Background

By 2026, most model providers still offer some form of free access: new-user trial credits, permanently free small models, rate-limited free tiers, or self-hosted open models. The key distinction is what "free" actually covers: free quota, free rate, or free API with your own compute.

Steps

  1. Separate the three kinds of free: one-time trial credits (until exhausted), ongoing free tiers (rate-limited), and self-hosted open models (no API fee, but compute cost).
  2. Register on official developer platforms: sign up at each provider's developer console. Email verification is standard; some require a phone number or a payment method for identity verification (not necessarily a charge).
  3. Check the Billing or Usage page: confirm whether your account received trial credits and when they expire. Most trial credits last between 30 and 90 days.
  4. Apply for the free tier: some platforms offer a no-credit-card free tier with low rate limits, suitable for prototyping.
  5. Fall back to open models: if trial credits run out, run open models locally or on rented GPUs via Ollama, vLLM, or LM Studio. API cost is zero.
  6. Monitor usage: set spending alerts in the console so you don't silently roll into paid usage.

Caveats

  • Free credits are usually non-transferable and tied to verified identity. Farming credits across multiple accounts may violate terms of service.
  • Trial credits typically expire; don't stockpile them.
  • Free tiers often have rate and concurrency limits and are not production-ready.
  • Some free tiers require using your data to improve models; be careful with sensitive data.
  • Quotas and policies change frequently. Always check the official Billing page.

When to use

  • Individual developers building prototypes
  • Students and researchers running experiments
  • Small teams comparing options before buying

Summary

The logic of free tokens is trading limits for cost: limit time (trial), limit rate (free tier), or limit operational effort (self-hosting). Knowing which constraint you can accept is the key to choosing well.
