Frequently Asked Questions about Llama 2 (70B)
How much does the Llama 2 (70B) API cost per 1M tokens?+
Llama 2 (70B) by Meta is priced at $0.4 per 1M input tokens and $0.8 per 1M output tokens. With prompt caching enabled, cached input tokens cost $0.1 per 1M tokens, and asynchronous Batch API requests receive a 50% discount.
Should I use a $20/month subscription or the Llama 2 (70B) pay-as-you-go API?+
A flat $20/month consumer subscription is predictable for daily interactive chat and manual coding. However, if you are building software, running automated workflows, or sending low-to-moderate volume with prompt caching enabled, the pay-as-you-go API is typically far more cost-effective and offers higher rate limits without manual UI caps.
How many words and pages fit in Llama 2 (70B)'s context window?+
Llama 2 (70B) features a 4K tokens context window, which equals approximately 3,072 English words or ~8 standard single-spaced pages in a single prompt. Its maximum output generation per turn is 4,096 tokens.
Can I run Llama 2 (70B) locally on my own GPU (Open Weights)?+
Yes, Llama 2 (70B) (70B (also 7B, 13B)) releases open weights that can be self-hosted locally or on private cloud GPUs using vLLM, Ollama, SGLang, or llama.cpp.
Does Meta train on data sent to the Llama 2 (70B) API, and is commercial use allowed?+
100% Isolated when self-hosted on private GPUs or VPC. License tier: Llama Community License (Commercial Permitted). Full commercial ownership of generated outputs. Supported deployment channels include: Self-Hosted GPU (vLLM / Ollama), Private VPC, or Managed Serverless API.
How does Llama 2 (70B) perform on coding and reasoning benchmarks?+
Llama 2 (70B) achieves a composite Intelligence Index of 31/100, scoring N/A% on SWE-bench Verified, N/A% on GPQA Diamond, 56.8% on MMLU-Pro, and 1105 pts on Chatbot Arena Elo.
What is Llama 2 (70B) best used for?+
Llama 2 (70B) is best suited for: एंटरप्राइज ऑटोमेशन, सॉफ्टवेयर डेवलपमेंट, AI एजेंट्स और Meta आधारित प्रोडक्शन सिस्टम. Assessment: Llama 2 (70B) अपने वर्ग में Meta का एक भरोसेमंद और शक्तिशाली AI मॉडल है जो प्रदर्शन और लागत का बेहतरीन संतुलन देता है।

AI Glossary & Architecture Concepts
View full glossary →Key machine learning concepts and benchmarks relevant to Llama 2 (70B):
The basic unit of text that a language model processes, typically representing about 3 to 4 English characters or roughly 0.75 words. For example, the sentence "Artificial intelligence is fast" breaks down into about 5 tokens.
A standardized evaluation suite used to objectively measure and rank an AI model's capabilities across specific tasks — such as SWE-bench Verified for software engineering, AIME for competitive math, or MMLU for general knowledge.
The maximum number of tokens a model can consider at once — both the input it reads and the output it writes. A 1,000,000-token context window can hold roughly 750,000 English words in a single request.
A cost and latency optimization where inference providers store pre-computed attention states for repeated prompt prefixes. Reusing cached tokens typically slashes API input costs by 50% to 90% and cuts TTFT substantially.
A GPU memory optimization that stores previously calculated Key and Value attention matrices so the model does not recompute attention for existing tokens at each generation step. KV cache is vital for fast streaming generation and prompt caching.
The neural network architecture introduced in 2017 that powers modern LLMs, using self-attention mechanisms to process all tokens in a sequence concurrently rather than sequentially.
Benchmark scores, token prices, and rate limits evolve rapidly as AI labs release model updates. Always verify current specifications and pricing on the official provider documentation.
