+[Mirascope](https://github.com/Mirascope/mirascope) is an intuitive approach to building AI-powered applications using LLMs. Their library integrates with Logfire to make observability and monitoring for LLMs easy and seamless.
+
+You can enable it using their [`@with_logire`][mirascope-logfire] decorator, which will work with all of the [model providers that they support][mirascope-supported-providers] (e.g. OpenAI, Anthropic, Groq, and more).
+
+```py hl_lines="1 2 5 8"
+import logfire
+from mirascope.logfire import with_logfire
+from mirascope.anthropic import AnthropicCall
+
+logfire.configure()
+
+
+@with_logfire
+class BookRecommender(AnthropicCall):
+    prompt_template = "Please recommend some {genre} books"
+
+    genre: str
+
+
+recommender = BookRecommender(genre="fantasy")
+response = recommender.call()  # this will automatically get logged with logfire
+print(response.content)
+#> Here are some recommendations for great fantasy book series: ...
+```
+
+This will give you:
+
+* A span around the `AnthropicCall.call()` that captures items like the prompt template, templating properties and fields, and input/output attributes.
+* Human-readable display of the conversation with the agent
+* Details of the response, including the number of tokens used

+
+Since Mirascope is build on top of [Pydantic][pydantic], you can use the [Pydantic plugin][pydantic-plugin] to track additional logs and metrics about model validation, which you can enable using the [`pydantic_plugin`][logfire.configure(pydantic_plugin)] configuration.
+
+This can be particularly useful when [extracting structured information][mirascope-extracting-structured-information] using LLMs:
+
+```py hl_lines="3 4 8 17"
+from typing import Literal, Type
+
+import logfire
+from mirascope.logfire import with_logfire
+from mirascope.openai import OpenAIExtractor
+from pydantic import BaseModel
+
+logfire.configure(pydantic_plugin=logfire.PydanticPlugin(record="all"))
+
+
+class TaskDetails(BaseModel):
+    description: str
+    due_date: str
+    priority: Literal["low", "normal", "high"]
+
+
+@with_logfire
+class TaskExtractor(OpenAIExtractor[TaskDetails]):
+    extract_schema: Type[TaskDetails] = TaskDetails
+    prompt_template = """
+    Extract the task details from the following task:
+    {task}
+    """
+
+    task: str
+
+
+task = "Submit quarterly report by next Friday. Task is high priority."
+task_details = TaskExtractor(
+    task=task
+).extract()  # this will be logged automatically with logfire
+assert isinstance(task_details, TaskDetails)
+print(task_details)
+#> description='Submit quarterly report' due_date='next Friday' priority='high'
+```
+
+This will give you:
+
+* Tracking for validation of Pydantic models.
+* A span around the `OpenAIExtractor.extract()` that captures items like the prompt template, templating properties and fields, and input/output attributes.
+* Human-readable display of the conversation with the agent including the function call
+* Details of the response, including the number of tokens used
