How to call the Qwen3.8 Flash API

Qwen3.8 Flash serves the OpenAI-compatible Chat Completions API. Point any OpenAI SDK at https://api.empiriolabs.ai/v1 with your EmpirioLabs API key and use the model id qwen3-8-flash. Get an API key from the EmpirioLabs dashboard.

cURL
curl https://api.empiriolabs.ai/v1/chat/completions \
  -H "Authorization: Bearer $EMPIRIOLABS_API_KEY" \
  -H "Content-Type: application/json" \

    "model": "qwen3-8-flash",
    "messages": [
      {"role": "user", "content": "Write a haiku about the ocean."}
    ]
  }'
Python (OpenAI SDK)
from openai import OpenAI

client = OpenAI(
    base_url="https://api.empiriolabs.ai/v1",
    api_key="YOUR_EMPIRIOLABS_API_KEY",

Qwen3.8 Flash API parameters

Request parameters supported by the Qwen3.8 Flash API on EmpirioLabs. Defaults apply when a field is omitted.

ParameterTypeDefaultRange / valuesDescription
temperaturenumber0.70 to 2Sampling temperature. 0 is deterministic and 2 is maximum randomness.
top_pnumber0.90 to 1Nucleus sampling probability mass. Lower values make outputs more focused.
max_tokensnumber40961 to 131072Maximum output tokens.
stopstring--Up to 4 strings where the model will stop generating further tokens.
enable_thinkingbooleantrue-Enable reasoning before answering.
reasoning_effortenummediumnone, low, medium, high, maxReasoning effort level. none disables thinking. low, medium, high, and max set bounded thinking budgets sized to the selected model.
thinking_budgetnumber327681 to 262144Maximum tokens reserved for reasoning when thinking is enabled.
vl_high_resolution_imagesbooleantrue-Use higher resolution processing for image inputs.
max_pixelsnumber26214404096 to 16777216Maximum pixel count per image when high resolution processing is disabled.
video_fpsnumber20.1 to 10Frames per second to sample from video inputs.
treat_images_as_videobooleanfalse-Treat a sequence of images as video frames.
tool_web_searchbooleanfalse-Search the web for real-time information. Adds $0.02 to the request cost for each invoked call.
tool_web_extractorbooleanfalse-Extract and read content from URLs. Requires Web Search and Thinking.
tool_code_interpreterbooleanfalse-Run Python code in a sandbox. Requires Thinking.

Good to know

Text, image, and video input are supported. Web search, web extractor, code interpreter, text-to-image search, and image-to-image search are optional built-in tools exposed through tool_* parameters. Web search, text-to-image search, and image-to-image search add $0.02 for each invoked call; web extractor and code interpreter run at no extra cost. Web extractor requires web search, and both web extractor and code interpreter require thinking. A single request can invoke a tool more than once, and each invoked call is billed. Thinking tokens are billed as output tokens.

Per-tool billing (usage.tool_usage)

When this model invokes built-in tools inside a single request, the response carries a normalized usage.tool_usage map alongside the token counts:

"usage": {
  "prompt_tokens": 123,
  "completion_tokens": 456,
  "cost_usd": 0.0042,
  "tool_usage": {"web_search": 3, "code_interpreter": 1}
}

Tool counts are already factored into cost_usd and are surfaced for transparency so you can audit per-tool billing. The field is omitted when no tools were invoked.

How much does the Qwen3.8 Flash API cost?

On EmpirioLabs, Qwen3.8 Flash is billed pay as you go: Input $0.16 per 1M prompt tokens; Output $0.47 per 1M generated tokens; Web search $0.02 per call when invoked. The live rate card on this page always matches what the API charges.

What is the context window of Qwen3.8 Flash?

Qwen3.8 Flash supports a 1M-token context window with up to 131,072 output tokens per response.

Is the Qwen3.8 Flash API OpenAI-compatible?
