Qwen API Pricing 2026: The Complete Alibaba Cloud Model Studio Cost Guide

📅 Data note (Sep 1, 2026): All rates below are synced from the official Model Studio model inference pricing page (last updated Aug 31, 2026) and the Chinese 百炼模型价格页. Standard list prices are shown; limited-time promotions (such as the Qwen3.7-Max 50% discount) are flagged. Always confirm final numbers in the console before production budgeting.

1. How Model Studio Billing Works

Alibaba Cloud Model Studio (the international name for Bailian / 百炼) is Alibaba’s one-stop LLM platform: Qwen text models, DeepSeek, Qwen-VL vision models, QwQ reasoning models, embedding, rerank, speech and image generation, all behind an OpenAI-compatible API. Billing is straightforward:

• Pay-as-you-go by tokens. Fee = input tokens × input price + output tokens × output price. Prices are quoted per 1 million tokens.

• Tiered pricing on some models. For models with context tiers, the price is set by the total input tokens of that single request — and all tokens in the request are billed at that tier’s rate. A 100K-input request on a two-tier model (0–32K, 32K–128K) is billed entirely at the 32K–128K rate.

• Batch inference = 50% off. Models supporting batch calls charge half price for both input and output, with results returned asynchronously.

• Context caching = up to ~90% off cached input. Explicit cache creation costs 125% of the input price, but cache-hit input tokens cost about 10%. Repeated system prompts or long reference documents become dramatically cheaper.

• Off-peak / night discounts. Some models carry automatic night discounts (22:00–08:00 Beijing time, UTC+8) with no signup — currently flagged on Qwen3.7 series list prices.

• Free quota. New accounts get 1 million tokens per model (input and output each), valid for 90 days from activation — across dozens of models this totals roughly 70 million free tokens. On the international (Singapore) deployment, the free quota applies to the models listed there; mainland deployment (Beijing) has its own free-quota list.

2. Qwen API Price Table — International Deployment (USD, per 1M tokens)

These are the International scope rates (Singapore region) most overseas developers use. Standard real-time prices; batch halves them where supported.

3. Qwen API Price Table — Mainland China Deployment (CNY, per 1M tokens)

For China-facing products served from Beijing (North China 2). These rates include the models most commonly used by Chinese teams:

4. How to Pick a Model (and What It Costs You)

• High-volume simple work (classification, tagging, extraction, chat triage): Qwen-Flash. At $0.05/$0.40 per million, 10 million input + 2 million output tokens cost roughly $1.30/day — under $40/month for a busy bot.

• Mainstream app workhorse (summarization, drafting, RAG answers, coding assist): Qwen-Plus / Qwen3.7-Plus. 10M in + 2M out on Qwen3.7-Plus works out to about $8.6/month at standard rates — this is why Plus is the default for production.

• Agentic and hard reasoning (multi-step tools, codebase agents, math): Qwen3.8-Max. Flat $2/$6 across the full 1M context means no long-prompt cliff; the same 10M+2M workload is about $32/month.

• Batch/night jobs: batch API halves everything; night discounts on Qwen3.7 can reach 80% off list. Offline pipelines should never run at peak real-time price.

• DeepSeek is available on the same platform — DeepSeek-V4-Flash and V4-Pro are callable through Model Studio too, so you can A/B vendors without changing infrastructure.

5. Worked Examples: Real Monthly Bills

The takeaway: outside of heavy agent workloads, most production apps run on tens of dollars a month — and the free quota covers the first ~70 million tokens of experimentation entirely.

6. Free Tokens: What New Accounts Actually Get

• 1 million tokens per model, both input and output, for each model in the free-quota list.

• Valid 90 days from Model Studio activation (or model release / application approval, whichever is later).

• International deployment: free quota is granted in the Singapore region; other international regions don’t carry it.

• Mainland deployment: free quota in the Beijing (North China 2) region.

• The old unlimited free developer tier ended April 15, 2026 — the current program is this per-model trial pack.

7. Three Ways to Cut the Bill Further

• Prompt caching. If your system prompt + retrieved context repeats across users, explicit cache hits drop input cost to ~10%. RAG apps routinely cut 60–80% of input spend this way.

• Batch calls for non-interactive work. Evals, embeddings-style sweeps, nightly summaries: 50% off with no quality difference.

• Model routing. Use Flash for triage and simple intents, escalate only the hard 5–10% of requests to Plus or Max. Most “Max-only” apps waste 80%+ of their budget.

8. Getting Started in 10 Minutes

• Register an Alibaba Cloud international account and claim the $200 starter credit (new users; approval ~3 business days where required).

• Open the Model Studio console, activate the service — free tokens are granted automatically.

• Create an API key and call the OpenAI-compatible endpoint (https://dashscope-intl.aliyuncs.com/compatible-mode/v1) with your existing OpenAI SDK — just change base URL and key.

• Start on Qwen-Flash or Qwen-Plus, switch to Qwen3.8-Max only where quality demands it, and turn on caching once prompts stabilize.

FAQ

Is Qwen API free?

The hosted API is pay-per-token, but new accounts get ~1 million free tokens per model (roughly 70 million total) for 90 days. Most Qwen models are also open-weight, so you can self-host on GPU servers at zero per-token cost for steady high volume.

How much does Qwen3.8-Max cost?

$2.00 per million input tokens and $6.00 per million output tokens on international deployment, flat across the entire 1M-token context window. Batch calls halve this to $1/$3-ish effective rates.

Qwen vs DeepSeek — which is cheaper?

DeepSeek-V4-Flash undercuts Qwen-Flash on output price; Qwen-Plus is slightly cheaper on input. Both are callable from the same Model Studio account, so run your own A/B — price differences are smaller than quality-fit differences for most workloads.

Do prices change often?

Alibaba cuts prices aggressively as new models ship — Qwen3.7-Max is currently 50% off list and newer Flash tiers keep dropping. Budget against list prices for long-term planning and treat promotions as upside.
