Requests cost nothing in chat and by API key for as long as they fit the limit. Below: how to get access, how much it gives and at what point a request becomes paid.

Which models are free

How to get access

1. Sign up in the Kumo console and confirm your email with the link from the message.
2. Subscribe to the Kumo news channel on Telegram. The console shows the link on the free models card.
3. In the same place link Telegram to your account: sign in with Telegram, or enter your username and press Start in the bot. Kumo checks the subscription itself.
4. Open the model catalogue, switch on the «Free» filter and pick a model marked Free. Or send a request by API with your ordinary key.

Intro: a one-time bonus to try the models

The daily limit: top-ups and packages

• Top-up. It needs the channel subscription, a balance of $3 or more and a top-up of at least that amount within the last 30 days. The step has four levels: from $3, from $20, from $50 and from $100. The level follows the current balance: as the balance is spent, the level goes down.
• Packages Starter, Pro, Max and Ultra. A package gives a bigger limit than a top-up of the same amount. Without the channel subscription a package gives 80% of its limit.

• The free limit cannot be saved up, transferred or exchanged for money or tokens.
• When a top-up is refunded, the cost of the free requests made on the Top-up step is withheld from the refund.
• The full text is in the free models promotion terms.

FAQ

Do I have to pay to try it?

No. For the Intro step it is enough to subscribe to the Kumo channel on Telegram and confirm your email. No card and no top-up are needed.

Will money be charged when the limit runs out?

Only if the account has some. A request beyond the limit is paid from the package or the balance at the normal price. If the balance is empty, the request does not run and the API answers with error 402.

Can I use Claude Opus 5.5 for free every day?

Yes, on the daily steps. As of 12 November 2026 a top-up from $3 gives about 8 typical requests to Opus 5.5 a day, the Pro package about 31, Ultra about 73. Short requests spend the limit more slowly.

Why does a request to Claude Fable 5.2 not fit the limit?

The most a request can cost is reserved for it; for a typical request to Fable 5.2 that is about $0.3. On the lower top-up levels the daily limit is smaller than that. Fable 5.2 is free on Intro, on packages and on the top-up levels from $50.

Do free models work in Cursor and Claude Code?

Yes, with your ordinary Kumo API key. But agents send large requests, so the limit is spent faster and dear models may not fit it. For agents on the free limit DeepSeek V4.1 Flash and GLM 5.3 Flash suit better.

Can I get Intro a second time?

No. The bonus is given once per Kumo account and once per Telegram account.

When does the limit renew?

The daily limit of the text models renews every day at 00:00 Moscow time. The image counter resets on Monday at 00:00. What is left is not carried over.
