TextSynth

TextSynth is a platform that offers developers access to a variety of large language models, as well as models for generating images, converting text to speech, and transcribing speech to text. Utilizing advanced REST API services, TextSynth supports a wide range of applications including text completion, chat, translation, image generation, and speech transcription. Founded in 2020, it has positioned itself among early adopters of leading AI models, such as GPT-2.

The platform employs custom inference code to ensure efficient computations, which enhances speed and reduces costs on standard CPUs and GPUs. All servers are based in France, providing reliable access to AI services. Users can start with a free plan that allows limited access to the models, making it an appealing choice for experimentation and small projects. For users needing extensive access without limits, a Standard Plan is available that operates on a credit-based pricing system.

TextSynth's unique credit system allows users to pay for what they consume, with clear pricing based on input and output tokens. This approach ensures predictability in billing, reducing unexpected costs. Users can easily purchase credits via Stripe, with flexible options for payment in USD or EUR. Credits must be used within one year of purchase, effectively streamlining the budgeting process for project-based AI tasks.
