OpenRouter Confirms Hunter/Healer Alpha Models as MiMo V2 Variants

OpenRouter's previously unannounced Hunter Alpha and Healer Alpha models have been officially confirmed as MiMo V2 variants. The identification comes from a GitHub pull request that specifies the exact model configurations.

Model Specifications

According to the source material:

• Hunter Alpha = MiMo V2 Pro Text-only Reasoning Model
  • Context Window: 1,048,576 tokens (1M)
  • Max Tokens: 32,000
• Healer Alpha = MiMo V2 Omni Text + Image Reasoning Model
  • Context Window: 262,144 tokens (262K)
  • Max Tokens: 32,000

The MiMo (Mixture of Mixtures) architecture represents a specific approach to model design that combines multiple specialized components. The V2 Pro designation indicates this is the second version of the text-only reasoning variant, while V2 Omni suggests a multimodal version capable of processing both text and images.

For context, OpenRouter operates as an API aggregator that provides access to multiple AI models through a unified interface. The platform typically lists available models with their specifications, pricing, and performance metrics. The 1M context window on Hunter Alpha is particularly notable as it approaches the practical limits of current transformer-based architectures, potentially enabling processing of very long documents or conversations.

The source also mentions that "a new model is coming," though no details about this upcoming release are provided in the extracted text.
