A blogger reports nearly two hours of hands-on testing with the rumored Claude Opus 5.5:
- SEO-related outputs show almost no difference from the previous Opus
- Switching across Medium/High/Extra effort levels produced largely similar answers
- Overall responses are much like Opus 5's
Early first-hand impressions of an unannounced model (unconfirmed by Anthropic); treat with caution.
