# Tencent HY3 Preview pricing on OpenRouter > Tencent HY3 Preview bills $0.063 per million input and $0.21 output on OpenRouter. Pricing a preview model into unit economics carries a specific risk.

It's a preview model, so that rate carries no commitment to stay. Culpa, a local-first LLM cost, margin, and forecast ledger, dates every rate it stores so a preview repricing shows up as a change rather than as noise. ## Why this happens A preview rate is a marketing position as much as a price. It exists to get a model tried, and the vendor keeps the right to move it when the model leaves preview. Building unit economics on one is fine, and forgetting you did isn't. The failure is quiet: your cost per customer was computed against a rate that later changes, the model keeps working, and the margin you quoted to a board goes stale without a single error appearing anywhere. ## What this usually looks like - A cost-per-customer figure rests on a preview or beta rate nobody flagged as temporary. - Nobody knows which models in your stack are on preview pricing today. - A margin number was computed once and has never been re-priced. - Your cheapest model is carrying a large share of traffic on the strength of a preview rate. ## Common mistakes - Treating a preview rate as a settled one. Why it hurts: It's the rate most likely to move, and it usually moves up when the model graduates. Do instead: Tag preview models in your own records and re-price them on a schedule. - Routing high volume to a preview model without a fallback priced. Why it hurts: If the rate moves you have a migration to run under time pressure and no comparison ready. Do instead: Price the runner-up now, so a repricing is a decision rather than a scramble. - Quoting a margin built on a preview rate without saying so. Why it hurts: The number is right today and silently wrong later, which is worse than being wrong now. Do instead: Carry the rate's date and status with the margin figure, the way Culpa carries confidence. ## Self-check - List every model in your stack and mark which are preview, beta or general availability. - Total the monthly spend sitting on preview rates. That figure is your exposure. - Price the same volume against the nearest generally available model. - The gap between the two is what a graduation would cost you. - Re-read the router's API monthly, because a preview rate changes without an announcement you'll see. ## What a preview rate is worth if it graduates (illustrative) 500M input and 100M output tokens a month on Tencent HY3 Preview at its real OpenRouter rate of $0.063 per million input and $0.21 output, effective 2026-07-02, against DeepSeek V4 Flash at $0.14 and $0.28 as the nearest generally available routed alternative. Volumes are modelled. HY3 Preview: (500 x $0.063) + (100 x $0.21) = $31.50 + $21.00 = $52.50 DeepSeek V4 Flash: (500 x $0.14) + (100 x $0.28) = $70.00 + $28.00 = $98.00 Staying on the preview rate saves $45.50 a month at this volume, 46% of what the alternative would cost Cached input at $0.021 against $0.063 is a 3x discount, not the 10x of a frontier model None of it shows in a router invoice, which reports one total Forty-five dollars a month of the bill rests on a rate the vendor never promised to keep. That's a fine bet as long as somebody wrote down that it's a bet. ## Cost figures Every figure carries its confidence and its source. No figure on this site is provider-reported. - $0.063 per million, Tencent HY3 Preview input rate through OpenRouter [calculated] Source: openrouter.ai/api/v1/models reports 0.000000063 per input token, read 2026-08-03. Multiplied to a per-million figure, and unchanged from Culpa's 2026-07-02 book row. - $52.50 to $98.00, modelled monthly cost of one workload on the preview rate and on the nearest alternative [estimated] Source: Both endpoints from the teardown arithmetic at real rates. A range because the token volumes are modelled. ## FAQ Q: How much does Tencent HY3 Preview cost? A: $0.063 per million input tokens and $0.21 output through OpenRouter, with cached input at $0.021. Read from OpenRouter's models API on 2026-08-03 and unchanged from the rate Culpa's book has held since 2026-07-02. Q: What happens to the rate when it leaves preview? A: Nobody outside Tencent knows, and that's the point. A preview rate carries no commitment, so the useful move is to know what share of your spend depends on it and what the nearest alternative would cost. Q: Why is the cached discount smaller than on Claude or GPT? A: Cached input here is $0.021 against $0.063, roughly a third rather than a tenth. The discount is set per model, and the cheap routed models in the book cluster around a third while the frontier models sit at a tenth. ## Sources - OpenRouter models: https://openrouter.ai/models - Anthropic pricing: https://platform.claude.com/docs/en/docs/about-claude/pricing Run the free Cost Leak Scan: https://app.getculpa.com/scan?source=pseo&slug=tencent-hy3-preview-pricing&cluster=model_pricing Machine-readable index of every guide: https://getculpa.com/api/pages Human-readable index of every guide: https://getculpa.com/guides Site overview: https://app.getculpa.com/llms.txt Privacy: Culpa runs on your infrastructure.
