Gemma 4 26B A4B

gemma-4-26b-a4b-it

Gemma 4 31B is Google DeepMind’s most capable dense model in the Gemma 4 family, designed for advanced reasoning, coding, multimodal understanding, and agentic workflows. With 30.7 billion parameters and a context window of up to 256K tokens, it can process both text and images while handling complex, long-context tasks. The model also supports native function calling and more than 140 languages, making it a strong choice for coding assistants, intelligent agents, document analysis, and demanding general-purpose AI applications.

Model Highlights

Sparse computation, long context, and visual understanding.

Sparse Expert Efficiency

Uses 25.2B total parameters with 3.8B active per token, reducing active computation relative to the dense 31B variant.

Long Context Reasoning

Combines a 256K-token context window with configurable thinking for tasks involving substantial supplied material.

Multimodal Understanding

Processes text and images together and generates text, extending the MoE model to visual reasoning workloads.

Use Cases

Practical assistant workloads with an emphasis on inference efficiency.

Interactive Coding

Build coding assistants that explain source files, draft changes, and iterate on developer feedback.

Document Questions

Answer questions, summarize sections, and compare information across supplied manuals, reports, or retrieved passages.

Image-Grounded Assistance

Combine user questions with screenshots or document images to explain visible content and draft useful responses.

FAQs

Architecture, suitable workloads, and TokenHub usage.

What does A4B mean?+

This instruction-tuned Google DeepMind model uses a mixture-of-experts architecture: 25.2B total parameters and 3.8B active per token, rounded to about 4B in its name. Its open weights use Apache 2.0.

Which tasks benefit from this architecture?+

Interactive assistants, coding support, document questions, and image analysis are suitable uses. Sparse expert activation makes it an efficiency-focused option, while actual speed depends on hardware and serving software.

What limitations and memory costs should I expect?+

Active parameters do not equal total memory requirements: weights and context caches still need storage. This variant accepts text and images, not native audio, and generates text. Review outputs for errors.

How can I access it through TokenHub, and is it free?+

Check your TokenHub account for availability, the exact model ID, endpoint, and current rates before integration. Use the documented credentials and request format. The Apache 2.0 license does not guarantee free API access.

When should I choose this over the dense variant?+

Start with it when inference efficiency and responsiveness are priorities. Compare against the dense 31B variant on your own reasoning and coding tasks; lower active computation does not guarantee equal quality or lower provider pricing.
