How we price

Order

Providers are listed cheapest input rate first, then by output rate, a tie going to the creator's own listing. A provider that lists the model without a published rate sits at the end.

Prices

Base-tier, on-demand rates in USD per 1M tokens, converted at ECB reference rates where a provider publishes in another currency. Cached-input and batch rates show only where a provider publishes them. "Cheapest" marks the one provider with the lowest input and output pair; a tie wears no badge.

Cost

Input rate times the input tokens plus output rate times the output tokens, at the monthly volume set above the table. Cached-input, batch, long-context and reasoning-token billing are not modelled.

Transparency and funding

Heads up: Base-tier, on-demand rates per 1M tokens; cached, batch and long-context tiers excluded. A provider may serve a shorter context or a quantized build than the creator's release. Verify before provisioning. More on how we price.

Estimated cost to self-host

MiniMax-M3.1-Flash needs about 241 GB of GPU memory at 4-bit with 32K context. The cheapest rental that fits is 8× RTX A6000 at about $3,398 a month.

That costs the same as roughly 15B tokens a month on MiniMax's API. Self-hosting is more expensive below that volume.

Estimates based on median on-demand rates for Nvidia GPUs. Memory is weights plus KV cache for one request, using FP8 KV cache where supported and FP16/BF16 otherwise. Break-even assumes a 5:1 input-to-output ratio. No guarantee of runtime support, usable performance, or that a matching quantized build exists. Pricing methodology.

Common questions

What is MiniMax-M3.1-Flash good for?

Coding, agent workflows, computer use and security work over text, images and video. Open weights under the MiniMax Community License on a multi-GPU node, and MiniMax prices it at the lower-cost end of its lineup.

When is MiniMax-M3.1-Flash not a good fit?

Audio input: it takes text, images and video and returns text only. Self-hosting takes a multi-GPU node, the MiniMax Community License has its own terms rather than Apache 2.0 or MIT, and no maximum output is published.

What is the cheapest way to run MiniMax-M3.1-Flash?

Hosted, unless you push serious volume. MiniMax charges $0.15 in / $0.60 out per 1M tokens. The cheapest rental that fits is 8x RTX A6000 at $3,398 a month, which costs the same as about 15B tokens a month on that API.

How does MiniMax-M3.1-Flash compare with MiniMax-M3?

MiniMax says M3.1-Flash keeps MiniMax-M3's mixture-of-experts design but swaps its first three full-attention layers for sparse attention, adds quantization-aware training and a new speculative decoding head, and does much better on agent, coding, computer use and security tasks. Same 1M-token context and text, image and video input. MiniMax-M3.1-Flash lists at 50% less per 1M input tokens and 50% less per 1M output tokens than MiniMax-M3. It came out 4 months later.

Can I self-host MiniMax-M3.1-Flash?

Yes. The weights are released under the MiniMax Community License. At 4-bit it needs about 241 GB of GPU memory, which starts at roughly $3,398 a month on the cheapest rental that fits.
