Anthropic has just released the Opus 4.7 update with a fast mode, but early feedback from the expert community is far from positive.
Key Developments
Despite being promoted for its significant speed improvements, Opus 4.7 is still judged as not good enough to justify its extremely high operating costs. Many developers have stated they will skip this update. Meanwhile, alternative models like DeepSeek Flash are steadily asserting their position in practical applications thanks to a balance between performance and cost.
Why It Matters
The race between giants like Anthropic and emerging Chinese rivals (DeepSeek) is growing increasingly fierce. For Vietnamese users and businesses, choosing a model is not just about the brand but requires careful calculation of the return on investment (ROI). The lukewarm reception of an expensive model series like Opus 4.7 could accelerate the trend toward utilizing specialized, more cost-effective models.
