Free volunteer queue, slow warning
AI Horde routes to volunteer-run workers through a priority queue, so latency is seconds to minutes, not the sub-second of hosted providers. The anonymous key 0000000000 runs at the lowest priority; register a free key at aihorde.net for higher priority. The provider uses a 120s timeout.
No tool calling info
AI Horde's OpenAI-compatible proxy does not support function/tool calling. The provider drops tools, tool_choice and parallel_tool_calls so a tool-using request still completes as plain chat instead of failing.
Usage is kudos; tokens estimated info
The proxy returns usage as {"kudos": N} with no token counts, and rejects max_tokens below 16 and a non-array stop. The AIHordeProvider normalizes the request (floors max_tokens, wraps stop) and synthesizes prompt/completion token estimates so analytics and savings math aren't zero.
Roster + context depend on online workers info
Model availability changes as volunteer workers come and go, so a listed model can be temporarily unserved. The effective context window is set by the worker (often 4-8K), not the model's native maximum.
Uneven quality warning
Output quality varies by worker and quantization, and some workers append template or instruction text after the answer. Best treated as free fallback capacity, not a primary model.

Use it

FreeLLMAPI is a self-hosted router you run yourself. Install it, paste in your free AI Horde key, and koboldcpp/Gemma-4-E4B-Uncensored-HauhauCS-Aggressive answers on an OpenAI-compatible endpoint at http://localhost:3001/v1. No credit card, no hosted middleman: your prompts and your provider keys never leave your machine.

Install the router (macOS, Linux, WSL)
curl -fsSL https://freellmapi.co/install.sh | bash
Install the router (Windows PowerShell)
iwr -useb https://freellmapi.co/install.ps1 | iex
Call koboldcpp/Gemma-4-E4B-Uncensored-HauhauCS-Aggressive with curl
curl http://localhost:3001/v1/chat/completions \
  -H "Authorization: Bearer freellmapi-your-unified-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "koboldcpp/Gemma-4-E4B-Uncensored-HauhauCS-Aggressive",
    "messages": [{"role": "user", "content": "Say hi in five words."}]
  }'
The same request in Python (openai)
from openai import OpenAI

client = OpenAI(
    base_url="http://localhost:3001/v1",
    api_key="freellmapi-your-unified-key",
)

resp = client.chat.completions.create(
    model="koboldcpp/Gemma-4-E4B-Uncensored-HauhauCS-Aggressive",
    messages=[{"role": "user", "content": "Say hi in five words."}],
)
print(resp.choices[0].message.content)

The router answers on /v1/chat/completions and every other OpenAI surface, plus the Anthropic Messages API, so existing clients need only a new base_url. Swap the model id for auto and the router picks the best free model that is still under its limits. Full reference: docs/api.md.
