Released August 2025131K context≈ 98,304 words20b params

A compact open-weight model running in mixed-precision quantization (MXFP4 with Q8 weights), balancing memory efficiency with reasonable output quality. It handles general text tasks competently but reflects the trade-offs of aggressive quantization — slightly softer reasoning on complex multi-step problems compared to full-precision counterparts. Works well in resource-constrained local deployments where fitting the model into limited VRAM matters.

Glossary

Full-PrecisionA model using standard 32-bit floating-point numbers to represent weights, providing maximum accuracy but requiring more memory.MXFP4A low-precision floating-point format (4-bit) designed for efficient neural network computation while maintaining reasonable accuracy.Memory EfficiencyHow well a model uses available RAM or GPU memory, allowing it to run on smaller or less expensive hardware.Mixed-Precision QuantizationUsing different numerical precisions (e.g., 8-bit, 4-bit) for different parts of a model to reduce memory and computation.Open-Weight ModelA model whose trained weights are publicly released, allowing anyone to download and run it locally.PrecisionThe level of numerical detail a model uses to represent its internal values; higher precision means more accurate calculations but requires more memory.QuantizationReducing a model's numerical precision (e.g., from 16-bit to 4-bit) to shrink memory usage and speed up inference.ReasoningThe model's ability to work through multi-step logical problems and provide justified answers rather than just pattern-matching.Resource-ConstrainedHardware with limited memory, processing power, or battery life, requiring models to be optimized for efficiency.VRAMVideo RAM — the memory on a GPU that stores model weights and intermediate computations during inference.WeightsThe numerical parameters inside a neural network that determine how it processes input and generates output.
