This is an addon for TranslatePress that adds AI-powered translation capabilities using modern Large Language Models (LLMs). It extends TranslatePress with four major AI translation engines:
- OpenAI (GPT-4, GPT-4o, GPT-3.5 Turbo)
- Anthropic (Claude 3.5 Sonnet, Claude 3 Opus, Claude 3 Haiku)
- OpenRouter (Unified access to 100+ AI models)
- DeepSeek (Best price-performance ratio for translations)
TranslatePress - LLM Translation Engines enables you to automatically translate your WordPress website content using state-of-the-art AI models. Instead of traditional machine translation services, you can leverage the power of:
- OpenAI's GPT models - Known for excellent understanding of context and nuance
- Anthropic's Claude models - Highly regarded for natural, human-like translations
- OpenRouter's unified API - Access to multiple AI providers (OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, and more) from a single interface
- DeepSeek - Exceptional translation quality at the lowest cost (~$0.14/1M input tokens)
The screenshot shows the Automatic Translation settings page where you can configure your AI translation engines.

| Provider | Model | Input/1M Tokens | Output/1M Tokens |
|---|---|---|---|
| DeepSeek | DeepSeek Chat | $0.14 | $0.28 |
| OpenAI | GPT-4o Mini | $0.15 | $0.60 |
| Anthropic | Claude 3.5 Haiku | $1.00 | $5.00 |
