overmind 0.1.39

Python client for Overmind API

Overmind SDK

Automatic observability for LLM applications. One call to init() instruments your existing OpenAI, Anthropic, Google Gemini, or Agno code — no proxy, no key sharing, no import changes.

Features

• Zero-change instrumentation: Keep using your existing LLM clients as-is
• Auto-detection: Detects installed providers automatically, or specify them explicitly
• Custom spans: Add your own tracing spans alongside LLM calls
• User & tag context: Tag traces with user IDs, custom attributes, and exceptions
• OpenTelemetry native: Built on standard OTLP — works with any OTel-compatible backend

Installation

pip install overmind

Install alongside your LLM provider package:

pip install overmind openai          # OpenAI
pip install overmind anthropic       # Anthropic
pip install overmind google-genai    # Google Gemini
pip install overmind agno            # Agno

Quick Start

1. Get your API key

Sign up at console.overmindlab.ai — your API key is shown immediately after signup.

2. Initialize the SDK

Call init() once at application startup, before any LLM calls:

from overmind import init

init(
    overmind_api_key="ovr_...",    # or set OVERMIND_API_KEY env var
    service_name="my-service",
    environment="production",
)

That's it. Your existing LLM code works unchanged and every call is automatically traced.

3. Use your LLM client as normal

from openai import OpenAI

client = OpenAI()  # your existing client, unchanged

response = client.chat.completions.create(
    model="gpt-5-mini",
    messages=[{"role": "user", "content": "Explain quantum computing"}],
)
print(response.choices[0].message.content)

Traces appear in your Overmind dashboard in real time.

Provider Examples

OpenAI

from overmind import init
from openai import OpenAI

init(service_name="my-service", providers=["openai"])

client = OpenAI()
response = client.chat.completions.create(
    model="gpt-5",
    messages=[{"role": "user", "content": "Hello!"}],
)

Anthropic

from overmind import init
import anthropic

init(service_name="my-service", providers=["anthropic"])

client = anthropic.Anthropic()
message = client.messages.create(
    model="claude-opus-4-5",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello!"}],
)

Google Gemini

from overmind import init
from google import genai

init(service_name="my-service", providers=["google"])

client = genai.Client()
response = client.models.generate_content(
    model="gemini-2.0-flash",
    contents="Explain quantum computing",
)

Agno

from overmind import init
from agno.agent import Agent
from agno.models.openai import OpenAIChat

init(service_name="my-service", providers=["agno"])

agent = Agent(model=OpenAIChat(id="gpt-5"), markdown=True)
agent.print_response("Write a short poem about the sea.")

Auto-detect all installed providers

Pass an empty providers list (or omit it) to automatically instrument every supported provider that is installed:

from overmind import init

init(service_name="my-service")  # auto-detects openai, anthropic, google, agno

Configuration

init() parameters

Parameter	Type	Default	Description
overmind_api_key	str | None	None	Your Overmind API key. Falls back to OVERMIND_API_KEY env var.
service_name	str | None	None	Name of your service (shown in traces). Also reads OVERMIND_SERVICE_NAME. Defaults to "unknown-service".
environment	str | None	None	Deployment environment ("production", "staging", etc.). Also reads OVERMIND_ENVIRONMENT. Defaults to "development".
providers	list[str] | None	None	Providers to instrument. Supported: "openai", "anthropic", "google", "agno". None or empty = auto-detect.
overmind_base_url	str | None	None	Override the Overmind API URL. Falls back to OVERMIND_API_URL env var, then https://api.overmindlab.ai.

Environment variables

Variable	Description
OVERMIND_API_KEY	Your Overmind API key
OVERMIND_SERVICE_NAME	Service name (overridden by service_name param)
OVERMIND_ENVIRONMENT	Environment name (overridden by environment param)
OVERMIND_API_URL	Custom API endpoint URL

Additional SDK Functions

get_tracer()

Get the OpenTelemetry tracer to create custom spans around any block of code:

from overmind import init, get_tracer

init(service_name="my-service")

tracer = get_tracer()

with tracer.start_as_current_span("process-document") as span:
    span.set_attribute("document.id", doc_id)
    result = process(doc)

set_user()

Tag the current trace with user identity. Call this in your request handler or middleware:

from overmind import set_user

# In a FastAPI middleware:
@app.middleware("http")
async def add_user_context(request: Request, call_next):
    if request.state.user:
        set_user(
            user_id=request.state.user.id,
            email=request.state.user.email,
        )
    return await call_next(request)

Parameter	Required	Description
user_id	Yes	Unique identifier for the user
email	No	User's email address
username	No	User's display name

set_tag()

Add a custom attribute to the current span:

from overmind import set_tag

set_tag("feature.flag", "new-checkout-flow")
set_tag("tenant.id", tenant_id)

capture_exception()

Record an exception on the current span and mark it as an error:

from overmind import capture_exception

try:
    result = risky_llm_call()
except Exception as e:
    capture_exception(e)
    raise

Full Example

import os
from overmind import init, get_tracer, set_user, set_tag, capture_exception
from openai import OpenAI

os.environ["OVERMIND_API_KEY"] = "ovr_your_key_here"

init(
    service_name="customer-support",
    environment="production",
    providers=["openai"],
)

client = OpenAI()

def handle_query(user_id: str, question: str) -> str:
    set_user(user_id=user_id)
    set_tag("workflow", "support")

    tracer = get_tracer()
    with tracer.start_as_current_span("handle-support-query"):
        try:
            response = client.chat.completions.create(
                model="gpt-5-mini",
                messages=[
                    {"role": "system", "content": "You are a helpful customer support agent."},
                    {"role": "user", "content": question},
                ],
            )
            return response.choices[0].message.content
        except Exception as e:
            capture_exception(e)
            raise

answer = handle_query("user-123", "How do I reset my password?")
print(answer)

What Happens After Your First Traces

Once Overmind has collected 10+ traces for a given prompt pattern, the optimization engine starts automatically:

1. Agent detection — extracts prompt templates from your traces
2. LLM judge scoring — evaluates each trace against auto-generated quality criteria
3. Prompt experimentation — generates and tests candidate prompt variations
4. Model backtesting — replays traces through alternative models to find cost/quality tradeoffs
5. Suggestions — surfaces the best alternatives in your dashboard

See How Optimization Works for details.
