How to Cut AI Model Costs by 75% with Gemini AI's Implicit Caching
In this perspective, Sam Witteveen explores how implicit caching works, why it's exclusive to Gemini AI's 2.5 reasoning models, and how it can transform the way you approach AI-driven projects. From understanding token thresholds to using reusable content in your prompts, you'll uncover practical strategies to optimize your workflows and reduce expenses. Whether you're managing repetitive queries, analyzing extensive datasets, or seeking long-term solutions for static data, this feature offers a seamless path to efficiency. The potential to save big while maintaining high performance isn't just a possibility—it's a reality waiting to be unlocked. Gemini AI Cost Savings What Is Implicit Caching?
Implicit caching is an advanced functionality exclusive to Gemini AI's 2.5 reasoning models, including the Flash and Pro variants. It identifies repeated prefixes in your prompts and applies discounts automatically, streamlining workflows without requiring user intervention. This makes it particularly effective for tasks involving repetitive queries or foundational data.
For example, if your project frequently queries the same base information, implicit caching detects this redundancy and applies a 75% discount on token costs. However, to activate this feature, your prompts must meet specific token thresholds: Flash models require a minimum of 1,024 tokens.
Pro models require at least 2,048 tokens.
These thresholds ensure that the system can efficiently process and cache repeated content, making it especially beneficial for high-volume tasks where cost savings are critical. When to Use Explicit Caching
While implicit caching is ideal for dynamic and repetitive queries, explicit caching remains a valuable tool for projects that require long-term storage of static data. Unlike implicit caching, explicit caching involves manual setup, allowing users to store and retrieve predefined datasets as needed.
For instance, if you're working on a project that involves analyzing a fixed set of documents over an extended period, explicit caching ensures consistent access to this data without incurring additional token costs. However, the manual configuration process may require more effort compared to the automated nature of implicit caching. Explicit caching is particularly useful for projects where data consistency and long-term accessibility are priorities. Cut Your Gemini AI Model Costs By Up To 75 %

This approach not only minimizes token usage but also enhances the overall efficiency of your queries.
Gemini AI's 2.5 models are specifically optimized to handle large context windows, making them well-suited for tasks involving substantial inputs such as documents or videos. However, it's important to note that while text and video inputs are supported, YouTube videos are currently excluded from caching capabilities. Testing your specific use case is essential to ensure compatibility and to fully use the system's capabilities. Strategies for Cost Reduction
To maximize savings and optimize workflows with Gemini AI, consider implementing the following strategies: Design prompts with reusable content at the beginning to take full advantage of implicit caching.
Test caching functionality to ensure it aligns with the specific requirements of your tasks.
Use explicit caching for projects that require consistent access to static datasets over time.
Ensure your prompts meet the minimum token thresholds for Flash and Pro models to activate caching features effectively.
By adopting these practices, you can significantly reduce API costs while maintaining high levels of performance and efficiency in your AI-driven projects. Understanding Limitations and Practical Considerations
While implicit caching offers substantial benefits, it is important to understand its limitations. This feature is exclusive to Gemini AI's 2.5 reasoning models and is not available for earlier versions. Additionally, YouTube video caching is not supported, which may limit its applicability for certain multimedia projects.
To address these limitations, it is crucial to evaluate your specific project requirements and test the caching functionality before fully integrating it into your workflows. Refining your prompt design and using the system's ability to handle large-scale inputs can help you overcome these challenges and maximize the potential of implicit caching. Maximizing the Value of Gemini AI
Gemini AI's implicit caching feature for its 2.5 reasoning models represents a significant step forward in cost optimization. By automatically applying discounts for repeated prompt prefixes, this functionality simplifies token management and delivers substantial savings. Whether you're processing repetitive queries, analyzing large documents, or working with video inputs, these updates provide a practical and efficient way to reduce expenses.
With strategic implementation and careful planning, you can cut your AI model costs by up to 75%, making Gemini AI a more accessible and cost-effective tool for a wide range of projects.

New Focus Friend app wants to help users reclaim their attention
Hank Green's new app, Focus Friend, has surged to the number one position on Apple's free app chart, outperforming ChatGPT, Google, and Threads. The app is an ADHD-friendly focus timer designed to help users reclaim their attention and gamify productivity by blocking distractions. It features a customizable 'bean' character that knits rewards when users stay focused, but drops its needles if attention is lost. Users can trade the bean's knitted items for decorations to customize its room, encouraging healthier screen time in a Tamagotchi-style format. Launched in July, the app's popularity exploded this week following increased social media promotion by Hank Green and his brother, John Green.

The new technology for prosthetic legs that could reduce NHS waiting lists by 50%
A new technology could reduce NHS waiting lists for prosthetic legs by half, a study has found. The software personalises prosthetic leg fittings based on data from previous patients. The data-driven fittings for below the knee prosthetics were, on average, as comfortable for patients as those created by highly skilled prosthetists, the NHS trial suggested. Technology developed by Radii Devices and the University of Southampton is hoping to halve the number of clinical visits for the fitting from an average of four to two using the software. The new technology is built to provide a personalised 'socket' using data from other fittings and a 3D scan of the residual limb to immediately generate a basic design. The CEO and founder of Radii Devices, Dr Joshua Steer, said analysing hundreds of previous sockets allowed them to 'identify trends' between different patient characteristics. 'We can then scan a new patient's residual limb and generate a personalised design recommendation based on features that have been successful for similar patients in the past,' he explained. The results of an NHS trial published on Friday in JMIR Rehabilitation and Assistive Technology suggest the new designs are on average as comfortable as those created by a prosthetist. Nineteen sockets were made for 17 participants, as two participants were double amputees, and all bar one of the sockets were above the 'NHS comfort score target', the Radii Devices CEO said. Of those 19 sockets, six of the new designs were reportedly more comfortable than normal prosthetics, while five were less and eight were very similar. Prosthetic sockets are personalised to ensure they are comfortable and functional, as they need to bear a person's body weight without damaging limb tissue or creating discomfort. Traditionally, a prosthetist makes a plaster cast of the leg and reshapes it to produce a socket which achieves the right balance, producing trial versions before settling on a definitive one. Radii Devices says the NHS currently tries to deliver a prosthetic in four clinical visits roughly a month from their first appointment, while the new system can aim for a 'gold standard' of two appointments. Alex Dickinson, Professor of Prosthetics Engineering at the University of Southampton – who helped to develop the new method, acknowledges that it has limits. He said: 'Only a highly skilled prosthetist can identify things like bone spurs and neuromas, and know how to tweak designs to avoid causing pain or damage at these sensitive areas. 'We developed the data-driven socket design approach to save prosthetists' time by giving them a solid base to work from so they can use their expertise where it is most valuable, in making precise adaptations tailored to their patients' specific needs. 'The method effectively helps prosthetists to learn from each other.' Another co-author, Professor Maggie Donovan-Hall, said it was 'surprising and encouraging' that the data-driven sockets performed so well in a test designed as a 'worst case' scenario where they received no additional input from prosthetists. Nearly 100 people have now had a prosthetic leg designed this way, across multiple centres in the UK and the USA. The study has now moved into its final stage where the new software is developed alongside clinicians to see how it can be best incorporated into their practices.

US Defense Department to buy cobalt for up to $500 million
Aug 21 (Reuters) - The U.S. is seeking to procure cobalt worth up to $500 million for defense stockpiles amid the country's move to boost its critical mineral supplies. Companies have been scrambling to source rare earths after China imposed restrictions, leading to a 75% drop in rare earth magnet exports from the country in June and causing some auto companies to suspend production. U.S. President Donald Trump in March invoked emergency powers to boost domestic production of critical minerals as part of a broad effort to offset China's near-total control of the sector. In July, Reuters reported that the White House tapped a former mining executive, David Copley, to head an office at the National Security Council focused on strengthening supply chains. According to the tender document published by the U.S. Department of Defense and the Defense Logistics Agency (DLA) on Wednesday, they are looking for offers for alloy-grade cobalt of about 7,480 tonnes over the next five years. Cobalt, mostly imported by the U.S., is used in batteries, a component in nickel superalloys for high temperature sections of jet engines and industrial gas turbines, among others. However, the defense department was seeking offers from only three companies - units of Vale SA in Canada, Japan's Sumitomo Metal Mining and Norway's Glencore Nikkelverk. The document also said the purchase amount can range from between $2 million and $500 million in the five-year period.
