HHG for TranslatePress extends TranslatePress with best-in-class AI translation engines. Pick from four engine families instead of a single provider.
Supported Translation Engines:
Google Gemini AI
Powered by Google’s latest Gemini models. Choose from Flash-Lite (fastest & cheapest), Flash (balanced), Pro (highest quality), or 3 Flash Preview (cutting edge). API key from Google AI Studio.
OpenAI Compatible Platform
A universal engine supporting seven OpenAI-compatible API providers through a single, unified interface:
- OpenAI — GPT-4o Mini, GPT-4o, GPT-4.1, o4-mini, GPT-4 Turbo
- Azure OpenAI — Bring your own deployment endpoint
- Groq — Ultra-fast inference with generous free tier (Llama 4, Mixtral, Gemma)
- Together AI — Open-source model hosting (Llama 4, DeepSeek V3, Qwen3)
- OpenRouter — Multi-provider routing (access OpenAI, Anthropic, Google models)
- Ollama — Run locally, zero API cost (Llama 3.2, Qwen3, Mistral, Gemma 3)
- Custom — Any OpenAI-compatible endpoint you provide
Each platform preset includes curated model suggestions, platform-specific descriptions, and automatic API configuration. The model input supports both free-form text entry and one-click suggestion chips — type any model name or click to select.
DeepSeek AI
DeepSeek V4 Flash for fast, affordable translations and V4 Pro for professional-grade quality. Optimized with thinking disabled for faster throughput and lower cost.
ZhiPu AI GLM
Six translation strategies: General, Paraphrase, Two Step, Three Step, Reflection, and Chain of Thought. Choose speed or depth depending on your content.
Key Features:
- Industry / Domain Description — Describe your site’s context once (industry, tone, terminology rules) and it’s injected into every translation request for consistent, accurate output across all engines
- Three-layer context system — Sliding-window surrounding strings, page-level key term extraction, and industry prompt for terminology consistency
- Parallel async translation — All chunks dispatched simultaneously via cURL multi-handle for maximum speed
- Two-round retry logic — Failed strings automatically retried in a second pass with lower temperature for maximum completeness
- Intelligent caching — 30-minute transient cache per chunk for instant repeat translations
- Adaptive chunk sizing — Chunk size auto-adjusted based on average string length per page
- Platform-aware configuration — Timeout, temperature, and chunk size tuned per model family via heuristic detection
- Native TranslatePress integration — Settings panel styled to blend seamlessly with TranslatePress’s own UI, with smooth CSS transitions
- Code security — All inputs sanitized, outputs escaped, nonces verified, SSL enforced, following WordPress best practices
