| 5 | +## What are Evals? |
| 6 | + |
| 7 | +**Evals** are like tests for your Agents. Use them judiciously to evaluate the performance of your Agents and improve them over time. |
| 8 | + |
| 9 | +We typically evaludate Agents on 3 dimensions: |
| 10 | + |
| 11 | +- **Accuracy:** How accurate is the Agent's response? |
| 12 | +- **Performance:** How fast does the Agent produce the output and what is the memory footprint? |
| 13 | +- **Reliability:** Does the Agent make the expected tool calls? |
| 14 | + |
| 15 | +### Accuracy |
| 16 | + |
| 17 | +Accuracy evals use input/output pairs to evaluate the Agent's performance. They use another model to score the Agent's responses (LLM-as-a-judge). |
| 18 | + |
| 19 | +#### Example |
| 20 | + |
| 21 | +```python calculate_accuracy.py |
| 22 | +from typing import Optional |
| 23 | + |
| 24 | +from agno.agent import Agent |
| 25 | +from agno.eval.accuracy import AccuracyEval, AccuracyResult |
| 26 | +from agno.models.openai import OpenAIChat |
| 27 | +from agno.tools.calculator import CalculatorTools |
| 28 | + |
| 29 | + |
| 30 | +def multiply_and_exponentiate(): |
| 31 | + evaluation = AccuracyEval( |
| 32 | + agent=Agent( |
| 33 | + model=OpenAIChat(id="gpt-4o-mini"), |
| 34 | + tools=[CalculatorTools(add=True, multiply=True, exponentiate=True)], |
| 35 | + ), |
| 36 | + question="What is 10*5 then to the power of 2? do it step by step", |
| 37 | + expected_answer="2500", |
| 38 | + num_iterations=1 |
| 39 | + ) |
| 40 | + result: Optional[AccuracyResult] = evaluation.run(print_results=True) |
| 41 | + |
| 42 | + assert result is not None and result.avg_score >= 8 |
| 43 | + |
| 44 | + |
| 45 | +if __name__ == "__main__": |
| 46 | + multiply_and_exponentiate() |
| 47 | +``` |
| 48 | + |
| 49 | +### Performance |
| 50 | + |
| 51 | +Performance evals measure the latency and memory footprint of the Agent operations. |
| 52 | + |
| 53 | +<Note> |
| 54 | +While latency will be dominated by the model API response time, we should still keep performance top of mind and track the agent performance with and without certain components. Eg: it would be good to know what's the average latency with and without storage, memory, with a new prompt, or with a new model. |
| 55 | +</Note> |
| 56 | + |
| 57 | +#### Example |
| 58 | + |
| 59 | +```python storage_performance.py |
| 60 | +"""Run `pip install openai agno` to install dependencies.""" |
| 61 | + |
| 62 | +from agno.agent import Agent |
| 63 | +from agno.models.openai import OpenAIChat |
| 64 | +from agno.eval.perf import PerfEval |
| 65 | + |
| 66 | +def simple_response(): |
| 67 | + agent = Agent(model=OpenAIChat(id='gpt-4o-mini'), system_message='Be concise, reply with one sentence.', add_history_to_messages=True) |
| 68 | + response_1 = agent.run('What is the capital of France?') |
| 69 | + print(response_1.content) |
| 70 | + response_2 = agent.run('How many people live there?') |
| 71 | + print(response_2.content) |
| 72 | + return response_2.content |
| 73 | + |
| 74 | + |
| 75 | +simple_response_perf = PerfEval(func=simple_response, num_iterations=1, warmup_runs=0) |
| 76 | + |
| 77 | +if __name__ == "__main__": |
| 78 | + simple_response_perf.run(print_results=True) |
| 79 | +``` |
| 80 | + |
| 81 | +### Reliability |
| 82 | + |
| 83 | +What makes an Agent reliable? |
| 84 | + |
| 85 | +- Does the Agent make the expected tool calls? |
| 86 | +- Does the Agent handle errors gracefully? |
| 87 | +- Does the Agent respect the rate limits of the model API? |
| 88 | + |
| 89 | +#### Example |
| 90 | + |
| 91 | +The first check is to ensure the Agent makes the expected tool calls. Here's an example: |
| 92 | + |
| 93 | +```python reliability.py |
| 94 | +from typing import Optional |
| 95 | + |
| 96 | +from agno.agent import Agent |
| 97 | +from agno.eval.reliability import ReliabilityEval, ReliabilityResult |
| 98 | +from agno.tools.calculator import CalculatorTools |
| 99 | +from agno.models.openai import OpenAIChat |
| 100 | +from agno.run.response import RunResponse |
| 101 | + |
| 102 | + |
| 103 | +def multiply_and_exponentiate(): |
| 104 | + |
| 105 | + agent=Agent( |
| 106 | + model=OpenAIChat(id="gpt-4o-mini"), |
| 107 | + tools=[CalculatorTools(add=True, multiply=True, exponentiate=True)], |
| 108 | + ) |
| 109 | + response: RunResponse = agent.run("What is 10*5 then to the power of 2? do it step by step") |
| 110 | + evaluation = ReliabilityEval( |
| 111 | + agent_response=response, |
| 112 | + expected_tool_calls=["multiply", "exponentiate"], |
| 113 | + ) |
| 114 | + result: Optional[ReliabilityResult] = evaluation.run(print_results=True) |
| 115 | + result.assert_passed() |
| 116 | + |
| 117 | + |
| 118 | +if __name__ == "__main__": |
| 119 | + multiply_and_exponentiate() |
| 120 | +``` |
| 121 | + |
| 122 | +<Note> |
| 123 | +Reliability evals are currently in `beta`. |
