Anthropic Claude¶

v3¶

Class: AnthropicClaudeBlockV3 (there are multiple versions of this block)

Source: inference.core.workflows.core_steps.models.foundation.anthropic_claude.v3.AnthropicClaudeBlockV3

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 Anthropic Claude 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
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 Key Options¶

This block supports two API key modes:

Roboflow Managed API Key (Default) - Use rf_key:account to proxy requests through Roboflow's API:
Simplified setup - no Anthropic API key required
Secure - your workflow API key is used for authentication
Usage-based billing - charged per token based on the model used
Custom Anthropic API Key - Provide your own Anthropic API key:
Full control over API usage
You pay Anthropic directly

Type identifier¶

Use the following identifier in step "type" field: roboflow_core/anthropic_claude@v3to 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 Claude 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 Anthropic API key or 'rf_key:account' to use Roboflow's managed API key.	✅
`model_version`	`str`	Model to be used.	✅
`extended_thinking`	`bool`	Enable extended thinking for deeper reasoning on complex tasks. Note: temperature cannot be used when extended thinking is enabled..	❌
`thinking_budget_tokens`	`int`	Maximum number of tokens for internal thinking when extended thinking is enabled. Higher values allow deeper reasoning but increase latency and cost. Must be less than max_tokens. Minimum: 1024..	❌
`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 0.0-1.0, the higher - the more random / "creative" the generations are. Cannot be used when extended_thinking is enabled..	✅
`max_image_size`	`int`	Maximum size of the image - if input has larger side, it will be downscaled, keeping aspect ratio.	✅
`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 Anthropic API limits..	❌

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