Gemma 3 27B
v2025-01Google's open-source Gemma 3 model with 27 billion parameters, now superseded by Gemma 4 (released 2026-04-02 under Apache 2.0, a license improvement over the custom Gemma license). Was designed for developers seeking Google's research quality with open-source flexibility; new deployments should evaluate Gemma 4 instead.

Use Case Ratings
code generation
Basic coding capabilities. 128K context handles mid-size codebases, but accuracy limits complex projects.
customer support
Adequate for basic customer support with privacy benefits.
content creation
Good for short-form content; 128K context also permits long-form drafting.
data analysis
Basic data analysis only. Not suitable for complex tasks.
research assistant
Basic research tasks. 42.4% MMLU shows limited knowledge depth.
legal compliance
Basic legal tasks with data sovereignty. Limited accuracy for complex work.
healthcare
Basic healthcare tasks with self-hosted HIPAA compliance.
financial analysis
Basic financial tasks only. Not suitable for complex modeling.
education
Good for basic educational content and tutoring.
creative writing
Adequate for creative writing; 128K context supports long-form, though quality trails frontier models.
