Choosing the right model

Name	Type	Required	Description
axon-sovereign-1	use case	No	Complex reasoning, long documents, code generation, structured JSON output, multi-turn conversations.
axon-sovereign-1-mini	use case	No	Classification, entity extraction, short summaries, high-volume batch processing where latency matters.
axon-embed-1	use case	No	Building RAG pipelines, semantic search, document clustering, similarity scoring.

Note:All models are available in all supported regions. If you do not pass a data_residency parameter, requests default to au (Australia). Set this explicitly to comply with your organisation's data residency policy.
