Released July 2023context N/A70b params

Llama 2 70B Chat is Meta's open-weight conversational model tuned specifically for dialogue through reinforcement learning from human feedback. It handles multi-turn conversations with reasonable coherence and follows instructions reliably, though it can be overly cautious and verbose compared to later models. As a 70B parameter model, it offers a meaningful capability ceiling for self-hosted deployments but demands substantial GPU memory to run.

Glossary

CoherenceThe quality of maintaining consistent meaning and logical flow across multiple sentences or exchanges in a conversation.Conversational ModelA language model specifically trained and optimized to engage in multi-turn dialogue with users.GPU MemoryThe high-speed memory on a graphics processor used to store and process model weights and computations during inference.Multi-Turn ConversationsThe ability to maintain context and coherence across multiple back-and-forth exchanges with a user in a single conversation.Parameter ModelA neural network described by the number of learnable weights it contains; more parameters generally mean greater capacity to learn complex patterns, but also require more computational resources.Reinforcement LearningA training method where a model learns by receiving rewards or penalties for its outputs, encouraging it to improve its behavior over time.Reinforcement Learning from Human FeedbackA training technique where human evaluators rate model outputs, and the model learns to produce responses that humans prefer.Self-HostedRunning a model on your own hardware and infrastructure instead of relying on a company's servers or API.
