Route notes
Questions before production traffic.
01How much does the Hy4 Preview API cost?+
Through RouterPlex, Hy4 Preview costs $0.83 per 1M input tokens and $2.50 per 1M output tokens — the vendor list price with 0% markup, billed per token from a prepaid balance you top up from $5. Tencent ships Hy4 as a preview release; the published preview API rate is $0.834 input / $2.501 output per 1M tokens. This model spends heavily on reasoning tokens, so allow a generous max_tokens or replies can come back empty.
02What does one Hy4 Preview agent turn cost?+
A 100K-token input with a 10K-token reply costs about $0.11 on Hy4 Preview. That makes it the 26th cheapest of 54 comparable text models on RouterPlex, roughly 10.0× the cost of the cheapest option (DeepSeek V4 Flash).

Doubao Seed 2.0 Pro from ByteDance is the closest cheaper model on RouterPlex — $0.10 per agent turn against $0.11 for Hy4 Preview, at $0.67/1M input and $3.36/1M output. Both run on the same key and the same endpoint, so switching is a one-line model ID change.
