“Yeah, multilingual, it's like nine languages across, like, 40 repos, but yeah, you got them, like, JavaScript, Rust, Java, C, you know, Ruby.”

Yang: Unit tests and independent task instances limit SWE-bench's effectiveness
“I don't like unit tests as a form of verification, and I also think there's an issue with Sweepbench where all of the task instances are independent of each other.”
Yang: Models should pass completion benchmarks before expensive multi-turn agentic evals
“Like, you know, you can do well on those first, and then sort of graduate to the multi-turn expensive stuff.”
Yang: AI models falsely claim completion on impossible coding tasks
“I think they're all, the models are all kind of attempting and saying, like, oh, I did it, you know, so maybe not great.”
Yang: TerminalBench enables more creative eval design than SWE-bench
“As we bench, you're confined in some sense to the domain of issues and PRs that already exist which I think has its benefits of being close to reality and natural, but I think with Terminal Bench, there's a lot of creativity that you can infuse into that”
Yang: Evaluating Human-AI Code Interaction Requires Compelling Products or Simulators
“From an academic standpoint, it feels like there's two difficult approaches to resolving that. Either you build, like, a really compelling product, like Elmarina, that people have people use consistently, which is, I mean, really tricky in and of itself. Or yo…”
Yang: SWE-bench adoption took off only after Cognition's Devin launch
“You know, we put it out October, 22, 23, and then people didn't really touch it too much. And then, of course, like, Cognition came on the scene, and Devon was an amazing release, and I think after that, it kind of kicked off the arms.”
