MiniMax M3
MiniMax M3 is served by 3 providers that kRouter can route to, with a 1.0M-token context window and pricing from $0.50 per 1M input tokens. Because more than one provider offers it, the price you pay depends on which one you route to — the same request, the same model, different bills.

What MiniMax M3 is suited for
A 1.0M window is large enough to hold a substantial part of a codebase in one turn, so it suits whole-repo refactors and long agent sessions where the history keeps growing. It supports extended reasoning, which helps on debugging and multi-step planning but spends output tokens on thinking before the answer appears — worth knowing when you set max_tokens. Tool and function calling are supported, so it can drive an agent loop. Cached input is billed at $0.25 against $0.50 fresh, which is the difference that matters most for agent work — the same context is resent on every turn.
