The guide defines gateways as reverse proxies that manage model calls for applications, reducing sprawl by consolidating provider credentials and enforcing rules like rate limits and guardrails. It breaks down the six-step request lifecycle—from input validation to response conversion—and warns that concentrating credentials in gateways creates a single point of failure, citing Microsoft’s August 2026 report on a LiteLLM compromise and Check Point Research’s October 2026 disclosure of two critical vulnerabilities in LiteLLM (CVE-2026-35029 and CVE-2026-59823), both patched in version 1.83.9. The guide also references outages, such as Cloudflare’s 2025 AI Gateway failure (97% error rate) and OpenRouter’s 2026 incidents caused by caching dependencies.\n\nPerplexity’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.","keyPoints":["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"],"whyItMatters":"The guide clarifies how teams can secure and optimize LLM gateways, addressing a growing pain point as organizations scale AI usage across multiple providers.
