Non-determinism in GPT-4 is caused by Sparse MoE

The article claims that the non-deterministic behavior of GPT-4 is due to its Sparse Mixture of Experts (MoE) architecture. This suggests that the model's output varies even with the same input, potentially due to the probabilistic nature of expert selection or the inherent randomness within the experts themselves. This is a significant observation as it impacts the reproducibility and reliability of GPT-4's outputs.

• •GPT-4's non-determinism is linked to its Sparse MoE architecture.
• •This implies that outputs can vary even with identical inputs.
• •The variability may stem from probabilistic expert selection or internal randomness within experts.
• •This impacts the reproducibility and reliability of GPT-4's results.
