Bug: “no implicit conversion of String into Integer” when using Together AI with Fetch Available Models

[xpertizeafrica]

Hi CrewAI team,

I'm encountering a bug when trying to set up a custom openai-compatible connection using Together AI.

Bug Description
When I click the “Fetch Available Models” button after setting the following environment variables:

OPENAI_API_KEY=tgp_v1_...
OPENAI_API_BASE=https://api.together.xyz/v1

…I get the following error:

no implicit conversion of String into Integer

What I’ve Confirmed
The Together AI API is fully working — I tested /v1/chat/completions with the model meta-llama/Llama-3.3-70B-Instruct-Turbo and received a valid completion.

Environment variables are correct.

The bug only occurs when trying to fetch the model list from the CrewAI UI.

Likely Cause
Together AI’s /v1/models endpoint returns a dictionary with string keys, not an array. It looks something like:
json

{
"data": {
"meta-llama/Llama-3.3-70B-Instruct-Turbo": {...},
...
}
}
It seems CrewAI assumes the response is indexable like an array, causing the type error.

Let me know if you’d like logs or a sample API response. Thanks for the great tool — just hoping to help make Together AI integration smoother!

Best,
Naim
