| Lựa chọn | Miễn phí gì | Thẻ | Điểm cần lưu ý |
|---|---|---|---|
| Deepgram Free $200 Credit | $200 | Không | Credit is tied to the Pay As You Go plan; billing switches to pay-as-you-go once the $200 credit is spent. |
| Speechmatics $100 Free Credit | $100 | Không | The $100 sign-up credit lasts 12 months and service pauses once it reaches zero; adding a card switches the account to pay-as-you-go. |
| AssemblyAI Free Credits | $50 | Không | Free tier caps streaming at 5 new streams per minute (vs 100/min paid), and LLM Gateway usage is not covered by the credits; the credits do not expire. |
| Gladia Free Credits | Free credits | Không | One-time credit that expires one year after signup, with no monthly reset; once used you must top up or upgrade to continue. |
| Groq Free Tier | Free tier | Không | Rate limits apply at the organization level and are tight (e.g. 30 RPM and 1K RPD on many models); the docs caution limits may change and exceptions exist. |
| Scaleway Generative APIs Free Tier | 1,000,000 tokens | Không | Free Tier applies to your most expensive tokens first; once exceeded, per-token billing starts with a 1,000-token minimum billing unit. |
| Sarvam AI Free API Credits | Free credits | Không | Rate limits are enforced per account across all keys (60 req/min for most APIs on Starter), and the credits are denominated in INR. |
