Is gpt-oss-120b fully open-source?
The model is described as 'open-weight', but the license, training data, and full openness (e.g., code, tokenizer, training recipe) are not specified in the provided information.
What does 'batch' in the model name indicate?
The 'batch' suffix likely denotes a batch-optimized variant (e.g., for high-throughput offline inference), but its precise technical meaning is not defined in the given source.
Does it support structured outputs and tool use?
Yes — 'structured_outputs' and 'tools' are explicitly listed in the model's tags, indicating support for these capabilities.
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.
