- DeepMind's code-generation system for competitive programming. AlphaCode (2022) reached roughly the median competitor on Codeforces; AlphaCode 2 later improved the pipeline with stronger models and search.

DeepMind's code-generation system for competitive programming. AlphaCode (2022) reached roughly the median competitor on Codeforces; AlphaCode 2 later improved the pipeline with stronger models and search.

Core technique: generate massive candidate pool (millions), then filter and cluster: brute force + selection.

AlphaCodeium (open): flow engineering, iterative test generation, execution, and refinement around a base model.

The lesson: inference-time compute is architectural. Generating, executing, filtering, and selecting candidates can improve a fixed model without changing its weights.
