G9v3-3B

G9v3-3B is a dense 3-billion parameter causal language model developed by the AI9Stars team. Released in July 2026, it is designed for local deployment and operation within resource-constrained environments. The model is released under an Apache 2.0 license, facilitating both personal and commercial use cases.

The model is built upon the Llama architecture (specifically LlamaForCausalLM) and is optimized for general assistant tasks, coding, and reasoning. One of its defining technical features is a large context window of 131,072 tokens, which enables the processing of extensive documents and long-form conversational history that typically requires much larger models.

In performance benchmarks, G9v3-3B is positioned as a high-intelligence model within the tiny-parameter class (models $\le$ 4B). While it is designed to deliver strong reasoning capabilities, AI9Stars recommends its use primarily as a general AI assistant. It has been noted for its ability to handle tool-use workflows and complex instructions despite its small footprint.

The development of G9v3-3B emphasizes a balance between speed and cognitive depth, aiming to provide a lightweight alternative for users who require frontier-like reasoning without the high hardware requirements of larger model families. It supports standard text-based modalities and is frequently used for local agentic tasks and copyediting.
