MiniMax | 1,048,576 token context | $0.30/M input, $1.20/M output. MiniMax-M3 is a multimodal foundation model from MiniMax. It supports text, image, and video inputs with text output, a 1M-token context window, and is suited for long-horizon agentic work, coding, and tool use. It is built on MiniMax Sparse Attention (MSA), which replaces full attention with KV-block selection to cut per-token compute at long context — roughly 1/20 the cost of the previous generation at 1M tokens, with substantially faster prefill and decode while retaining quality across most tasks. Trained as a native multimodal model on interleaved data and tuned for multi-turn, production-like collaboration via an interactive user-simulator framework, the model is oriented toward sustained, multi-step tasks rather than single-turn execution.
MiniMax M3 is a 428B-parameter sparse mixture-of-experts model from MiniMax, activating roughly 23B parameters per token, with a 1-million-token context window and native support for text, image, and video inputs. Its MiniMax Sparse Attention architecture cuts per-token compute to about 1/20th of the previous generation at full context, with 9× faster prefill and 15× faster decode. Weights are open, the API is cheap, and the design targets sustained agentic work rather than one-shot queries.

Known for

  • 1M-token context at a fraction of the compute cost of dense attention models
  • Native multimodal training across text, image, and video from the first step
  • 9× prefill and 15× decode speedups over M2 at maximum context
  • Three switchable reasoning modes: always-on, adaptive, or disabled
  • Tuned for multi-turn agentic tasks and tool use, not just single-turn prompts

Watch out for

  • At 428B total parameters, local deployment demands serious hardware; check VRAM requirements before downloading.
  • Open weights, but verify the licence terms for your use case before building a commercial product on top.
  • Video and image input quality at extreme context lengths is not independently benchmarked here.

Prompts to try

Multi-file refactor task
You are working on a Python web scraper split across three files: fetcher.py handles HTTP requests with retries, parser.py extracts structured data using BeautifulSoup, and main.py orchestrates the pipeline. The scraper silently drops items when a page returns a 429. Diagnose the likely cause, propose a fix with exponential backoff, and rewrite the relevant sections of fetcher.py and main.py to implement it.
Long document Q&A
I am going to paste a long contract below. Read the entire document, then answer these three questions: 1) What are the termination conditions for either party? 2) Are there any automatic renewal clauses, and if so what notice period applies? 3) Which party bears liability for data breaches? Cite the clause number for each answer. [Paste contract text here]
Image-grounded analysis
Attached is a screenshot of a dashboard. Identify every metric visible, note which ones are outside a normal operating range based on what you can see, and suggest the two most likely root causes for any anomalies. Then write a three-sentence summary a non-technical manager could read.

Questions people ask

Can I run MiniMax M3 locally?
Yes, the weights are open and hosted at MiniMaxAI/MiniMax-M3 on Hugging Face. MiniMax supports SGLang, vLLM, Transformers, KTransformers, unsloth, and ATOM as inference frameworks, though at 428B total parameters you will need substantial hardware.
What does MiniMax M3 cost via API?
The API is priced at $0.30 per million input tokens and $1.20 per million output tokens, with a 1,048,576-token context window.
How is M3 different from M2?
M3 replaces full attention with MiniMax Sparse Attention, delivering 9× faster prefill and 15× faster decode at 1M context while reducing per-token compute to roughly 1/20th of M2; it also adds native video input and a configurable reasoning mode that M2 did not expose.
Captain's verdict
A rare open-weights model that takes the million-token context window seriously enough to rebuild the attention mechanism around it.

7,000°
Floor
The scale runs from 0° to 9,999°. Everything below 7,000° is kept for models no source reports on yet, which carry a stand-in number there so lists stay complete. 7,000° is where measured data begins: a model with real data but almost no downloads sits at the floor, and the measurements fill the degrees above it. The floor says nothing about the model; only the degrees above it do, and they are what separates one model from another.
+1,727°
OpenRouter tokens
5,730,756,128,120 tokens this model processed through OpenRouter in the last 30 days, prompts and answers together. Every 10,000,000 tokens count as one download in the download term, 573,075 in all; the last day's tokens join the adoption rate. Source: OpenRouter (openrouter.ai/rankings).
+324°
Adoption rate
About 20,825 downloads a day, measured between two readings of the sources, never guessed from a lifetime average. Speed weighs a quarter of the download term, so a fresh surge shows without letting a one-day spike outrank years of use.
Show detailed breakdown
Every number on this site can be checked. This model's heat score is 9,051°, and here it is built one ingredient at a time, with the running total after each: the floor, the degrees each source adds, the bonus for the kind of model and what the age of its weights takes away. The colors are the bands of the chart above. The glossary at the end defines every term.
  1. 1
    Start at the floor.
    Why 7,000° and not zero: the scale runs from 0° to 9,999°, and the part below 7,000° is reserved for models no source reports on yet, which carry a stand-in number there so the lists stay complete and never outrank a model with data. 7,000° is where measured data begins. A model with real data but almost no downloads sits here; everything that follows is measurement, and the room above the floor holds ten tenfold steps in downloads at 300° each. The floor is the same for every model, so it decides nothing; the degrees above it do.

Glossary: the terms used here
Heat score
One number for how much a model is used and wanted right now, from 0° to 9,999°. Every list on this site that says hottest is sorted by it and nothing else.
Floor
The 7,000° every model with real data starts from. The scale runs from 0° to 9,999°; the part below the floor is reserved for stand-ins (models without data), so that a model with data always ranks above one without. The floor is the same for everyone and decides nothing; the degrees above it are the measurement.
Download-equivalents
Everything the score treats as a download, added up: downloads themselves, each torrent seeder as 1,000, each AI Horde image and each run on a generation site as one.
Log scale
Counting by tens, not by ones: going from 1,000 to 10,000 downloads adds the same degrees as going from 10,000 to 100,000. It keeps giants from crowding out everything else.
Likes
Thumbs up and likes from every source, worth half a download each on the log scale.
Adoption rate
How many downloads a day a model gets right now, from the difference between two readings of a source. A quarter of the weight of the download term.
Measured and estimated
Measured means two readings of a source exist and the difference is real. Estimated means only today's total is known and the past is spread over the model's life; the site says which one it is showing.
Seeder
Someone who keeps a copy of the weights online for others to download over a torrent, or a hosted mirror doing the same. Each one counts as 1,000 downloads.
AI Horde
A volunteer network that generates images for free on donated computers. The number of images it has made with a model is public, and each counts as one download.
Generation sites
Sites that host their own copies of a model and let people generate with it, such as PixAI, SeaArt and Yodayo. Their downloads count like Civitai's and each generation run as one download.
OpenRouter tokens
A text model served through an API, such as Claude or GPT, has no weights to download, so its usage is measured in tokens: the pieces of text it read and wrote through OpenRouter, a gateway many apps use, over the last 30 days. Every 10,000,000 tokens count as one download. Source: OpenRouter (openrouter.ai/rankings), CC BY 4.0.
Full model (checkpoint)
The weights themselves, the file that generates on its own. It gets a bonus because add-ons depend on it.
LoRA and embedding
Small add-on files that steer someone else's weights toward a style, a character or a concept. They cannot run alone.
Family and weights
The base a model is built on, such as SD 1.5, SDXL, Flux or Wan. Every model inherits the release date of its family's weights.
Age
Degrees taken off for how long ago the family's weights came out: 150° a year, up to 750°. It keeps old downloads that had years to pile up from freezing the top of the list.
Family boost
A small, bounded nudge for LoRAs of a family this site is pushing forward right now, always listed in the breakdown.
Stand-in score
A stable number below the floor given to a model no source reports on yet, so lists stay complete. It never ranks above a model with data.
New! (grace period)
A model less than 7 days old shows New! instead of a score and holds no place in the rankings. Its score is computed from day one, but a model one day old grows faster than anything, so without the wait the week's #1 would always be whatever came out yesterday rather than what held up for a week.
Trend
How a model's growth over a period compares with the typical model's growth over the same period. Faster than typical reads as a rise, slower as a fall.
Typical model
The middle of the catalog: half the models with a figure grew faster over the period, half slower.
How this model's popularity has moved against the rest of the catalog: its growth in downloads, likes and usage over each period, measured against the typical model's growth over the same period, with its heat score at the time. Above the typical growth reads as a rise, below it as a fall. The past is reconstructed from today's totals, the model's first day and its measured download speed where two readings exist; a model that did not exist at the start of a period shows n/a.
