# Quickstart

> Install the Agent Optimizer SDK, run your first optimization, and inspect the results in under 10 minutes.

**Opik Agent Optimizer Quickstart** gives you the fastest path from “hello world” to a successful optimization run. If you already walked through the main [Opik Quickstart](/quickstart) (tracing + evaluation), this is the next stop—it layers on the `opik-optimizer` SDK so you can automatically improve prompts and agents. Prefer a UI workflow? Use [Optimization Studio](/agent_optimization/optimization_studio) instead.

## Why Opik Agent Optimizer?

* **Production-grade workflows** – reuse the same datasets, metrics, and tracing you already have in Opik.
* **Multiple strategies** – swap between MetaPrompt, Hierarchical Reflective Prompt Optimizer (HRPO), Evolutionary, GEPA, and more with one API.
* **Deep analysis** – every trial is logged to Opik so you can inspect prompts, tool calls, and failure modes.

  Estimated time: **≤10 minutes** if you already have Python and an Opik API key configured.
</Callout>

## Prerequisites

* Python 3.10+
* Opik account
* Access to an OpenAI-compatible LLM via LiteLLM (`OPENAI_API_KEY`, `ANTHROPIC_API_KEY`, etc.)

## 1. Install and authenticate

```bash
pip install --upgrade opik opik-optimizer
opik configure  # paste your API key
```

## 2. Create a dataset and metric

```python
import opik
from opik.evaluation.metrics import LevenshteinRatio

client = opik.Opik()
dataset = client.get_or_create_dataset(name="agent-opt-quickstart")
dataset.insert([
    {"question": "What is Opik?", "answer": "Opik is an LLM observability and optimization platform."},
    {"question": "How do I reduce hallucinations?", "answer": "Use evaluations and prompt optimization to enforce grounding."},
])

def answer_quality(item, output):
    metric = LevenshteinRatio()
    return metric.score(reference=item["answer"], output=output)
```

## 3. Run the optimizer

```python
from opik_optimizer import MetaPromptOptimizer, ChatPrompt

prompt = ChatPrompt(
    messages=[
        {"role": "system", "content": "You are a precise assistant."},
        {"role": "user", "content": "{question}"},
    ],
    model="openai/gpt-4o-mini"  # The model your prompt runs on
)

optimizer = MetaPromptOptimizer(model="openai/gpt-4o")  # The model that improves your prompt
result = optimizer.optimize_prompt(
    prompt=prompt,
    dataset=dataset,
    metric=answer_quality,
    max_trials=3,
    n_samples=2,
)

result.display()
```

<Tip>
  **Using a different LLM provider?** The optimizer supports OpenAI, Anthropic, Gemini, Azure, Ollama, and 100+ other providers via LiteLLM. See the [Configure LLM Providers](/agent_optimization/optimization/configure_models) guide for setup instructions.
</Tip>

## 4. Inspect results

* Run `opik dashboard` or open [https://www.comet.com/opik](https://www.comet.com/opik).
* In the left nav, go to **Evaluation → Optimization runs**, then select your latest run.
* Review the optimization-progress chart, trial table, and per-trial traces to decide whether to ship the new prompt.

## Common first issues

<AccordionGroup>
  <Accordion title="Prompt must be a ChatPrompt object">
    Import `ChatPrompt` from `opik_optimizer` and wrap your `messages` list before passing it to any optimizer.
  </Accordion>

  <Accordion title="Authentication failed">
    Re-run `opik configure` and confirm the account has Agent Optimizer access. If you changed machines, copy the `~/.opik/config` file or re-enter the key.
  </Accordion>

  <Accordion title="liteLLM provider errors">
    Ensure provider keys (e.g., `OPENAI_API_KEY`) are exported in the same shell running the script, and verify the model you selected is enabled for that key.
  </Accordion>
