Error rate and GPU

1. Llama 2

  • Error Rate:
    • Higher rate of "false refusals" compared to newer models like Llama 3. It sometimes rejects requests it could technically fulfill.
  • GPU Requirements:
    • Recommended: NVIDIA GPUs with at least 12 GB VRAM (e.g., RTX 3060 or better).
    • Also works with AMD GPUs if compatible libraries like ROCm are used.
    • For smaller models (7B), CPU-based use is possible but significantly slower.

2. Llama 3 (Ollama)

  • Error Rate:
    • Reduces the error rate by more than one-third compared to Llama 2, resulting in more reliable responses.
  • GPU Requirements:
    • Ollama is optimized for both CPU and GPU usage.
    • Recommended: NVIDIA GPUs with at least 12 GB VRAM (RTX 3060 or better).
    • Thanks to quantization (e.g., 4-bit), Llama 3 runs efficiently even on devices with limited memory.

3. GPT-J

  • Error Rate:
    • Moderate, lower than Llama 2, but less capable when handling complex queries.
  • GPU Requirements:
    • Recommended: NVIDIA GPUs with 12 GB VRAM or more.
    • AMD GPUs are supported via ROCm, though with limitations.
    • For lightweight tasks, CPU use is possible, but performance is significantly slower.

4. GPT-NeoX

  • Error Rate:
    • Similar to GPT-J but performs better on complex queries.
  • GPU Requirements:
    • Minimum: NVIDIA GPUs with 20 GB VRAM (e.g., RTX A5000 or higher).
    • For large models (20B), multi-GPU support is required.
    • AMD GPU support is experimental.

5. ChatGPT (GPT-4 API)

  • Error Rate:
    • Very low, offering precise and reliable responses.
  • GPU Requirements:
    • No local GPU required, as all processing is handled in the cloud.
    • Minimal hardware on the client side (any internet-capable device is sufficient).

Solutions for Reducing Error Rate

  1. Fine-tuning:

    • Especially useful for Llama 2 or GPT-J to reduce false refusals.
    • Requires NVIDIA GPUs with at least 12 GB VRAM.
    • Effort: High

  2. Fallback logic in the game:

    • Catch rejections by rephrasing requests or providing default responses.
    • Effort: Medium

  3. Switch to Llama 3 (Ollama):

    • Reduces error rate without additional development effort.
    • Ollama optimizes models for NVIDIA GPUs and offers efficient solutions for low-spec devices.
    • Effort: Low
