How to test different LLM models with your AI

Connect Fireworks AI to your agent to run the same prompt through a wide range of models. You'll see exactly how different architectures respond to your specific instructions.

Short answer

How can I compare model responses?

You can use natural language to tell your agent to pull a list of available models and then send specific prompts to them. This lets you side-by-side evaluate how different models interpret your logic. You'll get a clear view of which model follows your constraints best.

The testing outcomes

Where your results land.

Running these commands gives you three specific ways to evaluate model performance.

MODEL LIST

Available model inventory

The AI pulls a full list of accessible models. You'll know exactly which open-source and proprietary options are ready for testing.

OUTPUT

Direct response comparison

By sending prompts to different models, you get raw text outputs. You can then compare how one model's reasoning differs from another.

LOGIC

Instruction adherence

Test how well models follow complex formatting or persona constraints. This shows you which models are reliable for your specific use case.

HUMAN

Final selection

The AI provides the data, but you decide which model is the winner. You choose which model to move into your production workflow.

The workflow

What your AI does when the command arrives.

Your agent handles the heavy lifting of communicating with the Fireworks AI API.

  1. Inventory check

    Your agent first identifies which models are currently available for you to use. This ensures you aren't requesting a model that isn't online.

    list_models

  2. Prompt delivery

    Once you pick a model, the agent sends your text to that specific engine. It handles the technical handshake so you don't have to.

    chat

  3. Text generation

    The agent can also trigger standard text completion tasks. This is useful for testing how models handle raw text without a chat interface.

  4. Result delivery

    The agent brings the model's response back to your chat window. You see the text exactly as the model generated it.

FAQ

How this task behaves.

  • 01

    Can the AI switch models automatically?

    No. You must tell your agent which model to use for each specific request.

  • 02

    Can I use this to fine-tune a model?

    No. This connector is for testing and running inference, not for training or fine-tuning models.

  • 03

    Does the AI save my prompt history?

    The AI client you are using handles your history. This connector only facilitates the communication with the models.

  • 04

    Can the AI delete models from the list?

    No. The agent can only list and interact with the models provided by the API.

  • 05

    Can I test proprietary models through this?

    Yes, as long as those models are included in the list provided by the API.
