Meta has been synonymous with open source ecosystems. Recently, its research arm, FAIR, completed 10 years of its contribution in the field of artificial intelligence and human-level intelligence. 

“If you look back at Meta’s history, we’ve been a huge proponent of open-source,” believes Ahmed Al-Dahle, Meta’s vice president for generative AI.

Currently, Meta has over 900 GitHub repositories. 

This year, Meta’s commendable effort towards open source has resulted in the introduction of state of the art models. Here’s a list of top must-known open-source AI models developed by Meta AI. 

Llama 

Meta has unexpectedly become the Robinhood of the LLM community, breaking the barrier of entry for a lot of developers to experiment with large language models ever since its launch in February 2023. Llama 2, which was launched later in partnership with Microsoft, in July 2023, changed the course of open-source language models once and for all. It is said that the company will be launching Llama 3 early next year. The best part is that it would be open source for researchers and commercial use as well.

Seamless Communication

Meta has introduced “Seamless,” a cross-lingual communication system, anchored by two core models—SeamlessExpressive for preserving expression in speech-to-speech translation, and SeamlessStreaming, a high-performing streaming translation model with an impressive two-second latency—these innovations are built on the foundation of SeamlessM4T v2, Meta’s latest foundational model. SeamlessM4T v2 showcases notable performance enhancements in automatic speech recognition and various speech and text translation capabilities. This release represents a substantial leap forward in real-time cross-lingual communication, underscoring Meta’s commitment to pushing the boundaries of language and expression.
