Llama 3.3 70B Performance Metrics (Hax Analysis 2024-07) · columns: Model, Hardware, Throughput (tok/s), Korean Accuracy Score · 출처 Hax hax.moche.ai/en/p/1195?ref=ai_answer

Model | Hardware | Throughput (tok/s) | Korean Accuracy Score
Llama 3.3 70B | 2x A100 80GB | 25 (측정) | 92% (추정)
Llama 3.3 70B | 1x RTX 4090 | 4 (추정) | 85% (추정)
Hax Server Bench | N/A | N/A (측정대기) | N/A (추정)

Note: Hardware throughput varies significantly based on quantization methods (Q4_K_M vs. FP16) and context window size. Korean accuracy scores are estimated based on standardized benchmarks such as KLUE and custom conversational datasets.

System Prerequisites#

To run Llama 3.3 70B locally, you require substantial compute resources. A minimum of 48GB of VRAM is recommended for quantized versions (4-bit), while full precision requires dual high-end GPUs like A100s or H100s. The operating system should be Linux-based for optimal stability, though Windows with WSL2 is viable. Essential software includes Python 3.10+, CUDA toolkit 12.1+, and the llama.cpp or vLLM inference engine. Ensure your server has persistent storage of at least 50GB for the model weights and swap files.

Step-by-Step Deployment#

First, install the inference framework. For beginners, ollama offers the simplest path. Execute curl -fsSL | sh to install the runtime. Once installed, pull the model using ollama run llama3.3:70b. This command downloads the quantized weights automatically. Alternatively, for higher throughput and custom batching, use vLLM. Install via pip install vllm, then launch the server with vllm serve meta-llama/Meta-Llama-3.3-70B-Instruct. Configure the tensor parallel size based on your GPU count to ensure the model fits in memory.

Optimizing Throughput and Batching#

Throughput is critical for responsive local AI. Use continuous batching to handle multiple concurrent requests efficiently. In vLLM, set --max-num-seqs to match your hardware capacity. For Korean text, ensure the tokenizer correctly handles Hangul syllables. Llama 3.3 shows improved tokenization efficiency compared to previous versions, reducing the token count for Korean sentences by approximately 15% (추정). Monitor GPU utilization with nvidia-smi to prevent thermal throttling, which can degrade performance by up to 30% (추정) under sustained load.

Evaluating Korean Understanding#

To assess the model's Korean capabilities, test it with complex syntactic structures and idiomatic expressions. Use prompts that require nuanced reasoning, such as summarizing news articles or translating technical documentation. Compare outputs against human-reviewed text for accuracy. If hallucinations occur, adjust the temperature parameter to 0.7 or lower for more deterministic responses. The model’s ability to maintain context over long documents is superior to earlier iterations, making it suitable for extensive Korean literary or legal text analysis.

Final Recommendations#

For production environments, implement a reverse proxy like Nginx to manage traffic. Regularly update the inference engine to benefit from performance patches. Always backup your model weights and configuration files. By following these steps, you establish a secure, high-performance local AI environment capable of sophisticated Korean language tasks.
