Gemma 3 12B vs Grok 4

Gemma 3 12B

Google DeepMind

Gemma 3 12B is a 12-billion-parameter open-weight model from Google DeepMind, released in March 2025 as part of the Gemma 3 series designed to bring multimodal reasoning to accessible hardware. The model supports both text and image inputs across a 128K token context window, extending the vision capabilities that defined the Gemma 3 generation compared to earlier text-only Gemma releases. It became widely adopted for domain-specific fine-tuning in research and enterprise settings where full multimodal capability was needed without the infrastructure demands of larger frontier models.

Grok 4

xAI

Grok 4, released by xAI on July 10, 2025, is a large language model featuring first-principles reasoning and comprehensive multimodal support. It features a 260K token context window and demonstrated strong performance on advanced reasoning and coding benchmarks. Grok 4 targets complex multi-step reasoning tasks, scientific analysis, and agentic workflows via the xAI API.
