Roleplay fit
This is a Composite-hosted model, run and tuned directly on Composite infrastructure.
Context behavior
At 30,000 tokens, its context window is on the smaller side. It is a better fit for focused scenes or one-off chats than for a long-running campaign with heavy lore.
Cost for regular use
It is priced low enough for high-volume daily roleplay without the per-message cost adding up quickly.
