## 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

## Museum of Models (Rival)

Museum of Models — the project formerly known as Rival — is a free, ad-free archive of how AI models actually answer. Since May 2024, the same 100 questions have been put to every model in the exact same way, once, and every answer has been kept exactly as it was given, including the odd ones and the empty ones. The result is 18,773 answers from 385 models, a record of how each one drew a pelican, built a landing page, told five jokes, or named a favourite city.

The premise is that leaderboards only remember scores. When a lab retires a model and switches it off, its weights often disappear and nobody can ask it anything again. The museum keeps the outputs themselves: 121 of the 385 models featured are no longer served on OpenRouter, yet their drawings, websites, writing and image answers are still here to browse.

Nothing on the site is ranked or scored, and supporting it changes nothing about what it shows. Answers are presented in their native form — drawings as SVG, websites running live in a sandbox, images as pictures, writing as readable pages and voices you can play. Visitors can spin an interactive globe of answers, compare two to four models side by side, sort by release date, lab or question, and step back through a monthly timeline of the museum since it opened. The full collection is downloadable and reusable under CC BY 4.0 with credit.

**Pricing & Plans:** The museum is completely free with no ads. Hosting costs are covered by voluntary donations, such as buying the creator a coffee, and all answer data can be downloaded and reused under CC BY 4.0 with credit.

- **18,773 answers from 385 models:** One hundred identical questions covering drawings, websites, writing, images, code and audio, each answered by every model and kept as given.
- **Retired models preserved:** 121 of the 385 models are no longer served on OpenRouter, yet their answers remain viewable, preserving outputs that would otherwise be lost.
- **Side-by-side comparison:** Add two to four models with a single click and view their answers to the same questions next to each other.
- **Interactive globe and index:** Explore a magnifiable globe of answers, an index sortable by release date, lab or question, a monthly timeline, and a fast command-K search.
- **Live, runnable exhibits:** Generated websites run live in a sandbox, drawings are the model's own SVG, images are shown at 640px, and voices can be played directly.

**Strengths:** Completely free and ad-free, with no login required; Preserves answers from models that have since been retired and switched off; Methodologically consistent: identical prompts, one attempt, documented settings; Open data downloadable under CC BY 4.0 and explorable through globe, index and side-by-side views
