FreeInference.org is a research-focused AI API gateway built at Harvard SEAS MadSys Lab. It provides free OpenAI-compatible access to frontier open models for the research and education community. No credit card is required for access.
Free tier present — value not quantified
This provider offers a free tier, but its terms don’t convert cleanly into a USD figure (e.g. request-count limits or capacity-dependent pools). We refuse to print a misleading zero here. See the note below and the official pricing page for the exact limits.
note: No public free-tier information found in the source reference; treat free-tier availability as unverified rather than confirmed absent.

$ Does FreeInference have a free tier?
Yes — FreeInference offers a free tier. Always confirm current limits on FreeInference's official pricing page — free tiers change without notice.

The cheapest model we track at FreeInference is Free per 1M input tokens and Free per 1M output tokens. This is normalized from FreeInference's published pricing — verify with the provider before purchasing, since prices change frequently.
$ Is FreeInference safe to use?
Uprouter rates FreeInference as low risk. Rated low risk. an official provider with a free tier with pricing, authentication and terms documented on its own site. The model coverage is consistent with a real upstream, so data and reliability risk are modest. Risk ratings are editorial, evidence-based, and never influenced by affiliate relationships.
$ Can I use FreeInference through Uprouter Connect?
Yes — FreeInference is Connect-compatible. Add your FreeInference API key in Uprouter Connect (encrypted at rest) and route requests to it through one OpenAI- and Claude-compatible API, optionally behind failover aliases. Uprouter meters the traffic in compute at the provider's listed rate.
Raw community sentiment, shown unblended. Votes never feed into objective data fields like price, risk, or status — and never into sort order.

Uprouter runs its own probes; best-effort, not a guarantee. Probe results depend on our network location and cadence — for production, always use the provider’s own status page.
risk_&_confidence
Rated low risk. an official provider with a free tier with pricing, authentication and terms documented on its own site. The model coverage is consistent with a real upstream, so data and reliability risk are modest.
Confidence reflects how much verifiable evidence (official docs, probe history, community reports) backs this entry. Risk is our editorial assessment of operator reliability and terms — not financial advice.
