Pixel Canary goes free in stealth on AI Gateway: with Next.js docs supplied, it passes 30 of 31 tasks
Synopsis
Vercel has opened Pixel Canary on AI Gateway under the model id stealth/pixel-canary, free for a limited time while it stays in stealth. The model is strong at coding, including building applications and refactoring existing code, and suits frontend development and mobile app design. On Next.js evals at baseline it ties GPT 6 Astra (high) at a 90.3% success rate, passing 28 of 31 tasks; with Next.js documentation supplied through AGENTS.md it passes 30 of 31 (96.8%), tying the top score in that setting. Scores use pass@4, where a task passes if any of up to four attempts succeeds.
Interpretation
Vercel has released a coding model called Pixel Canary on AI Gateway under the model id stealth/pixel-canary, free for a limited time during stealth, so developers can select it inside their coding agents. The model was not previously among the models callable through AI Gateway's unified API. The stated setup path is to run vercel ai-gateway setup, a command that detects installed agents, provisions or reuses an AI Gateway API key and configures their connection to the gateway, after which stealth/pixel-canary is selected in the agent's model configuration.
Pixel Canary is strong at coding, including building applications and refactoring existing code, and covers frontend development and mobile app design from responsive layouts and app screens to navigation and interactive components. These capabilities are shown through Next.js evals whose tasks cover App Router migrations, data fetching, image and font optimization, caching and view transitions. On Next.js evals at baseline, Pixel Canary ties GPT 6 Astra (high) at a 90.3% success rate, passing 28 of 31 tasks; with Next.js documentation supplied through AGENTS.md it passes 30 of 31, or 96.8%, tying the leaderboard's top score in that setting.
Perspective
The demonstrated scope is pass results on Next.js evals and the task types tied to frontend and mobile interface development. The stated next step is to run vercel ai-gateway setup to complete the connection, then select stealth/pixel-canary in the agent's model configuration.
The announcement states that ZDR is not available for this model and that prompts and responses sent through it may be used for training and model improvement; it also states that the model is in stealth and free only for a limited time.
