A new benchmark, Forge 2.0, developed by Atlassian, has revealed significant variability in the performance of AI coding models. When tested twice independently, even mid-range models showed score discrepancies of up to 0.15, with some models like Gemini 4 Argon exhibiting a wide range from 0.79 to 0.29. The research suggests that this inconsistency is not necessarily due to model architecture but rather the inherent noise in agentic tasks and the scoring penalties, rather than the completeness of the built application. This variability challenges the reliability of standard AI benchmarks that often rely on single runs, potentially leading users to make suboptimal choices for their coding needs. AI
