awesome-free-llm-apis
Lists third-party LLM inference providers (including model owners and inference hosting platforms) that advertise permanent free tiers, along with example model names and rough rate-limit/free-tier notes and links to each provider’s API key page. It does not itself provide an API; it is a curated catalog.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
No centralized service or secret-handling guidance is provided. Users must manage provider API keys themselves; repository contains links and limit information only. Security posture (TLS/auth/scopes) depends entirely on each listed provider’s implementation and the user’s integration practices.
⚡ Reliability
Best When
You need a curated starting list to evaluate free-tier LLM access across multiple vendors and you will directly integrate with each provider yourself.
Avoid When
You need a managed service with consistent contracts, a stable API surface, or formal guarantees (SLA, idempotency, retries, error formats) from this repository.
Use Cases
- • Quickly finding LLM providers with free/permanent tiers for experimentation
- • Selecting an inference endpoint/provider when you want OpenAI SDK compatibility (where noted)
- • Bootstrapping multi-provider ideas for routing/fallback strategies (manual setup)
Not For
- • A production-ready, single unified inference API
- • Guaranteed availability or stable rate limits (provider policies can change)
- • Automated provisioning via a single authentication flow or SDK
Interface
Authentication
No auth is provided by this repository itself; each listed provider uses its own API key/auth mechanism via the linked dashboards.
Pricing
This is a catalog of providers with free/permanent tiers; pricing and limits are not enforced/validated by a central service.
Agent Metadata
Known Gotchas
- ⚠ Repository is not an API; an agent must integrate directly with each provider’s own endpoints/auth
- ⚠ Rate limits and free-tier availability may change; some entries say limits are undocumented
- ⚠ Compatibility varies (notes indicate OpenAI SDK compatibility is assumed except where explicitly noted, e.g., Ollama Cloud)
