The short answer
KAT-Coder-Pro V2.5 is a Kwaipilot model priced at $0.74 per million input tokens and $2.96 per million output tokens, with a 256K token context window. One standard answer, meaning 1,000 tokens in and 500 tokens out, costs $0.0022. Inside Whizi it costs 3 credits per message and needs the Powerhouse plan or above.
That makes it mid-priced within the catalogue: 36 of the 89 priced models cost more per answer, and 52 cost less.
What KAT-Coder-Pro V2.5 costs
List rates are what the provider charges per token. The cost of one standard answer is the more useful number, because it prices the same unit of work across every model regardless of how each one is billed.
| Input, per million tokens | $0.74 |
| Output, per million tokens | $2.96 |
| One standard answer | $0.0022 |
| One thousand answers | $2.22 |
| Context window | 256K tokens |
| Credits per message in Whizi | 3 |

What it costs inside Whizi
Whizi meters messages in credits rather than tokens, and KAT-Coder-Pro V2.5 is charged at 3 credits 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 | 2,666 |
KAT-Coder-Pro V2.5 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.
How it compares on price
Against the cheapest model in the index, Ling-2.6-flash at $0.000025 per answer, KAT-Coder-Pro V2.5 costs 89 times more. Against the median, GLM 4.6 at $0.0015, it costs 1.5 times more.
Its nearest neighbours from Kwaipilot:
| Model | One answer | Context | Credits |
|---|---|---|---|
| KAT-Coder-Air V2.5 | $0.0004 | 256K | 1 |
| KAT-Coder-Pro V2.5 (this page) | $0.0022 | 256K | 3 |
If KAT-Coder-Pro V2.5 is more model than a given task needs, KAT-Coder-Air V2.5 is the cheaper Kwaipilot option at $0.0004 per answer and 1 credit per message. Routing routine work down a tier is the single biggest thing you can do to make an allowance last.
The context window in practice
KAT-Coder-Pro V2.5 accepts 256K tokens of context, which is roughly 380 pages of text. That is below 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 KAT-Coder-Pro V2.5 cost?
$0.74 per million input tokens and $2.96 per million output tokens at list rates, which works out to $0.0022 for one standard answer of 1,000 tokens in and 500 out, or $2.22 for a thousand of them. Inside Whizi it is 3 credits per message on a monthly allowance, rather than metered per token.
Which Whizi plan includes KAT-Coder-Pro V2.5?
Powerhouse and above, which is $49.99 per month or $34.99 billed yearly. At 3 credits per message, a Powerhouse allowance of 8,000 credits covers 2,666 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 KAT-Coder-Pro V2.5?
256K tokens, which is roughly 380 pages of text and sits below 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 KAT-Coder-Pro V2.5 expensive compared to other models?
It ranks 53 of 89 priced models by cost per answer, so 36 cost more and 52 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.
