What is LLMProc and how does it differ from traditional agent frameworks?LLMProc reframes LLM applications as Unix-like processes rather than agents. It provides powerful abstractions like fork for parallel exploration, goto for context management and time-travel debugging, and a file descriptor system for handling large tool outputs. This process-based approach makes scaling and managing LLM execution more intuitive using familiar computing paradigms.How does minLoRA achieve such parameter efficiency?minLoRA implements Low-Rank Adaptation (LoRA) in just ~100 lines of code. It freezes pre-trained model weights and injects trainable low-rank decomposition matrices, dramatically reducing trainable parameters from millions to thousands. Built on PyTorch's native parametrization system, it works seamlessly with any torch.nn.Module without modifying model definitions.What makes Additive Rotary Embedding different from standard RoPE?Additive Rotary Embedding (AddRoPE) modifies RoPE by making position encoding additive rather than multiplicative, with learnable weights and phase offsets. This allows models to selectively ignore certain frequencies and provides more natural attention patterns. In experiments, it matches or slightly outperforms RoPE while being computationally faster.
