Azure AI Translator plans
| Plan | Price | What it covers |
|---|---|---|
| Free (F0) | $0 | Up to 2 million characters/month combined across text translation, detection, dictionary, transliteration, and Custom Translator training; no SLA. |
| Standard (S1), Text Translation | $10 / 1M characters | Pay-as-you-go standard neural text translation; ~half Google Cloud Translation's API rate. |
| Document Translation | $15 / 1M characters | Asynchronous whole-document translation preserving layout across formats like PDF, DOCX, PPTX. |
| Custom Translation | $40 / 1M characters | Translation served by a customer-trained domain-specific model. |
| Custom model training | $10 / 1M source+target chars (capped $300/training) | One-time cost to train a Custom Translator model on your bilingual data. |
| S1 Commitment tiers | Volume discounts at 250M / 1B / 4B chars | Monthly commitment plans with progressively lower per-million rates for high-volume standard translation (excludes Custom Translation). |
- Output can feel overly formal with limited control over tone or style
- Older S2–S4 pay-as-you-go tiers were deprecated, narrowing flexible plan options

DeepL API plans
| Plan | Price | What it covers |
|---|---|---|
| API Free | $0/month | Up to 500,000 characters per month; full text and document translation API access, no cost. |

- Narrow language coverage (~30 languages) vs Google's 100+; quality and availability drop sharply for Asian, African and Indic languages
- Premium per-character pricing (~$25/M chars) is far costlier than LLM-based translation, a developer measured ~$4/hr vs under $0.01/hr for Gemini Flash
- Customer support and billing rigidity are recurring complaints (support rated ~4.2/5 on Capterra; reports of 'no compensation' for failures)
