How to Fix Nanonets Custom Model Not Improving After More Samples

People rely on Nanonets for training a custom AI model to extract specific fields, so running into custom model training not improving accuracy after more samples can feel like an unwelcome surprise right in the middle of a project. The good news is that this is a well-known issue with a handful of reliable fixes.

Most people who run into this find that it’s tied to something specific about their account, device, or file rather than a wider outage, which narrows down the troubleshooting captain77 considerably.

Possible Causes

  • High server demand during busy hours can slow down or interrupt processing related to training a custom AI model to extract specific fields.
  • Cached data or cookies stored locally can conflict with how Nanonets loads or processes new requests.
  • Conflicts with browser extensions or other background software can interfere with how Nanonets runs.
  • A temporary outage or maintenance window on Nanonets’s end can affect requests without much warning.
  • Device-level issues, like low storage or limited memory, can prevent smooth processing during training a custom AI model to extract specific fields.

Initial Troubleshooting Steps

  1. Try the same task in Nanonets again with a simpler input to see if complexity is part of the problem.
  2. Confirm your Nanonets account is in good standing and hasn’t hit a usage or credit limit.
  3. Close other open tabs or apps that might be competing for the same resources Nanonets needs.

Advanced Steps

  1. Reinstall Nanonets entirely if the problem persists, since this clears out any corrupted local data.
  2. Update Nanonets to the latest available version through your app store or browser extension page.
  3. Disable browser extensions one at a time to check whether one of them is interfering with Nanonets.
  4. Check Nanonets’s official status page for any reported outages that might explain custom model training not improving accuracy after more samples.
  5. Clear cached data and cookies specifically tied to Nanonets, then log back in with a fresh session.

Security and Data Warning

Never share your Nanonets login credentials with anyone claiming to offer a faster fix, since this is a common tactic used in account takeover scams. Official support will never ask for your password directly.

When to See a Technician

If you’ve ruled out your own setup entirely and you’re still dealing with custom model training not improving accuracy after more samples, Nanonets’s help center or live support chat is the most reliable next step to take.

Conclusion

Most cases of custom model training not improving accuracy after more samples come down to connectivity, cache, or account settings rather than a lasting flaw. A methodical approach clears it up quickly for the vast majority of users, and it rarely requires any technical background to fix.
