## haystack_integrations.components.generators.anthropic.chat.chat_generator

### AnthropicChatGenerator

Completes chats using Anthropic's large language models (LLMs).

It uses [ChatMessage](https://docs.haystack.deepset.ai/docs/data-classes#chatmessage)
format in input and output. Supports multimodal inputs including text and images.

You can customize how the text is generated by passing parameters to the
Anthropic API. Use the `**generation_kwargs` argument when you initialize
the component or when you run it. Any parameter that works with
`anthropic.Message.create` will work here too.

For details on Anthropic API parameters, see
[Anthropic documentation](https://docs.anthropic.com/en/api/messages).

Usage example:

```python
from haystack_integrations.components.generators.anthropic import (
    AnthropicChatGenerator,
)
from haystack.dataclasses import ChatMessage

generator = AnthropicChatGenerator(
    generation_kwargs={
        "max_tokens": 1000,
        "temperature": 0.7,
    },
)

messages = [
    ChatMessage.from_system(
        "You are a helpful, respectful and honest assistant"
    ),
    ChatMessage.from_user("What's Natural Language Processing?"),
]
print(generator.run(messages=messages))
```

Usage example with images:

```python
from haystack.dataclasses import ChatMessage, ImageContent

image_content = ImageContent.from_file_path("path/to/image.jpg")
messages = [
    ChatMessage.from_user(
        content_parts=["What's in this image?", image_content]
    )
]
generator = AnthropicChatGenerator()
result = generator.run(messages)
```

#### __init__

```python
__init__(
    api_key: Secret = Secret.from_env_var("ANTHROPIC_API_KEY"),
    model: str = "claude-sonnet-4-5",
    streaming_callback: StreamingCallbackT | None = None,
    generation_kwargs: dict[str, Any] | None = None,
    ignore_tools_thinking_messages: bool = True,
    tools: ToolsType | None = None,
    *,
    timeout: float | None = None,
    max_retries: int | None = None
) -> None
```

Creates an instance of AnthropicChatGenerator.

**Parameters:**

- **api_key** (<code>Secret</code>) – The Anthropic API key
- **model** (<code>str</code>) – The name of the model to use.
- **streaming_callback** (<code>StreamingCallbackT | None</code>) – A callback function that is called when a new token is received from the stream.
  The callback function accepts StreamingChunk as an argument.
- **generation_kwargs** (<code>dict\[str, Any\] | None</code>) – Other parameters to use for the model. These parameters are all sent directly to
  the Anthropic endpoint. See Anthropic [documentation](https://docs.anthropic.com/claude/reference/messages_post)
  for more details.

Supported generation_kwargs parameters are:

- `system`: The system message to be passed to the model.
- `max_tokens`: The maximum number of tokens to generate.
- `metadata`: A dictionary of metadata to be passed to the model.
- `stop_sequences`: A list of strings that the model should stop generating at.
- `temperature`: The temperature to use for sampling.
- `top_p`: The top_p value to use for nucleus sampling.
- `top_k`: The top_k value to use for top-k sampling.
- `extra_headers`: A dictionary of extra headers to be passed to the model (i.e. for beta features).
- `thinking`: A dictionary of thinking parameters to be passed to the model.
  The `budget_tokens` passed for thinking should be less than `max_tokens`.
  For more details and supported models, see: [Anthropic Extended Thinking](https://docs.anthropic.com/en/docs/build-with-claude/extended-thinking)
- `output_config`: A dictionary of output configuration options to be passed to the model.
- **ignore_tools_thinking_messages** (<code>bool</code>) – Anthropic's approach to tools (function calling) resolution involves a
  "chain of thought" messages before returning the actual function names and parameters in a message. If
  `ignore_tools_thinking_messages` is `True`, the generator will drop so-called thinking messages when tool
  use is detected. See the Anthropic [tools](https://docs.anthropic.com/en/docs/tool-use#chain-of-thought-tool-use)
  for more details.
- **tools** (<code>ToolsType | None</code>) – A list of Tool and/or Toolset objects, or a single Toolset, that the model can use.
  Each tool should have a unique name.
- **timeout** (<code>float | None</code>) – Timeout for Anthropic client calls. If not set, it defaults to the default set by the Anthropic client.
- **max_retries** (<code>int | None</code>) – Maximum number of retries to attempt for failed requests. If not set, it defaults to the default set by

client = AnthropicGenerator(model="claude-sonnet-4-20250514")
response = client.run("What's Natural Language Processing? Be brief.")
print(response)
>>{'replies': ['Natural language processing (NLP) is a branch of artificial intelligence focused on enabling
>>computers to understand, interpret, and manipulate human language. The goal of NLP is to read, decipher,
>> understand, and make sense of the human languages in a manner that is valuable.'], 'meta': {'model':
