This list is based on a combination of factors including general popularity, instruction-following capabilities, context window size, and community interest relevant to chatbot and Retrieval-Augmented Generation (RAG) applications.
1. mistralai/Mixtral-8x7B-Instruct-v0.1
Use Cases: Excellent for instruction following, complex reasoning in chatbots, and can handle long contexts for RAG.
View on Hugging Face2. meta-llama/Llama-3-8B-Instruct
Use Cases: Strong general-purpose model, suitable for chatbots with good conversational abilities and RAG applications.
View on Hugging Face3. meta-llama/Llama-3-70B-Instruct
Use Cases: More powerful version of Llama 3, ideal for complex chatbots requiring deep understanding and RAG with extensive knowledge retrieval.
View on Hugging Face4. google/gemma-7b-it
Use Cases: Instruction-tuned model from Google, good for building chatbots and can be used effectively in RAG pipelines.
View on Hugging Face5. microsoft/phi-3-mini-4k-instruct
Use Cases: Smaller and more efficient model, surprisingly capable for chatbots and RAG where resource constraints are important.
View on Hugging Face6. HuggingFaceH4/zephyr-7b-beta
Use Cases: Fine-tuned for instruction following, performs well in conversational settings and RAG tasks.
View on Hugging Face7. TheBloke/Mistral-7B-Instruct-v0.2-AWQ
Use Cases: Quantized version of Mistral 7B, offering a good balance of performance and efficiency for local chatbot and RAG deployments.
View on Hugging Face8. OpenAssistant/oasst-sft-4-pythia-12b
Use Cases: Openly developed assistant model, suitable for conversational AI and RAG experiments.
View on Hugging Face9. databricks/dolly-v2-12b
Use Cases: Instruction-tuned model focused on accessibility, can be used for building chatbots and RAG applications.
View on Hugging Face10. facebook/bart-large-cnn
Use Cases: While primarily for summarization, BART’s encoder-decoder architecture can be adapted for chatbot tasks and RAG by conditioning on retrieved documents.
