LMOps is a comprehensive stack designed for launching production-ready applications that facilitate monitoring, model management, and additional features. Portkey serves as an alternative to OpenAI and similar API providers. With Portkey, you can efficiently oversee engines, parameters, and versions, enabling you to switch, upgrade, and test models with ease and assurance. You can also access aggregated metrics for your application and user activity, allowing for optimization of usage and control over API expenses. To safeguard your user data against malicious threats and accidental leaks, proactive alerts will notify you if any issues arise. You have the opportunity to evaluate your models under real-world scenarios and deploy those that exhibit the best performance. After spending more than two and a half years developing applications that utilize LLM APIs, we found that while creating a proof of concept was manageable in a weekend, the transition to production and ongoing management proved to be cumbersome. To address these challenges, we created Portkey to facilitate the effective deployment of large language model APIs in your applications. Whether or not you decide to give Portkey a try, we are committed to assisting you in your journey! Additionally, our team is here to provide support and share insights that can enhance your experience with LLM technologies.
