How to call Qwen3 Coder Plus

Copyfrom openai import OpenAI
client = OpenAI(base_url="https://api.datallmlab.com/v1", api_key="YOUR_DATALLM_LAB_KEY")
resp = client.chat.completions.create(
    model="qwen/qwen3-coder-plus",
    messages=[{"role": "user", "content": "Hello"}],
    # supports tools=[...] and tool_choice
)
print(resp.choices[0].message.content)

  -d '{"model":"qwen/qwen3-coder-plus","messages":[{"role":"user","content":"Hello"}]}'

Copyimport OpenAI from "openai";
const client = new OpenAI({ baseURL: "https://api.datallmlab.com/v1", apiKey: process.env.DATALLM_KEY });
const r = await client.chat.completions.create({

Prompting tips for Qwen3 Coder Plus

• Be explicit and show the shape of the answer. Spell out format, tone and constraints up front, and include one short example of the output you want — Qwen3 Coder Plus follows concrete instructions better than abstract ones.
• Huge 1M context — but anchor the ask. You can paste whole documents or codebases; models attend most to the start and end, so put the key instruction at the top and restate it after long inputs.
• Give it real tools. Pass a tools=[...] schema instead of asking it to "pretend" — let Qwen3 Coder Plus emit tool calls, execute them, and feed results back for the next turn.
• Constrain JSON with a schema. Use response_format / structured outputs rather than "reply in JSON" to get valid, parseable objects every time.

Tips are derived from Qwen3 Coder Plus's actual capabilities — context window, tool & JSON support, modality and price tier — not generic advice.
