Amazon To Test AI-Created Material For Carbon Capture In Data Centers

Amazon is stepping up its environmental efforts by testing a groundbreaking carbon-removal material for its data centers. The company, which is tackling the growing emissions linked to the artificial intelligence systems powering these centers, has partnered with Orbital Materials, a startup that used AI to design the innovative substance.

Jonathan Godwin, CEO of Orbital Materials, explained that the new material acts like an atomic-level sponge, with cavities precisely sized to capture CO2 without interacting with other elements. This targeted approach could be a game-changer in carbon filtration.

One of the appealing aspects of the new material is its cost-effectiveness. Godwin estimates that the material could account for just 10% of the cost associated with renting a GPU chip for AI training, significantly less than the price of traditional carbon offsets.

Meanwhile, the demand for energy in data centers is rising, as AI’s rapid development requires more power and cooling solutions. This surge poses a challenge for Amazon, which is committed to achieving net-zero carbon emissions by 2040.

Amazon Web Services (AWS), the world’s largest cloud provider by revenue, plans to begin piloting the AI-designed carbon removal material in one of its data centers starting in 2025. This initiative is part of a three-year collaboration with Orbital, which will also gain access to AWS’s technology and open-source AI tools for further development.

Howard Gefen, General Manager of AWS Energy & Utilities, stated that the partnership would promote sustainable innovation, but financial details remain undisclosed. Orbital, with offices in Princeton, New Jersey, and London, began its journey about a year ago by setting up a lab to synthesize AI-designed materials. The startup aims to work with AWS to test additional AI-generated solutions, addressing water usage and cooling requirements in data centers. Godwin co-founded Orbital, which currently employs 20 people and is supported by investors such as Radical Ventures and Nvidia’s venture arm. Before this, Godwin contributed to materials science work at Alphabet’s DeepMind until 2022.

OpenAI Brings Unlimited Text Chats To Free ChatGPT Users

Unlimited Text Conversations Roll Out

OpenAI is removing limits on text-based conversations for all ChatGPT users, following the platform’s recent milestone of surpassing one billion weekly users.

The update introduces GPT-5.6 Luna as the default model for Free and Go users, replacing GPT-5.5.

New “Think” Button For More Complex Questions

Alongside unlimited text chats, Free and Go users will gain access to a new “Think” button, allowing them to use additional reasoning power for more complex queries.

OpenAI noted that separate usage limits will continue to apply to file uploads, image generation, voice features and other multimodal tools.

Faster Responses For Paid Subscribers

The update also brings improvements for ChatGPT Plus and Pro subscribers. They will receive access to GPT-5.6 Sol, an upgraded model designed for everyday tasks such as web research, planning, writing, decision-making and answering questions. According to OpenAI, the model delivers shorter, more robust responses.

The company noted that this version is separate from the GPT-5.6 Sol model used in Codex and Work, which remains unchanged. Plus and Pro subscribers will also receive a new thinking slider, allowing them to adjust how much reasoning the model applies before generating an answer, depending on the complexity of the task.

OpenAI Reports Fewer Errors

According to OpenAI’s internal testing, GPT-5.6 Luna produces 62% fewer factual errors than GPT-5.5 Instant, while GPT-5.6 Sol reduces factual errors by 68%.

The updated GPT-5.6 Sol model is available to Plus and Pro users starting today. The remaining features for Free and Go users will roll out throughout the week, with unlimited text chats and the new Think button becoming available next week.
