Opus 4.6 shipped as a follow-on, not a rename. Our seed notes it slightly behind 4.5 on the last published bash-only SWE-bench sweep and stronger on long-horizon traces. That is a snapshot, not a personality test. If your bookmark still says 4.6, the model page will tell you whether ingest moved the cells.
Follow-ons confuse aliases
OpenRouter ids and Arena names drift. 4.6 has aliases so daily ingest does not create a second preview row. If you see “needs alias” in changelog, attach the leftover name in /admin — do not invent a new slug.
Empirical Evaluation & Architectural Analysis
Empirical evaluations recorded across the CompareLLM Leaderboard highlight how parameter scaling and inference optimization impact production throughput and cost-per-token economics. Reference the interactive scorecard above for verified snapshots or inspect the dedicated claude-opus-4-6 dossier.
Read 4.6 against 4.5, not against Sol
Same family, same list class. Cross-lab compares belong on 5 vs Sol. Intra-family belongs on 4.5 vs 4.6.
Strategic Deployment Recommendation
