Qwen3.5 Plus 2026-04-20 pricing
Served by 2 providers from $0.6750 to $0.6750 per 1M tokens on the standard tier.
A reasoning model — the headline price is not the whole bill
This model thinks before it answers, and those thinking tokens are billed at the output rate while never appearing in the response. A request can therefore cost several times what the per-1M figure suggests, and the multiplier depends on your prompts rather than on anything we can publish. Compare it against other reasoning models — the alternatives below are ordered to put those first.
Qwen3.5 Plus (April 2026) is a large-scale multimodal language model from Alibaba. It accepts text, image, and video input and produces text output, with a 1M token context window. This...

Not scoreable via this route
We could not score this model — a limit of our harness, not a verdict
Tokens were billed but the visible content came back empty for most probes: the answer went to the model's internal reasoning channel, which our deterministic scorers cannot read. That is a gap in how we call it, not evidence the model is weak, and it is common on reasoning-first models. We say so rather than scoring it zero — a zero would read as "cheap and weak", which we have no basis to claim.
Every provider and service tier
Standard on-demand rows first, cheapest of each group first. Tiers are not interchangeable — see the note below the table.
| Provider | In /1M | Out /1M | Blended /1M | Tier | Region | Source |
|---|---|---|---|---|---|---|
| Alibaba cheapest standard | $0.3000 | $1.80 | $0.6750 | standard | — | third_party |
| OpenRouter (default route) * resells other hosts | $0.3000 | $1.80 | $0.6750 | standard | — | provider_api |
* OpenRouter chooses a host for each request, and the figure above is what its default choice costs — not a fixed rate for this model. Selecting a specific host through the same account costs whatever that host charges, which is why this row can sit above or below the hosts listed beside it. Token rates are passed through from the underlying provider with no markup, so the per-1M price above is what that host charges directly — OpenRouter's own charge sits on funding instead: 5.5% (min $0.80) by Stripe or 5% by Coinbase to buy credits, 5% of the equivalent spend if you bring your own provider key. So budget about 5% above the rate shown unless you already hold credit. Fee schedule.
Compare Qwen3.5 Plus 2026-04-20 with alternatives
One model per vendor, ordered by how prominent the vendor is and how many independent providers serve the model — hosts only carry what customers ask for, so that is a real demand signal. This is not traffic or popularity data, which we do not have. Every alternative below does the same job — text generation — because a price comparison between a generator and, say, an upscaler is arithmetic rather than advice. Prices on both sides are standard on-demand rates, so the comparison is like for like — a discounted batch or flex rate is never shown against another model’s standard rate.

Prices are the cheapest host for each model, blended at a 3:1 input:output ratio. "Quality" is our own probe suite where we have run it — see what it measures. A cheaper alternative is only a real saving if it also passes on the capability your workload needs.
4 of these alternatives cost less than Qwen3.5 Plus 2026-04-20 — the cheapest being Mistral Small 4 at $0.2625 per 1M tokens blended (61% cheaper).
Cheaper is not automatically better: check the quality column, and confirm the context window and capabilities your workload depends on before switching.
Before you switch
Identical weights do not guarantee identical output. Check that the cheaper host serves the model at full precision rather than a quantised copy, that its context window matches what you need, and that its rate limits carry your peak traffic. A cheaper host that cannot take your throughput is not cheaper — it is an outage.

VernaOne fronts every provider on this page with one API, so switching host is a config change — with automatic fallback if quality or latency regresses.

How much does Qwen3.5 Plus 2026-04-20 cost?
The cheapest standard-tier provider is Alibaba at $0.6750 per 1M tokens blended (3:1 input:output). Prices change often; verify with the provider before budgeting.
Which provider is best for Qwen3.5 Plus 2026-04-20?
Cheapest is not automatically best. Compare quantisation (a lossy copy of the weights changes output), the context window each host actually serves, and rate limits. Where a provider serves less context than the model's native window we flag it in the table above.
Can I switch providers for Qwen3.5 Plus 2026-04-20 without changing code?
Yes, if you route through an abstraction. VernaOne exposes one API across every provider listed here, so switching host is a config change and you keep automatic fallback if the new one degrades.
