MiniMax-M2 offers more intelligence per dollar (2.4× the Intelligence-Index-per-cost of the alternative), making it the stronger value for high-volume use. It is also open-weight, so self-hosting can reduce costs further at scale.
MiniMax-M2 vs o3-mini: which should you choose?
MiniMax-M2 — MiniMax multimodal model with an Intelligence Index of 30, a 262K-token context window and a blended price of $0.36/1M tokens (open weights).
o3-mini — OpenAI multimodal model with an Intelligence Index of 24, a 256K-token context window and a blended price of $0.7/1M tokens.
MiniMax-M2 vs o3-mini: MiniMax-M2 scores higher on the Intelligence Index. MiniMax-M2 leads overall capability (Intelligence Index 30.0 vs 24.0). MiniMax-M2 is the cheaper model to run at $0.36/1M blended tokens — about 1.9× cheaper.
Capability: intelligence, coding and agentic work
On the composite Intelligence Index the MiniMax-M2 scores 30.0 versus 24.0. Composite indices summarize many evaluations, but always test on your own workload before committing.
Context window and speed
The MiniMax-M2 accepts up to 262K tokens per request, which sets how much documentation, transcript or code it can reason over at once. In measured throughput, o3-mini generates faster (211 vs 77 tokens/s), which matters for interactive apps and high-volume pipelines.
Pricing and access
At blended per-token rates, MiniMax-M2 is the cheaper model to run ($0.36 vs $0.70 per 1M tokens). MiniMax-M2 is open weights and o3-mini is proprietary api. Open-weight models can be self-hosted, trading per-call cost for infrastructure you manage; for production also weigh rate limits, throughput and data-residency requirements.
The verdict
Both are credible choices in the ai model comparison space; the specification table above lays out every metric so you can weigh the trade-offs that matter to you. Pick the one whose strengths line up with how you will actually use it.

Methodology
Large language models are compared on independent leaderboard metrics: an Intelligence Index (a composite of reasoning and knowledge evaluations), Coding and Agentic indices where measured, community arena Elo, maximum context window, a blended API price per million tokens (weighted across cache-hit, input and output rates), and measured output speed in tokens per second. Where a model ships multiple reasoning-effort variants, we report its strongest variant. Benchmarks capture only part of real-world quality, which also depends on tool use, latency, safety and task fit — and this space moves quickly, so figures reflect the leaderboard snapshot on the page date.
