In a recent TV interview, the author analyzed why Kimi-K3 chose to open-source its weights despite achieving SOTA-level performance.
- Shifting Moats: The competitive barrier has shifted from static code and weights to continuous evolution and high-quality data flywheels. Without premium post-training data and capabilities, personal fine-tuning often degrades the model.
- Benefits of Open Source: Releasing weights garners massive exposure and community influence. It also attracts engineer feedback to improve the training toolchain, driving ecosystem progress.
