Finding the Scaling Laws of Agents. The first and the best multi-agent framework.
🐫 CAMEL is an open-source community dedicated to finding the scaling laws of agents. We believe that studying these agents on a large scale offers valuable insights into their behaviors, capabilities, and potential risks. To facilitate research in this field, we implement and support various types of agents, tasks, prompts, models, and simulated environments.
The framework enables multi-agent systems to continuously evolve by generating data and interacting with environments. This evolution can be driven by reinforcement learning with verifiable rewards or supervised learning.

Canary tokens are a free, quick, painless way to help defenders discover they've been breached (by having attackers announce themselves. How tokens works (in 3 short steps):
- Visit the site and get a free token (which could look like an URL or a hostname, depending on your selection.)
- If an attacker ever uses the token somehow, we will give you an out of band (email or sms) notification that it's been visited.
- As an added bonus, we give you a bunch of hints and tools that increase the likelihood of an attacker tripping on a canary token.
Most companies discover they've been breached way too late. Thinkst Canary fixes this: just 3 minutes of setup; no ongoing overhead; nearly 0 false positives, and you can detect attackers long before they dig in. Check out why our Hardware, VM and Cloud-based Canaries are deployed and loved on all 7 continents...
