Qwen3.7 Flash API: Pricing, 1M Context, Model ID and How to Call It

Short answer

Qwen3.7 Flash (qwen3.7-flash) is the low-cost, fast model in Alibaba's Qwen3.7 family; the current snapshot is qwen3.7-flash-2026-07-15. Alibaba Cloud Model Studio prices it in three tiers by prompt length. On the international (Singapore) site, prompts up to 32K cost $0.030 per million input tokens and $0.130 per million output tokens; on the China (Beijing) site, ¥0.2 and ¥0.8. The context window is 1 million tokens, with up to 64K tokens of output. On TeamoRouter it uses the same model ID, and on the day of writing (October 22, 2026) the price matches Model Studio's Beijing price, with the same three tiers, which is slightly below the international list price. The live price is on the model page.

What Qwen3.7 Flash is for

Flash is the budget tier of each Qwen generation. According to Model Studio's docs, Qwen3.7 Flash reads text, images and video, answers in text, supports both thinking and non-thinking modes, and supports function calling and structured output.

It suits high-volume work where each request is simple: labeling and classifying text, pulling fields out of text, bulk translation and summaries, first drafts of support replies. For hard reasoning and coding, Qwen3.8-Max or Claude are safer choices.

From Alibaba Cloud Model Studio's text generation and vision docs:

Pricing

Model Studio list price (pricing page, per million tokens, same price with or without thinking):

Output covers both reasoning and the answer. Model Studio's batch calls are half price.

TeamoRouter bills per token at the same price as Model Studio's Beijing rate on the day of writing, with the same 32K and 256K tiers and no monthly fee. That works out slightly below the international list price. Prices follow upstream changes; current numbers are on the model page and the pricing page.

A quick example: 10,000 requests with 2,000 input tokens and 500 output tokens each is 20 million input tokens and 5 million output tokens, ¥8 in total at the Beijing list price, which is also what TeamoRouter charges on the day of writing (roughly $1.14). Thinking mode adds a lot more output tokens.

Watch the tiers: past 32K of input the per-token price triples, and past 256K it is six times the base rate. Do the math before sending a whole book in one request.

Call it through TeamoRouter

Use the OpenAI-compatible endpoint; the base URL includes /v1. Create a key in the dashboard:

from openai import OpenAI

client = OpenAI(base_url="https://api.teamorouter.com/v1", api_key="YOUR_TEAMOROUTER_KEY")
resp = client.chat.completions.create(
    model="qwen3.7-flash",
    messages=[{"role": "user", "content": "Classify this review as positive, neutral or negative: ..."}],
)
print(resp.choices[0].message.content)

Or with curl:

curl https://api.teamorouter.com/v1/chat/completions \
  -H "Authorization: Bearer YOUR_TEAMOROUTER_KEY" \
  -H "content-type: application/json" \
  -d '{
    "model": "qwen3.7-flash",
    "messages": [{"role": "user", "content": "Translate into Spanish: the meeting moved to 3 pm."}]
  }'

FAQ

Qwen3.7 Flash or Qwen3.8 Flash? At Model Studio's Beijing prices, 3.7 Flash is cheaper for short prompts up to 32K (¥0.2 in and ¥0.8 out, versus ¥0.8 and ¥2.7 for 3.8 Flash), while 3.8 Flash is cheaper for prompts over 256K because it has one price all the way to 1M. TeamoRouter currently offers 3.7 Flash.

Does thinking mode cost more? The per-token price is the same, but thinking uses more output tokens, so each request costs more in total.

Can I use it in Codex? No. Codex sends requests through the Responses API, and TeamoRouter's /v1/responses supports GPT models only. For a desktop app, use a client that speaks the OpenAI-compatible API, such as Cherry Studio.

Do I need an Alibaba Cloud account? No. One TeamoRouter key covers Qwen, Claude, GPT and Gemini.
