text: Alternatively, dedicated models for mathematical problem solving with higher precision for the outcome 
  including proof of theorems have been developed such as*Alpha Tensor*,*Alpha Geometry*and*Alpha*
  *Proof*all from Google DeepMind,[157]*Llemma*from eleuther[158] or*Julius*.[159] 
  
  When natural language is used to describe mathematical problems, converters transform such prompts 
  into a formal language such as Lean to define mathematical tasks. 
  
  Some models have been developed to solve challenging problems and reach good results in benchmark 
  tests, others to serve as educational tools in mathematics.[160]
