State-of-the-Art Long-Horizon Software Engineering (77.9% DeepSWE v1.1)
Gemini 4 Argon sets a new state of the art on DeepSWE v1.1 (77.9%) and Vibe Code Bench (91.9%), outperforming Claude Opus 5.5 (74.2%) and GPT-6 Astra (74.1%). With a 1M token output limit, Argon can untangle multi-million-line legacy codebases, migrate C/C++ libraries to safe Rust (achieving a 2.7x speedup in Google's libgav1 video decoder), and optimize vLLM GPU kernels end-to-end without mid-response truncation.
- 77.9% on DeepSWE v1.1 and 91.9% on Vibe Code Bench
- Up to 1,000,000 unified input and output tokens per trajectory
- Multi-file architecture refactoring and C++ to Rust migrations
