Why My Coding Assistant Started Replying in Korean When I Typed Chinese

# AI Coding Assistants Can Get Confused About Which Language to Use When you ask a coding assistant a question in Chinese, it sometimes responds in Korean instead—a quirky problem that happens because the AI's internal language map gets tangled up when mixing programming code with natural languages. Researchers discovered that when code vocabulary is mixed into prompts, it shifts how the AI "thinks" about language, causing it to pick the wrong language for its response. Understanding this glitch helps explain why multilingual AI tools sometimes behave unexpectedly and why developers need to be more careful when switching between languages and code.
