First off, welcome to the community, Anya! I’ll take this opportunity to document a new use case involving Mem0 integration with CrewAI.

**The Error:**

The earlier memory implementation using Mem0 had [a bug, which we discussed in this thread](https://community.crewai.com/t/mem0-integration-with-crew-ai/4951/5). So, yesterday, version `0.114.0` was released, along with [an example showcasing the new `ExternalMemory` usage](https://docs.crewai.com/concepts/memory#basic-usage-with-mem0). When I ran their example code, I got the following:

```bash
ValidationError: 1 validation error for Crew
  Value error, Please provide an OpenAI API key.

```

Great, we went from a buggy implementation (which required tricking the system) to a weird one (that has hidden dependencies). That’s progress, right? 😏

**Where the Error Comes From:**

Digging into [the `crewai/crew.py` file](https://github.com/crewAIInc/crewAI/blob/main/src/crewai/crew.py), particularly the `create_crew_memory` validator, I noticed that this flag initializes several internal memory components like `ShortTermMemory`, `LongTermMemory`, and `EntityMemory` — even if you only want to use `ExternalMemory`.

And these other memory components rely on embeddings. So, you’re forced to provide an `embedder` configuration in your Crew setup to keep those components happy. **Disclaimer:** Honestly, I haven’t double-checked if that embedder gets configured automatically when the `OPENAI_API_KEY` environment variable is set. Since I ran into the error above, I’m documenting it here just in case.

**Solution (Embedder Required for Other Memory Modules):**

Below you’ll find a working example using Gemini, which also remembers user information.

```python
from crewai import Agent, Task, Crew, LLM, Process
from crewai.memory.external.external_memory import ExternalMemory
import os

os.environ["MEM0_API_KEY"] = "YOUR-KEY"
os.environ["GEMINI_API_KEY"] = "YOUR-KEY"

gemini_llm = LLM(
    model='gemini/gemini-2.0-flash',
    temperature=0.5,
	max_tokens=1024
)

chatbot_agent = Agent(
    role="Friendly Chatbot",
    goal="Respond kindly to the user in a single paragraph.",
    backstory="A helpful AI assistant for brief interactions.",
    llm=gemini_llm,
    verbose=False,
    allow_delegation=False
)

chat_task = Task(
    description=(
        "Process the user query: '{user_question}' "
        "and provide a friendly response."
    ),
    expected_output="A single paragraph, friendly response.",
    agent=chatbot_agent
)

crew = Crew(
    agents=[chatbot_agent],
    tasks=[chat_task],
    verbose=False,
    process=Process.sequential,
    memory=True,
    embedder={
        "provider": "google",
        "config": {
            "model": "models/text-embedding-004",
            "api_key": os.environ["GEMINI_API_KEY"]
        }
    },
    external_memory=ExternalMemory(
        embedder_config={
            "provider": "mem0",
            "config": {
                "user_id": "MadMax"
            }
        }
    )
)

user_inputs = [
    "Hi, my name is Max Moura!",
    "I'm a fisherman.",
    "I really like soccer.",
    "Hey, what do you know about me?",
]

for user_input in user_inputs:
    result = crew.kickoff(
        inputs={
            "user_question": user_input
        }
    )
    print(f'\n👽 User: {user_input}')
    print(f'🤖 Chatbot: {result.raw}')

```

Hope this example helps you get closer to a solution!
