## Models.dev

Models.dev exists to answer a very practical developer question: which model should I use, and what will it cost? The site organises every entry under a canonical identifier in the form provider/model, so the same model served by several providers can be compared directly rather than guessed at. Columns cover context window, maximum output, whether input and output are supported, reasoning, tool calling, structured output, temperature control, open versus closed weights, price per million tokens, and release and update dates.

Because model releases move fast, the catalogue is built to stay current, with sortable and searchable tables that let you scan by lab or provider and filter down to what matters. Entries include both closed flagship models and open-weight alternatives, making it useful for cost planning as well as capability research.

The project is open source and free to use, and it is intended to be consumed programmatically. Developers can pull the catalogue into their own tooling through a JSON API or a type-safe SDK, which makes it a practical backend for dashboards, routing logic, or internal cost calculators rather than just a reference page to browse.

**Pricing & Plans:** Models.dev is free and open source. It is a reference database, so the prices it lists are the per-million-token rates charged by the model providers themselves, not a fee for using the site.

- **Canonical model identifiers:** Every model uses a consistent provider/model format so the same model across providers can be compared directly.
- **Specification comparison:** Side-by-side context window, output limit, reasoning, tool calling, structured output, and temperature support.
- **Pricing transparency:** Input and output prices per million tokens listed alongside release and update dates.
- **Open and closed models:** Covers closed flagship APIs and open-weight models from many labs in one sortable catalogue.
- **Developer access:** Consume the catalogue through a JSON API or a type-safe SDK for your own tools and dashboards.

**Strengths:** Free and open source with no account required; Consistent canonical identifiers make cross-provider comparison reliable; Covers pricing, limits, and capabilities in one sortable table; Available as a JSON API and type-safe SDK for programmatic use

**Limitations:** It is a reference catalogue, not an inference or hosting service; Data quality depends on community and maintainer updates keeping pace with releases; Interface is aimed at developers and offers little guidance for non-technical users

## 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
