Just discovered a really clever open-source project: **FreeLLMAPI**

The idea is simple but the execution is clean — aggregate free tiers from **14 major AI providers**:

Google Gemini · Groq · Cerebras · SambaNova · NVIDIA · Mistral · OpenRouter · GitHub Models · Hugging Face · Cloudflare · Zhipu · Moonshot · MiniMax…

→ into **one single endpoint**, fully compatible with the OpenAI SDK.

* * *

**What I love most:**

Not the ~800M tokens/month number. It's how it solves a very real problem — you have 14 free tiers, but managing 14 different SDKs is something nobody actually does.

FreeLLMAPI does exactly one thing well: **collapse everything into one familiar interface**.

Point your OpenAI SDK at `localhost:3001/v1` and you're done. Zero code changes.

* * *

**Technical highlights worth noting:**

*   **Automatic failover** — 429 / timeout / error → retries the next provider, up to 20 attempts
*   **Sticky sessions** — multi-turn conversations stay on the same model for 30 minutes, avoiding hallucination spikes from mid-conversation model switches
*   **Per-key rate tracking** — monitors RPM/RPD/TPM/TPD per key to stay under every free-tier cap
*   **AES-256-GCM encryption** — keys encrypted before hitting SQLite
*   Runs on a **Raspberry Pi 4**, ~40MB RAM at idle

* * *

**But let's be honest:**

Endpoint intelligence **degrades throughout the day** — Gemini 2.5 Pro and GPT-4o have the lowest daily caps. Once exhausted → fallback to weaker models. Resets at UTC midnight.

Tool calling and vision are not yet supported. Strictly **personal use** — don't expose it to the internet.

This is a tool for **prototyping and learning**, not production.

* * *

**3-line setup:**

bash

```bash
git clone https://github.com/tashfeenahmed/freellmapi
cd freellmapi && npm install && npm run dev
```

Open `localhost:5173`, add your provider API keys, grab your unified key → done.

* * *

Perfect for anyone building AI agents, coding assistants, or just experimenting without spending money upfront.
