Could you build this?
No Composer 2 is a custom frontier-level code foundation model trained through continued pretraining and large-scale reinforcement learning.
What it would actually take: Creating a competitive coding foundation model requires collecting and filtering petabytes of high-quality source code, running continued pretraining across massive GPU clusters, and designing advanced Reinforcement Learning from Compiler/Execution Feedback (RLCF) pipelines with customized evaluation harnesses.
