Key Features of OpenChat 3.5

  • Efficient Training with C-RLFT: OpenChat 3.5 is trained using Conditioned Reinforcement Learning from Feedback (C-RLFT), a technique inspired by offline reinforcement learning. This approach allows the model to learn effectively from mixed-quality data without explicit preference labels.

  • Exceptional Performance with Fewer Parameters: Despite having only 7 billion parameters, OpenChat 3.5 delivers performance comparable to or better than models with significantly more parameters, such as ChatGPT and Grok.

  • Accessible Deployment: OpenChat 3.5 can be run on consumer-grade GPUs like the RTX 3090, making it more accessible to developers and researchers compared to resource-intensive proprietary models.

  • Versatile Capabilities: OpenChat 3.5 excels as a generalist model, demonstrating strong performance across a wide range of tasks, including coding, question-answering, and language understanding.

Benchmark Results

OpenChat 3.5 has demonstrated impressive results across various benchmarks, solidifying its position as a top-performing open-source language model. Here are some notable benchmark comparisons:

As evident from the table, OpenChat 3.5 outperforms Grok-0 (33B parameters) on all four benchmarks and surpasses Grok-1 (unknown parameters) on average and in 3 out of 4 benchmarks. It also achieves results comparable to or better than ChatGPT (March 2023 version) in key areas like HumanEval and GSM8k, despite having significantly fewer parameters.

Running OpenChat 3.5 Locally with Ollama

One of the key advantages of OpenChat 3.5 is the ability to run it locally using tools like Ollama. Here's a step-by-step guide:

  1. Install Ollama by running the following command:

    curl -fsSL https://ollama.com/install.sh | sh
  2. Download the OpenChat 3.5 model using the Ollama command:

    ollama run openchat
  3. Start the Ollama server:

    ./ollama serve
  4. In a separate shell, run the OpenChat 3.5 model:

    ./ollama run openchat
  5. Interact with the model using the Ollama REST API or one of the compatible user interfaces, such as:

    • LibreChat
    • Bionic GPT
    • Enchanted (macOS native)
    • HTML UI
    • Saddle
    • Chatbot UI

Here's an example of how to generate text using the Ollama REST API:

curl http://localhost:11434/api/generate -d '{
  "model": "openchat",
  "prompt": "Why is the sky blue?"
}'

And here's how to engage in a chat-like interaction:

curl http://localhost:11434/api/chat -d '{
  "model": "openchat",
  "messages": [
    {
      "role": "user",
      "content": "Why is the sky blue?"
    }
  ]
}'

By following these steps, you can easily run OpenChat 3.5 locally and experience its impressive capabilities firsthand.
