By pairing scalable reinforcement learning, high-speed inference, and ultra-low cost, MiniMax M2.5 positions itself as a production-ready engine for complex agent-driven applications.

Opus stands out as our leading model, outpacing rival systems across a variety of key metrics used to evaluate artificial intelligence, such as the assessment of undergraduate-level expertise (MMLU), graduate reasoning capabilities (GPQA), and essential mathematics skills (GSM8K), among others. Its exceptional performance is akin to human understanding and fluency when tackling complex challenges, placing it at the cutting edge of developments in general intelligence. Additionally, all Claude 3 models exhibit improved proficiency in analysis and forecasting, advanced content generation, coding, and conversing in multiple languages beyond English, including Spanish, Japanese, and French, highlighting their adaptability in communication. This remarkable versatility not only enhances user interaction but also broadens the potential applications of these models in diverse fields.

Odyssey-2 is an innovative interactive video technology that enables users to generate real-time video experiences tailored to their prompts. By simply inputting a request, users can watch as the system begins streaming several minutes of video that intuitively responds to their interactions. This groundbreaking advancement redefines traditional video playback, transforming it into a dynamic, responsive stream where the model functions in a causal and autoregressive fashion, creating each frame based on prior visuals and user actions rather than following a predetermined timeline. As a result, it allows for effortless transitions between camera angles, settings, characters, and storylines, enhancing the overall viewing experience. The platform boasts rapid video streaming capabilities, starting almost immediately and producing new frames roughly every 50 milliseconds (approximately 20 frames per second), which means users can dive straight into a captivating narrative without lengthy delays. Furthermore, the underlying technology employs a sophisticated multi-stage training process that evolves from generating static clips to offering limitless interactive video journeys, enabling users to issue typed or spoken commands as they navigate through a world that continuously adapts to their input. This remarkable methodology not only boosts viewer engagement but also fundamentally changes the landscape of visual storytelling, making it a truly immersive adventure for audiences. With Odyssey-2, the possibilities for interactive narratives are virtually limitless, inviting users to explore and create in ways they never thought possible.
