PrismML Releases Bonsai 2 27B: A 5.9GB Local AI Model Based on Qwen
Executive TL;DR30s read

PrismML has introduced Bonsai 2 27B, a quantized model based on Qwen that occupies only 5.9 GB while retaining 98.2% of the original performance.

The PrismML team has introduced the new Bonsai 2 27B model, built on the Qwen3.8 27B architecture. This release demonstrates significant progress in the field of local models and resource optimization.

Thanks to 3-bit quantization, the model size has been reduced to 5.9 GB, which is approximately nine times smaller than the full version. This makes it ideal for running on devices with limited memory.

According to developer tests, the model retains 98.2% of the original model's results. At the same time, it supports image processing (multimodality) and tool calling (function calling).

The Bonsai 2 27B model is open and available under the Apache 2.0 license. The official announcement can be viewed on the PrismML website.
