TMax Hasn't Solved Task Authenticity Yet
Shahules786 · x · 2026-07-14
The author argues that TMax has not yet fully solved the issue of "task authenticity."
Key Points
- TMax increases diversity by uniformly sampling across axes like domain, persona, and language
- However, in the real world, these axes are correlated; for instance, frontend tasks are more likely to use JavaScript, and iOS tasks are more likely to use Swift
- Independent uniform sampling leads to illogical combinations like "iOS tasks in JavaScript"
- Such samples make synthetic traces very obvious unless backed by a robust QA system
Therefore, the author concludes that merely pursuing diversity is insufficient; stronger realistic constraints are necessary.
