About
Falcon 40B is a leading open-source large language model developed by the Technology Innovation Institute in Abu Dhabi, featuring a causal decoder-only architecture with 40 billion parameters. It stands out with its use of rotary positional embeddings, multi-query attention, and FlashAttention, enhancing its contextual understanding and processing efficiency. Trained on 1 trillion tokens using the enriched RefinedWeb dataset, Falcon 40B excels in various natural language processing tasks, ranging from text generation to language translation and question answering. It supports multiple languages and is open under the Apache 2.0 license, promoting both research and commercial use. The model efficiently utilizes standard hardware, requiring around 85-100 GB of memory for inference, setting a benchmark for performance and scalability in its category.
Falcon 40B is an open-source model in the Falcon family. The structured metadata tracks structured outputs. This page tracks provider routes through Microsoft Foundry, GCP Vertex AI, Alibaba Cloud PAI-EAS, and 1 more, with the cheapest tracked route listed at $0.65 input and $2.75 output per 1M tokens.
