Pi's context compression approach retains a maximum of 2,000 lines or 50 KB for a single file or command output, and when the conversation approaches the approximately 16,384-token limit, it retains approximately the most recent 20,000 tokens while replacing earlier content with a model-written summary.

UnverifiedA 262K token context means the model can process approximately 200,000 Chinese characters in a single conversation, at the cost of the KV cache occupying large amounts of VRAM and memory as the context grows.72% similarVerifiedFor a typical 7B model with 32 layers and 32 attention heads, storing the KV Cache for each token requires approximately 0.5 MB of VRAM, so generating 1,000 tokens requires an additional ~500 MB of VRAM67% similarUnverified以80ms为帧长，持续5分钟的对话将产生约3750帧历史上下文，每层Transformer需为每帧存储键值对，总显存占用可达数十GB67% similarUnverifiedStoring a 1-million-token conversation now requires less than 1 GB of memory, whereas larger previous-generation models required at least 3.7 GB.67% similar
