Yes. We have dedicated guides for AI Chat, image generation, text-to-speech, speech-to-text, the AI coding assistant, translation, and many more. Each guide explains how to use the tool effectively and get the best results.
Full API documentation is available at the API docs page. It covers all endpoints, authentication, request/response formats, code examples in Python, JavaScript, and cURL, and information about available models.
The AI Glossary is a comprehensive reference of AI and machine learning terms explained in plain language. It covers everything from basic concepts like tokens and prompts to advanced topics like embeddings and fine-tuning.
No. The web interface is designed for non-technical users. Just type your request and the AI responds. Technical users can use the API for programmatic access, but it is not required for any of the 200+ tools.
For general tasks, start with the free self-hosted models like Qwen 2.5 7B. For complex reasoning, use Qwen2.5-72B or premium models like GPT-4o. For code, use Qwen2.5-Coder-32B. Browse the model directory on the apps page to compare all 346+ options.
Yes. Our blog includes prompt engineering guides for different tools. General tips: be specific about what you want, provide context, specify the output format, and iterate on your prompts to improve results.
Yes. Visit the open-source page for a complete list of every self-hosted model with its license, use case, and link to the source code. All our models use permissive licenses -- Apache 2.0, MIT, or BSD.
The integrations page links to setup guides for Slack, WordPress, Zapier, the embeddable widget, the Chrome extension, and the bookmarklet. Each guide includes step-by-step instructions and code examples.
Tokens are the universal currency on Free.ai. One token roughly equals 4 characters of English text. Every tool costs tokens -- check the tokens page for a detailed breakdown of costs per tool and information about free daily limits.
