Vercel AI Gateway

🧭 Aggregators (one key, many providers) · no card · live — last verified by a probe on 2026-09-17 · vercel.com · back to the whole list

What you get

One OpenAI-compatible endpoint for 360+ models, with $5 of gateway credits included every month and five language models that never touch the credit

Free models

laguna-s-2.1, ling-3.0-flash-fin

Limits, in the vendor’s words

$5 of gateway credit a month at provider list rates, renewed monthly, with lower per-model rate limits and no BYOK; buying credits ends the monthly free credit. A handful of language models are priced 0 in and 0 out and never draw on the credit — Laguna S 2.1 Free and the Ling 3.0 Flash Fin, Sante and VL rows, each with and without its -free suffix, on 2026-09-12. Mind the suffix: poolside/laguna-s-2.1 without it costs $0.10/$0.20 per 1M tokens

Callable ids: poolside/laguna-s-2.1-free, inclusionai/ling-3.0-flash-fin, inclusionai/ling-3.0-flash-fin-free, inclusionai/ling-3.0-flash-sante, inclusionai/ling-3.0-flash-sante-free, inclusionai/ling-3.0-flash-vl, inclusionai/ling-3.0-flash-vl-free
Note: every id listed is priced 0 in and 0 out and draws nothing from the $5 credit; any other Free-Tier-eligible model spends it. Zero-priced ids come and go within days, so a new one waits two weeks for the Models column. spacexai/grok-stt also shows a zero but is speech-to-text billed per second of audio. The same key serves the Anthropic Messages format at https://ai-gateway.vercel.sh, which Vercel’s docs give as Claude Code’s ANTHROPIC_BASE_URL with ANTHROPIC_API_KEY empty
