13 个 OpenRouter 端点实测：7 个固定 205 输入 token 的端点 46% 回复自称 Claude
测 13 个 OpenRouter 端点发现：7 个恰好报 205 输入 token 的端点有 46% 回复提到 Claude，另 6 个仅 0.8%；205 与官方开源 chat template 吻合，temperature 0 时提到 Claude 升至 90%，且与 FP4 量化无关，作者怀疑是服务端配置所致。
MiniMax M3.1 Flash has a weird identity crisis. I tested 13 OpenRouter endpoints. 7 reported exactly 205 input tokens and mentioned Claude in 193/420 replies (46%). The other 6? Just 3/360 (0.8%). That 205-token count exactly matches MiniMax's official open-source chat template. At temperature 0, Claude mentions jumped to 90%. The strangest part is that this doesn't seem to be caused by FP4 quantization. Nebius runs FP4 and almost never mentions Claude. Parasail runs FP8 and does so in 48% of responses. The 205-token group also averages 86% on GPQA vs 88% for the other endpoints. My guess is that the serving configuration plays a major role, but the exact cause is still unclear.
