Collection to track the LLMs I fine-tuned for code generation • 4 items • Updated • 1
LlaMa 2 Coder 🦙👩💻
LlaMa-2 7b fine-tuned on the CodeAlpaca 20k instructions dataset by using the method QLoRA with PEFT library.
Model description 🧠
Llama 2 is a collection of pretrained and fine-tuned generative text models ranging in scale from 7 billion to 70 billion parameters. Meta developed and publicly released the Llama 2 family of large language models (LLMs), a collection of pretrained and fine-tuned generative text models ranging in scale from 7 billion to 70 billion parameters. Our fine-tuned LLMs, called Llama-2-Chat, are optimized for dialogue use cases. Llama-2-Chat models outperform open-source chat models on most benchmarks we tested, and in our human evaluations for helpfulness and safety, are on par with some popular closed-source models like ChatGPT and PaLM.
