Why can LLMs alternate languages sentence by sentence? Redditor probes DeepSeek's code-switching
StructureNorth1799 · reddit · 2026-09-20
A Reddit user asks how LLMs like DeepSeek can alternate languages every sentence, given training data seemingly lacks such samples. The discussion points to multilingual corpora with naturally mixed-language content and shared semantic representations that let models generalize code-switching rather than memorizing sentence-level pairs.
