Analysis Summary

Llama 2 Chat 13B is a mid-size variant of Meta's original Llama 2 Chat family, released in July 2023. Its intelligence index of 3, GPQA of 0.321, and livecodebench score of 0.098 place it at the lower end of the benchmarked model range. The scicode score of 0.118 indicates minimal coding capability. No pricing or context window data is available.

For businesses, this model offers no practical advantage over current alternatives. Llama 3 and later generations at similar or smaller parameter counts deliver substantially better performance across all relevant dimensions. The 13B size does not provide a meaningful efficiency advantage given the capability gap.

This model is included for historical reference. Any active deployment should be migrated to a current generation open-weight model to access improved reasoning, instruction following, and coding capability.
