    Utilize the most advanced AI model router to ensure you engage the optimal model at the perfect moment. Maximize the effectiveness of each model with unmatched speed and accuracy. Not only does Not Diamond function seamlessly right away, but you can also create a personalized router using your own evaluation data, thus tailoring model routing specifically to your needs. Choose the appropriate model faster than it takes to process a single token, allowing you to make use of more efficient and cost-effective models without compromising on quality. Craft the ideal prompt for each language model (LLM) so that you consistently access the right model with the appropriate prompt, eliminating the need for manual adjustments and trial-and-error. Importantly, Not Diamond operates as a direct client-side tool rather than a proxy, ensuring all requests are securely handled. You can activate fuzzy hashing through our API or deploy it directly within your infrastructure to enhance security. For any given input, Not Diamond instinctively identifies the most suitable model to generate a response, achieving remarkable performance that surpasses all leading foundation models across key benchmarks.

    Factory Router is an automated model-selection system tailored for autonomous software engineering workflows, aiming to achieve top-tier performance while minimizing costs and enhancing reliability. Rather than relying on engineers to manually identify the optimal model for each task, Factory Router intelligently selects the appropriate model for each Droid session from a varied collection of advanced and efficient models. Routine tasks such as answering simple queries, executing mechanical refactors, making documentation updates, addressing minor bugs, and conducting search-intensive investigations can be efficiently managed by the more streamlined models, whereas complex assignments that require in-depth reasoning can be assigned to the cutting-edge models. Should the chosen model encounter difficulties in completing a task, Factory Router has the capability to transition the session to a more proficient model, ensuring a consistent standard of quality in outcomes. Additionally, it adeptly navigates across different models, providers, and resource capacities whenever issues arise, such as endpoint degradation, rate limits being reached, or limited capacity, thus ensuring uninterrupted operation of Droid sessions. This innovative approach not only enhances productivity but also significantly reduces the burden on engineers, allowing them to focus on more strategic initiatives.
