Future directions in LLM patterns and their development
Several promising LLM design patterns are emerging, with innovations coming from open source communities as well as frontier model developers, thus shaping the design patterns of future models. This section highlights some of these key innovations, including Mixture of Experts (MoE) architectures, Group Relative Policy Optimization (GRPO), Self-Principled Critique Tuning (SPCT), and emerging patterns documented in the publication OpenAI GPT-4.5 System Card (https://openai.com/index/gpt-4-5-system-card/).
MoE architectures are a type of neural network architecture where, instead of a single large network, there are multiple smaller “expert” networks. During inference, a “routing network” dynamically selects and activates only a specific subset of these expert networks based on the input, optimizing computational efficiency. Unlike dense models, which engage all parameters for every task, MoE models...
