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:

  1. Roboflow Managed API Key (Default) - Use rf_key:account to proxy requests through Roboflow's API:
  2. Simplified setup - no Anthropic API key required
  3. Secure - your workflow API key is used for authentication

  4. Usage-based billing - charged per token based on the model used

  5. Custom Anthropic API Key - Provide your own Anthropic API key:

  6. Full control over API usage
  7. 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.
