openai/gpt-chat-latest · winner B · 8:1 · permalink

Side B introduces substantial new infrastructure: an extensible external URL foundation with a GitHub resolver, new UI actions and write commands for system ingests, resolver cooldown state, URL normalization improvements, recursive garden browsing enhancements, and extensive unit/browser tests. Side A is a focused bug fix that correctly changes rank highlighting to be computed per ranking group instead of globally and adds regression tests, but its scope and long-term architectural impact are much smaller.

openai/gpt-5.3-chat · winner B · 5:1 · permalink

Side B introduces a substantial new external resolver system (GitHub integration, SystemIngest pipeline, UI actions, and normalization logic) with end-to-end functionality and tests, adding durable capabilities. Side A mainly fixes ranking highlight logic by scoping gradients per group and improves vote UI display, which is valuable but comparatively narrow in impact.

openai/gpt-5.2-chat · winner B · 9:1 · permalink

Side B introduces a substantial extensible URL foundation: new external resolver infrastructure (GitHubResolver with API integration, cooldowns, SystemIngest write path), URL normalization changes (query stripping, YouTube/GitHub canonicalization), new UI actions, and broad tests including browser coverage. Side A is a small, targeted fix to ranking highlight gradients and minor vote UI tweaks with limited scope, whereas B adds enduring architecture and cross-cutting functionality.

~anthropic/claude-sonnet-latest · winner B · 85:15 · permalink

Side B implements a substantial, cohesive feature (on-demand GitHub external resolver with a new system-ingest write path, cooldown state, URL identity normalization rewrite, and matching browser/unit tests) that adds real durable capability and fixes URL identity bugs across multiple modules. Side A is a focused but much smaller UI/CSS fix for vote-history slider highlighting, useful but narrow in scope and lasting impact compared to B's broader architectural additions.

~x-ai/grok-latest · winner B · 1:4 · permalink

B establishes lasting URL identity rules (strip query/fragment by default, GitHub and YouTube canonicalization), a SystemIngest path, and a working on-demand GitHub resolver with browser coverage—foundational product architecture. A is a solid, tested vote-highlight/polarity UX fix (per-group gradients, center-anchored history sliders), but it is narrower polish on existing vote UI rather than core extensibility.
