Error Message

Error handling consistency
Error messages that are clear and actionable

Root Cause

Erodes trust: Users encounter broken features that are documented, making the project feel incomplete
Regression burden: Each new feature adds potential for breaking existing functionality
UX friction: Non-working features frustrate users and create support overhead
Maintenance debt: The longer bugs sit, the harder they are to fix (context is lost, root causes become unclear)

Pre-Submission checklist

Please complete all items before asking a LiteLLM maintainer to review your PR

I have Added testing in the tests/test_litellm/ directory, Adding at least 1 test is a hard requirement - see details
My PR passes all unit tests on make test-unit
My PR's scope is as isolated as possible, it only solves 1 specific problem
I have requested a Greptile review by commenting @greptileai and received a Confidence Score of at least 4/5 before requesting a maintainer review

Delays in PR merge?

If you're seeing a delay in your PR being merged, ping the LiteLLM Team on Slack (#pr-review).

CI (LiteLLM team)

CI status guideline:

50-55 passing tests: main is stable with minor issues.

45-49 passing tests: acceptable but needs attention

<= 40 passing tests: unstable; be careful with your merges and assess the risk.

The Ask

Take a step back from new features and focus on making everything already documented work correctly.

The proxy and UI have accumulated numerous bugs and broken/incomplete features over successive releases. Rather than continuing to add new functionality, we should prioritize shipping a solid, reliable baseline where every documented feature actually works as expected.

Why This Matters

Erodes trust: Users encounter broken features that are documented, making the project feel incomplete
Regression burden: Each new feature adds potential for breaking existing functionality
UX friction: Non-working features frustrate users and create support overhead
Maintenance debt: The longer bugs sit, the harder they are to fix (context is lost, root causes become unclear)

Suggested Focus Areas

Proxy

Request routing reliability
Error handling consistency
Health checks and status endpoints
Authentication/authorization edge cases
Timeouts, retries, and fallback behavior

UI / Dashboard

Working log viewing and filtering
Accurate usage metrics and reporting
Navigation and settings that actually persist
Responsive behavior across viewports
Real-time updates (if applicable)

General

All documented API endpoints behaving as specified
Configuration options that actually do what they claim
Error messages that are clear and actionable
Feature flags that correspond to actual behavior

What We're Not Asking For

This is NOT a call to stop development or remove features. It's a request to:

Audit the existing feature set against actual behavior
Fix or document broken/unreliable features
Establish stronger regression testing before releases
Slow down new feature additions until the foundation is solid

How to Help

Confirm which issues you're aware of in the proxy/UI that match this pattern
Link related issues that should be addressed as part of this stabilization effort
Consider pinning this issue while the work is done

We want to love litellm — right now the bones are great but the finish work is needed.

Fix Plan

To address the stabilization effort, we will focus on the following steps:

Proxy Fixes

Implement reliable request routing using a routing table
Enhance error handling with standardized error codes and messages
Develop comprehensive health checks and status endpoints
Improve authentication/authorization with edge case handling
Configure timeouts, retries, and fallback behavior

Example code for reliable request routing:

from flask import Flask, request

app = Flask(__name__)

# Define a routing table
routing_table = {
    '/api/v1/users': 'user_service',
    '/api/v1/products': 'product_service'
}

@app.route('/', defaults={'path': ''})
@app.route('/<path:path>')
def catch_all(path):
    # Route requests based on the routing table
    if path in routing_table:
        return routing_table[path]
    else:
        return '404 Not Found', 404

UI/Dashboard Fixes

Implement working log viewing and filtering using a logging library
Develop accurate usage metrics and reporting with data visualization
Ensure navigation and settings persist across sessions
Improve responsive behavior across viewports
Implement real-time updates using WebSockets or Webhooks

Example code for log viewing and filtering:

// Use a logging library like Log4js
const log4js = require('log4js');

// Configure logging
log4js.configure({
  appenders: { console: { type: 'console' } },
  categories: { default: { appenders: ['console'], level: 'info' } }
});

// Log messages with filtering
const logger = log4js.getLogger();
logger.info('Info message');
logger.warn('Warning message');
logger.error('Error message');

General Fixes

Audit and fix all documented API endpoints
Ensure configuration options work as claimed
Improve error messages for clarity and actionability
Align feature flags with actual behavior

Example code for auditing API endpoints:

import requests

# Define a list of API endpoints to audit
endpoints = [
    '/api/v1/users',
    '/api/v1/products'
]

# Audit each endpoint
for endpoint in endpoints:
    response = requests.get(endpoint)
    if response.status_code != 200:
        print(f'Error: {endpoint} returned {response.status_code}')

Verification

To verify the fixes, we will:

Test each feature and endpoint manually
Run automated regression tests
Monitor user feedback and support requests

Extra Tips

Prioritize fixes based on user impact and frequency of use
Use version control and branching to manage changes
Continuously integrate and deploy changes to production
Monitor and analyze user behavior to identify areas for improvement
