## Code Arena

Code Arena is a hands-on playground and leaderboard where you can pit leading AI coding models against each other on real web builds, comparing speed, accuracy, and logic in live side-by-side battles.

**價格與方案:** 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.

**優勢:** 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

**限制:** 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

## Upscale Image (Upscayl)

Upscayl is a web-based AI image upscaler that turns blurry, pixelated or low-resolution photos into sharper HD and 4K results. Upload an image, pick an enhancement mode and upscale factor, preview the result and download it in JPG, PNG or WEBP.

**價格與方案:** Upscayl uses credit packs: Mini at $10 (200 conversions, uploads up to 1000x1000px), Creator at $30 (800 conversions), Pro Pack at $50 (2,000 conversions) and Studio Pack at $100 (5,000 conversions), all one-time purchases paid via Dodo and with credits that never expire. Higher tiers raise batch size to 50-100 images and upload resolution to 4000x4000px. A free tier allows a few images per batch.

- **AI upscaling up to 8K:** AI models analyze the image and reconstruct detail to raise resolution while keeping textures and edges natural rather than artificially sharpened.
- **Multiple enhancement modes:** Purpose-built modes for standard photos, portraits, anime and art, face restoration and scratch restoration let you match the tool to the image.
- **Batch processing:** Upload up to 5 images at once on the free tier, with larger batches available on paid plans for high-volume workflows.
- **Extra editing tools:** Non-destructive cleanup tools include background removal, object removal, watermark removal, colorization, photo restoration and an AI photo editor.
- **Format choice and API:** Save your upscaled image as JPG, PNG or WEBP, and use an API with keys to integrate upscaling into your own apps.

**優勢:** Free tier to test before buying; Wide range of upscale factors from 1x up to 8x; Specialised modes for photos, anime, faces and scratches; Batch uploads and multiple output formats

**限制:** Free tier is limited, and high-volume work requires buying credit packs; Maximum upload resolution is capped below 4000x4000px on the entry plan; Only JPG, PNG, WEBP and ZIP are accepted, so other formats must be converted first; Output quality varies with the source image and chosen model
