Llama 2 and the Open-Source LLM Revolution — The End of OpenAI's Monopoly?

Meta made a bold move — Llama 2 is an open-source, commercially usable LLM. For enterprise: finally an alternative to vendor lock-in with OpenAI.

Llama 2 — What’s New¶

Three sizes: 7B, 13B, and 70B parameters. Chat versions fine-tuned with RLHF. The license allows commercial use.

Our Benchmarks¶

• Summarization: 85% of GPT-3.5 quality. Usable.
• Code generation: Java/Python solid, niche languages weaker.
• Czech language: Significantly worse than GPT-3.5.
• Reasoning: The 70B version is surprisingly good.

Self-Hosting¶

The 70B model needs ~140GB VRAM. Quantized versions run on consumer hardware — 13B on an RTX 4090. Data never leaves your infrastructure.

Enterprise Strategy¶

Open-source LLMs change the equation. For high-volume use cases, self-hosting can be more economical. Plus: no vendor lock-in, full control, data sovereignty.

Open-Source AI Is a Legitimate Enterprise Choice¶

We recommend a hybrid strategy — GPT-4 for complex reasoning, open-source for high-volume, privacy-sensitive tasks.
