MiniMax API

MiniMax is an artificial-intelligence company and model provider offering large language models through hosted APIs, including models designed for coding, reasoning, and tool-using agent workflows. It is used as a model provider by agent frameworks such as Hermes Agent.

MiniMax H3 is MiniMax's general-purpose omnimodal generative system for understanding text, images, video, and audio and generating video with native 32 kHz stereo audio. It supports 4–15-second outputs at 24 FPS across a wide range of aspect ratios; the shorter side is 768 pixels by default, with 2K generation available through H3-Regenerate-2K. Its H3-Base-FL2VA variant supports text-to-video, first-frame-to-video, last-frame-to-video, and first-and-last-frame-to-video modes, while H3-Base-Ref2VA accepts mixed image, video, and audio references. The repository also provides a prompt-writing skill and style-specific video-generation skills for the MiniMax Hub canvas workflow. H3 is available through MiniMax's global and China APIs, web apps, and desktop apps; the video describes its weights as open and runnable at 768p.

H3 Max is fal’s post-trained video-generation model, based on MiniMax’s open-weight video model. It combines model post-training with systems and hardware optimization to reduce generation time while maintaining video quality, supporting fast generation, interactive streams, and professional video workflows. Its continuous-video experiments can retain previous scene context and respond to new directions while a stream is running, with development focused on controllable camera movement, lighting, characters, motion, and lip sync.

MiniMax Music 3 is a music-generation model from MiniMax AI that creates complete songs of up to five minutes from lyrics and a music description. Lyrics can use section tags such as verse, chorus, bridge, instrumental, solo, and outro; the music description specifies style, emotional progression, vocals, instrumentation, arrangement, and production. A structured-caption format can organize these instructions into global metadata, vocal details, and arrangement sections. The model uses a hierarchical autoregressive hybrid architecture: an 8B Global LLM predicts the first residual-vector-quantization codebook frame by frame to model long-range musical structure, while a 0.6B Local LLM predicts the remaining acoustic codebooks within each frame. Its continuous hidden-state synthesis module combines the two models' final hidden states with Flow Matching and Flow-VAE to produce 32 kHz, 16-bit stereo WAV audio, preserving information for vocal articulation, instrumental texture, and temporal continuity.

H3 Max Director is a public AI model for action-controlled continuous video. It maintains memory of previous scenes and accepts live prompt-based direction while video is running, enabling control over elements such as camera movement, lighting, characters, motion, and lip sync. It is described as fal's post-trained version of MiniMax's open-weight video model, combined with systems and hardware optimization for real-time generation.
