What input modalities does GPT-5.6 Terra support?
It supports file, image, and text inputs.
How does GPT-5.6 Terra compare to other models in the GPT-5.6 series?
It is positioned as a balanced model between the flagship Sol tier and the cost-efficient Luna tier.
Is GPT-5.6 Terra designed for structured output or tool integration?
Yes — structured outputs and tools are explicitly listed as tags, indicating native support.
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.
