tool use — A model's ability to call external functions — run code, search the web, edit files — instead of only generating text.
prompt caching — Reusing the model's processed form of a repeated prompt prefix so subsequent calls skip re-reading it, cutting cost and latency substantially.
context compaction — Summarizing an agent's earlier conversation to free room in the context window so a long session can keep going.
