DBRX is a large language model (LLM) developed by Mosaic under its parent company Databricks, released on March 27, 2024 under the Databricks Open Model License.345 It is a mixture-of-experts transformer model, with 132 billion parameters in total. 36 billion parameters (4 out of 16 experts) are active for each token.6 The released model comes in either a base foundation model version or an instruction-tuned variant.7

At the time of its release, DBRX outperformed prominent models such as Meta's Llama 2, Mistral AI's Mixtral, and xAI's Grok-1, in several benchmarks ranging from language understanding, programming ability and mathematics.689

It was trained for 2.5 months9 and reported using on 3,072 Nvidia H100s connected by 3.2 terabytes per second bandwidth (InfiniBand), for a training cost of US$10M.3
