This is an OpenAI model, a dependable baseline with broad instruction-following and consistent formatting across long conversations.
With a 1,050,000-token context window, it can hold a long-running roleplay or a full lorebook in memory without losing earlier plot details, so it suits multi-session campaigns and character cards with heavy backstory.
It is priced low enough for high-volume daily roleplay without the per-message cost adding up quickly.
