Generative artificial intelligence, popularized by tools like ChatGPT, relies on massive computing power. Behind these increasingly powerful models lies a key component: the chip. Today, this reliance on semiconductors is becoming a major strategic issue for AI labs, governments, and manufacturers. In this context, OpenAI is reportedly now considering designing its own AI chip to better control its technology stack and reduce its dependence on third-party suppliers like NVIDIA1.
This ambition marks a turning point for Sam Altman’s company. By transitioning from a software developer to a hardware manufacturer, OpenAI could join the select group of companies capable of mastering algorithms, cloud infrastructure, and hardware components all at once. It’s a risky strategy, but one that highlights a global battle over technological sovereignty in AI.
Why does OpenAI want its own chip?
OpenAI currently relies almost exclusively on NVIDIA to train its large language models, including GPT-4 and GPT-5. H100 GPUs (and previously A100s) have become the cornerstones of modern AI. But this dependence poses a problem:
- Limited availability: these units are scarce, subject to quotas, and very expensive on a large scale.
- High operating costs: energy and financial expenses for infrastructure are skyrocketing.
- Customization constraints: OpenAI’s models have specific requirements that generic GPUs do not always meet optimally.
Developing its own chips would allow OpenAI to tailor the hardware to its own models, optimize performance, and reduce training times. This move is similar to Google’s development of its TPUs (Tensor Processing Units) or Amazon’s Inferentia and Trainium chips.
An already highly competitive market
The AI chip market is one of the most sought-after in the tech industry. In 2024, more than 80% of AI data centers worldwide were using NVIDIA GPUs2. But other giants have already staked their claim:
- Google has developed TPUs, which are optimized for its own TensorFlow models.
- Amazon Web Services offers its Trainium chips for training and its Inferentia chips for inference.
- Apple, through its M-series chips, equips its devices with built-in neural engines.
- Meta and Microsoft are also working on their own chips, particularly for data centers.
In this landscape, OpenAI’s entry as a future AI chipmaker raises questions: does it simply want to reduce its dependence on NVIDIA, or does it aim to become a full-fledged player in the hardware ecosystem, much like Apple in the smartphone industry?
The key role of Sam Altman and the spin-off projects
For several months now, Sam Altman has been simultaneously leading a fundraising effort estimated at $7 trillion to build a global supply chain for AI chips, from materials to manufacturing3. This project, which is separate from but possibly connected to OpenAI, aims to create a global semiconductor production capacity tailored to the needs of generative AI.
Rumors also suggest that OpenAI is in talks with several startups specializing in the design of innovative chips (Tenstorrent, Groq, Rain AI), as well as exploring partnerships with Asian and European manufacturers. By bringing design in-house, OpenAI may be aiming to speed up development cycles while maintaining control over the energy efficiency, security, and technological sovereignty of its models.
What are the implications for the AI ecosystem?
OpenAI’s decision to design its own chip raises several challenges:
- Vertical integration: OpenAI would control the model, the cloud (via Microsoft Azure), and the hardware.
- Ecosystem fragmentation: proprietary chips could limit interoperability and even hinder the adoption of open standards.
- Higher barriers to entry: only companies capable of designing both software and hardware would be able to remain competitive.
- Potential cost savings… but at the cost of a massive initial investment.
At the same time, this trend could prompt other players (such as Anthropic, Cohere, or Mistral) to form partnerships with hardware companies or develop their own chips, further intensifying the competition.
A global battle over silicon
The development of AI chips is not merely a matter of corporate strategy; it is part of a broader geopolitical battle over semiconductors. The United States, China, and the European Union are stepping up efforts to secure their production, supply chains, and intellectual property. Taiwan, with TSMC, remains a critical hub in this global supply chain.
In this context, every vertical integration initiative undertaken by a major AI player becomes a strategic move, aimed at reducing dependencies, optimizing performance, and positioning itself as an autonomous technological powerhouse.
Toward a more closed, proprietary model?
If OpenAI continues to develop its own chip, it could eventually offer a fully proprietary solution: chip, infrastructure, API, models… This scenario would resemble Apple’s, where control over the entire chain allows for extreme optimization but also limits transparency and openness.
This would raise questions for the scientific community, open AI researchers, and startups that use OpenAI’s models via API. Control over hardware strengthens a dominant position… but can also lead to isolation.
Toward end-to-end AI control: ambition or technological lock-in?
With this AI chip project, OpenAI is no longer just seeking to create high-performance AI models; it now wants to run them on hardware it controls. This drive to control the entire artificial intelligence value chain—from silicon to the cloud, including the algorithms—is redefining the balance of power in the global ecosystem.
It remains to be seen whether OpenAI will be able to meet this colossal technological challenge… without betraying the values of openness and transparency that first made it famous.
