Mixture-of-experts VLM delivering 97% of 31B quality at 8x less compute
google/gemma-4-26B-A4B-itmixpeek://image_extractor@v1/google_gemma4_26b_a4b_v1Overview
Gemma 4 27B-A4B is Google's MoE vision-language model that activates only 4B parameters per token from a total of 26B. It ranked #6 on the Arena AI leaderboard at launch while using a fraction of the compute of dense models its size.
The model handles both text and image input with a 256K context window, making it suitable for long-document visual understanding. Its efficiency profile makes it the best choice when you need high-quality VLM capabilities at manageable cost.
Architecture
Mixture-of-Experts architecture with 26B total parameters, 4B active per token. Vision encoder processes image patches alongside text tokens. 256K context window. Supports optional 'thinking' mode for chain-of-thought reasoning.
Mixpeek SDK Integration
// No extractor parameter takes a Hugging Face model id (checked against
// GET /v1/discovery/extractors, which returns 13), so gemma-4-26B-A4B-it runs
// on your side and the output is upserted through POST
// /v1/namespaces/{namespace_id}/documents/upsert. On Enterprise the other
// path is to upload the weights instead: POST /v1/namespaces/{id}/models
// accepts the huggingface format and a custom plugin loads them.
