Frequently asked questions

How much does the Hy4 API cost, and how much does it save versus the official API?

Wokey lists input at $0.2919 per 1M tokens and output at $0.87535 per 1M tokens; the official references are $0.834 and $2.501. That is 65% lower for input and 65% lower for output. Request-time pricing controls settlement, and the vendor pricing source is linked on this page.

What is the Hy4 API model ID?

The model ID for Hy4 on Wokey is hy4. Use it exactly as written in the request body's model field or in your client's model setting (for example ANTHROPIC_MODEL in Claude Code, or model in the Codex CLI config.toml); GET https://api.wokey.ai/v1/models also lists it.

Which API forms does Hy4 support, and how do I call it through Wokey?

Hy4 supports /v1/chat/completions (Chat Completions requests). Set the API base URL to https://api.wokey.ai, authenticate with a Wokey API key, and use the canonical model ID hy4; you can start with /v1/chat/completions. The Send a request section includes a curl example for every supported API form.

How do I use Hy4 in opencode, Hermes Agent, and similar clients?

These clients call Hy4 over OpenAI Chat Completions: point the API address at https://api.wokey.ai (clients that expect an OpenAI SDK-style address take https://api.wokey.ai/v1), add your Wokey API key, and use the model ID hy4. Each client's guide shows its config format.

What are the context window and maximum output for Hy4?

The catalog context window is 1,048,576 tokens and the maximum output is 64,000 tokens. These are separate limits, and a request must also satisfy the upstream constraints in effect when it is processed.

How are cache reads and cache writes priced for Hy4?

Cache read: Wokey lists $0.0147 per 1M tokens and the official reference is $0.042 per 1M tokens. Cache write: the vendor does not publish a separate meter, so Wokey also shows — as the public price.

How does calling Hy4 through Wokey differ from OpenRouter?

Wokey lists Hy4 at $0.2919 input / $0.87535 output per 1M tokens, against an official reference of $0.834 / $2.501. OpenRouter states it adds no markup on inference and charges its fee when you buy credits (5.5% by card). Wokey carries a curated set of models and has no per-provider routing parameters, so OpenRouter fits better if you need a wider catalog. The OpenRouter alternative page has the full comparison.

Does Hy4 support streaming, tool calling, and image input?

Streaming is supported; tool calling is supported; image input is supported. These values come directly from the current runtime model catalog and are not inferred from the model name.
