Best Qwen AI Prompts for Coding (2026) — Qwen3.7-Max and Qwen3.8-Max-Preview

Qwen3.7-Max at $2.50/$7.50/M scored 80.4% on SWE-bench Verified and was the highest-placed Chinese model on the Artificial Analysis Intelligence Index at launch in May 2026. Qwen3.8-Max-Preview (July 19, 2026) adds multimodal capability and a 2.4T parameter scale, but benchmark results are not yet published — test on your own workload via the Token Plan preview. Qwen models support tool calling, code execution, long-context document analysis, and multi-turn agent sessions. These prompts are optimised for Qwen3.7-Max via the Alibaba Cloud API and Qwen3.8-Max-Preview via the Token Plan.

1
Long-Context Codebase Analysis
Ask specific questions across an entire codebase using Qwen's 1M context window
[QWEN3.7-MAX OR QWEN3.8-MAX — 1M CONTEXT WINDOW]

I am pasting a large codebase below. Read it in full before answering. Do not summarise what you have read — just confirm you have processed it, then answer my questions.

Questions:
1. [QUESTION 1 — e.g. Where is authentication handled and what library does it use?]
2. [QUESTION 2 — e.g. What happens when a database write fails?]
3. [QUESTION 3 — e.g. Which functions lack error handling?]

For each answer: cite the specific file and function. Do not guess — only answer from what you can see in the code.

Codebase: [PASTE ENTIRE CODEBASE — up to 1M tokens]
2
Generate Production-Ready Code From a Spec
Generate complete production code from a plain English spec with no placeholder stubs
Write complete, production-ready code for the following specification. No stubs, no TODOs, no placeholder comments.

Spec: [DESCRIBE WHAT THE CODE SHOULD DO IN PLAIN ENGLISH]
Language / framework: [SPECIFY]
Dependencies already available: [LIST EXISTING LIBRARIES]
Error handling requirement: [DESCRIBE — e.g. log and retry / throw and let caller handle / return null on failure]
Tests required: [YES / NO — if yes, include them in the output]

Write the complete implementation. If you make assumptions about unspecified details, list them at the end.
3
Multi-File Refactor With Document Understanding
Refactor code to match a design document using Qwen's multimodal document understanding
[QWEN3.8-MAX-PREVIEW — multimodal, use for codebases with design docs or diagrams]

I am providing both a design document and the code that implements it. Identify where the implementation diverges from the design, and refactor the code to match.

Design document: [PASTE DOCUMENT OR UPLOAD IMAGE/PDF IF USING MULTIMODAL]
Current implementation: [PASTE CODE]
What must not change: [ANY BEHAVIOUR OR INTERFACE TO PRESERVE]

Output:
1. List of divergences found (design says X, code does Y)
2. The refactored code that matches the design
3. Any design document sections that are ambiguous or contradictory
4
Agentic Debugging Session
Run an autonomous debugging session — diagnose, fix, explain, and add a regression test
Act as a debugging agent. Work through the following bug autonomously. Do not stop to ask for confirmation unless you reach a point where you genuinely need information I have not provided.

Bug report: [DESCRIBE WHAT IS FAILING AND HOW]
Error message: [PASTE FULL ERROR AND STACK TRACE IF AVAILABLE]
Code: [PASTE RELEVANT CODE]
Environment: [LANGUAGE, FRAMEWORK, OS, RELEVANT VERSIONS]
What I have already tried: [LIST WHAT HAS NOT WORKED]

Work through it step by step:
1. Diagnose the root cause
2. Implement the fix
3. Explain why the bug occurred
4. Add a test that would catch this class of bug in future
5
Code Review With Document Context
Review code against its specification using Qwen's multimodal document + code understanding
[QWEN3.8-MAX-PREVIEW — use multimodal input for architecture diagrams or design docs]

Review the following code against its specification and flag anything that does not match, could break, or introduces risk.

Specification / design doc: [PASTE OR UPLOAD]
Code to review: [PASTE CODE]
Focus areas: [E.G. — security / performance / correctness / maintainability — pick 1-2]

For each issue:
- What is wrong
- Why it matters
- The specific fix

Skip style preferences. Only flag things that will break, introduce risk, or contradict the specification.
6
Generate SQL From Plain English
Write any SQL query from a plain English question with performance notes
Write the SQL query to answer the following question about my database. Output only the query and a brief explanation of what each part does.

Database type: [POSTGRESQL / MYSQL / MSSQL / SQLITE]
Schema: [PASTE RELEVANT TABLE DEFINITIONS OR DESCRIBE]
Question: [DESCRIBE WHAT YOU NEED THE QUERY TO RETURN IN PLAIN ENGLISH]
Performance requirement: [FAST RESPONSE ON X ROWS / BATCH OK / REAL-TIME]
Existing indexes: [LIST OR "UNKNOWN"]

After the query: tell me if any index would significantly improve performance and does not currently exist.
