Answer.AI

Answer.AI is an artificial intelligence research and development lab focused on turning advances in AI research into practical products and software. The company describes itself as a new kind of AI R&D lab that combines foundational research with hands on product development. It was publicly launched in December 2023 by Jeremy Howard and Eric Ries, with an initial $10 million investment from Decibel VC.

Rather than operating as a traditional AI chatbot or general purpose consumer assistant, Answer.AI works on the underlying technology, tools, and development methods that can make artificial intelligence more useful and accessible. Its work covers areas such as large language models, model training, retrieval, coding, open source software, AI education, and developer tools. The company publishes much of its research and software publicly, allowing developers and researchers to examine, use, and build on its work.

One of Answer.AI’s important areas of work is open source AI. In March 2024, the company released an open source FSDP and QLoRA system that allows models with up to 70 billion parameters to be fine tuned using two consumer GPUs with 24 GB of memory each. The project was designed to make advanced model training more accessible to smaller research teams and individual developers.

Answer.AI has also worked on efficient model fine tuning. Its FSDP QDoRA project focuses on making fine tuning more memory efficient while helping reduce the gap between parameter efficient fine tuning and full model fine tuning. This work is particularly relevant to researchers and developers who want to experiment with large language models without requiring extremely large computing infrastructure.

Another part of the company’s work is AI retrieval and language model tooling. Answer.AI has released projects including answerai-colbert-small and JaColBERTv2.5, which explore information retrieval and multilingual retrieval. It has also developed rerankers, an open source Python library intended to provide a simpler interface for different reranking approaches used in retrieval systems.

Answer.AI also develops practical developer tools. Claudette is an example of its work with language model APIs. It provides a higher level interface around Anthropic’s Claude API and includes features such as stateful conversations, image support, prefill, and tool use. The project is presented in a literate programming style, with its source code designed to explain how the library works.

The company has also developed FastHTML, a Python framework for creating interactive web applications. Answer.AI describes FastHTML as a way to build modern web applications in pure Python, with applications ranging from small prototypes to more complex production projects. Other projects include MonsterUI, FastMigrate, gpu.cpp, Cold Compress, nbsanity, and WebGPU Puzzles.

Education is another important part of Answer.AI’s work. In 2024, fast.ai joined Answer.AI, continuing the long standing goal of making artificial intelligence more accessible through practical education. The organizations also introduced How To Solve It With Code, an educational experience built around working with AI through small, iterative development steps.

Answer.AI’s Solveit platform extends this approach into an AI assisted development environment. Solveit is designed around what the company calls Dialog Engineering, where developers work with AI through short iterations rather than asking an AI system to generate a large application all at once. The platform can support coding, writing, research, system administration, and other problem solving activities.

The company’s approach is strongly connected to open source development and public research. Its website contains a large collection of technical articles, research discussions, software releases, and educational material. Several of its projects are explicitly released as open source, including tools for model training, retrieval, web development, GPU programming, and AI application development.

For developers and researchers, Answer.AI can therefore be useful as more than a single AI application. Its collection of projects provides software libraries, research implementations, educational resources, and experimental tools that can be used across different stages of AI development. Developers can explore projects through their documentation and source code, while researchers can follow the company’s published experiments and technical articles.

Answer.AI is particularly relevant for people working with Python, machine learning, large language models, retrieval systems, AI application development, and open source AI. Its projects can also be useful for students and educators interested in understanding how modern AI systems are built and applied.

One consideration is that Answer.AI is not a single all purpose AI assistant. Its offerings are spread across different research projects, software libraries, educational experiences, and products. Users looking for a simple chatbot or conventional productivity assistant may need to look at individual Answer.AI projects rather than expecting one unified application.

Overall, Answer.AI represents an R&D focused approach to artificial intelligence. Its work combines research, software engineering, education, and open source development with the goal of turning AI research into practical tools. Since its launch in 2023, it has published projects covering model training, retrieval, coding, web development, AI education, and developer tooling, making its website a useful starting point for developers and researchers who want to explore practical AI technology.

Pricing

Answer.AI does not present a single standard subscription price for the overall R&D lab. Its projects can have different access and pricing arrangements. Several software projects are open source and available for developers to use, while products such as Solveit and Plash have their own commercial models. Solveit uses usage based credits, while Plash currently advertises a $5 per month platform subscription plus usage charges.

Review

Answer.AI is particularly relevant to developers, researchers, and technically minded users who want to explore practical AI development rather than simply use a chatbot. Its combination of research publications, open source projects, developer tools, and educational resources provides a broad technical ecosystem. The main consideration is that the experience is project based, so users may need to identify the specific Answer.AI project that matches their needs.
