qwen3.5-2b

requesty routes this id across every provider serving qwen3.5-2b, picking on price and health and failing over automatically. the id stays valid when a provider changes underneath it

Base url is https://router.requesty.ai/v1 for every id here. One key reaches the whole catalog.

quickstart

openai compatible
main.py
from openai import OpenAI client = OpenAI(    api_key="YOUR_REQUESTY_API_KEY",    base_url="https://router.requesty.ai/v1",) response = client.chat.completions.create(    model="qwen3.5-2b",    messages=[        {"role": "user", "content": "Explain quantum computing in one paragraph."},    ],) print(response.choices[0].message.content)

Change the base url, use your Requesty key, set the model to any id in the call pane. Existing OpenAI SDK code needs no other edit, and the same key reaches every other model in the catalog, so switching later is a one-parameter change. Browse all models

questions 6

Which providers serve qwen3.5-2b?
qwen3.5-2b is available from 1 provider through Requesty: DeepInfra Inc.. All endpoints share one OpenAI-compatible API and one key, and Requesty fails over between them automatically.
How much does qwen3.5-2b cost?
Pricing starts at $0.02 per million input tokens and $0.10 per million output tokens on the cheapest provider. Prices vary by provider and region; the table above shows every endpoint. Requesty charges exactly what the upstream provider charges, with no markup.
Is qwen3.5-2b open weights?
Yes. qwen3.5-2b is an open-weights model from Alibaba (Qwen), which is why multiple inference providers can host it. Provider choice affects price, latency, and data-privacy terms, all compared above.
What is the context window of qwen3.5-2b?
qwen3.5-2b supports up to 262K tokens of context. Some providers expose a smaller window; check the per-endpoint context column above.
How do I use qwen3.5-2b with the OpenAI SDK?
Install the OpenAI SDK, set base_url to "https://router.requesty.ai/v1", set your API key to your Requesty key, and set the model to "qwen3.5-2b" or any endpoint id from the table above. The quickstart section shows Python, JavaScript and cURL snippets.
Should I call qwen3.5-2b by its managed id or a provider id?
Use the managed id, "qwen3.5-2b". Requesty picks which of the 1 provider serves each request based on price and health, and fails over when one degrades, so the id keeps working while the routing changes underneath it. Send a provider id like "deepinfra/Qwen/Qwen3.5-2B" only when you need one specific deployment and want no failover.
