Qwen2.5-Coder is the latest series of Code-Specific Qwen large language models (formerly known as CodeQwen). As of now, Qwen2.5-Coder has covered six mainstream model sizes, 0.5, 1.5, 3, 7, 14, 32 billion parameters, to meet the needs of different developers. Qwen2.5-Coder brings the following improvements upon CodeQwen1.5:
# pip install aigateway-py openai
# aigateway-py: sub-accounts, evals, replays, jobs, webhook verify.
# openai SDK: chat/embeddings/images/audio — drop-in compat per our SDK's own guidance.
from openai import OpenAI
client = OpenAI(
base_url="https://api.aigateway.sh/v1",
api_key="sk-aig-...",
)
# Try Imagen 4
client.chat.completions.create(
model="google/imagen-4",
messages=[{"role":"user","content":"hello"}],
)
# Try Qwen2.5-Coder-32b-Instruct — same client, same key
client.chat.completions.create(
model="qwen/qwen2.5-coder-32b-instruct",
messages=[{"role":"user","content":"hello"}],
)
