Alleged Doubao V4-Pro Leak Shows Performance Regression, Unconfirmed
teortaxesTex · x · 2026-08-13
The thread discusses strange dynamics surrounding the upcoming release of a model (inferred to be ByteDance's Doubao V4-Pro-0813). The author withholds judgment until the official rollout and English evals are released. Currently, leaked evaluation data from WeChat shows performance regressions (–2.7% for Flash, –9% for Pro), which directionally contradicts expectations, leading the author to doubt this is the model's best version.
