Call qwen3.8-max through RouterPlex's OpenAI-compatible API — vendor list price, 0% markup, billed per token from a prepaid balance. No subscription required.
On cost it sits in the mid-range band of the catalog: the 23rd cheapest of 38 comparable text models, at about $0.26 per 100K-in / 10K-out agent turn — cheaper than 14 others on the same key. Its 1M context window ranks 5th of 38.
Alibaba publishes a discounted cache-read tier for this model. RouterPlex does not pass a separate cache tier through yet, so cached prompt tokens are billed at the standard $2 input rate.
These examples apply the published input and output token rates directly. Actual cost depends on the tokens your client sends and the model returns.
10K input + 1K output tokens
100K input + 10K output tokens
Every model below runs through the same endpoint and the same API key, so moving between them is a one-line model ID change. Costs are for the same 100K-in / 10K-out turn.
Quality is a separate question from price — see Qwen3.8 Max benchmark results before optimising on cost alone. Qwen3.8 Max reads images; for generating them see GPT Image 2 pricing.
