| ==Other Models== | 20.00% - 40.00% | 20.00% - 50.00% |
Limitations
OpenELM is a powerful language model, but it’s not perfect. Here are some of its limitations:
Biases and Risks
OpenELM models are trained on publicly available datasets, which can contain biases and inaccuracies.
Limited Domain Knowledge
OpenELM is a general-purpose language model, but it may not have in-depth knowledge in specific domains.
Dependence on Training Data
OpenELM is only as good as the data it’s trained on.
Potential for Misuse
OpenELM can be used for malicious purposes.
Usage
OpenELM can be used in a variety of applications, including:
- Text generation: OpenELM can be used to generate text for chatbots, language translation, and content creation.
- Code generation: OpenELM can be used to generate code for programming tasks, such as code completion and bug fixing.
- Conversational AI: OpenELM can be used to build conversational AI models that can engage in conversations with users.
To use OpenELM, you can load the pre-trained models from the Hugging Face Hub and fine-tune them for your specific task using instruction tuning.
Format
OpenELM uses a transformer architecture with a layer-wise scaling strategy to efficiently allocate parameters within each layer. This model accepts input in the form of tokenized text sequences.
Supported Data Formats
- Tokenized text sequences
Special Requirements
- Input text must be tokenized using a specific tokenizer (e.g.
meta-llama/Llama-2-7b-hf) add_bos_tokenmust be set toTruewhen using the LLaMA tokenizer
Handling Inputs and Outputs
To generate output from OpenELM, you can use the following code example:
python generate_openelm.py --model apple/OpenELM-1_1B --hf_access_token [HF_ACCESS_TOKEN] --prompt 'Once upon a time there was' --generate_kwargs repetition_penalty=1.2
This will generate output based on the input prompt. You can also pass additional arguments to the generate_kwargs parameter to customize the generation process.
