GLM-5.2
GLM-5.2 is served by 3 providers that kRouter can route to, with a 1M-token context window and pricing from $1.00 per 1M input tokens. Because more than one provider offers it, the price you pay depends on which one you route to — the same request, the same model, different bills.

What GLM-5.2 is suited for
A 1M window is large enough to hold a substantial part of a codebase in one turn, so it suits whole-repo refactors and long agent sessions where the history keeps growing. It supports extended reasoning, which helps on debugging and multi-step planning but spends output tokens on thinking before the answer appears — worth knowing when you set max_tokens. Tool and function calling are supported, so it can drive an agent loop. Cached input is billed at $0.50 against $1.00 fresh, which is the difference that matters most for agent work — the same context is resent on every turn.

GLM-5.2 FAQ
How much does GLM-5.2 cost?
GLM-5.2 is $1.00 per 1M input tokens and $4.00 per 1M output tokens. Cached input is $0.50, which matters a lot for agent work that resends the same context each turn.
Which providers serve GLM-5.2?
3 providers: CodeBuddy CN, GLM Coding (Z.ai), Alibaba Token Plan. Through kRouter you can switch between them by changing the route prefix, without changing your tool.
What is GLM-5.2's context window?
1M tokens, with up to 48K tokens of output. kRouter publishes this on /v1/models as context_length, so clients read the real number instead of guessing from the model name.
Is there a cheaper alternative to GLM-5.2?
Yes — GLM-4.7 ($0.75/1M in), GPT-5 Mini ($0.75/1M in), Gemini 3 Flash Preview ($0.50/1M in), Gemini 3.1 Pro ($0.50/1M in) are cheaper with comparable capabilities. A kRouter combo can send routine turns to one of those and keep GLM-5.2 for the work that needs it.
