Sir, Dario just dropped opus 5.5 and it beats GPT-6 astra at agentic coding on medium effort while being 80% cheaper… beats fable 5.1 on every benchmark… 30% faster than opus 5… and sir… they even raised the usage limits and gifted everyone a tibo style banked reset…

Anthropic and OpenAI simultaneously released new models, Opus 5.5 and GPT-6 Sol. Benchmarks indicate that Sol's primary advantage is cost, being half the price per token. Opus 5.5, however, uses significantly more tokens, with AA measuring around 119K output tokens per task compared to Sol's 31K, making Sol's cost per task approximately $1.06 for the entire index. The community is eager to see real-world performance and gather feedback on these new models.

This report uniquely compares the newly released Opus 5.5 and GPT-6 Sol, highlighting Sol's cost advantage at half the price per token, unlike other reports that focus on individual model performance.
