• Context window limits hinder large language model usage. • Context packing packs multiple messages into single prompt. • Docker Model Runner supports context packing techniques. • Enables longer conversations without exceeding limits. • Useful for code generation and complex queries.

Article Summaries:

  • Philippe, a Principal Solutions Architect, explains how local language models often hit context‑window limits, especially on smaller models. He notes that the total token count-including system prompts, user messages, history, and generated output-must stay below the model’s context size (e.g., 8192 tokens for many Docker Model Runner engines). While the context size can be increased in compose.yml or via Docker commands, larger sizes can degrade performance on small models. The article introduces “context packing” as a technique to fit more information into the limited window, enabling longer conversations without exceeding token limits.
