Update, 2026-07-31: qwen/qwen3-coder-480b-a35b-instruct is not available through InferAll. It is not in our served catalog, so a call naming it returns a 404. We verify this by calling every advertised model directly rather than trusting a provider's model list, and we remove ids that do not answer.
The closest code-specialised open model we do serve is poolside/laguna-xs-2.1, free at our open-model rate. Every example below uses it and runs as written:
from openai import OpenAI
client = OpenAI(
base_url="https://api.inferall.ai/v1",
api_key="ifu_your_key_here", # get one at inferall.ai/keys
)
response = client.chat.completions.create(
model="poolside/laguna-xs-2.1",
messages=[{
"role": "user",
"content": "Write a Python function that implements binary search and handles edge cases."
}],
max_tokens=1024,
)
print(response.choices[0].message.content)
What is Qwen3 Coder 480B?
Qwen3 Coder 480B is Alibaba's largest instruction-tuned coding model. The 480b-a35b naming describes its Mixture of Experts architecture: 480 billion total parameters across expert networks, with 35 billion activated per token. This gives it strong coding ability — reasoning, generation, debugging, and code review — while keeping inference cost manageable.
At 480B total parameters it is, as of this writing, the largest open-weight coding model available anywhere. It's specifically trained on code-heavy data and outperforms many closed models on coding benchmarks.
TypeScript / Node.js
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://api.inferall.ai/v1",
apiKey: process.env.INFERALL_API_KEY,

const response = await client.chat.completions.create({
model: "poolside/laguna-xs-2.1",
messages: [
{
role: "system",
content: "You are an expert programmer. Return only code, no explanations unless asked."
},
{
role: "user",
content: "Write a TypeScript function to deep-merge two objects recursively."
}
],

console.log(response.choices[0].message.content);
Streaming

Use cases
Code review:
with open("my_module.py") as f:
code = f.read()
response = client.chat.completions.create(
model="poolside/laguna-xs-2.1",
messages=[
{"role": "system", "content": "Review this code for bugs, edge cases, and improvements."},
{"role": "user", "content": code},
],
)
Debugging:
error_context = """
Error: TypeError: 'NoneType' object is not iterable
Stack trace: ...
Code: for item in get_items(): process(item)
"""
response = client.chat.completions.create(
model="poolside/laguna-xs-2.1",
messages=[{"role": "user", "content": f"Debug this:\n{error_context}"}],
