## 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

## PromptHero

PromptHero started life as a gallery where people could look up prompts for image models and see the exact text that produced each result. That archive is still at the centre of the product, and it has grown to cover video models, language models and newer image engines. You can filter by model, style or trending categories, open any creation to inspect its prompt and parameters, and copy it into your own workflow.

Over time the site has expanded into an actual creation tool. After signing in you can write a prompt, pick a model from a wide catalogue and generate images or videos on PromptHero's own infrastructure, keeping your results private or publishing them to the community. A credits system governs how much you can generate, and unused credits roll over rather than expiring.

PromptHero is also a learning resource. Its Academy section, model directory and prompt collections are aimed at people who want to understand prompt engineering rather than just copy a string of text. The platform is independently operated and is not affiliated with or endorsed by Midjourney, OpenAI, Stability AI or any other model vendor it references.

**Pricing & Plans:** Freemium. A free account gives limited daily generations at standard speed with public results. Starter is about $19/month and Pro about $29/month on monthly billing, both including a monthly credit allowance, private generations, all models and faster queues. One-off credit packs (roughly 1,000 credits for $59 and 2,000 for $99) never expire, and annual billing often runs a two-months-free promotion.

- **Millions of searchable prompts:** Search and filter a large library of community prompts by model, style or category, and see the exact text behind each result.
- **Built-in image and video generator:** Create images and videos on-site with models including ChatGPT Image, Midjourney, FLUX, Nano Banana, Seedream, Veo and Sora.
- **Model directory and comparisons:** Browse documented AI image, video and language models in one catalogue to decide which engine fits your task.
- **Private generations and rollover credits:** Paid plans keep your output unlisted, and unused generation credits accumulate instead of expiring each month.
- **Academy and prompt guides:** Structured lessons and prompt-writing references for anyone moving from copying prompts to writing their own.

**Strengths:** Very large, well-categorised prompt archive with exact prompts visible; Generation across many models in a single interface; Private generations on paid tiers and credits that never expire; Free tier is genuinely usable for testing

**Limitations:** Free tier output is public and limited to a small daily quota; Credit consumption varies a lot by model and resolution; Interface is dense, with a lot of navigation for new users; Prompt quality is community-driven and inconsistent
