TextSynth, available within the Playground, is an AI-driven text completion tool that leverages large language models. It provides access to a variety of models, each tailored to specific linguistic needs. These models encompass GPT-J, a robust 6-billion-parameter model for English, Boris, a fine-tuned adaptation of GPT-J catering to the French language, GPT-NeoX, an imposing 20-billion-parameter model, and CodeGen-6B-monotop-k.

With TextSynth, users can input their text, and the neural network will promptly generate a contextually relevant completion, selected at random. The tool affords flexibility by allowing users to fine-tune model parameters, such as adjusting the temperature and specifying the maximum number of tokens.

Moreover, TextSynth comes equipped with pre-loaded examples, spanning a spectrum of categories like English-speaking Unicorns, Question-Answer exchanges, C-programming, Cooking instructions, Linux, Game of Thrones, HTML, insights into The Election, and even enigmatic Area 51.

For added convenience, users can choose to start with a template, be it a letter of motivation or the spark of an article idea. TextSynth enriches the text completion experience, offering diverse models and customizable parameters to suit your linguistic creativity.
