Using Gemini 4 Hydrogen on a third-party platform: how to choose among Trymodel, Poe, and OpenRouter

For people who already want Gemini 4 Hydrogen, a 2026-11-14 comparison of Trymodel, Poe, and OpenRouter. Poe’s per-bot compute-point price is left blank where it could not be read; this is not a repeat of the broader aggregator comparison.

If you have already decided to use Gemini 4 Hydrogen, and you do not want to stay only in the official Gemini app, three names come up often: Trymodel, Poe, and OpenRouter. On 14 November 2026, all three could point to this model, but one is a hosted multi-model chat membership with a USD list (yuan on the Simplified Chinese site), one is a bot marketplace that runs on compute points, and one is token-billed developer routing.

The site already has a broader comparison: How Trymodel differs from Poe, Monica, ChatHub, and OpenRouter. That article is about product shape, and its prices were taken on 2026-11-11. This article only answers “now that Hydrogen is available, how do you choose among these three entry points.” It does not repeat Monica, ChatHub, or TypingMind, and it does not rank the three overall.

What was on these three sites that day

Trymodel. At 12:19 on 2026-11-14 (Asia/Shanghai), the catalog API already returned Gemini 4 Hydrogen (gemini-4-hydrogen), listed after Carbon and Argon. Access is Pro / admin. Credits are billed at 3× the official API price of $1.50 / $7.50, which is 45,000 / 225,000 credits per 1 million tokens; thinking tokens count as output. The pricing page that day listed, in English and other languages other than Simplified Chinese, a weekly pass at $3.99 / 7 days, a monthly pass at $14.99 / 30 days, and a yearly pass at $99.99 / 365 days. Each pass is a one-time payment that does not renew automatically when it ends; monthly and yearly passes also offer “auto-renewal (cards only).” USD checkout supports cards and Alipay; WeChat Pay is available when you check out in Chinese yuan on the Simplified Chinese site. There are four credit-pack tiers (45,000 / 117,000 / 237,000 / 447,000 credits at $4.99 / $12.49 / $25.99 / $49.49). In the same thread you can switch to Claude, GPT, Grok, and other models. It is not an official Google account. The Simplified Chinese site shows and charges the yuan list instead.

Poe. The Gemini-4-Hydrogen page could be opened that day, with the description “Google's Gemini 4 Hydrogen for fast reasoning, coding, and agentic workflows.” The API page was also present, and Carbon and Argon appeared in related positions. In other words, Poe had already listed the model as a bot you can chat with and can also call through the Poe API.

This check could not stably read from public HTML how many compute points Hydrogen uses on Poe, so no per-point price is filled in, to avoid inventing one. The subscription page that day defaulted to annual billing: 10,000 points/day at $49.99/year (about $4.17/month), 660,000 points/month at $199.99/year ($16.67/month), 1.65 million points/month at $499.99/year ($41.67/month), 3.30 million points/month at $999.99/year ($83.33/month), and 8.25 million points/month at $2,499.99/year ($208.33/month). The page data also included monthly tiers: $4.99, $19.99, $49.99, $99.99, and $249.99. The copy states that Stripe bills automatically (plus applicable tax), and that you can manage or cancel in settings.

OpenRouter. The model pricing page that day was titled API Pricing. The standard price was $1.50 / $7.50 (per 1 million tokens), cache reads were $0.075, context was 1,048,576, and max completion was also 1,048,576. The page said it is provided by Google AI Studio and Google Vertex, and it marked a release date of 2026-11-12. The same page also showed non-global Vertex prices, batch prices, and other figures; this article quotes only the standard price that was read, and does not quote evaluation scores that were not checked line by line. OpenRouter itself is developer routing: you bring your own key and pay by token under the platform’s rules, rather than buying a hosted chat membership.

For comparison, the public pricing list on TryAllAPI that day already included the gemini-4-hydrogen ID (tags: chat, image understanding, tools). That is an API entry point, not the Trymodel chat page itself.

Comparison table (only facts that were read)

Trymodel Poe OpenRouter
What it mainly is A hosted multi-model chat site; switch models in the same thread Many models plus custom bots; usage is allocated in compute points One API that routes requests to multiple providers
Was Hydrogen listed on 2026-11-14? Yes, gemini-4-hydrogen, display name Gemini 4 Hydrogen Yes, the Gemini-4-Hydrogen page could be opened Yes, the model page title and ID were both Gemini 4 Hydrogen / gemini-4-hydrogen
Prices read that day USD plans as above (yuan on the Simplified Chinese site); Hydrogen credits = official price × 3 Subscription point tiers as above; this bot’s points price was not read Standard inference $1.50 / $7.50, matching the official API pricing page
Payment (as the pages stated) Cards and Alipay; one-time, or card-only auto-renewal. WeChat Pay when paying in yuan on the Simplified Chinese site Stripe auto-charges, which you can cancel Developer credits / billed at provider prices (specific payment options follow the OpenRouter checkout page; this article does not copy unchecked terms)
Do you manage an official key yourself? No Not for chat; the Poe API uses a Poe key Yes; this is an API gateway
Who it fits (by product shape) People who want a priced chat plan and to compare this model with other vendors People who accept a points system and also want a large bot catalog People who want to call the model by token from their own app or script

The table does not conclude “who is cheaper down to the cent”: Poe is missing Hydrogen’s points price; OpenRouter is close to the official API price, but you still have to add how you buy credits and whether there is a platform fee (an earlier broader comparison mentioned a platform fee; this article will not carry an old figure over unless it was rechecked on this Hydrogen page that day — use OpenRouter’s main pricing page on the day you check). Trymodel is a plan plus credits, and you should not convert “a fixed amount per message” against $1.50 / $7.50 without doing the arithmetic.

How to choose, and the steps

Choose Trymodel if you also want: a USD list price (yuan on the Simplified Chinese site), cards or Alipay, the ability to compare Hydrogen with Claude / GPT in the same thread, and a willingness to open Pro. Steps: distinguish one-time payment from auto-renewal on the pricing page, then after you have access open the chat link with the model parameter and confirm the name and ID in the picker. If credits run short, buy a credit pack or switch models. Do not expect official free API quota to appear automatically on this site.

Choose Poe if you also want: a multi-bot marketplace settled in points, and you already accept a USD subscription and Stripe auto-renewal. Steps: open the Hydrogen bot page and the subscription page, check the points cost that bot shows that day in your account (this article does not fill in a number it could not read), and then choose a tier. Do not reverse-engineer Poe points from Trymodel credit numbers.

Choose OpenRouter (or a similar official-compatible gateway) if you also want: to call gemini-4-hydrogen from your own code, reconcile by token, and route among providers. Steps: read that day’s unit price and provider notes on the OpenRouter model page, then configure your own key and limits. It is not a substitute for “open a web page, chat, and switch to Claude” hosted membership. If you would rather use an API console, you can also look at TryAllAPI, using that site’s model list on the day you check.

If what you actually want is official storage, Gemini in Gmail, or Antigravity, go back to official plans rather than looking for a substitute among these three third parties; see Using Gemini 4 on Trymodel versus the official Gemini app and AI Studio.

FAQ

Which of the three is “officially authorized” for Hydrogen?

This check can only confirm that the official Google API and docs use the ID gemini-4-hydrogen; that Poe and OpenRouter public pages already list that name; and that Trymodel’s live catalog already lists it. A page existing is not proof of a commercial authorization relationship. Trymodel’s footer also states that mentions of third-party trademarks do not imply affiliation or endorsement.

Why not compare “how much the same prompt costs on all three”?

Because the billing units are different, and Poe’s points price was not read this time. Dividing a monthly plan fee by a guessed message count, or copying an old platform fee into a new article, would be invention. Compare after you look at a real bill or a live unit price in each account.

Can Hydrogen on Trymodel use official xhigh?

Official docs support xhigh. On 2026-11-14, Trymodel still lowered Gemini xhigh to high. Whether Poe or OpenRouter expose that parameter follows their request docs that day. This article did not test it in those two consoles, so it does not claim that “only one of them supports it.”

There is already a comparison with Poe and OpenRouter. Why this article?

The existing broader comparison covers Monica, ChatHub, TypingMind, and plan shapes as of 2026-11-11, but it does not say whether Hydrogen was already listed, and it does not quote OpenRouter’s $1.50 / $7.50 model page that day. This article only adds that product question, and links back to the broader comparison, rather than copying another “aggregator directory.”
