OpenAI: The screenshot covers the core sign-in layout well: split branding panel, centered card, tabs, email/password fields, show/hide icon, remember/forgot, primary CTA, divider, and social buttons.

The visual design is clean, modern, and well-spaced with a coherent blue palette, though it feels fairly conventional. Overall craft is solid with no obvious broken elements, but the result is more polished-standard than distinctive or premium.

Google: The layout fulfills the visual requirements with a clean split-screen design. Visuals are professional but somewhat generic. Execution is solid, though it lacks strong distinctiveness.

Anthropic: The split-screen layout, branded panel (Nexus logo + value line), and a minimal sign-in card with email/password and a create-account link are present, but most of the brief is missing from view: no "or continue with" divider or social buttons, no remember-me/forgot-password, no show/hide password toggle, and only a barely-visible radial gradient rather than a real decorative SVG. Visually it is clean and the purple accent is coherent, but the card is sparse and undersized with a lot of empty white space, the right panel feels unbalanced, and there is no inline validation or strength-meter sho

OpenAI: The screenshot includes a basic split layout with branding, value line, and a sign-in card with email/password fields and a create-account link, but many required elements are not visible: decorative visual, validation states, password visibility toggle, loading state, divider/social login, remember/forgot controls, and create-account-specific fields/strength meter. The design is clean and usable but very plain, with large empty areas and little premium polish or distinctive detail.

Google: The layout meets basic requirements but omits key features like social logins, remember-me options, and decorative visuals. The overall aesthetic is generic, lacking the premium finish requested.
