Qwen3 Coder Flash is Alibaba's fast and cost efficient version of their proprietary Qwen3 Coder Plus. It is a powerful coding agent model specializing in autonomous programming via tool calling...

History

Qwen3 Coder Flash became available via the Alibaba API on 2025-09-17.

Training & availability

Training data has a knowledge cutoff of 2025-06-30 — information about events after that date is unlikely to appear in the model's responses. Alibaba has not released the underlying model weights — access is via their hosted API only.

Capabilities

Context window: 1.0M tokens.
Input modalities: text.

Recommended for: long-context, cheap.

Limitations

Text-only — cannot process images, audio, or video inputs.

Pricing

Input: $0.1950 per 1M tokens
Output: $0.9750 per 1M tokens

Quick start

Minimal example using the OpenRouter API. Copy, paste, replace the key.

from openai import OpenAI

client = OpenAI(
    base_url="https://openrouter.ai/api/v1",
    api_key="sk-or-...",
)
resp = client.chat.completions.create(
    model="alibaba/qwen3-coder-flash",
    messages=[{"role": "user", "content": "Explain quantum computing in one sentence."}],
)
print(resp.choices[0].message.content)
