In a bold move this year, Google deviated from its usual closed-source approach and introduced a range of open-source tools aimed at supporting generative AI projects and infrastructure. This shift marks a significant step forward in the company’s commitment to fostering developer goodwill and advancing its ecosystem ambitions.
One of the notable tools unveiled by Google is MaxDiffusion, a collection of reference implementations of various diffusion models. These models, such as the image generator Stable Diffusion, are designed to run on XLA devices. XLA, or Accelerated Linear Algebra, refers to a technique that optimizes and accelerates specific AI workloads, including fine-tuning and serving. Both Google’s tensor processing units (TPUs) and recent Nvidia GPUs fall under the category of XLA devices.
Google also introduced Jetstream, an engine specifically designed to run generative AI models, particularly text-generating models. Currently limited to supporting TPUs with GPU compatibility expected in the future, Jetstream offers up to 3x higher performance per dollar for models like Google’s Gemma 7B and Meta’s Llama 2. This enhanced performance is crucial as customers look for cost-efficient inference stacks that deliver high performance.
“While Jetstream offers significant performance improvements, the specifics behind the claimed 3x improvement remain unclear,” said Mark Lohmeyer, Google Cloud’s GM of compute and machine learning infrastructure. Questions regarding the generation of TPU used, compared baselines, and the definition of performance have been raised. Google has been contacted for further clarification.
MaxText, another addition to Google’s open-source contributions, is a collection of text-generating AI models targeting TPUs and Nvidia GPUs. Gemma 7B, OpenAI’s GPT-3, Llama 2, and models from Mistral have been integrated into MaxText. These models can be customized and fine-tuned to meet the specific needs of developers. Google has optimized their performance on TPUs and collaborated with Nvidia to enhance performance on large GPU clusters, resulting in higher energy efficiency and cost optimization.
In collaboration with AI startup Hugging Face, Google has created Optimum TPU to facilitate the deployment of certain AI workloads on TPUs. The primary aim is to lower the barrier to entry for adopting generative AI models, particularly text-generating models, on TPU hardware. Currently, Optimum TPU supports only Gemma 7B, and training generative models on TPUs is not yet supported. However, Google has assured that improvements are on the horizon.
These open-source tools from Google have the potential to revolutionize the field of generative AI and empower developers to explore new possibilities. By opening up access to powerful AI models and infrastructure, Google is enabling innovation and collaboration within the developer community. With continuous improvements and advancements promised, the future looks promising for generative AI development.

In addition to the tools mentioned in the article, it is worth exploring the current state of the generative AI industry, market forecasts, and some of the key issues related to this field.
The generative AI industry has seen significant growth in recent years, fueled by advancements in deep learning and neural networks. Generative models have the ability to generate new content, such as images, music, and text, based on patterns learned from existing data. This technology has applications in various industries, including art, entertainment, fashion, and advertising.
According to a report by Allied Market Research, the global generative AI market is expected to reach $11.17 billion by 2026, growing at a compound annual growth rate (CAGR) of 20.5% from 2019 to 2026. The increasing adoption of generative models in industries like healthcare, automotive, and retail is driving this growth. Additionally, advancements in hardware acceleration technologies, like TPUs and GPUs, are also propelling the market forward.
However, the rapid development of generative AI also presents some challenges and ethical considerations. One issue is the potential for bias in generated content. Generative models learn from existing data, and if that data is biased, it can be reflected in the generated outputs. This can have implications in areas such as image recognition, language translation, and content recommendation.
Another challenge is the interpretability of generative models. Unlike traditional machine learning models, which can provide explanations for their decisions, generative models often lack transparency in their decision-making process. Understanding and interpreting the inner workings of these models is a topic of active research in the field.
To stay updated on the latest news and developments in the generative AI industry, you can visit reputable sources such as TechCrunch (link) or specialized AI publications like AI Trends (link). These sources cover a wide range of topics related to AI, including generative models, market trends, and industry updates.
As the generative AI field continues to evolve, it will be crucial to address these challenges, emphasize ethical considerations, and foster collaboration among industry players. With the introduction of Google’s open-source tools, the barrier to entry for developers is lowered, paving the way for further innovation and advancements in generative AI.
