This paper introduces LoopCoder-v2, a family of 7B parameter parallel loop transformers for code generation, and studies the optimal number of loops, finding that two loops yield significant gains while more loops cause degradation.
LoopCoder-v2 proposes Parallel Loop Transformers (PLT) for efficient test-time computation scaling in code generation, showing that two loops yield significant gains while more loops cause diminishing returns and positional mismatch costs.
