04 · Capabilities
Features and capabilities
⚡
Prompt caching
Cached input costs $0.266 per million instead of $0.0066, so stable prefixes get cheaper.
07 · Use cases
What can you do with GLM 5.2?
Debugging and root cause
Multi file failures where the model has to hold a causal chain before answering.
Architecture and planning
Design docs, migration plans and trade off analysis over long context.
Data analysis
Spreadsheets and logs read in one pass, then summarised with the numbers quoted back.
Agentic coding
Repo wide changes that need plan, edit and verify loops.
08 · Cost levers
Prompt caching and how to cut the bill
Cached input bills at $0.266 per million instead of $0.0066, a 81% discount. Keep the system prompt and documents first and the changing question last, so every call hits the cache.
