ModelHubby

Free LLM APIs, actually verified.

Every “free LLM API” list goes stale the week it’s published. ModelHubby is a maintained registry: normalized records with real limits, signup friction, and data policies — every fact carrying provenance, checked by live probes, and versioned so you can see what changed.

Not another list

The registry treats provider facts like infrastructure, because your fallback chain depends on them.

Verified, not scraped

Three-level checks — record sanity, live model listings, and tiny real completions. When Google’s model list advertised a model that 404’d on chat, the probe caught it the same day.

“Free” ≠ frictionless

Card, phone, membership, time-to-first-key, and prompt-training policies are first-class fields. Filters never treat “unknown” as a pass.

Quota units, uncoerced

RPM, RPD, tokens, credits, neurons/day, concurrency — kept distinct, with the provider’s raw wording preserved next to parsed values.

Routing-ready

A local OpenAI-compatible gateway routes model: “auto” across your keys with health-weighted scoring, per-key cooldowns, and circuit breakers.

Provenance on every fact

Records cite their sources with trust tiers and check timestamps. Conflicts between sources are preserved and flagged, not silently resolved.

Versioned churn tracking

Monthly snapshots and material-change reports: which providers tightened limits, which models vanished, which policies flipped.

Featured free tiers

Ranked views, full records, and models for all 42 in the directory.
