en.Wedoany.com Reported - Anthropic is improving the performance of Claude Code through a project involving approximately 1,000 human software engineers. The project, internally named "Marlin" at the data labeling company Snorkel AI, focuses on fine-tuning Claude Code's responses to better align with developers' real-world working environments.

AI companies like Anthropic typically outsource data work to third-party organizations such as Snorkel, which then hires contractors to teach AI specialized domain knowledge and perform other tasks to improve the model. According to two Snorkel contractors involved in the project, they are paid $280 (approximately 1,902 RMB) per task for writing prompts and reviewing code, with each task taking about an hour. Some submissions require multiple rounds of communication with Snorkel's approval layer.

In the Marlin project, contractors with software engineering backgrounds conduct A/B testing on code generated by two different models. Workers compare the two sets of outputs, select the preferred version, and determine whether the model meets the level of detail required by the prompt. One contractor stated that the project aims to ensure the model fully satisfies the detailed requirements in the prompts, essentially training Claude Code to generate cleaner, more maintainable code.

It is understood that the project is still ongoing, and the contractors are unaware of which version of the model they are evaluating.
