Llama 2 Chat 7B
Analysis Summary
Llama 2 Chat 7B is one of Meta's original open-weight chat models, released in July 2023. With an intelligence index of 4.3, GPQA of 0.227, and a livecodebench score of 0.002, it sits at the very bottom of the capability range for models with benchmark data. It has been superseded by Llama 3, Llama 3.1, and subsequent Meta releases that deliver dramatically better performance.
For businesses, there is no practical case for adopting this model in 2026. Even for simple tasks, newer small open-weight models from Meta and others offer far superior reasoning, instruction following, and coding capability at similar or lower cost.
At $0.05/1M input, pricing is not a differentiator given the capability gap. This model is retained for historical reference only; any active deployment should be migrated to a current generation.
