Frequently Asked Questions

  • What is KAT-Coder-Pro V1's SWE-Bench Verified score?

    73.4% resolve rate on SWE-Bench Verified, which tests autonomous resolution of real GitHub issues.

  • What does parallel tool calling mean in practice?

    The model issues multiple tool calls in a single inference step instead of waiting for each response sequentially. That cuts latency when several operations can run at once.

  • What is the context window size?

    KAT-Coder-Pro V1 has a context window of 256K tokens. You can fit large codebases, multi-file diffs, and extended conversation history in a single context.

  • What types of software engineering tasks does it support?

    Eight task types: feature implementation, feature enhancement, bug fixing, refactoring, performance optimization, test case generation, code understanding, and configuration and deployment.
