Llama 3.3 70B Instruct
By Meta · United States
Overview
Meta's Llama 3.3 70B — same quality tier as Llama 3.1 405B at one-sixth the size, thanks to improved post-training. Weights are gated on Hugging Face.
When to pick this model
- Self-hosted alternatives to GPT-4 and Claude APIs
- Long-context reasoning and code on multi-GPU servers
- Production workloads where 405B is too expensive to run
- Domain fine-tuning on a high-quality 70B base
- Enterprise deployments cleared under the Llama Community license
VRAM requirements by quantization
| Quantization | VRAM required |
|---|---|
| Q4_K_M (recommended) | 40 GB |
| Q5_K_M | 48 GB |
| Q8_0 | 75 GB |
| FP16 (no quantization) | 140 GB |
VRAM figures include model weights plus a typical 8k KV cache and ~600 MB runtime overhead (Ollama / llama.cpp baseline). Add headroom for higher context lengths.
