TextSynth AI is an online AI service platform that provides multimodal capabilities based on large language models, including text generation, image generation, and speech processing. Users can access via API or the online interactive interface.
The platform supports a range of text-generation models such as Mistral, Llama series, Gemma, and other modalities like Stable Diffusion for image generation and Whisper for speech-to-text.
There are two main ways: 1) sign up and use the online Playground for interactive testing; 2) as a developer, integrate features into your own apps by calling the REST APIs.
There is a free tier with rate limits. For higher usage or unlimited access, pay-per-request pricing applies; see the pricing page for details.
TextSynth is suitable for developers, researchers, content creators, and educators who need easy access to and integration of multimodal AI models for text, image, or speech tasks.
According to its documentation, servers are located in France, with privacy considerations built into the service design.
Playground is an online interactive space where users can test different AI models in real time, adjust generation parameters, and view results without coding.
Users can typically fine-tune parameters such as temperature, top-k, top-p, and maximum generation length to control randomness and style.
