Why Activating by Provider Order Works Better

Official free tiers from model providers are currently the most stable and compliant source of free tokens. However, each provider has different open conditions, verification methods, quota refresh cycles, and rate limits. If you register in the order you discover them, you may get stuck in verification or find the API unusable after registration.

This article provides a repeatable activation order: start with providers that need no card and have simple verification, then handle those requiring phone/enterprise email/card, and finally handle providers with regional restrictions.

Steps

Step 1: Activate "Email-only" Providers

  1. Mistral AI: Go to console.mistral.ai and register with email. The free tier usually offers some trial credits and allows calling models like mistral-small without a card. Note free tier has rate limits, suitable for development testing.
  2. Cohere: Go to dashboard.cohere.com and register. The free Trial Key usually has monthly call quotas, suitable for text generation and Embed. Note Trial Key has per-minute/monthly request limits.
  3. AI21: Go to studio.ai21.com and register. The free tier offers trial credits, suitable for calling Jamba series models. Note credits expire after use and require application or upgrade.

Key point: These three usually only need email verification. After registration, send a request in the Playground to confirm the Key works.

Step 2: Activate "Phone or Enterprise Email" Providers

  1. Anthropic: Go to console.anthropic.com and register. Free tier usually requires phone verification, and some regions may require enterprise email. After registration, create an API Key in Console and test with lightweight models like claude-3-haiku. Note free credits have an expiration and usually refresh monthly.
  2. DeepSeek: Go to platform.deepseek.com and register. New users usually receive some tokens and need phone verification. Note granted credits have an expiration and become invalid after.
  3. Together AI: Go to api.together.ai and register. New users usually have a small amount of free credits for open-source models. Note free credits are pay-as-you-go after depletion.

Key point: Phone verification may be region-restricted. Use a common number to avoid virtual number rejection.

Step 3: Activate "High-speed Inference" Providers

  1. Groq: Go to console.groq.com and register. Free tier offers higher-speed inference credits, suitable for Llama series open-source models. Note free tier has per-minute request limits, suitable for low-concurrency testing.
  2. Fireworks AI: Go to fireworks.ai and register. New users usually have trial credits for various open-source models. Note credit validity and rate limits.

Key point: These free tiers suit latency-sensitive testing but not high-concurrency production.

Step 4: Handle "Regional Restriction" Providers

  1. Google AI Studio (Gemini): Go to aistudio.google.com. Free tier is available in some regions and usually allows calling Gemini models without a card. Note free tier has regional and rate limits.
  2. OpenAI: Go to platform.openai.com. Free tier is usually only for some new accounts and requires a card or specific conditions. Note free credits have an expiration.

Key point: For region-restricted providers, confirm your region is in the supported list before investing time in registration.

Notes

  • Quota refresh cycle: Most providers refresh free quotas monthly; a few offer one-time grants. Check Billing or Usage after registration to confirm.
  • Rate limits: Free tiers usually have RPM/TPM caps. High-concurrency scenarios need downgrade or queueing.
  • Regional restrictions: Some providers are not open to certain countries/regions. Check the supported list before registration.
  • Card requirement: Some free tiers still require a card. Confirm whether auto-charging occurs before binding.
  • Validity: One-time grants usually have an expiration. Use them first.
  • Compliance: Do not use multiple accounts to farm credits; violating terms may lead to account bans.

Use Cases

  • Individual developers: Use free tiers for prototyping and learning new models.
  • Small teams: Use multiple free tiers for model comparison to reduce upfront costs.
  • Teaching and experiments: Use free tiers for demos in courses or labs, avoiding procurement.
  • Model selection: Run benchmarks on free tiers before formal procurement.

FAQ

Q: What if free tier credits run out?

A: Wait for next month's refresh, apply for the provider's trial program, or switch to another free tier.

Q: Do I need to bind a card?

A: Some providers require it, some don't. Start with no-card providers, then handle card-required ones.

Q: Can free tiers be used in production?

A: Usually not recommended. Free tiers have rate and quota limits, suitable for testing and prototyping.

Q: How to confirm credits are credited?

A: Check the Usage or Billing page in Console after registration, or send a test request.
