# Tencent — models, pricing & selection | Y-API

> Tencent’s Hunyuan line on Y-API has two text-only entries: Hy3, a free 295B-parameter MoE with 21B active, and Hy4 preview, which scales to a 770B backbone with 49B active and a million-token window. Both target grounded, tool-driven work.

## About this vendor

Vendor-level selection advice by Y-API. The per-model pages linked below carry the model-specific checks; nothing here is a measured comparison.

### Where this vendor fits

Hunyuan provides one of the catalog’s free text entries, and Hy4 preview is the cheapest million-window entry in its weight class — a combination that makes the family a low-risk pilot ground for grounded extraction work.

### What to watch for

Hy4’s preview designation is a rollout caveat: catalog availability is not a stability promise. Hy3’s direct-answer default may or may not survive the gateway route, so reasoning settings need their own verification.

## Models on Y-API

Prices are account-credit snapshots from the Y-API catalog. Each model links to its own guide with a cost estimator and a request example.

| Model | Context window | Input / 1M tokens | Output / 1M tokens |
| --- | --- | --- | --- |
| [Hy3](https://y-api.bestvirtualgoods.com/models/tencent/hy3) | 262,144 | Free — no credit deducted | Free — no credit deducted |
| [Hy4 preview](https://y-api.bestvirtualgoods.com/models/tencent/hy4-preview) | 1,048,576 | $1.00 | $3.00 |

$1 paid adds $10 of credit; the cash equivalent is credit consumed ÷ 10. These are Y-API prices, not the publisher’s list prices.

## Choosing within the lineup

Start extraction and multi-turn constraint work on free Hy3. Promote to Hy4 preview when tasks outgrow its 262,144-token window — behind a feature switch, keeping the tested Hy3 path until the pilot earns the migration.

## Before you choose

### Can production workloads run on Hy4 preview?

Possibly, but plan for churn: a preview entry can change behavior or availability without the notice a stable tier gets. Keep a fallback ID, a regression set and a way to halt a run, and re-run the comparison after each upstream update.
