The short answer
Inkling Small is a Thinkingmachines model priced at $0.45 per million input tokens and $1.2 per million output tokens, with a 524K token context window. One standard answer, meaning 1,000 tokens in and 500 tokens out, costs $0.0010. Inside Whizi it costs 1 credit per message and needs the Powerhouse plan or above.
That makes it mid-priced within the catalogue: 50 of the 89 priced models cost more per answer, and 38 cost less.

What it costs inside Whizi
Whizi meters messages in credits rather than tokens, and Inkling Small is charged at 1 credit per message. The cost does not change with the length of your message or the length of the answer, so a one line question and a long document analysis cost the same.
| Plan | Price per month | Monthly credits | Messages on this model |
|---|---|---|---|
| Powerhouse | $49.99, or $34.99 billed yearly | 8,000 | 8,000 |
Inkling Small is part of the Powerhouse catalogue. Anything not explicitly listed on the Starter or Pro tiers resolves to Powerhouse, which is the deliberate default for the frontier and specialist models. See plans and limits.

The context window in practice
Inkling Small accepts 524K tokens of context, which is roughly 790 pages of text. That is around the median for the priced catalogue.
Advertised context and usable context are not the same thing. Recall tends to degrade before the stated limit is reached, particularly for material in the middle of a long input, so the practical test is to upload a long document and ask about something buried halfway through rather than trusting the number.
The number matters most when you are working from your own files. If a document is too long for the model you picked, switching to a larger-context model in the same conversation carries the thread across, so you are not starting over. See switching models mid-conversation.

Frequently asked questions
How much does Inkling Small cost?
$0.45 per million input tokens and $1.2 per million output tokens at list rates, which works out to $0.0010 for one standard answer of 1,000 tokens in and 500 out, or $1.05 for a thousand of them. Inside Whizi it is 1 credit per message on a monthly allowance, rather than metered per token.
Which Whizi plan includes Inkling Small?
Powerhouse and above, which is $49.99 per month or $34.99 billed yearly. At 1 credits per message, a Powerhouse allowance of 8,000 credits covers 8,000 messages on this model if you spend the whole allowance here, and most people mix in a 1 credit model for routine work so it goes further.
What is the context window of Inkling Small?
524K tokens, which is roughly 790 pages of text and sits around the median for the priced catalogue. Treat that as the ceiling rather than the working figure: recall usually degrades before the stated limit, especially for content in the middle of a long input.
Is Inkling Small expensive compared to other models?
It ranks 39 of 89 priced models by cost per answer, so 50 cost more and 38 cost less. The spread across the whole catalogue is about 4800 times from cheapest to priciest, which is far wider than most people assume, so "expensive" only means anything relative to the specific alternative you would otherwise use.
