Vercel AI Gateway

zero markup stated plainly, including on byok

$0 — usable on the free hobby plan#teams-already-deploying-

the most explicit no-markup commitment in the category, with the compliance controls you would need at scale metered on top.

vercel's pricing page states it directly: 'ai gateway charges no markup and no platform fee on tokens', and the docs extend that to byok. a million input tokens of claude sonnet 4.5 costs anthropic's list rate, deducted from a prepaid credit balance, with nothing added. the gateway works from a free hobby account, which makes it the cheapest serious starting point here alongside cloudflare.

the routing story is solid — one key across hundreds of models, automatic retry and failover to other providers, load balancing, and compatibility with openai chat completions, openai responses and anthropic messages formats, so most existing code points at it unchanged. embeddings, image and video generation ride the same credit balance.

the description above is ours, condensed from the ranking. pricing moves — check it on the vendor's own page before you rely on it.

we researched this category against vendors' own pricing pages and licence files. that is where this line comes from — not from the vendor, and not from anything they paid for.
