Opus 5.5

Anthropic's Opus 5.5 model has reportedly surpassed OpenAI's Astra (GPT-6), with users claiming it "wipes the floor with every other models right now." Released before GPT 6 Sol and Luna, Opus 5.5 is accessible via a $20 plan and offers significantly improved performance over previous Opus models. Its launch was noted for its understated marketing, contrasting with Astra's "AGI era" claims, leaving users impressed and curious about future Haiku 5.5 and Sonnet 5.5 releases.

Unlike the Astra release, Opus 5.5 launched without AGI claims, yet users report it surpasses all current models, including Astra, offering improved performance over prior Opus versions.
