Portkey AI
Production AI gateway and observability platform that routes agent LLM calls across 1,600+ models with load balancing, fallbacks, retries, guardrails, and cost governance. Integrates natively with LangChain, LangGraph, CrewAI, and OpenAI Agents SDK so all model calls inherit routing and spend controls automatically. Logs and traces every request. Open-source gateway; managed cloud with usage-based pricing per recorded request.
Viable option — review the tradeoffs
You're building multi-agent systems that call different LLMs (OpenAI, Anthropic, local models) and need automatic failover, cost tracking, and request tracing without rewriting your agent code.
Sub-10ms latency overhead on average; 99.9999% uptime at scale (10B+ requests/month). You'll see detailed cost attribution per model/provider/user and full request traces. Canary testing and conditional routing work smoothly. The main quirk: you're adding a network hop, so ultra-latency-sensitive applications (sub-50ms SLAs) should test first.
You need to enforce spend caps, audit every LLM call for compliance (GDPR, HIPAA), and prevent runaway costs when agents make unexpected numbers of requests.
Cost limits are enforced hard (requests rejected if quota exceeded). Audit trails are comprehensive but add ~5–10% storage overhead. Compliance teams will appreciate the granularity, but you'll need to define policies upfront—there's no magic auto-detection of risky patterns.
You're running production agents across multiple cloud regions or on-prem and need to test new model versions (GPT-4o, Claude 3.5) without disrupting live traffic.
Canary testing works reliably and is genuinely useful for de-risking model upgrades. You'll see side-by-side metrics (latency, cost, error rate) for each variant. The limitation: you need to define success metrics yourself—Portkey doesn't auto-promote based on performance thresholds.
Pricing model opacity for high-volume workloads
Portkey uses usage-based pricing per recorded request. At 10B+ requests/month, the per-request cost compounds quickly, and pricing tiers aren't clearly published in search results. For cost-sensitive deployments (e.g., high-frequency batch inference), you need to request a custom quote, making budget forecasting difficult upfront.
Network latency adds up in latency-critical paths
Portkey sits between your agent and the LLM provider, adding a network hop. While sub-10ms on average, this can exceed your SLA if you're chasing <50ms end-to-end latency or running in high-latency regions. Test with your actual traffic patterns before committing to production.
Trust Breakdown
What It Actually Does
Portkey routes your AI agent calls across thousands of available AI models with automatic failover, cost limits, and request tracking. It works with popular agent frameworks so you get load balancing and spending controls without changing your code.
