How this task was evaluated

Results are ordered by this task's published score. API runs use one prompt and one completion; agent runs use a coding harness with tools and iteration. Inspect the execution method when comparing results.

Objective scores use the benchmark's execution checks. Judge scores use a vision panel's fixed rubric; the published score leaves out a model's own family. Missing values are labelled rather than treated as zero.

Read the brief

You are given a reference screenshot of a real marketing home page (the Banja home page hero). Reproduce it as faithfully as you can as ONE self-contained HTML file (`index.html`) that renders with no build step and no network calls (inline all CSS, no external fonts, scripts, or images). Match what the screenshot shows: - a very dark, near-black background (around #0a0a12) with a faint grid pattern, - a top bar with the word-mark "Banja" on the left (in a violet/purple accent), a centre navigation row with the links About, Services, Products, Case Studies, Lab, Contact Us, and a white rounded pill button on the right reading "Let us pitch to you", - a large centred hero heading on two lines: "WE BUILD" in white, then "PRODUCTS." in a violet-to-pink gradient (use a single <h1>), - a muted sub-heading reading: For founders who move fast. Idea to product in weeks, not months. with the phrase "Idea to product in weeks" emphasised in white, - two call-to-action buttons below: a solid white "START A PROJECT" button and an outlined "VIEW OUR WORK" button. Keep the colours, the centred layout, and the relative sizes close to the screenshot. Use plain, readable, accessible markup. The page must stay readable when the window is narrowed (responsive).
