An unverified Terminal-Bench 4.0 chart circulating on X shows GPT-6.1 Terra winning around the 50% score range at notably lower cost than GPT-6.1 Sol, GPT-6 Astra, and Claude Sonnet 5.5.

Claude Sonnet 5.5 still holds the top score (70%) at over $10 per task, while GPT-5.6 Terra underperforms. Commenters caution it's only a single benchmark; authenticity awaits official confirmation.
