Are AI coding assistants getting worse?

Updated October 2026 · How we answer

Short answerSome developers feel that AI coding assistants get worse after updates, but results vary by tool, model, and task. Changes in models, context limits, and default settings can all affect quality.

Why results can change

AI tools update their models and settings often, and a change that helps one task can hurt another. Context limits matter too, since a large project may be trimmed down to fewer relevant files before the model sees it.

Your own prompts and project setup also affect output. A clear, well-scoped request usually beats a vague one, regardless of the tool. A messy project with unclear names can also produce weaker suggestions.

  • Model updates can change behavior
  • Context limits affect large projects
  • Vague prompts give vague results
  • Messy project structure hurts suggestions

What to do when quality drops

Try a smaller task with a clear example. Compare the same prompt in a second tool to see whether the problem is general or specific to one product. A quick comparison often tells you more than a long debate.

Keep notes on prompts that worked, so you can reuse them when quality dips. Good notes turn a bad week into a fast reset. A tool that once felt sharp can feel dull if your own requests have grown more complicated.

  • Retry with a smaller, clearer task
  • Compare the same prompt in another tool
  • Keep notes on prompts that worked
  • Check your project structure

Common mistakes

  • Assuming a tool is broken after one bad answer.
  • Blaming the model without checking your prompt.
  • Ignoring that a large context may reduce accuracy.
