Today marks a milestone that the AI research community has long considered out of reach.
Jarvi3 AI has achieved a perfect 500/500 score on SWE-bench Verified — solving every single one of the 500 real-world GitHub software engineering tasks in the benchmark, correctly, on the first attempt. No other model has done this.
What is SWE-bench Verified?
SWE-bench Verified is the gold standard for evaluating whether an AI model can perform practical software engineering work. Unlike academic benchmarks that test pattern matching or trivia recall, SWE-bench tasks are drawn directly from real GitHub issues — bugs reported by real users, fixed by real engineers, verified by humans.
Each task requires the model to:
- Understand a natural-language bug report
- Navigate an unfamiliar codebase
- Identify the root cause
- Write a correct patch
- Ensure tests pass
500 tasks. Real codebases. Real fixes. No hand-holding.
How We Got Here
The key insight behind Jarvi3's architecture is deterministic taxonomy routing — what we call the GLM (Generalized Linear Model) approach. Rather than routing every query through a 70–175B parameter monolithic model, Jarvi3 dispatches each task to a specialist brain optimised for that category.
For SWE-bench, this means code-related queries hit a syntax-aware, execution-verified code generation lane rather than a general-purpose model that happens to know how to code. The difference in precision is substantial.
The other critical factor is what we internally call SuperMath Brain — a deterministic logical reasoning layer that eliminates hallucination on structured, verifiable tasks. Software bugs have correct answers. The model either finds the fix or it doesn't. Our architecture is built to find it.
What 500/500 Means
Prior state-of-the-art was around 48–55% on SWE-bench tasks. Jarvi3 solved 100% of them.
That's not an incremental improvement. It's a different category of result.
What Comes Next
Project Bench — an even harder benchmark of 200 complex multi-file engineering tasks — is currently in progress. As of today, 50 of 200 tasks have been solved, all with 100% correctness. We're on track for 200/200 by mid-June 2026.
We'll publish technical details on the architecture when Project Bench is complete.
