Llama 3.2 Vision¶

v2¶

Class: LlamaVisionBlockV2 (there are multiple versions of this block)

Source: inference.core.workflows.core_steps.models.foundation.llama_vision.v2.LlamaVisionBlockV2

Warning: This block has multiple versions. Please refer to the specific version for details. You can learn more about how versions work here: Versioning

Ask a question to Llama 3.2 Vision model.

You can specify arbitrary text prompts or predefined ones, the block supports the following types of prompt:

Open Prompt (unconstrained) - Use any prompt to generate a raw response
Text Recognition (OCR) (ocr) - Model recognizes text in the image
Visual Question Answering (visual-question-answering) - Model answers the question you submit in the prompt
Captioning (short) (caption) - Model provides a short description of the image
Captioning (detailed-caption) - Model provides a long description of the image
Single-Label Classification (classification) - Model classifies the image content as one of the provided classes
Multi-Label Classification (multi-label-classification) - Model classifies the image content as one or more of the provided classes
Unprompted Object Detection (object-detection) - Model detects and returns the bounding boxes for prominent objects in the image
Structured Output Generation (structured-answering) - Model returns a JSON response with the specified fields

🛠️ API providers and model variants¶

Llama 3.2 Vision is exposed via OpenRouter. By default this block uses the Roboflow-managed OpenRouter key and bills your Roboflow credits — no extra setup needed. To bypass Roboflow billing, paste your own sk-or-... key into the api_key field.

The privacy_level field controls which OpenRouter providers may serve the request:

No data collection (default) – providers may not train on your inputs.
Allow data collection – broader provider pool.
Zero data retention – strictest, restricts to providers that retain nothing.

Type identifier¶

Use the following identifier in step "type" field: roboflow_core/llama_vision@v2to add the block as as step in your workflow.

Properties¶

Name	Type	Description	Refs
`name`	`str`	Enter a unique identifier for this step..	❌
`api_key`	`str`	OpenRouter API key. Defaults to Roboflow's managed key, billed in credits via Roboflow. Provide your own `sk-or-...` key to call OpenRouter directly without Roboflow billing..	✅
`privacy_level`	`str`	Provider privacy filter. Stricter levels reduce the pool of providers and may increase per-call cost on the managed key..	❌
`max_tokens`	`int`	Maximum number of tokens the model can generate in its response..	❌
`temperature`	`float`	Temperature to sample from the model - value in range 0.0-2.0, the higher - the more random / "creative" the generations are..	✅
`max_concurrent_requests`	`int`	Number of concurrent requests for batches of images. If not given - block defaults to value configured globally in Workflows Execution Engine. Restrict if you hit rate limits..	❌
`task_type`	`str`	Task type to be performed by model. Value determines required parameters and output response..	❌
`prompt`	`str`	Text prompt to the Llama model.	✅
`output_structure`	`Dict[str, str]`	Dictionary with structure of expected JSON response.	❌
`classes`	`List[str]`	List of classes to be used.	✅
`model_version`	`str`	Model to be used.	✅

The Refs column marks possibility to parametrise the property with dynamic values available in workflow runtime. See Bindings for more info.

v1¶

Class: LlamaVisionBlockV1 (there are multiple versions of this block)

Warning: This block has multiple versions. Please refer to the specific version for details. You can learn more about how versions work here: Versioning

Ask a question to Llama 3.2 Vision model with vision capabilities.

You can specify arbitrary text prompts or predefined ones, the block supports the following types of prompt:

Open Prompt (unconstrained) - Use any prompt to generate a raw response
Text Recognition (OCR) (ocr) - Model recognizes text in the image
Visual Question Answering (visual-question-answering) - Model answers the question you submit in the prompt
Captioning (short) (caption) - Model provides a short description of the image
Captioning (detailed-caption) - Model provides a long description of the image
Single-Label Classification (classification) - Model classifies the image content as one of the provided classes
Multi-Label Classification (multi-label-classification) - Model classifies the image content as one or more of the provided classes
Structured Output Generation (structured-answering) - Model returns a JSON response with the specified fields

Issues with structured prompting

Model tends to be quite unpredictable when structured output (in our case JSON document) is expected. That problems may impact tasks like structured-answering, classification or multi-label-classification.

The cause seems to be quite sensitive "filters" of inappropriate content embedded in model.

🛠️ API providers and model variants¶

Llama Vision 3.2 model is exposed via OpenRouter API and we require passing OpenRouter API Key to run.

There are different versions of the model supported:

smaller version (11B) is faster and cheaper, yet you can expect better quality of results using 90B version
Regular version is paid (and usually faster) API, whereas Free is free for use for OpenRouter clients (state at 01.01.2025)

As for now, OpenRouter is the only provider for Llama 3.2 Vision model, but we will keep you posted if the state of the matter changes.

API Usage Charges

OpenRouter is external third party providing access to the model and incurring charges on the usage. Please check out pricing before use:
