Hello, students!
Claude’s new model, Opus 5.5, has been released, and we’re excited to share the news :)
Have you ever worked with Claude Code, supplemented your explanations several times, but still failed to get the desired result and ended up finishing the task yourself?
With this model, it would be a good idea to have it tackle tasks that didn’t go well before and compare the results.
And the speed has become noticeably faster. I’ve also switched everything I was running on fable 5.1 at work over to opus 5.5, and it feels much smoother. The quality of the answers also feels clearer and cleaner.
There are three changes worth noting in Anthropic’s official announcement.
Improved performance on complex coding tasks: It is said to have improved on lengthy, multi-file tasks such as migrations that modify an entire codebase and large-scale code reviews.
Speed and cost improvements: Compared to Opus 5, output generation is reportedly more than 30% faster, and execution costs for typical tasks with the default settings have decreased by approximately 40%.
More readable explanations: It is said to have been improved to present important information first and explain the results and reasons for changes in an easy-to-understand way.

When trying it yourself, start with a task whose outcome you already know. Give it a previously fixed bug or a feature that took several requests to complete, under the same conditions.
Comparing whether the results are correct, how much intervention is needed along the way, and whether it explains the reasons for its revisions convincingly will help you assess how useful it can be in your work.
You could also redo the exercises from the course using Opus 5.5. Try applying the process of organizing requirements, defining the scope of the work, and verifying the results as well :)
Then, I wish you all the best on your learning journey.
Thank you!
