Key Questions Answered
How does LinkedIn adapt foundation models for its platform?
LinkedIn adapts foundation models through the Economic Opportunity Network (EON) project, which utilizes data from the LinkedIn Economic Graph to enhance model capabilities for specific user needs. This adaptation allows for rapid development of tailored AI experiences that improve job-candidate matching and other functionalities.
What are the key features of the EON models developed by LinkedIn?
EON models are designed to follow instructions, generalize to new tasks, and adhere to LinkedIn's Responsible AI principles. They utilize multi-task instruction tuning, reasoning traces, and reinforcement learning techniques to ensure high-quality outputs aligned with user expectations.
What performance metrics were used to evaluate the EON models?
The EON models were evaluated using standard metrics against state-of-the-art models on benchmarks like ARC, MuSR, and IFEval. Performance was also assessed in terms of cost efficiency, with the EON-8B model being significantly more cost-effective compared to GPT-4.
Key Statistics & Figures
Cost efficiency of EON-8B model
75x and 6x more cost-effective compared to GPT-4 and GPT-4o respectively
This cost efficiency was calculated based on the number of A100 GPUs needed for deployment.
