Portkey is an LLM gateway with strong observability and semantic caching. withConflux is a content-AI gateway — it dedupes by content hash, routes to the cheapest fitting detector, and caps spend.
An honest take — both are good tools. Pick by what you’re actually routing.

Drag the sliders to estimate your monthly bill on each — and what dedup saves.
Illustrative model. withConflux skips duplicate checks (dedup) and routes to the cheapest fitting provider; the competitor estimate assumes every check is billed. Real pricing varies — see the pricing page.
The three things that move the needle for content platforms.
Content-hash dedup means the same image or clip isn’t billed twice — often a third of the bill.
Managed routing sends each check to the lowest-cost provider that meets the need — no manual tuning.
Hard monthly caps return a clean 402 instead of a surprise invoice.
The questions people search before switching.
For content-AI workloads, yes. Portkey is an LLM gateway centred on observability and semantic caching for chat models; withConflux is built for content-detection vendors with content-hash dedup and cheapest-fit routing.
Semantic caching reuses similar LLM responses. Content-hash dedup recognises the exact same file (image/video/audio) and skips re-billing the detection call — the cost driver for content platforms.
Managed by default — we supply the vendor keys — with BYOK on request. Portkey is BYOK-first.
If you're routing LLM prompts and want tracing/caching, Portkey fits. If you're checking content at scale and want to stop paying twice for the same file, withConflux fits.
One gateway, dedup by default, cheapest-fit routing, one EUR bill.
