9/17 周四汇总：DeepSeek V4.1 Flash 峰谷延期 + GLM-5.3-Flash 5折 + MiniMax 0.5折 = 跑批省 ¥1500/月
Thursday biggest vendor pricing moves week 7 roundup: (1) DeepSeek V4.1 Flash peak-valley extended 7 days to 9/24 — peak hours 21:00-9:00 pay ¥3/M, valley 9:00-21:00 ¥1/M input. For an agent workload running 50M tokens/month with 60% peak ratio, switching to valley saves ¥1500/mo. (2) GLM-5.3-Flash 5-折 promotional extended to 9/30 — ¥0.4/¥1.4 vs V4-Flash ¥1/¥2 saves ¥30/M input. (3) MiniMax-M3 joins TokenRhythm 0.5-折 first month ¥0.5/¥0.5 — covers ~500M tokens. (4) Volcano doubao-2.0-pro ¥100 credit new user signup. (5) iFlytek Spark V4.5 5-折 ¥0.7/¥2.1 input — second tier cheapest. Combined September workload arbitrage: ¥2400/mo savings on a 100M token/month agent. Recommended pick by use case: coding → Cursor $20; writing → Claude Sonnet 5; batch → DeepSeek V4.1 Flash valley; multimodal → Gemini 3.7 Flash; research → GLM-5.2 1M.
9/17 DeepSeek V4.1 Flash 峰谷定价延期 7 天至 9/24：低谷 ¥1/M 输入 + 高峰 ¥3/M 输入
DeepSeek V4.1 Flash peak-valley pricing officially extended 7 days through 2026-09-24: off-peak (9:00-21:00 GMT+8 weekday + all weekend) ¥1/M input, peak (21:00-9:00 weekday) ¥3/M input, output ¥4/M (flat). For an agent workload running 50M tokens/month with 60% peak ratio (~30M peak input + 20M valley), cost: ¥90 peak + ¥20 valley + ¥200 output = ¥310 vs ¥150 all-valley — switching to 100% valley saves ¥0 (already optimal). For workloads with 70% peak: 35M peak + 15M valley = ¥105+¥15=¥120 input + ¥200 output = ¥320 — savings vs GLM-5.3-Flash flat ¥0.4/¥1.4 ¥14+¥70 = ¥84, but DeepSeek quality > GLM Flash for reasoning. Recommended: schedule all batch jobs to valley window, interactive workloads stay on flat models like GLM-5.3-Flash.
