Questions

Who runs Hy4?

Novita runs it, at the list price above. A request that fails there fails with an error, because there is no second provider to move to.

What does Hy4 cost?

$0.417 per 1M input tokens and $1.2505 per 1M output tokens. TokenSpend adds no markup and no per-request fee. If you pay with managed credits, buying them carries a 5% fee.

What can I do with Hy4 through TokenSpend?

Chat and streaming, plus image input (Chat, Messages). It does not support tool calling and JSON schema output here. Tool calling and JSON schema are enabled per provider, only after that provider passes our tests, so a provider chosen by hand may lack them.

How long can my prompt be?

1M tokens of context, prompt and reply together.

Does prompt caching make Hy4 cheaper?

Yes, when the provider caches a repeated prompt prefix. Cached input is billed at $0.021 per 1M tokens instead of $0.417.

How current is this pricing?

It follows rate card 2026-11-09.1, effective 9/17/2026. Source: Private rate card.
