Artificial Intelligence & Next-Gen LLMs
Open Source AI for Enterprise: Llama
Meta's Llama family put capable open-weight models within reach of any engineering team. Self-hosting gives you control over data, cost, and customization, but it also makes you responsible for serving, scaling, and securing the stack. The trade is control versus operational burden, and it pays off when privacy or volume demands it.
要点
- Pick the smallest Llama variant that meets your accuracy target.
- Quantize to 4 or 8 bit to cut memory and serving cost.
- Serve with vLLM or TGI for throughput and batching.
- Fine-tune with LoRA on your domain data instead of full fine-tunes.
- Keep sensitive data inside your own network and VPC.
- Budget for GPUs, observability, and on-call ownership.
- Evaluate against your tasks before committing to a model.
- Plan upgrades as new Llama releases land every few months.
常见问题
Is Llama free for commercial use?
Llama is open weight with a license; check the current terms for your scale and use case.
How much GPU memory do I need?
It depends on model size and quantization; a 7B model fits on a single modern GPU.
Can I fine-tune without ML experts?
LoRA tooling has lowered the bar, but you still need data hygiene and evals.
When should I stay on a hosted API?
When volume is low, latency matters most, or you lack ops capacity.
