Qwen3.8 API：リリース日と料金

Qwen3.8 is the next flagship in Alibaba's Qwen series, announced on July 19, 2026. Alibaba says it carries 2.4 trillion parameters and will ship with open weights — an unusual move at this scale. You don't have to wait to get a feel for it. A hosted Qwen3.8-Max-Preview is already running on Alibaba's Token Plan, Qoder, and QoderWork, with the full open-weight release expected to follow. The day Qwen3.8 goes live, it's callable on OrcaRouter through the same OpenAI-compatible API you already use — at provider cost, no markup. Until then, qwen3.7-max is the closest model you can run today.

from openai import OpenAI

client = OpenAI(base_url="https://api.orcarouter.ai/v1", api_key="$ORCAROUTER_API_KEY")

# Wire the id up today — it 425s until launch, then just starts succeeding.
response = client.chat.completions.create(
    model="qwen/qwen3.8",                # routes automatically at launch
    messages=[{"role": "user", "content": "Hello"}],
)
# Before launch → 425 model_not_yet_available
#   { expected_window, closest_live_alternative }
