MPT-30B

Open LLM with Scale, Speed & Smarts

What is MPT-30B?

MPT-30B is a 30-billion-parameter open-source language model developed by MosaicML as part of the MPT (Mosaic Pretrained Transformer) series. Positioned between lightweight 7B models and ultra-large LLMs like GPT-4, it delivers powerful language understanding, long-context reasoning, and strong instruction-following, with enterprise-grade performance and full openness.

With its open weights and flexible Apache 2.0 license, MPT-30B empowers developers and researchers to create intelligent systems without vendor lock-in or API limitations.

Key Features of MPT-30B

30B Dense Transformer Model

Designed to handle long contexts, logical chains, and structured generation tasks at scale.

Instruction-Tuned for Natural Interaction

Fine-tuned to excel in question answering, summarization, step-by-step reasoning, and fluent dialogue.

Long Context Support (up to 65K tokens)

Built for long-form document tasks, perfect for legal, technical, or academic text generation and summarization.

Multilingual Capabilities

Performs best in English but generalizes to additional languages for global applications.

Open-Source with Apache 2.0 License

Fully open weights and commercial-friendly, no usage restrictions for startups or enterprises.

Optimized for Cloud or On-Prem Deployment

Runs on multi-GPU setups and modern inference stacks, ideal for large-scale AI platforms.

Use Cases of MPT-30B

Deploy MPT-30B for advanced internal tools, knowledge management bots, and document interpreters.

Ideal for summarizing long documents, creating reports, or transforming structured inputs into human-like content.

Start with a strong open base model to build domain-specific instruction-tuned variants.

Create AI tools that help with explanation, documentation, or translation of code logic.

Test ideas or build scalable MVPs without relying on closed APIs or expensive hosted models.
