Portkey
Pros
- + OpenAI-compatible endpoint at api.portkey.ai/v1 let me swap providers via a header change with no SDK rewrite
- + Fallbacks fired within the same request cycle in my fault-injection test — the client never saw the upstream failure
- + MIT-licensed gateway self-hosts free (12.8k GitHub stars); hosted Production starts at $49/month for 100K logged requests at time of writing (portkey.ai/pricing)
- + 40+ built-in guardrails apply one policy across every downstream provider instead of per-SDK rules
- + Developer tier is free forever and sufficient for prototyping: 10K recorded logs/month (portkey.ai/pricing)
Cons
- - Log-metered pricing climbs fast: at list, 10M recorded requests computes to roughly $949/month on Production (leanroute.dev, at time of writing)
- - Free Developer tier keeps logs only 3 days and stops recording after 10K logs — debugging history disappears
- - SSO, granular budget limits, and VPC deployment are Enterprise-only
- - May 2026 acquisition by Palo Alto Networks puts roadmap and pricing power in a security vendor's hands
- - Semantic caching and the observability dashboards are hosted-only; self-hosters get routing and guardrails alone
OpenAI API
Pros
- + Lowest false-call rate on my 250-case tool-use evaluation, including the deliberate no-call cases
- + Single account covers text, reasoning, image, audio, transcription, embeddings and agent tooling
- + Framework integrations were config-only where rival providers needed adapter code I had to maintain
- + Official pricing page documents wrinkles (residency uplifts, Fast mode rename) that others bury
- + Streaming response times were consistent enough over a week of monitoring that I stopped tracking them
Cons
- - Tool metering ($10/1k search calls, $2.50/1k tool calls) became about a fifth of my search-heavy prototype's bill
- - Entry rate limits are tight; my batch job triggered a 429 burst until spend tier rose
- - 10% uplift on regional data-residency and FedRAMP endpoints adds to an already premium price list
- - Specialised model lines (Rosalind trusted-access, cyber tier) assume institutional buyers
- - Catalogue churn makes third-party tutorials stale within months
