Comparison of usage
How to use TextSynth?
TextSynth can be used via a REST API or through the playground on their website. Users can select the desired model and task (e.g., text completion, image generation) and submit requests. The basic service is free but rate-limited; users can pay for higher usage.
How to use Flatkey AI?
To use flatkey.ai, create an account on their platform and generate a single API key from the dashboard. Next, configure your local environment or AI tools (like Codex CLI or Claude Code) by running their one-line installation command or pointing your OpenAI-compatible client to the base URL (https://router.flatkey.ai/v1). Finally, monitor your multi-model usage, costs, and errors directly through the unified dashboard.
