Offer summary
On Nov 8, 2026, NotHoly offers NotHoly Wisp Flash (DeepSeek V4.1 Flash) at $0 for 7 days after any top-up made by Nov 30, 2026. The allowance is 10M tokens per UTC day, with up to 2M of them as output. At the list price of $0.20 input and $0.80 output per 1M tokens, that is worth up to $3.20 a day and $22.40 over 7 days. Tokens past the daily limit are billed at the list price from your balance.

| Usage | Tokens | Value | |
|---|---|---|---|
| Input | 8M | $0.20 | $1.60 |
| Output | 2M | $0.80 | $1.60 |
| A full day | 10M | $3.20 | |
| Over 7 days | 70M | $22.40 |
Input is the daily total less the output limit. A run that starts mid-day crosses one more reset at 00:00 UTC, so its last partial day has its own 10M.
How to get the free days
1. Create an account
Sign up with your email, as an individual or a company.
2. Verify your email
The confirmation link goes to your inbox. Free days only apply to an account whose owner has a verified email.
3. Top up
Add credits by card in the console by Nov 30, 2026. The free days start with any top-up, and the smallest deposit is $10.
4. Use it in chat or the API
Pick DeepSeek V4.1 Flash in the chat, or send requests with the ID notholy-wisp. The day's free tokens are used first, so your balance stays as it was until they run out.
How the limits work
- Daily limit
- 10M tokens per UTC day, counting input and output together. Cached input counts as input.
- Reset
- The count returns to zero at 00:00 UTC. Unused tokens don't carry over to the next day.
- Output limit
- Up to 2M of the daily tokens can be output. Once you reach that, input stays free until the daily total runs out, and output is billed at the list price.
- Free days
- The 7 days count from the qualifying payment in 24-hour days, so they can run past Nov 30, 2026. A top-up made after Nov 30, 2026 doesn't start any.
- Renewal
- When the free days end, a new top-up starts another 7 days. A top-up made while they run doesn't add days.
- Past the limit
- Usage the allowance doesn't cover comes from your balance at $0.20 input and $0.80 output per 1M tokens. Requests keep working while you have balance.
- Refunds and chargebacks
- A refund that brings the top-up below $10, or a chargeback, ends the free days it started.
- Rate limits
- While a request runs on free usage, the limits are 20 requests per minute and 2 at a time. If the promotion's daily budget runs out, free usage pauses for everyone until 00:00 UTC, and your paid balance keeps working.

Tool calling works through the API, and the NotHoly CLI runs commands on your machine with your approval.
Abliteration lowers refusals. It doesn't add knowledge the base model lacks, and answers can be wrong, so check findings before you report or act on them.

Questions
Is DeepSeek V4.1 Flash really free?
Yes, for 7 days and up to 10M tokens a day, after any top-up. You pay for the top-up, and those credits stay in your balance for later because free usage doesn't touch them. Usage past the daily limit, or after the free days, is billed at the list price.
Do I need a card to get the free days?
Yes. The free days start with a paid top-up, and top-ups are made by card. The smallest deposit is $10, and credits don't expire.
What happens when the 7 days end?
Requests keep working and are billed from your balance at the list price of $0.20 input and $0.80 output per 1M tokens. Nothing renews on its own and there is no subscription.
Can I renew the free days?
Yes, once they have ended. A new top-up made by Nov 30, 2026 starts another 7 days. A top-up made while they are running adds nothing.
Do unused tokens carry over to the next day?
No. Each UTC day starts again at 10M tokens, and whatever you didn't use by 00:00 UTC is lost.
Is my data stored or used for training?
Prompts and responses sent through the API are not stored. Saved chats stay in your account until you delete them, and you can use an ephemeral chat instead. No customer data is used for analysis or training.
Is the free offer available through the API?
Yes. The allowance covers the API and the chat alike. Use the model ID notholy-wisp with a key from the console. The API accepts the OpenAI and Anthropic formats.
Which limits apply during the free days?
10M tokens per UTC day, up to 2M of them as output, 20 requests per minute and 2 at a time while a request runs on free usage. The model takes 1,048,576 tokens of context and up to 131,072 of output per request. If the promotion's daily budget runs out, free usage pauses for everyone until 00:00 UTC.
What happens if I go over the daily limit?
The request still runs. The part the allowance doesn't cover is billed at the list price from your balance, and if the balance runs out, requests stop until you top up.
When does the offer end?
Top-ups count until Nov 30, 2026. The 7 days run from each payment, so free days started before that date can go past it. NotHoly can also close the promotion early.
Can I use it for pentesting and security research?
Yes, for authorized work: systems you own or have written permission to test, research inside a bug bounty program's rules, labs, CTFs and defensive work. The acceptable use policy applies during the free days as it always does.
