GPT-5 Performance Improvements

We’ve rolled out improvements to GPT-5 that make responses noticeably faster and more reliable, especially in multi-step agentic workflows.

What’s changed
  • Reduced latency on GPT-5 responses
  • Better continuity across tool calls
  • Slight quality improvements in complex reasoning tasks

Why it matters

If you use GPT-5 with agents, you’ll notice:

  • Faster execution of multi-tool workflows
  • Responses that feel more intelligent and less fragmented
  • A smoother overall experience in long-running sessions

Available in VS Code v0.545.1+ and JetBrains v0.283.0+
