Production-grade code completion at your fingertips – deploy Mellum instantly with full control and zero extra model fees

JetBrains Mellum – our focused large language model (LLM) for code completion – is now available on the Amazon Bedrock Marketplace. This means Mellum is easier than ever to use in real-world applications, with instant access via major cloud providers.

Whether you’re integrating AI into your existing software engineering workflows or launching a new ML-backed service, Mellum can now be deployed in seconds – with no additional model fees and complete control over inference costs.

How does it compare to Mellum’s open source version?

Earlier this year, we released an open-source version of Mellum on Hugging Face to support the developer community with an inspectable, adaptable model designed for code.

But the version available on Amazon Bedrock Marketplace goes further.

This is our production-grade Mellum, improved and optimized for enterprise deployment. It delivers better performance, greater stability, and is the same version we rely on internally at JetBrains for real-world workloads.

Flexible, cost-transparent inference

With Amazon Bedrock Marketplace, deploying Mellum is as simple as: 

1) Selecting the model from the Bedrock marketplace 

2) Choosing the GPU hardware that matches your performance/cost needs

3) Hitting deploy

You get full control over the hardware configuration and pricing, and Mellum runs without any additional licensing or model hosting fees. You only pay for the compute – and only for what you use.

Ideal for hands-on engineering use

Mellum on Bedrock is perfect for teams who want:

• Instant access to an advanced code-focused LLM
• Direct cloud deployment with no DevOps burden
• Transparent usage pricing and predictable scaling
• Seamless integration into modern engineering stacks

Use the right Mellum for the right job

1. Use the proprietary Mellum built into JetBrains IDEs

If you’re looking for the most polished developer experience inside JetBrains IDEs, enjoy the proprietary version of Mellum that is already built into the JetBrains AI Assistant. It offers deep IDE integration and an out-of-the-box experience optimized for productivity.

2. Use Mellum from Hugging Face for full control and customization

If you prefer full control and want to self-host or customize the model, the open-source Mellum on Hugging Face is ideal. It’s fully inspectable, adaptable, and free to use under the Apache 2.0 license.

3. Use Mellum on Amazon Bedrock Marketplace for Unified and Managed Endpoints 

And if you want a production-ready model with easy deployment in the cloud, Mellum on Amazon Bedrock Marketplace is the way to go. You get instant setup, transparent pricing, and the freedom to choose your preferred GPU setup – all without additional model fees.

Whether you’re self-hosting, building your own cloud pipeline, or using JetBrains tools directly – Mellum is ready to meet you where you are.
