Ling 3.1 Flash

The official Ling platform lists a limited-time 75% discount at ¥0.50 input, ¥1.50 output, and ¥0.10 cache read per million tokens. Original rates are ¥2.00, ¥6.00, and ¥0.40.

No. The official document places its USD prices under Third-Party Platforms, including OpenRouter and ZenMux. Direct-platform prices are in CNY. Check actual provider quotes before purchasing.

The checked pricing page calls it a limited-time promotion and says original prices will gradually resume. It does not give a fixed end date in the checked text.

Ling lists roughly 560B total parameters, 25B active parameters, and up to 1M context capability. The official service currently exposes 256K context; other endpoints can have different limits. Use the official documentation links for weights and license details.

Use the promotional rate for a scenario only when that is the schedule applicable to the account and billing period. Retain an original-rate scenario for longer-term planning because the official page says the promotion is temporary and original prices will gradually resume. The checked text supplies no fixed end date, so do not schedule a fictional expiry in the calculation. For a consistent workload with ten million uncached input tokens and two million output tokens, the official CNY examples are ¥8 at promotional rates and ¥32 at original rates. Those figures exclude unknown account-specific charges and do not predict future usage. Keep the tariff source date with the forecast. If rates change later, produce a new estimate instead of silently rewriting the assumptions behind a historical report.

The pricing document separates the direct official platform, quoted in CNY, from Third-Party Platforms quoted in USD. They are different published schedules, not exchange-rate conversions supplied by this guide. The OpenRouter reference also tells readers to verify actual platform pricing. A comparison therefore needs the serving platform, current provider route, currency, applicable promotion, cache policy, and source date. Converting currencies, if required, needs an additional exchange-rate source and does not make the service conditions identical. Keep the original CNY tariff visible when reporting official direct-platform pricing. Keep the USD offer associated with its third-party platform rather than describing it as a direct Ling price. An API route’s context limit should also be checked separately: the official documentation currently exposes 256K despite the model’s up-to-1M capability.
