Open weight LongCat 2.0 matched GPT 5.5 on an agentic game development task for $0. atomic[.]chat compared Meituan's LongCat 2.0 against GPT 5.5 using the kilocode CLI agent. Both models were given the same task: build a retro Duck Hunt game in a single HTML file, then improve it over three agent iterations with duck waves, ammo, and realistic physics. LongCat 2.0: 70.3K tokens ($0.00) GPT 5.5: 64.9K tokens ($0.65) The benchmark was run using atomic[.]chat, a desktop app that runs LLMs locally.
