What to know about diffusiongemma 26B A4B it
AI-compiled from linked model documentation. This is a catalog reference, not an independent performance review. Catalog checked October 23, 2026.
Which diffusiongemma 26B A4B it does this page describe?
diffusiongemma 26B A4B it is a model record from Google in the diffusiongemma family. Source
The recorded model identifier or checkpoint is google/diffusiongemma-26B-A4B-it. Use that exact identifier when checking documentation or a provider listing. Source
How can you access diffusiongemma 26B A4B it?
The catalog documents Open weights access for diffusiongemma 26B A4B it. Source
As of the catalog check, this version was listed as available. Source
Open weights means the model weights are distributed for use under their stated terms. It does not establish a hosted API, an open-source license, or a hardware requirement.
What are diffusiongemma 26B A4B it's context and output limits?
The documented context window is 256,000 tokens. Source
A separate maximum-output value is not established in this record. The context or input figure should not be used as an output allowance.
Context, input and output limits describe different constraints. Do not add the figures together to infer a larger window. Check the endpoint's accounting for conversation history, system instructions, tools, media and generated tokens; a documented maximum is not a guarantee of answer quality or a measured usable capacity.
What dates are documented for diffusiongemma 26B A4B it?
Training-data cutoff: January 2025. Source This describes the reported data boundary, not the day training finished. The source labels this “Pre-training dataset cutoff.”
Retrieval or web tools can supply newer information at run time. That does not change the model's recorded training or knowledge dates, and this record does not establish that a particular endpoint includes those tools.
What can diffusiongemma 26B A4B it receive and generate?
Documented inputs: text, image, and video. Source
Documented outputs: text. Source
Input support and output generation are separate capabilities. Reading an image does not establish image generation; a text output listing does not establish speech output. File sizes, formats and media limits depend on the documented implementation.
What license is recorded for diffusiongemma 26B A4B it?
The recorded license label is Apache-2.0. Source
Read the linked license and associated use terms for this exact version before redistribution, commercial deployment or fine-tuning. A label alone does not establish every permission, restriction or obligation, and it does not determine the terms of a separate hosted service.
What is documented about the diffusiongemma 26B A4B it checkpoint?
This evidence refers to google/diffusiongemma-26B-A4B-it at recorded revision f7f5b7f5fa82ffc52addd066915886d497f5517b, checked October 23, 2026. Repository metadata
Safetensors metadata records 25,823,778,864 stored parameters. This is a stored-weight count, not necessarily the number activated per token, a download size or a GPU-memory requirement. Repository metadata
Recorded architecture class: DiffusionGemmaForBlockDiffusion. Repository metadata
Repository task tag: image-text-to-text. A task tag identifies a distribution category; it does not measure performance on that task. Repository metadata
Listed library: transformers. Check that library's version and model support before loading the weights. Repository metadata
Repository access gate: false. This records the repository's gate setting when checked; licensing and use terms still apply. Repository metadata
What the configuration file says
The pinned config.json section text_config contains these values. Pinned configuration
max_position_embeddings- 262,144
sliding_window- 1,024
torch_dtype- bfloat16
num_attention_heads- 16
num_key_value_heads- 8
num_hidden_layers- 30
hidden_size- 2,816
Configuration values describe the checkpoint and its implementation. In particular, max_position_embeddings, sliding_window and rope_scaling do not independently establish an API context limit, tested usable length or hardware requirement. Runtime, quantization, cache, batch size and input length affect deployment behavior.

The documented record
Specifications, with their sources.
A missing value remains unknown. Input limits, output limits and the total context window are separate measurements.

Read this with the numbers.
Official Google-published checkpoint. Base/pretrained and instruction-tuned variants remain distinct; platform and quantized packaging copies are excluded. Hosted API availability not inferred. Publisher repository evidence (2026-10-23): Publisher task label: image-text-to-text. Published architecture metadata: DiffusionGemmaForBlockDiffusion. Repository library label: transformers. Published safetensors metadata counts 25,823,778,864 stored parameters; this is not an active-parameter count for mixture-of-experts models. Published text_config configuration: max_position_embeddings=262144; sliding_window=1024; dtype=bfloat16; 30 hidden layers. Checkpoint configuration is not a verified hosted serving limit; context and output limits remain separate documented fields.
