It introduces advanced reasoning capabilities, allowing users to engage in complex problem-solving by breaking down questions into manageable tasks. Users can activate “Think” mode to view step-by-step reasoning or “Big Brain” mode for more demanding inquiries.
Grok-3 is integrated with X (formerly Twitter), providing real-time data access and enabling dynamic interactions. It is available to X Premium+ subscribers for $40 per month, with a new “SuperGrok” subscription tier offering additional features for $30 monthly.
DeepSeek-R1
DeepSeek-R1 is an open-source AI model developed by the Chinese startup DeepSeek, launched in January 2025. It is designed for advanced reasoning, mathematics, and coding, positioning itself as a strong competitor to models like GPT-4. Due to U.S. export restrictions on high-end AI chips, DeepSeek trained the model using older Nvidia H800 GPUs, employing a cost-efficient “surgical optimization” approach.
This resulted in a significantly lower training cost of $5.58 million compared to the estimated $100 million for GPT-4, demonstrating that effective AI models can be developed with limited resources. DeepSeek-R1’s open-source nature allows developers worldwide to access, modify, and integrate the model freely, promoting collaboration in AI research. Its release has also influenced the broader AI industry, prompting companies to reconsider the necessity of expensive training methods.
The model’s efficiency even contributed to a major stock sell-off for Nvidia, as investors questioned the future demand for high-end AI chips. However, Nvidia’s leadership maintains that advanced computing power will still be essential for refining AI models post-training.
o3-mini
o3-mini is a compact AI model developed by OpenAI, released in January 2025. Designed to offer advanced reasoning capabilities in a more efficient package, O3 Mini serves as a precursor to the more powerful O3 model. It is accessible to all ChatGPT users, with free users having limited access and Pro subscribers enjoying unlimited usage.
o3-mini is particularly adept at tasks involving mathematics, coding, and science, providing faster responses at a lower operational cost. This release is part of OpenAI’s strategy to enhance AI accessibility and maintain competitiveness in the evolving AI landscape.
The development of o3-mini was influenced by the emergence of competitive models like DeepSeek’s R1, which demonstrated high performance with efficient resource utilization. In response, OpenAI accelerated the release of o3-mini to offer users a capable alternative that balances performance and efficiency.
