About Gemma 4 31B
Gemma 4 31B is a large language model developed by Google. It's particularly well-suited for analyzing images, screenshots, and visual content, orchestrating tool-using agents that call APIs and external services, producing structured outputs for reliable data extraction, and handling large contexts of up to 256K tokens. Its 256K-token context window means you can pass in entire documents, codebases, or conversation histories without losing context. Developers choose Gemma 4 31B when they need reliable, production-quality AI inference through a simple API — and on Qubax, it's available at a fraction of the cost of traditional providers.
In the broader AI landscape, Gemma 4 31B sits among the frontier-tier offerings from Google With multimodal vision and agentic tool use, it competes with the most frontier-tier models on the market. What sets it apart on Qubax isn't just the model itself — it's the accessibility. Rather than dealing with enterprise contracts or traditional payment rails, you get instant access via an OpenAI-compatible endpoint. That means you can drop Gemma 4 31B into Cursor, Cline, LangChain, or any framework that speaks the OpenAI protocol and start building immediately.
Qubax offers Gemma 4 31B at 97% below OpenRouter's price — just $0.0042 per million input tokens and $0.012 per million output tokens.
