Provider prices per 1M tokens, updated September 30, 2026.moreless
These are the upstream provider rates. Pay as you go adds 5%, or 0% if you bring your own keys, and there is no per-request fee. Prompt caching and routing change what you pay against these rates, not the rates themselves.

qwen3.8-27b questions
How much does qwen3.8-27b cost?
qwen3.8-27b is priced at $0.20 per million input tokens and $2.50 per million output tokens when accessed via Requesty. Prompt caching is supported, which can cut effective input cost by up to 90% on repeated context. Those are the upstream provider rates: pay as you go adds 5% on top, or 0% if you bring your own provider keys.
What is the context window of qwen3.8-27b?
qwen3.8-27b has a context window of 262K tokens, with a maximum output of 131K tokens per response. That's roughly 350 words of input you can fit in a single prompt.
How does qwen3.8-27b perform on benchmarks?
qwen3.8-27b scores 90.5% on GPQA Diamond, 68.1% on Coding Index, 46.6% on SciCode. See the full benchmark chart above for results across MMLU Pro, GPQA Diamond, SWE-Bench Verified, HumanEval, MATH, AIME, MMMU, and LiveBench.
What can qwen3.8-27b do?
qwen3.8-27b supports vision input, tool calling, extended reasoning, prompt caching, structured outputs (JSON schema). You can call it through any OpenAI-compatible client by pointing base_url to Requesty.
How do I use qwen3.8-27b 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 "deepinfra/qwen3.8-27b". The Quickstart above shows Python, JavaScript and cURL snippets.
Can I run qwen3.8-27b through Requesty?
Yes. qwen3.8-27b runs through Requesty's OpenAI-compatible API, served from DeepInfra Inc.. You do not host the model yourself: point base_url at Requesty, set the model to "deepinfra/qwen3.8-27b", and requests are routed to the upstream provider with automatic failover. The same key gives you 600+ other models too.
Call qwen3.8-27b through one endpoint
One key for this endpoint and 600+ other models. No markup on provider prices, automatic failover, caching built in.
