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
Fireworks AI
Pros
- + DeepSeek R1 Fast reached 80-95 output tokens/sec in my low-batch tests, close to the vendor's 90 tok/s serverless figure
- + Grammar-constrained decoding on DeepSeek V3 returned schema-valid JSON on all 200 extraction calls in my batch
- + LoRA SFT on a 7B-class model went from dataset upload to deployable adapter in under an hour, served at base-model pricing
- + Training price card is fully public: $0.50/1M tokens (LoRA SFT, <=16B) up to $10.00/1M (>300B), DPO double
- + On-demand GPU pricing is published per hour (H100/H200 $8, B200 $13, B300 $15) with zero charge for start-up time
Cons
- - Open models only — my scanned-forms extraction task needed a frontier fallback Fireworks does not offer
- - Same model prices differently across Standard/Priority/Fast paths, and third-party trackers disagree with the vendor blog
- - DeepSeek R1 model card lists serverless as unsupported while a Fast serverless deployment exists — documentation contradicts itself
- - Self-serve stops at shared serverless: R1 fine-tuning, QAT, region pinning and enterprise rate limits are sales-gated
- - Shared-serverless latency is load-dependent by the vendor's own statement, so demo numbers are not an SLA
