Key points
- Perplexity’s guide defines LLM gateways as reverse proxies managing model calls, reducing credential sprawl but concentrating security risks
- Check Point Research disclosed two critical LiteLLM vulnerabilities in October 2026, patched in version 1.83.9, with 97M monthly downloads
- Deployment options range from free open-source tools (LiteLLM, Bifrost) to paid managed services (Cloudflare, Portkey) with pricing starting at $50/month
Perplexity’s guide covers deployment options—ranging from in-house scripts to managed services like Cloudflare AI Gateway or Portkey—and pricing, noting costs start at around $50/month or as a percentage of credit purchases (e.g., OpenRouter’s 5.5% markup). It also details vendor-specific tools, including Perplexity’s open-source Numbat for agent inspection and AWS Bedrock AgentCore Gateway for multi-provider inference. The guide emphasizes guardrail hooks (e.g., Portkey’s before/after hooks) and failure policies to mitigate risks.
