i am using a google gemini-2.5-flash-preview-05-20 and i set the api keys and also selected chatmodel as gemini-2.5-flash-preview-05-20 but still getting an api error and also tried with ollama but still getting same

I spent hours with the same issue last night and gave up after several hours. I got further than you though. There's API keys for gemini or google. make sure you creayte the correct one. Not sure if my region was the issue.

Not only the issue is with gemini the issue is with all llm model and model providers I fed up and tried with ollma also but still same issue

[voxboxer]

models/embedding-001
(For model embedding)

gemini-1.5-flash
gemini-1.5-pro
(either of these for exact model names)

[Qu1ck1eNO1]

had the same issue, tried using openrouters free APIs but never seemed to work. downloaded ollama local models and it worked (not very well lol). you have to have the EXACT name of model (can very from where you get it). i bit the bullet, and put $20 credit on openai and run the gpt-4.1 model and everything is working as it should.

Thank you very much bro this helps me a lot

models/embedding-001 (For model embedding)

gemini-1.5-flash gemini-1.5-pro (either of these for exact model names)

I have a doubt if we are using chat models means why we should use embeding models
If you reply this helps me a lot 🙏

[Mr-Jack-Tung]

I use gemini-2.5-flash-preview-05-20 with limit RPM = 10 is ok !

[Speed7dev]

I use gemini-2.5-flash-preview-05-20 with limit RPM = 10 is ok !

yes i think it depends on your task

is the gemini-2.5-flash-preview-05-20 with agent 0 is correctly working for you

[Manohar-k-Reddy]

Hey everyone,

I was pulling my hair out with this exact problem and finally figured it out, so I wanted to share the solution in case it helps anyone else.

If you've correctly set up your Google Gemini API key but are still getting that frustrating openai.AuthenticationError: Incorrect API key provided: None, you're not alone. Here's what's going on and how to fix it for good.

The "Aha!" Moment: It's Not Just One Model

The tricky part I discovered is that Agent Zero doesn't just use one AI model. It's actually juggling three different ones behind the scenes for different jobs:

1. The Chat Model: The main one that talks to you.
2. The Utility Model: A "thinking" model for background tasks like summarizing things. This is the hidden one that's easy to miss.
3. The Embedding Model: A specialized model for organizing the agent's memory.

The problem is that even if you set your Chat Model to Google, the Utility Model is often still secretly trying to call OpenAI by default, which causes the crash.

---

Step 1: Making Sure Everything is Pointing to Google

First, we need to tell every part of Agent Zero to use Google.

1. Head into the Agent Zero Settings.
2. You need to find all three model sections and switch the provider to "Google":
   • Find Chat Model -> Set provider to Google.
   • Find Utility Model -> Set provider to Google. (This is the important one!)
   • Find Embedding Model -> Set provider to Google.

After you do this and restart, the OpenAI error will be gone! But... you'll probably get a new error. Don't worry, that's a good sign—it means we're now talking to Google!

---

Step 2: Fixing the "Unexpected Model Name" Error

The new error will probably look something like this: InvalidArgument: 400 ... unexpected model name format.

All this means is that we're using the wrong type of Google model for the memory/embedding job. A chat model like gemini-1.5-flash is great for talking, but Google uses a completely different model for embeddings.

Here's the easy fix:

1. Go back into Settings -> Embedding Model.
2. In the "Embedding model name" field, replace whatever is there with this exact name:

   models/embedding-001
   

3. That's it! Just leave your Chat and Utility models set to your favorite Gemini chat model (like gemini-1.5-flash).

---

The Final, Crucial Step: Restart!

Agent Zero won't apply these new settings until you restart it.

• Save your settings in the UI.
• Go to Docker Desktop and hit the Restart button on your agent-zero-run container.

TL;DR - The Cheat Sheet

If you just want the settings that worked for me, here they are:

• API Key: Your Google API Key is set correctly.
• Chat Model: Provider: Google, Name: gemini-1.5-flash
• Utility Model: Provider: Google, Name: gemini-1.5-flash
• Embedding Model: Provider: Google, Name: models/embedding-001

After I did this, everything finally clicked into place. I really hope this saves some of you the headache I went through.
