Introduction

The realm of artificial intelligence has witnessed a race between tech giants, with Microsoft and Google vying for the top spot in developing cutting-edge large language models. However, despite their vast resources, a recently leaked Google memo reveals the remarkable breakthroughs achieved by the open-source community. Independent researchers from all corners of the world are dismantling barriers and propelling the future of AI. In this article, we will explore the contents of the memo, Delve into the realm of open-source model development, and share inspiring success stories. Join us as we uncover what it means to be a part of this AI Renaissance.

Understanding the Google Memo

The leaked memo, allegedly originating from Google, sheds light on the race between Google and OpenAI in developing large language models. Titled "We Have No Moat, and Neither Does OpenAI," the memo highlights the Lama model, initially developed by Meta (formerly Facebook) and unintentionally released as open-source. While the model weights were intended to remain private, they were leaked online within a week of their release to select academic and government partners. The leaked Lama model was rudimentary at first but underwent rapid advancements through a technique called Low Rank Adaptation (Lora). This approach utilizes linear algebra to factorize matrices, facilitating agile language model development.

The memo underscores that both Google and OpenAI primarily focus on building large language models, while acknowledging their potential capabilities. However, these models present challenges in terms of unwieldiness and slow iteration processes, hindering the implementation of other technological improvements. The memo concludes by recommending that Google should Seek to own the ecosystem by open-sourcing their own technologies. Interestingly, Meta aligns closely with this recommendation, given the open-source modifications made to the Lama platform, which is compatible with its internal usage.

Open Source Model Development

In this section, we will explore the intricacies of open-source model development. While the author does not directly contribute to the open-source community focused on large language models, they draw from their experience of working with open-source speech recognition models to shed light on the general process.

Developing open-source AI models necessitates data, training resources, and inference optimization. Acquiring suitable training data remains a challenge, although high-quality datasets like the Mozilla Common Voice project have emerged. However, acquiring raw data specific to training models is arduous. The resources of major companies allow them to hire people, Collect dialect-specific or language-specific speech samples, or leverage mechanical turkers to solve problems or rate data. Leveraging pre-trained models, which have undergone extensive training, offers an alternative for those lacking resources. Fine-tuning pre-trained models to specific purposes is a common approach.

In terms of compute resources, model training demands substantial power, often in the form of GPUs. Cloud-Based GPUs are expensive, making owning one's own hardware a more cost-effective option in the long run. By purchasing high-end GPUs and employing them in dedicated servers, the author donated training time to open-source projects while also utilizing them for personal adaptation of pre-trained models. The utilization of Lora optimization in training and weight adjustment allows for significant model improvements with relatively low compute resources.

Optimizing inference resources involves ensuring efficient model execution. Voice recognition, for instance, seeks to achieve local inference on low-powered devices, reducing computation time and memory requirements. The author Talks about building voice accessibility on a phone, initially employing a cloud-based recognition engine due to its CPU and memory requirements. However, advancements in the field now enable voice recognition to run locally on phones or even on devices as small as a Raspberry Pi. Developing user interfaces and integrating models into various applications is crucial to maximizing their usefulness.

Open Source Success Stories

In this section, we will explore success stories revolving around open-source AI models. Image generation through text-to-image conversion has witnessed extensive research and achieved significant breakthroughs, as exemplified by the Stable Diffusion and DALL-E models developed by OpenAI. These models were gradually fine-tuned and improved through contributions from developers worldwide. The emergence of painting in/out functionalities, allowing for image generation beyond existing boundaries, stood out as a remarkable outcome of the open-source community's efforts.

Voice recognition has also seen tremendous progress in the open-source realm. Previously, commercial products like Dragon Naturally Speaking dominated the market, but the open-source community leveraged the base product to develop academic and open-source models. This led to the availability of numerous models and frameworks such as PocketSphinx, Kaldi, DeepSpeech, and Flashlight. While commercial models still exist, they are either inexpensive or free. Companies like Google offer their Cloud Speech API for free in Chrome web browsers or charge nominal fees for API access. OpenAI's Whisper model provides language-specific speech recognition, accompanied by a CPP implementation for fast evaluation.

Large language models, a focal point of the Google memo, have witnessed extraordinary advancements in open-source development. The accidental release of the Lama model became a catalyst for rapid improvements. The open-source community harnessed techniques such as instruction tuning, quantization quality improvements, reinforcement learning with human feedback, and multimodality to foster the model's evolution. These collective efforts enabled the development of locally executable versions of gpt3, even on resource-constrained devices like laptops and phones. The progress achieved within such a short span is particularly striking, considering the extensive compute resources utilized by commercial models like gpt4.

The Power of Open Source

The examples of image generation, voice recognition, and large language models highlight the potential of open-source development. When sufficient interest and a strong academic foundation exist, open-source initiatives thrive. The distributed nature of the open-source community poses challenges in terms of individual accountability and the potential lack of control over model usage. Nonetheless, open-source development sidesteps issues that arise when a select few companies monopolize AI technologies. Open-source offers a democratic approach, encouraging tinkering and innovation. For those fascinated by open-source development, the book "Hackers and Painters" by Paul Graham is highly recommended.

The Dilemma of Control

While open-source development offers numerous advantages, concerns surrounding absolute model openness are valid. When models are freely available, they can be utilized for any purpose. This lack of control poses ethical, privacy, and security challenges. On the other HAND, centralized control by a limited number of companies also carries risks. Striking a balance between open-source development and responsible model usage remains an ongoing challenge.

Conclusion

The leaked Google memo provides valuable insights into the future of AI and the profound impact of open-source development on large language models. The open-source community's agility and resourcefulness have propelled them ahead, achieving milestones comparable to commercial counterparts. Open-source success stories in image generation, voice recognition, and large language models showcase the power of collaboration and grassroots innovation. While concerns surrounding model control persist, open-source development offers a compelling alternative to concentrated control. As technology enthusiasts, embracing the openness and potential of open-source AI development is both rewarding and exciting.
