at scale. Use text and image models together to produce complete campaigns.

Audio Transcription

Convert meetings, podcasts, and customer calls into searchable text. Build transcription pipelines that feed directly into summarization and analysis models.

Code Assistance

Power code completion, code review, and debugging tools with models specialized in programming tasks. Accelerate developer productivity and reduce time to production.

Custom Models

Your Models, Your Rules,
Our Infrastructure

Want more customization or need to host a specific model? Bring any model from Hugging Face, pick the GPU configuration that fits, and deploy on dedicated hardware in our European data centers. We download it, load the weights, and serve it. Ready to call in minutes.

Dedicated GPU Instances

OpenAI-Compatible Endpoints

Hourly Billing, No Lock-in

EU Data Residency & Privacy

Paste Your Model

Grab the Hugging Face URL of any supported model and add it to your Regolo library. We handle the download and setup on our infrastructure. No manual uploads, no friction.

Pick Your Hardware

Choose a GPU instance that matches your model's size and VRAM requirements. From lightweight inference to heavy-duty workloads, you have full control over the resources you need.

Deploy & Scale

Hit deploy and your model goes live on a dedicated endpoint. Scale GPU resources up or down as demand changes. Hourly billing, no long-term commitments, no surprises.
