 This model excels in balancing natural language processing and coding capabilities. 
 Despite being trained on a smaller dataset of 1.4 trillion tokens—compared to LLaMA 2's 2 trillion—Crystal surpasses LLaMA 2 in some challenging English and coding tasks. 
 It demonstrates superior performance in benchmarks like MMLU, HumanEval, and MBPP. 
-By comparing Crystal with other similar work, Crystal is quite balance on language and coding tasks.
+By comparing Crystal with other similar work, Crystal is quite balance on language and coding tasks. Crystal is part of LLM360's Pebble model series.
