Yes, state-of-the-art open source models like LLaMA 3.1 405B and Mixtral 8x22B match or exceed the performance of leading proprietary models on many benchmarks, particularly for reasoning, coding, and multilingual tasks.
Cost depends on model size and usage volume. Small models (8B parameters) can run on consumer GPUs ($0.50-$2/hour on cloud). Large models (70B+) need more powerful hardware ($5-$15/hour). For high-volume applications, open source is often 10x+ more cost-effective than API-based pricing.
Yes, most major open source models (LLaMA 3.1, Mixtral, Qwen) allow full commercial use. Always check the specific license for each model, but generally you can deploy, fine-tune, and sell applications built on these models.
Requirements vary: Small models (8B): 1x RTX 4090 or A10 GPU. Medium models (70B): 2-4x A100 or H100 GPUs. Large models (405B): 8x H100 GPUs or distributed setup. Cloud providers offer GPU instances starting at $0.50/hour for smaller models.
