Frequently Asked Questions
Is Devin or Multiple Agents more reliable?
Based on StupidLLM's incident database, Devin has 12 documented failures (avg severity 4.9/10) while Multiple Agents has 5 (avg severity 4.8/10). Multiple Agents shows better reliability based on average severity scores.
What are the main differences between Devin and Multiple Agents failures?
Devin's most common failure mode is scope explosion, while Multiple Agents most commonly fails via other. Devin has 3 critical incidents vs Multiple Agents's 1.
Which has more critical-severity failures?
Devin has more critical failures (3 vs 1), indicating a higher likelihood of severe, production-impacting incidents.
What is the most dangerous failure mode for Devin?
Devin's most frequent failure mode is scope explosion — its worst documented incident (STUPID-2026-0001) was rated 10/10 severity. Understanding these failure patterns helps teams decide whether Devin is safe for their specific use case.
What is the most dangerous failure mode for Multiple Agents?
Multiple Agents's most frequent failure mode is other — its worst documented incident (STUPID-2026-0032) was rated 10/10 severity. Understanding these failure patterns helps teams decide whether Multiple Agents is safe for their specific use case.
Should I use Devin or Multiple Agents for production code?
Based on StupidLLM's reliability data, Multiple Agents has a lower average failure severity (4.8/10 vs 4.9/10), making it the statistically safer choice for production environments. However, both agents have documented critical incidents — no AI coding agent is risk-free.
How many verified incidents does each agent have?
Devin has 12 verified incidents out of 12 total, while Multiple Agents has 5 verified out of 5. Verified incidents are confirmed against source evidence (GitHub PRs, bug reports, news articles), making them the most reliable data points in StupidLLM's database.
