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 |

Account credit / Cash equivalent · $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.
