Llama 3.2 Vision

Class: LlamaVisionBlockV1

Source: inference.core.workflows.core_steps.models.foundation.llama_vision.v1.LlamaVisionBlockV1

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:

Type identifier

Use the following identifier in step "type" field: roboflow_core/llama_3_2_vision@v1to add the block as as step in your workflow.

Properties

Name Type Description Refs
name str Enter a unique identifier for this step.. ❌
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. ✅
api_key str Your Llama Vision API key (dependent on provider, ex: OpenRouter API key). ✅
model_version str Model to be used. ✅
max_tokens int Maximum number of tokens the model can generate in it's 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 that can be executed by block when batch of input images provided. If not given - block defaults to value configured globally in Workflows Execution Engine. Please restrict if you hit limits.. ❌

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