Anthropic just launched Fast Mode for Claude Opus 4.6a configuration that allows you to obtain model responses up to 2.5 times faster. Of course, it will also affect our pocket, since the price also multiplies. Although right now this is an experiment aimed at professionals who need speed in critical tasks, it is also a move that we are starting to see more and more: monetizing AI tools with incremental improvements with what is already in place. And of course, if this reduces that margin between expenses and income of its operations, better and better.
What Anthropic has announced. Fast Mode is neither a new model nor a trimmed version of Opus 4.6. It is the same intelligence, with the same reasoning capacity, but configured to prioritize speed of response over cost efficiency. According to the companyoffers 2.5 times faster responses while maintaining the same model accuracy. At the moment it is available in the testing phase for Claude Code users who have the additional use activated, and also on platforms such as Cursor, GitHub CopilotFigma or v0.
The hit to the pocket. While Opus 4.6’s Standard Mode charges $15 per million input tokens and $75 per million output tokens, Fast Mode multiplies those fees: $30 input and $150 output for contexts under 200,000 tokens. In longer contexts, the output rises to $225 per million tokens. Anthropic is offering a 50% discount until February 16, but we’re still talking about a significant increase. The bill especially skyrockets if you activate Quick Mode mid-conversation, as it charges full price for all the previous context.
Who does it make sense to? Anthropic says that Fast Mode is designed for interactive work where latency matters more than cost. Real-time debugging, fast code iteration, urgent fixes before a deadline. Situations where waiting breaks the workflow. According to the official documentationit doesn’t make sense for long standalone tasks, batch processing, or jobs where the budget is tight. If Claude is going to spend 30 minutes refactoring code in the background, paying more for speed doesn’t add anything.
The signal that sends the market. Fast Mode is not just a premium option. It’s Anthropic testing how far its professional clients are willing to go to achieve fluency. And by the way, sending a message: improvements in speed and user experience are going to cost more and more. The company needs to close the gap between what it spends on computing and what it makes, and it’s doing it faster than its customer base needs to be faster on computing. Fast Mode is billed directly as additional usage, completely skipping the fees included in subscription plans.
Between the lines. Anthropic’s move fits into a broader trend. AI models are reaching a level of capability where “revolutionary” improvements are increasingly rare. What remains are incremental adjustments: a little faster, a little more context, slightly more precise responses. But those settings require massive infrastructure and face. So companies in the sector are trying new ways to monetize what they already have. In this case, charge much more to do the same thing, only faster. It is making performance profitable as a premium service.
The speed trap. “Speed is addictive”, counted Civil Learning in his Medium article. Once you experience a model that responds instantly without losing reasoning ability, going back is frustrating. Anthropic knows this. Fast Mode doesn’t just sell speed, it sells the ability to maintain flow during intense programming or debugging sessions. And once you get used to it, it’s hard to give it up.
And now what. Fast Mode is a research preview, meaning both features and pricing are subject to change. Anthropic plans to expand access to more API clients, but for now it keeps it under control. The key will be to see how many professionals are willing to pay that extra price on a sustained basis.
