# Looking for an Open-Source LLM to Replace Llama 3.3 70B Versatile > Source: > Published: 2026-08-19 06:29:20+00:00 Hi everyone, I was previously using **Llama 3.3 70B Versatile** through Groq for my application, but this model has been shut down by Groq, so I need to replace it with another model. I am currently looking for a **fully open-source/open-weight model available on Hugging Face** that would be suitable for my use case. My application involves: RAG-based workflows Agentic AI workflows Prompt engineering and prompt generation Structured/JSON output Tool/function calling Good instruction following Reasoning capability Multilingual input/output Production use I am particularly interested in models with **smaller parameter sizes** than 70B if they can provide comparable performance. Some models I am currently considering are: Qwen Mistral DeepSeek Gemma GPT-OSS Could you please recommend **2–5 open-source models** that would be good replacements for Llama 3.3 70B for this type of application? It would also be helpful if you could share your experience regarding: Model quality compared with Llama 3.3 70B Reasoning capability Tool/function calling JSON/structured output reliability Context length VRAM/RAM requirements Inference speed Production deployment experience Recommended quantization, if applicable I am planning to test multiple models on the same set of prompts and compare their results before selecting the final model. Thanks in advance for your recommendations!
