This paper presents a specialization pipeline for post-training language models to achieve gold-medal performance in coding competitions, demonstrating top scores on IOI benchmarks using techniques like supervised fine-tuning and reinforcement learning.

MARS is a multi-agent LLM framework using specialized agents for different algorithmic topics to solve competitive programming problems, achieving a 0.624 pass rate with lower cost and variance than direct prompting.

This paper introduces CurveShift, an analysis method that separates overall ability gains from difficulty-specific improvements in LLM agents. Using METR time-horizon data and LiveCodeBench, it finds that most apparent shifts toward harder tasks are ceiling effects, though a genuine hard-task effect exists for reasoning models in competitive programming.

A new AI model has achieved superhuman performance in competitive programming, marking a significant milestone in AI capabilities.

Scores update from the ongoing AtCoder heuristics finals, which will continue until July 8, 19:00 JST.

Announces the free availability of the 'Competitive Programmer’s Handbook', covering 30 important DSA topics for tech interview preparation.

CP-Agent presents a calibrated risk-controlled approach for feedback-driven competitive programming using large language models, achieving significant improvements on benchmarks without parameter updates.

GrandCode is a multi-agent reinforcement learning system that achieves grandmaster level in competitive programming, consistently beating all human participants in live Codeforces contests using a novel Agentic GRPO method.

Solvita is an agentic evolution framework that enables continuous learning in code generation through reinforcement learning updates to graph-structured knowledge networks, achieving state-of-the-art performance on competitive programming benchmarks.

This profile interviews Cognition AI co-founder Scott Wu, exploring his background as a competitive programming prodigy and the rapid commercial success of his AI coding agent Devin, which has reached a $445 million revenue run rate and a $25 billion valuation.
