Measured on Wokey
Last 28 days (2026-09-29 to 2026-10-26), updated every Monday · Real requests from 20+ accounts
- Time to first token, short prompts
- Not enough samples (Median · prompts under 8K tokens)
- Time to first token, agent-size prompts
- Not enough samples (Median · prompts of 32K–128K tokens)
- Prompt cache hit rate
- 98% (Share of input tokens read from cache)
How this is measured
Time to first token runs from the Wokey gateway receiving the request to the first streamed content (text, reasoning summary or refusal). It includes queueing, retries on another account and the model's thinking time, so it is longer than the upstream's own first-token latency. Only successful streamed requests count, banded by prompt size (input plus cache reads and writes).
Cache hit rate = cache-read tokens ÷ input tokens over successful requests. It depends on the client and how it is used; the cache hit-rate pages break it down by client.
Enterprise accounts and Wokey's own test accounts are excluded. A model is shown once at least 20 users used it in the last 28 days and no single user sent more than 50% of its requests, counting accounts registered through one referral chain as one user; each first-token figure needs at least 500 requests.

Which API forms does Tencent Hy4 Preview support, and how do I call it through Wokey?
Tencent Hy4 Preview 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-preview; 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 Tencent Hy4 Preview in opencode, Hermes Agent, and similar clients?
These clients call Tencent Hy4 Preview 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-preview. Each client's guide shows its config format.
What are the context window and maximum output for Tencent Hy4 Preview?
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 Tencent Hy4 Preview?
Cache read: Wokey lists $0.021 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 Tencent Hy4 Preview through Wokey differ from OpenRouter?
Wokey lists Tencent Hy4 Preview at $0.417 input / $1.2505 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 Tencent Hy4 Preview support streaming, tool calling, and image input?
Streaming is supported; tool calling is supported; image input is not supported. These values come directly from the current runtime model catalog and are not inferred from the model name.
