Meta's 70B parameter open chat model

Llama-2 70B Chat is a large language model developed and released by Meta as part of the Llama 2 family. It contains 70 billion parameters and is specifically fine-tuned for dialogue and conversational use cases using reinforcement learning from human feedback (RLHF). The model is served through DeepInfra on MindStudio and supports a context window of 4,096 tokens with a maximum response size of 2,500 tokens.

The 70B variant is the largest model in the Llama 2 Chat series, making it suited for tasks that require deeper language comprehension, multi-turn conversation handling, and complex content generation. Meta released Llama 2 under a community license that permits research and commercial use, which contributed to its broad adoption. Note that this model is currently marked as deprecated on MindStudio, so users building new applications may want to consider a more recent alternative.
