#85: This Week in Tech: OpenAI Launches ChatGPT-5, U.S. Backs $100M Open-Source Push, and Tesla Shutters Dojo Supercomputer
This Week in AI: OpenAI unveils ChatGPT-5, U.S. launches a $100M open-source AI initiative, and Big Tech doubles down on infrastructure spending. Meanwhile, Tesla shutters its Dojo supercomputer team, AI-linked layoffs spike, and early-stage AI startups secure millions as India’s Rajasthan sets an ambitious AI policy roadmap.
📌 TL;DR: This Week’s Headlines
OpenAI launches ChatGPT-5, introducing four variants with enhanced reasoning, coding, and multimodal capabilities
U.S. debuts $100M ATOM project to lead in open-source AI model development using 10,000 GPUs
White House urges Asian nations to avoid EU-style AI regulation in favor of flexible, U.S.-led governance
Microsoft, Meta, Amazon, and Alphabet escalate AI infrastructure spending, making it a top revenue driver
Tesla shuts down its Dojo AI supercomputer team, with leadership exits and staff moving to startup DensityAI
AI-driven layoffs rise 140% in July, with over 10,000 jobs cut directly due to automation
AI-native startups August, Lava, and Newton secure early-stage funding amid shifting VC norms
Rajasthan, India announces AI Policy 2025, pledging ₹1,000 crore for ethical AI adoption, skills, and innovation hubs
Over the past week, AI development and policy took several major leaps. On August 7, OpenAI hosted its “LIVE5TREAM” unveiling ChatGPT-5, which arrives in four configurations—standard, mini, nano, and chat—each with improved reasoning, code generation, multimodal support, and extended context windows. CEO Sam Altman likened the technology’s power to the Manhattan Project, even as he cautioned about a staggered rollout due to capacity constraints.
Two days earlier, the U.S. government announced the American Truly Open Models (ATOM) initiative, a $100M program to fund high-performance open-source AI models. Backed by figures from OpenAI, Hugging Face, Stanford, and Nvidia, the project aims to counter China’s advances in open-source AI and cement U.S. leadership. On the diplomatic front, White House tech adviser Michael Kratsios urged Asian governments to reject the EU’s risk-heavy AI Act, advocating for a more flexible, innovation-friendly regulatory model.
Industry investment continues to surge. Microsoft, Meta, Amazon, and Alphabet all disclosed massive new AI-related capital expenditures—Meta alone plans to spend up to $72B in 2025—underscoring a fierce race to own the AI compute stack. Tesla, meanwhile, made a surprise strategic pivot, disbanding its Dojo AI supercomputer team, once touted by Elon Musk as critical to achieving full self-driving capabilities. Team lead Peter Bannon is departing, while about 20 ex-Dojo staff have formed DensityAI, a chip and AI data center startup.
The broader AI market also reflected the technology’s disruptive force. July saw a 140% surge in AI-linked layoffs, with over 10,000 roles eliminated directly due to automation. In the venture space, AI-native startups continued to attract capital—August ($7M seed, legal-tech), Lava ($5.8M seed, agent-native payments), and Newton Research ($9M Series A, AI analytics) were among the week’s notable raises. According to Axios, AI efficiencies are enabling startups to reach Series A with 80% less seed capital than in prior cycles.
Globally, India’s Rajasthan unveiled its AI Policy 2025, committing ₹1,000 crore to ethical AI adoption, immersive tech incentives, and skills development, including a new AI Centre of Excellence.
The bottom line: This week showcased AI’s rapid advance across multiple fronts—major model launches, national-scale open-source projects, record infrastructure investments, strategic corporate pivots, and policy frameworks in both the U.S. and India. The AI race is intensifying, and the interplay between innovation, regulation, and disruption is accelerating.
🔮 AI & Big Tech
Launch of ChatGPT-5 – On August 7 at 10 AM PT, OpenAI hosted a “LIVE5TREAM” on YouTube, unveiling ChatGPT-5. CEO Sam Altman compared the model’s capabilities to the Manhattan Project, expressing both excitement and caution. A previously deleted GitHub post had revealed four variants—standard, mini, nano, and chat—featuring enhanced reasoning, code generation, multimodal support, and long-context capabilities. While the release was announced, Altman noted that the full rollout may face delays due to capacity limits.
Why it matters: GPT-5 introduces four variants—standard, mini, nano, and chat—offering enhanced reasoning, code generation, multimodal input, and long-context capabilities. It’s expected to significantly expand AI’s enterprise and consumer applications, though rollout could be slowed by capacity constraints.
ATOM Project launched to boost U.S. open-source AI: On August 5, the U.S. unveiled the ATOM (American Truly Open Models) initiative—backed by figures from OpenAI, Hugging Face, Stanford, and Nvidia—intended to reclaim leadership in open-source AI with a $100 million plan supporting development of powerful models using 10,000 GPUs.
Why it matters: Positions the U.S. to counter China’s growing open-source AI leadership while fostering transparency and accessibility in AI development.
U.S. urges Asia to reject EU-style AI “over-regulation”: Around August 5, White House tech adviser Michael Kratsios, speaking in South Korea, encouraged Asian governments to resist the EU's stringent AI regulatory model, advocating instead for flexible, U.S.-led governance and technology export strategies.
Why it matters: Signals U.S. efforts to build a coalition of countries aligned with its innovation-friendly AI governance model, challenging EU regulatory influence.
Big Tech continues ramping up AI investment: As of July 31, major tech firms—including Microsoft, Meta, Amazon, and Alphabet—are increasing AI spending, which is now a key driver for growth in search, advertising, and cloud revenues.
Why it matters: Higher spending on GPUs, chips, and data centers shows AI is now a primary growth driver in cloud, advertising, and productivity platforms—fueling competition for AI infrastructure dominance.
