# Infron Free AI Models

> Selected :free model variants at $0 per token via Infron's OpenAI-compatible API

- Provider: [Infron](https://aifree.dev/provider/infron-ai)
- What is free: 1,000 requests/day
- Status: verified by a person on 2026-10-12
- Credit card: not required
- Sign-up: required
- For: Developers
- Resets: daily
- Claim at: https://infron.ai/docs/overview/free-models

## What you get

Access selected :free model variants (e.g. deepseek/deepseek-v4.1-flash:free) at $0.00 per token through Infron's OpenAI-compatible API, with 1,000 requests per day per account pooled across all standard free models.

## The catch

Standard :free models require a $5+ account balance (not consumed); free requests share one daily pool and run on a shared public pool without SLA.

## Limits

- 1,000 requests/day per account, shared across all standard free models, resets 00:00 UTC
- Standard free models require a $5+ balance (not spent; anti-abuse)
- New accounts start at $0 balance
- Default per-account rate limits still apply
- Free variants may route to different providers and run on a shared public pool without SLA

## Details

## Overview

[Infron](https://infron.ai) is a usage-based LLM router that offers selected model variants with a `:free` suffix at **$0.00 per token** — requests to free models never deduct from your credit balance. All models are served through a single OpenAI-compatible endpoint.

## Free Tier Quotas & Limits

- **Daily Allowance:** 1,000 requests per day per account, pooled across all standard free models combined (not per-model).
- **Reset Time:** Daily at 00:00 UTC.
- **Rate Limits:** Free model requests remain subject to Infron's default per-account rate limits.

## Key Free Models

- Free variants are identified by a `:free` suffix, e.g. `deepseek/deepseek-v4.1-flash:free`. The full current lineup is available from the `/v1/models` endpoint (filter for `:free`).
- A limited-time promotion of `qwen/qwen3.8-max-preview:free` (1M-token context, up to 64K output tokens, tool calling, JSON mode, streaming) ended July 28, 2026.
- Free variants may route to different providers than their paid counterparts and are served from a shared pool with no SLA; the lineup changes over time.

## Eligibility

- Standard free models require an account balance of **$5 or more** — held, not spent, as an anti-abuse requirement. Requests fail with an error if the balance falls below $5.
- Credit top-ups incur a 5% + $0.35 platform fee per transaction.
