What modalities does GLM-5.3-Flash support?
It supports text, image, and video inputs.
What is the maximum context length of GLM-5.3-Flash?
The context length is up to 1,048,576 tokens.
Is GLM-5.3-Flash suitable for agent-based or tool-calling workflows?
Yes — it is explicitly suited for long-horizon agent tasks and supports structured outputs and tools.
Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
