What you need to know about Hy4
Tencent, based in China, put Hy4 online on November 4, 2026. It accepts text and images as input and produces text. Its context window reaches 1,048,576 tokens, larger than 92 % of the models in the registry, and it can write up to 65,536 tokens in one go.
It is a recent model: real-world feedback and independent scores are still scarce.
Hy4 pricing
On OpenRouter, Hy4 costs $0.42 per million input tokens and $1.25 per million output tokens. Counting three tokens read for every token written, its average price is $0.626 per million, more expensive than 44 % of paid models (1.3 times cheaper than the median of $0.8).
A concrete example: a task that sends 2,000 tokens (about 1,500 words) and receives a 500-token answer costs $0.0015. At 1,000 tasks a day, budget $44 a month. The price calculator redoes this with your own volumes.
Tokens already sent and cached are billed at $0.021 per million.
Performance and benchmarks
Epoch AI does not yet publish a capabilities index for Hy4. We therefore show no made-up performance rating: only price, context and features count towards its score.
Features, privacy and local use
- It supports tool calling, so it can drive an AI agent, call APIs or MCP servers.
- It can answer in an enforced JSON format (structured outputs).
- It is a reasoning model: it "thinks" before answering, which helps on hard tasks but uses more output tokens.
Its weights are open and downloadable from Hugging Face: you can run it on your own machines without sending your data to a third party.
