Mosaic ML FAQ

What is the primary architectural innovation behind the DBRX model that makes it highly efficient?

DBRX utilizes a sparse mixture-of-expert (MoE) architecture. This design allows it to achieve extraordinary capabilities with only 36 billion active parameters, making it fast and efficient compared to dense models of similar performance.

How does Mosaic AI ensure the trustworthiness of images generated by models like Shutterstock ImageAI?

Shutterstock ImageAI is trained exclusively on Shutterstock’s proprietary image repository. This ensures that the generated images are based on trusted, high-quality data, addressing concerns about data provenance and ethical sourcing.

Can I train my own custom BERT model using Mosaic AI, and what is the approximate cost?

Yes, you can pretrain your own BERT model on your data from scratch using Mosaic AI. This service is available for approximately $20.

What is the distinction between the MPT-30B and MPT-7B models within the MPT family?

The MPT-30B model prioritizes quality, offering higher performance for complex tasks. In contrast, the MPT-7B model prioritizes efficiency, making it suitable for applications where computational resources or inference speed are critical.

What specific hardware optimization does Mosaic AI leverage for performance in its deep learning stack?

Mosaic AI's deep learning stack leverages FP8 (8-bit floating point) on H100 GPUs to achieve significant performance improvements for training, fine-tuning, and deploying large models, enabling faster LLM inference.

How does LLM Foundry facilitate the development lifecycle of large language models?

LLM Foundry is an open-source codebase designed for high efficiency across the entire LLM development lifecycle. It provides tools and frameworks for training, fine-tuning, and evaluating LLMs, streamlining the process from experimentation to deployment.
