About MiniMax

MiniMax's M-series pairs the proprietary MiniMax Sparse Attention (MSA) architecture with native multimodal understanding and open weights, targeting long-horizon agent tasks and whole-codebase comprehension at up to a 1M-token context. On Synthorai the line sits behind one OpenAI-compatible endpoint (swap the base_url, keep your code) with live pay-as-you-go pricing and no MiniMax account required.

FAQ

How do I get a MiniMax API key without a subscription?

You don't need a MiniMax account: sign up on Synthorai, create one API key, and every MiniMax model on this page works through the OpenAI-compatible endpoint: pay-as-you-go, no subscription (models marked "invited beta" additionally need an approved application).

What does the MiniMax API cost?

Token-billed models start at $0.3/M input tokens; every model's live per-unit price is in the table above. These are provider list prices with no platform markup.

Can I use my own MiniMax key (BYOK)?

BYOK isn't available for MiniMax yet; requests run on Synthorai's managed channels at the listed rates.

What is MiniMax's data-retention policy via API?

Zero prompt retention at the gateway by default; MiniMax's API data policies apply upstream.
