If you’re stepping into the exciting world of machine learning and natural language processing, the CausalLM 34B βDemo is an impressive model to explore. However, it does come with a few caveats regarding usage, particularly centered around inference frameworks and precision issues. Let’s dive into how to make the most out of it while keeping the bumps to a minimum!
Understanding the CausalLM 34B βDemo
The CausalLM 34B βDemo is a large language model (LLM) that can generate human-like text based on given prompts. This model operates under specific configurations, and navigating its constraints is crucial for optimal performance.
Prompting the Model
To use the model effectively, it is essential to follow the prompt format designed for it, specifically the ChatML format. This allows for structured communication with the model and underpins its performance.
Issues to be Aware Of
- Precision Problems: The current iterations of the model weights exhibit some precision issues. In the next version update, it’s promised that there will be a rollback of some changes followed by retraining. Be patient; the enhancements are coming!
- Inference Frameworks: It’s important to temporarily steer away from accelerated inference frameworks like **VLLM** as they can affect the quality of the outputs significantly. Instead, opt for Transformers for inference.
- Fast Inference Options: If speed is of the essence, consider using q8_0 quantization through llama.cpp, which is faster and better suited than bf16 vllm for this model until the official version is released.
- Calibration Tips: Avoid using wikitext for quantization calibration as it doesn’t match the original dataset’s distribution, which could lead to misleading results.
Evaluating Model Performance
Performance assessments of models can be visualized through metrics like MMLU. Here’s how the CausalLM 34B βDemo stacks up:
| Models | MMLU (ref: llama7b) |
|---|---|
| microsoftOrca-2-7b | 0.77 |
| mistralaiMistral-7B-v0.1 | 0.46 |
| CausalLM34b-beta | 0.38 |
| 01-aiYi-6B-200K | 0.3 |
Troubleshooting Tips
While using the CausalLM 34B βDemo, issues may arise. Here are some troubleshooting suggestions:
- Check your prompt formatting against the required ChatML format to ensure compliance.
- If experiencing degraded output quality, confirm that you are not using VLLM and instead default to Transformers for your inference tasks.
- For experiencing slow processing, consider switching to q8_0 quantization until official updates roll out.
- If contamination is a concern, you can evaluate the contamination levels using the tools available through Hugging Face Spaces.
