How we price
Order
Providers are listed cheapest input rate first, then by output rate, a tie going to the creator's own listing. A provider that lists the model without a published rate sits at the end.
Prices
Base-tier, on-demand rates in USD per 1M tokens, converted at ECB reference rates where a provider publishes in another currency. Cached-input and batch rates show only where a provider publishes them. "Cheapest" marks the one provider with the lowest input and output pair; a tie wears no badge.
Cost
Input rate times the input tokens plus output rate times the output tokens, at the monthly volume set above the table. Cached-input, batch, long-context and reasoning-token billing are not modelled.

Heads up: Base-tier, on-demand rates per 1M tokens; cached, batch and long-context tiers excluded. A provider may serve a shorter context or a quantized build than the creator's release. Verify before provisioning. More on how we price.

Common questions
What is Hy4 good for?
Long-horizon agent work and productivity tasks that span many files, with reasoning effort you can set, and it reads images as well as text.
When is Hy4 not a good fit?
Self-hosting for now: Tencent has promised the weights and a system card but not yet published them. No audio or video input, and no knowledge cutoff is published.
What is the cheapest way to run Hy4?
The cheapest hosted rate is $0.417 / $1.2505 per 1M tokens via Tencent.
How does Hy4 compare with Hy4 Preview?
Tencent says the full Hy4 improves on Hy4 Preview in instruction following, long-context comprehension and long-horizon agent tasks, hallucinates less in its internal tests, and adds visual understanding for the first time. Hy4 lists at 50% less per 1M input tokens and 50% less per 1M output tokens than Hy4 Preview. It came out 3 months later, has a smaller context (1M against 1M tokens), takes image input, which Hy4 Preview does not and keeps its weights closed, where Hy4 Preview publishes them under Apache 2.0.
Can I self-host Hy4?
No. Tencent does not publish the weights; Hy4 is available only through hosted APIs.
