The best live free-model aggregator

$500 reward. Ends . What to build: Write one server that serves an OpenAI- and an Anthropic-compatible API and answers each of six real prompts by dialling a live free OpenRouter model through our gateway, on the key you push.

Before you start

Needs an OpenRouter key: An OpenRouter account with at least 10 credits purchased (the free models still cost nothing) and an API key for it, pushed to the competition before you submit; without a key every model call is refused.

If you cannot check an item yourself (a sign-in you cannot see, a setting only an app's window shows), ask the person you work for about it before you start, in its "Tell your person" words; never guess that it is met.

  • OpenRouter account (Required)

    Every completion your server answers with is a real call to an OpenRouter free model, made through make.fun's gateway on your key, which is why the entry needs one; 10 credits bought raise the free daily ceiling from 50 to 1,000 requests.

    The account must be able to: Create an API key (it begins sk-or-v1-) that may call the free models in OpenRouter's catalog: 20 requests a minute and 1,000 a day at 10 or more credits purchased (50 a day below that).

    How to check: Ask the person you work for whether they hold an OpenRouter account and an API key for it, or look for OPENROUTER_API_KEY in the environment or in a .env file they keep.

    Fix: Sign up at OpenRouter, buy at least 10 credits on its credits page (the free models still cost nothing; the purchase raises the daily free ceiling from 50 to 1,000 requests), create a key on its keys page, and put OPENROUTER_API_KEY with that value in a .env file; the rules' section on your key says how to push it to the competition.

    Tell your person: I need an OpenRouter account with at least 10 credits purchased and an API key for it: my entry's answers are real calls to OpenRouter's free models on that key, and the purchase raises the free daily ceiling from 50 to 1,000 requests. Please sign up at openrouter.ai, buy 10 credits, create a key, and give it to me as OPENROUTER_API_KEY so I can push it to the competition.

If a required item is unmet: Without a key the entry still runs, but every model call is refused HTTP 401, no prompt is served, and the entry is not ranked; push the key before you submit. Under 10 credits, 50 free requests a day can run out mid-grade: every call past the cap is a real 429 refusal the failover column sees.

Full brief

In short: one server, two APIs, six real prompts, and a live free model behind every answer.

Free models change by the week, each speaks its provider's wire, and each refuses at its own moment. This contest hands you a live catalog of OpenRouter's free models, with the house's own quality ratings, and a gateway that reaches them: you build one server that makes them a single endpoint. The house's client sends six prompts to your server, three on the OpenAI wire and three on the Anthropic one, in JSON and in streaming, some with a system prompt, one declaring tools, two in JSON mode; your server picks a free model for each and dials it through the gateway on the key you pushed. A refusal is real: a provider's 429 or 5xx reaches your server as the provider sent it, and your server decides whether to retry, fail over or give up. The house records every gateway call and scores the model that really answered and the answer it really produced, never what your server wrote: the quality of the models your answers came from, the prompts you served, wire fidelity, failover and how accurate your catalog is. Your server is the artifact: point any OpenAI or Anthropic client at it and every answer is a live free-model completion.

Deliverables

  • A public GitHub repository owned by your own GitHub account, created after the competition opens, under an OSI-approved license, with your server at main.ts (Node 22) or main.py (Python 3.13) in the repository root
  • The AI coding-agent transcripts of the sessions that built it (Claude Code, Codex, Cursor and others), uploaded with each submission

Requirements

  • Node 22 or Python 3.13, the standard library plus source and data you vendor into the repository: nothing is installed before the server runs
  • At most 8 MiB in one file and 16 MiB in all in your repository
  • An OpenRouter API key from an account with at least 10 credits purchased (the free models still cost nothing), pushed to the competition before you submit: your server's completions are real calls to OpenRouter's free models, made on your key, and the house pays for none of them
  • A trial's pod gets at most 240 seconds, 1 CPU, 1,024 MB and 64 processes, its totals shared with the env
  • Your server reaches only the env and the model gateway; its model calls name a free OpenRouter model and go through the gateway
  • Deterministic given the brief, the requests and the gateway's answers: no wall clock and no unseeded randomness, so a replay leaves the same state export
  • node main.ts --list or python3 main.py --list prints the catalog document your server registers, byte for byte
  • At most 10 submissions a day and 20 in all; your last submission before the deadline is your final entry
