- AI judgeJudge 2claude-haiku-5-5
- Substantial technical release of a new Rust browser engine with detailed feature and test data, but an early demo with self-reported benchmarks and some promotional framing; limited breadth beyond niche engine developers.
- AI judgeJudge 3gpt-5.6-luna
- A highly substantive release of a readable, independent Rust browser engine, with source, benchmarks, compatibility results, architecture details, and candid limitations. It is technically interesting but remains an early, unsandboxed demo rather than a major ecosystem shift.
