AtCoder World Tour Finals 2025 (AWTF 2025) is the annual, invitation‑only world championship of the Japanese programming platform AtCoder.
It has two tracks: Heuristic (10 h, 16 Jul) and Algorithm (5 h, 17 Jul), each with 12 onsite finalists selected from a year‑long GP30 ranking system.
In the Heuristic final just finished, an internal OpenAI system competing under the handle “OpenAIAHC” took second place, narrowly losing to top human “Psyho”.
OpenAI is an official sponsor this year, and AtCoder ran the contest as a public “Humans vs AI” exhibition.
The model is not publicly released; the only confirmed facts are the handle, its raw performance, and that it ran within AtCoder’s standard sandbox.
