https://github.com/WiegerWolf/ai-pricingI built this tool to solve a common problem: understanding the real cost of using different AI models at scale. It compares pricing and performance metrics across major AI providers, with interactive calculators for both Large Language Models and Speech-to-Text services.
What it does:
- Compares 20+ LLMs (GPT-4, Claude 3, Gemini 1.5, Groq, etc.)
- Shows Arena ELO scores, processing speeds, context sizes
- Calculates monthly costs based on token usage
- Compares STT services (Deepgram, AssemblyAI, OpenAI Whisper, etc.)
- Displays per-minute/hour pricing and free quotas
- Updates regularly with latest models and pricing
Technical details:
- No frameworks or dependencies, just vanilla HTML/CSS/JS
- Data stored in JSON files for easy updates
- Responsive design, works on mobile
- Keyboard navigation support
- Open source, MIT licensed
Example use cases:
- Calculate costs for different usage scenarios
- Compare model performance vs price
- Find models with free tiers
- Check real-time STT capabilities
- Verify context window limitations
The tool helped me choose providers for several projects, so I thought others might find it useful too. Feedback welcome!
