Questions

Who runs Hy3?

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 Hy3 cost?

$0.14 per 1M input tokens and $0.58 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 Hy3 through TokenSpend?

Chat and streaming, plus tool calling (Chat, Messages) and JSON schema output (Chat, Responses). It does not support image input 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?

262K tokens of context, prompt and reply together.

Does prompt caching make Hy3 cheaper?

Yes, when the provider caches a repeated prompt prefix. Cached input is billed at $0.035 per 1M tokens instead of $0.14.

How current is this pricing?
