## Countless.dev

Countless.dev addresses a practical problem for anyone building with AI: model choices multiply quickly and each provider publishes specs in its own format. The site gathers models from OpenAI, Anthropic, Google and many other providers into a single comparison surface, so you can look at input and output token costs next to context window, modality support, vision, embeddings, image generation, transcription and text-to-speech in one view.

Beyond plain tables, the tool offers a pricing calculator that lets you estimate what a workload will actually cost at a given volume, a head-to-head "versus" view for comparing two models directly, and benchmark-oriented views including a Pareto frontier that highlights models offering the best trade-off between capability and price. That mix suits both quick day-to-day lookups and more deliberate model-selection work.

The project is free to use and open source, which means it is community-friendly and transparent about how data is structured. Because provider pricing and model line-ups change frequently, treat the numbers as a starting point for comparison and confirm current rates with the provider before committing. It is most useful to developers, indie builders, product managers and anyone evaluating which model to route a feature through.

**Pricing & Plans:** Free to use, and the project is open source. The site itself does not charge for model comparison or the pricing calculator; any costs you incur are the model provider's own API fees.

- **Side-by-side model comparison:** View models from many providers in one interface, lining up pricing, context limits, modalities and capabilities.
- **Pricing calculator:** Estimate real-world cost for a workload by plugging in token or request volumes against current model rates.
- **Versus mode:** Put two models head to head to see exactly where one beats the other on price and features.
- **Benchmarks and Pareto frontier:** Explore capability-and-price trade-offs, with a Pareto view that surfaces models offering the best value for a given performance level.
- **Feature coverage beyond text:** Compare support for chat, embeddings, image generation, audio transcription, text-to-speech and vision across models.

**Strengths:** Free and open source, with no account needed to browse; Aggregates many providers so you avoid visiting each pricing page separately; Calculator and versus views turn raw price tables into decision support; Covers non-text capabilities such as embeddings, image, audio and vision

**Limitations:** Model line-ups and prices change fast, so listings can lag provider announcements; Feature depth depends on how each provider documents its models; It is a comparison and reference site, not a playground for actually running prompts
