Open WeightModel weights are publicly available — can be downloaded and self-hosted

Released August 2026131K context≈ 98,304 words

A compact open-weight model from CMSManhattan with a generous 131K token context window, which is notably large for a 7B parameter model. It handles text-in, text-out tasks and is available in both GGUF and safetensors formats, making it accessible for local deployment and fine-tuning workflows. Details about its specific strengths or specialty areas are limited beyond its architecture.

Glossary

ArchitectureThe underlying structural design of a neural network that defines how data flows through layers and components.Context WindowThe maximum number of tokens a model can process in a single conversation or prompt.Fine-TuningThe process of further training a pre-trained model on new data to adapt it for specific tasks or domains.GGUFA file format for quantized models designed for efficient CPU and GPU inference with llama.cpp.Local DeploymentRunning a model directly on your own computer or server instead of sending requests to a remote service.Open-Weight ModelA model whose trained weights are publicly released, allowing anyone to download and run it locally.Parameter ModelA neural network described by the number of learnable weights it contains; more parameters generally mean greater capacity to learn complex patterns, but also require more computational resources.SafetensorsA safe, fast file format for storing model weights, designed to prevent code execution vulnerabilities.Text-In, Text-OutA model that accepts text as input and produces text as output, without support for images, audio, or other data types.TokenA small unit of text (a word, subword, or punctuation mark) that a language model breaks input into for processing.
