AI Chip Startup Groq Secures $1.5 Billion Investment From Saudi Arabia

Groq, a U.S.-based AI semiconductor startup, has secured a $1.5 billion commitment from Saudi Arabia to expand its advanced AI chip delivery in the country. The startup, founded by a former Alphabet AI chip engineer, specializes in AI inference chips that optimize speed and execute commands for pre-trained models.

Groq already has a partnership with Aramco Digital, the tech arm of oil giant Aramco, through which they developed a key AI hub in the region in December. The investment will fund the expansion of Groq’s data center in Dammam, with the startup having obtained the necessary licenses to export its chips despite U.S. export controls.

The announcement was made at Saudi Arabia’s LEAP 2025 event, where the country also secured $14.9 billion in AI investments. One of the technologies supported by the Dammam Center is Allam, an AI language model developed by the Saudi government that operates in both Arabic and English.

In August, Groq raised $640 million in a funding round led by Cisco, Samsung, and BlackRock, bringing its valuation to $2.8 billion.

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.
