The short answer
A Qwen message costs 1 to 8 credits, and which rows you can send to is decided by your plan: Starter includes no Qwen model at all, Pro reaches two Qwen identifiers, and every other Qwen row in the catalogue requires Powerhouse. All of them sit inside the same subscription as the rest of the 280+ model catalogue.
The Qwen rows Whizi prices in its Cost Index, with what each costs to answer once:
| Model | Context window | Credits per message | Cost per standard answer | Per 1,000 answers |
|---|---|---|---|---|
| Qwen3.7 Flash | 1M | 1 | $0.000095 | $0.095 |
| Qwen3 Coder Next | 262K | 1 | $0.00052 | $0.52 |
| Qwen3.6 Flash | 1M | 1 | $0.00075 | $0.75 |
| Qwen3.7 Plus | 1M | 1 | $0.00096 | $0.96 |
| Qwen3.8 27B | 1M | 3 | $0.00205 | $2.05 |
| Qwen3.7 Max | 1M | 5 | $0.003688 | $3.6875 |
| Qwen3.8 Max | 1M | 6 | $0.005 | $5.00 |
The dollar columns are list rates read from OpenRouter on 20 August 2026, for a standard answer of 1,000 input plus 500 output tokens. Across the Qwen rows they run from $0.095 to $5.00 per thousand answers, while the credit column moves only from 1 to 6. Credits are what Whizi charges you, so the two scales do not track each other.
Qwen identifiers with a credit rung
The Cost Index prices 100 rows across 29 providers for comparison, so it is a price index rather than the catalogue. The credit table is the wider list, and it carries further Qwen identifiers, including these:
| Model identifier | Credits per message |
|---|---|
qwen qwen3.8-2.4t-a95b | 8 |
qwen qwen3.6-max-preview | 6 |
qwen qwen3.8-max | 6 |
qwen qwen3.7-max | 5 |
qwen qwen3-max | 3 |
qwen qwen3-max-thinking | 3 |
qwen qwen3-coder | 3 |
qwen qwen3.7-plus | 1 |
Qwen is the largest family by prefix count in the catalogue. The live picker, served by GET /api/models, is the authoritative list of what is on offer today.
One rule governs any Qwen row not named here: a credit cost is a fixed integer per message, so nothing about message length, conversation length or answer length changes it. No Qwen row can reach you without a price either, because a build test fails if any catalogue model or agent id reaches production without a rung.
Which plan reaches Qwen
Model access is decided on the server by identifier, so a Qwen row your plan does not include cannot be reached by editing a request. What a locked row looks like when you send to it anyway is in why a model shows as unavailable.
| Plan | Price | Qwen access | Credits per month |
|---|---|---|---|
| Free | No charge | Any text model, inside a lifetime allowance of 7 messages | 0 |
| Starter | $15.99/month, or $10.99/mo billed annually at $131.88 | None | 400 |
| Pro | $29.99/month, or $19.99/mo billed annually at $239.88 | qwen qwen3.7-plus and qwen qwen3-235b-a22b-2507 | 2,000 |
| Powerhouse | $49.99/month, or $34.99/mo billed annually at $419.88 | Every other Qwen identifier in the catalogue | 8,000 |
Starter reaches exactly four picker entries: Auto, the house assistant Whizi AI, one OpenAI row and one Google row. That is the whole tier, so no Qwen model is available on it.
Pro is a curated list rather than everything cheap: one or two current flagships per family, each family's fast tier, and the high volume workhorses. Two Qwen identifiers made that list. Everything in the catalogue that is not in the Starter set and not in the Pro set resolves to Powerhouse, and that fallback is what puts the rest of Qwen on the top tier. The frontier reasoning rows and the coder family are held back for Powerhouse deliberately.
What a Qwen message spends
Credits are one allowance, spent per message at the rate of the model that answered. A turn is charged whole: if a 6 credit turn does not fit in the remaining balance it is refused rather than part charged, and the send comes back as HTTP 429 with the code message_limit_reached.
| Allowance | At 1 credit | At 3 credits | At 5 credits | At 6 credits | At 8 credits |
|---|---|---|---|---|---|
| Pro, 2,000 credits | 2,000 messages | 666 messages | 400 messages | 333 messages | 250 messages |
| Powerhouse, 8,000 credits | 8,000 messages | 2,666 messages | 1,600 messages | 1,333 messages | 1,000 messages |
What that means for the two Qwen identifiers Pro actually opens: qwen qwen3.7-plus is a 1 credit row, so a 2,000 credit month spent only on it is 2,000 Qwen messages.
Weekly billing, which is offered on mobile only, carries its own numbers: 500 credits per week on Pro and 2,000 on Powerhouse. Credits do not roll over on either cadence, because the balance sums only the rows carrying the current period key.
One thing does not follow you across a mid-thread switch onto a Qwen row: attachments. Only the most recent user message carrying attachments has them forwarded to the provider, so re-asking a Qwen row about a file further up a long thread may need the file attached again. The step by step version is in switching models mid-conversation.
Credit multipliers are shown and charged per platform. The production allowlist today is the web client, which sends its platform on every call, so the badge in the picker and what the turn costs are decided by the same value. Off the allowlist a client gets no multiplier field at all, draws no credit badges, and is charged one message per turn against the older message allowance. On the 1 credit Qwen rows that is the same charge under either scheme. On the 8 credit identifier it is the difference between one message and eight credits. The full mechanics are in the credits reference.
What the 1M window in the table does not buy you
The window column is the model's own window, not what Whizi sends in a turn. Whizi sends a flat 40,000 input tokens and 20,000 output tokens on every catalogue model, and only a model whose window sits under 93,000 tokens gets a smaller proportional budget instead. Every Qwen row in the table clears 93,000, so the 1M rows and the 262K row alike get 40,000 in and 20,000 out. Choosing between Qwen rows on window size alone changes nothing inside Whizi. What happens when a thread outgrows that budget is in when the context is too long.
Where Qwen does not appear
Auto never routes to Qwen. Auto is a router with no fixed credit cost of its own: a turn costs whatever it picked, and no Qwen row is among the things it can pick. Both rules that decide what it picks instead push away from the cheap end. When your plan cannot open a target, Auto does not fall to the cheapest row it can reach: a reasoning question drops to the code model, which reasons well. And difficulty is sticky inside a thread, so the previous turn's model acts as a floor and a follow-up cannot drop back to the cheapest model either. A 1 credit Qwen row is therefore never somewhere Auto arrives on its own. Qwen is a hand pick, every turn.
No Qwen row is in the Recommended section. The picker opens on Whizi AI, Auto and three other rows, and that section is constrained to models reachable at Pro or below so the top of the picker is never locked. Qwen rows live in the All models section.
Image, video and music generation do not use Qwen. Those three picker sections are hand curated and contain no Qwen row. They are also metered differently from each other: a standalone image generation spends only the image counter, which is 100 per month on Pro and 500 on Powerhouse, while standalone video and music jobs spend one credit each in addition to their own Powerhouse gate.
The agent personas do not run on Qwen. Every persona runs on the same house base model, and what a Pro subscription buys there is the prompt, the token budget and the reasoning depth, not a different provider.
- Qwen rows are priced from 1 to 8 credits per message
- Starter includes no Qwen model at all
- Pro reaches two Qwen identifiers, Powerhouse reaches the rest
- A free account can try any text model inside a lifetime allowance of 7 messages
- A credit cost is fixed per model, and message length never changes it
- Every Qwen row in the table clears the 93,000 token threshold, so all of them get 40,000 input and 20,000 output tokens per turn
- Auto cannot pick a Qwen row, so Qwen is a hand pick on every turn
Frequently asked questions
Does turning on web search change what a Qwen message costs?
Not in credits. The charge is a fixed integer per model identifier, so a Qwen turn with search on draws the same rung as one with search off. What it changes is the token side. Web search is a per-request toggle rather than a per-model capability, and a request with it on first carries a cheap probe tool of about 50 tokens, with only a turn where the model actually calls the tool re-issued with real search. Native provider search injects a fixed preamble of roughly 4,400 input tokens. An ordinary search request is capped at 3 results per search and 3 results in total.
Why is the Qwen model I want greyed out in my picker?
Because the gate is resolved on the server by model identifier, and your plan does not include that one. Starter reaches no Qwen row at all, Pro reaches two Qwen identifiers, and every other Qwen row resolves to Powerhouse. Sending to a locked row anyway returns HTTP 403 with the code tier_upgrade_required. A newly added Qwen identifier is Powerhouse-only until it is explicitly promoted into the Pro list, so a row can be locked even though a similar one next to it is not.
My balance is down to a couple of credits. Can I still send to Qwen?
Yes, if you pick a row whose rung fits what is left. Four of the seven Qwen rows the Cost Index prices sit at 1 credit, so a single remaining credit still buys a Qwen message on the same day a 6 credit row is being turned away. The refusal carries the message "Your monthly message limit has been reached.", and weekly plans say "weekly" instead. Nothing carries forward: credits do not roll over, because the balance sums only the rows in the current period, and the arrival of a new period is itself the reset.
Can I try Qwen on a free account?
Yes, within limits. A free account is deliberately not model gated, so it can try any text model in the catalogue, but it carries a lifetime allowance of 7 messages that never resets and 0 credits. Once it is spent, sending returns HTTP 402 with the message "Your free messages are used up. Start a subscription to keep chatting." New accounts can also start a 7 day trial for $0.99.
