## Code Arena

Code Arena is built for developers who want evidence rather than marketing claims when choosing a coding model. Instead of reading benchmark tables, you prompt multiple frontier models with the same request, watch them construct web apps and sites in real time, and then judge the output on accuracy, logic, and code quality. The 'battle' format mirrors the popular blind-comparison leaderboard approach, adapted specifically for software generation tasks.

The platform is designed to handle multi-file projects rather than single snippets, so the comparisons reflect the messy reality of real development work: routing, component structure, styling, and state management all have to hold together. Results are surfaced through a leaderboard so you can see which models are consistently favoured by the community over time.

Because the tool is free to use and browser-based, it works well as a quick sanity check before committing a paid subscription or API budget to a particular model, and as a way to keep a finger on the pulse of how fast the coding-model landscape is moving.

**Pricing & Plans:** Free to use; no paid tier is advertised on the product page. Related enterprise/API offerings from Arena may be priced separately.

- **Model battles:** Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
- **Real-time app building:** Watch models construct web apps and websites live, so you can see process and output, not just the final file.
- **Multi-file generation:** Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
- **Community leaderboard:** Track which coding models accumulate the most wins over time to identify consistently strong performers.
- **Free browser access:** Run comparisons directly in the browser without installing anything or paying for credits.

**Strengths:** Free, no-signup barrier for quick comparisons; Tests full multi-file projects, not just isolated snippets; Live battles reveal model behaviour, speed, and failure modes; Leaderboard aggregates community signal over time

**Limitations:** Battles are subjective and depend on the prompts you write; Not a full IDE replacement for day-to-day development; Leaderboard results can shift quickly as new models ship

## 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
