Inflection AI unveils Inflection 2.5, a friendlier AI assistant that rivals GPT-4 performance on 60% less compute for training

Inflection AI, an AI startup founded by tech luminaries Mustafa Suleyman, co-founder of Deepmind, and Reid Hoffman, co-founder of LinkedIn, has just dropped its latest heavyweight in the world of AI: Inflection-2.5.

Hot on the heels of its predecessor, Inflection 2, released back in November 2023, this new launch comes at a time of fierce competition in the AI landscape. Anthropic’s unveiling of Claude 3, boasting its speed and robustness, adds to the narrative of innovation in the industry. The trio of AI tools, Claude 3 Opus, Sonnet, and Haiku, sets the stage for a showdown of the Titans.

Inflection-2.5 isn’t just another model; it’s the powerhouse behind Pi, the startup’s user-friendly AI assistant. With claims of being as potent as OpenAI’s GPT-4 but requiring a mere 40% of the computational resources for training, Inflection is making bold strides toward efficiency and effectiveness in AI communication. What sets it apart is its emphasis on empathy and helpfulness, marking a departure from the cold, calculating nature of traditional models.


Drawing from the lessons of its predecessor, Inflection-2.5 enters the ring ready to spar with heavyweights like GPT-4 and Google’s Gemini. While not quite surpassing GPT-4, it certainly holds its own, particularly in domains like mathematics, coding, and multi-task language understanding (MMLU).

The real kicker? Inflection-2.5 achieves this near-GPT performance with significantly less computational power. This efficiency is a testament to the company’s dedication to optimizing the AI training process, setting a new benchmark for the industry.

Currently, Inflection-2.5 is the powerhouse behind Pi, the company’s alternative to ChatGPT, known for its empathetic, witty, and engaging demeanor. Available across multiple platforms, including iOS, Android, web, and desktop, Pi has already facilitated over 4 billion messages, with an average conversation time of 33 minutes. It’s a testament to the growing demand for personalized AI experiences.

In our June 2023 coverage, we delved into Inflection’s meteoric rise after securing a massive $1.3 billion in funding from heavyweights like Microsoft and Nvidia, signaling the unabated momentum of the AI boom. Shortly before this funding milestone, Inflection made waves with the launch of its inaugural AI chatbot, Pi, echoing the functionality of OpenAI’s ChatGPT.

Pi, as described by the company, harnesses generative AI technology akin to ChatGPT, facilitating engaging user interactions through dialogue, question-and-answer sessions, and feedback loops. This announcement coincided with Reid Hoffman’s departure from the OpenAI Board of Directors, a strategic move to sidestep potential conflicts of interest.

Founded in 2022 by Hoffman alongside Mustafa Suleyman and former DeepMind researcher Karén Simonyan, Inflection AI swiftly emerged as a frontrunner in the realm of generative AI, akin to its counterpart, OpenAI.

With Suleyman’s track record, including the sale of DeepMind to Google in 2014, Inflection AI represents a new chapter in his entrepreneurial journey. Teaming up with Hoffman, the duo is poised to reshape the landscape of AI-driven consumer products.

As Inflection continues to evolve, one thing is clear: the AI revolution is showing no signs of slowing down, and with pioneers like Inflection AI leading the charge, the possibilities are endless.
