Claude Opus 4.8 Released β Faster and Cheaper, Making Long-Form Work More Comfortable
What happened: Anthropic released "Opus 4.8," Claude's top-tier model. According to reports, the speed of its fast mode has improved significantly, and usage costs are lower than before.
Why it matters: Users can now choose how deeply the model thinks before answering (effort), making it easier to tune the balance of speed and accuracy to fit the task.
What it means: For reading through long documents or writing in Japanese, the perceived wait time and cost have improved. When you want the model to think things through carefully, raise the "effort" and use it accordingly.
