Roleplay fit
GLM models balance strong instruction-following with competitive pricing, a reasonable middle ground for most roleplay setups.
Context behavior
With a 204,800-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.
Cost for regular use
It sits in the mid-range on price, a reasonable pick for regular roleplay use without going for the cheapest option available.
