TextSynth offre un’API REST e un playground per accedere a modelli linguistici, di immagini, voce, trascrizione, traduzione ed embedding.
TextSynth is a model-access platform that exposes large language models and other generative AI models through a REST API and an online playground. The site presents text completion, chat, translation, image generation, speech generation, speech-to-text transcription, and embeddings as supported workflows.
The service is built around multiple named engines, including Mistral, Llama, Gemma, Stable Diffusion, Whisper, Parler-TTS, and BGE-Large-EN-v1.5. The documentation notes that TextSynth uses custom inference code to deliver faster inference on standard GPUs and CPUs, and that the servers are located in France.
The homepage says the basic service is free but rate limited, with an option to pay a small amount per request for unlimited usage. The documentation requires an API key for REST access, and the playground provides a browser-based way to try supported completion models.
Run text completion requests against engines such as Mistral 7B, Llama 3.1 8B Instruct, Gemma 3 27B Instruct, and Llama 3.3 70B Instruct. The API supports prompt input, stop strings, streaming output, multiple completions, and sampling controls like temperature, top-k, and top-p.
Use the chat endpoint for conversational workflows with supported chat models. The product site presents chat as one of its main model-access modes alongside text completion and translation.
Translate text with the MADLAD400 7B engine, which is described as supporting multilingual translation across about 400 languages.
Generate 512×512 images from English prompts with Stable Diffusion. The API documentation exposes a text-to-image endpoint for this workflow.
Convert speech to text with Whisper Large v3 or generate speech with Parler-TTS v1. The platform also lists embeddings through BGE-Large-EN-v1.5 for RAG-style workflows.
Build applications that need generated text, with control over prompt length, sampling, stop strings, streaming responses, and multiple completions from the same prompt.
Prototype chat assistants, Q&A tools, or translation features using the supported API endpoints and the named chat and translation engines.
Add image, speech, transcription, or embedding capabilities to a product through the same platform rather than integrating separate vendors for each modality.
Use the playground to test prompts and compare model behavior before wiring requests into an application.
TextSynth provides access to large language, text-to-image, text-to-speech, and speech-to-text models through a REST API and a playground. The documentation also covers text completions, chat, translations, embeddings, tokenization, image generation, transcription, and speech synthesis.
Authentication requires an account and an API key, which is sent in the `Authorization: Bearer YOUR_API_KEY` header for REST API requests.
The basic service is free but rate limited. The site also says users who want no limitation can pay a small amount per request, with pricing information referenced on the site.
The servers are located in France.
The playground includes model choices for text completion and related tools, while the API documentation lists engines such as Mistral 7B, Llama 3.1 8B Instruct, Gemma 3 27B Instruct, Llama 3.3 70B Instruct, Stable Diffusion, Whisper Large v3, Parler-TTS v1, and BGE-Large-EN-v1.5.
