On Thursday, American AI startup Inflection AI officially released a new generation of large language model Inflection-2.5.

According to reports, Inflection-2.5 will combine powerful LLM technology and Inflection’s unique “empathy fine-tuning” feature, integrating the characteristics of high emotional intelligence and high IQ. It can obtain factual information through the Internet, and its performance is comparable to leading large-scale models such as GPT-4 and Gemini.

Inflection-2.5 is now available to all Pi users for free on PC, iOS and Android apps. After a simple test by Heart of the Machine, we found that there is still a certain gap compared with GPT-4, but it is still worth a try. Interested users can experience it themselves.

It is worth noting that Inflection -2.5 achieves performance close to GPT-4, while the training process only uses 40% of the computing power of GPT-4.

Inflection AI points out that a new generation of large-scale models has made significant progress in areas such as intelligent coding and mathematics. These advances will translate into concrete improvements to key industry benchmarks, ensuring Pi remains at the forefront of technology. In addition, Pi also integrates world-class real-time web search capabilities to ensure that users have access to high-quality breaking news and the latest information.

Inflection-2.5 vs GPT-4

The FLOP used in Inflection-1 training is about 4% of GPT-4, in various In "IQ-oriented" tasks, its average performance is about 72% of the GPT-4 level. Now, Inflection-2.5 achieves an average performance of over 94% of GPT-4, despite using only 40% of GPT-4’s FLOPs for training. As shown in the figure below, the performance of Inflection-2.5 has achieved significant improvements across the board, with the greatest improvements in STEM domain knowledge.

The results of Inflection-2.5 on two different STEM exams - the Hungarian Mathematics Examination and the Physics Graduate Record Examination (GRE) - are as follows:

As shown in the table below, the study also evaluated Inflection-2.5 on the MMLU benchmark and GPQA Diamond benchmark. The MMLU benchmark covers 57 disciplines in STEM, humanities, social sciences, and more, effectively testing an LLM’s comprehensive knowledge capabilities, while the GPQA Diamond benchmark is an extremely difficult expert-level benchmark.

On the BIG-Bench-Hard benchmark, Inflection-2.5 improves performance by more than 10% than Inflection-1 and is comparable to GPT-4 Comparable. The BIG-Bench-Hard benchmark mainly covers problems that are difficult to solve with large language models.

The study was also evaluated on the MT-Bench benchmark. However, the research team realized that the benchmark had a large portion (nearly 25%) of sample examples in the Reasoning, Mathematics, and Coding categories with incorrect reference solutions or flawed premises. Therefore, the study corrected these examples and performed the evaluation experiments again, and the results are shown in the following table:

Evaluation on GSM8k and MATH benchmarks The results show that Inflection-2.5 is a significant improvement over Inflection-1 in terms of math and coding capabilities:

To further test the coding of Inflection-2.5 Ability, this study conducted evaluation experiments on two coding benchmarks, MBPP and HumanEval, and the results are shown in the following table:

The research team evaluated Inflection-2.5 on HellaSwag and ARC-C, as well as various models on common sense and scientific benchmarks. Judging from the results below, Inflection-2.5 achieves strong performance on these benchmarks.

Additionally, all of the above evaluations were done using models that now support Pi. However, it is also important to note that the user experience may vary slightly due to network retrieval (the above benchmark does not use network retrieval), the structure of the few-shot prompts, and other production aspects.

In general, Inflection-2.5 maintains Pi’s “heart-centered” features and extremely high security standards, becoming a more comprehensive and useful model.

In recent times, the technology competition for large language models has entered a fierce stage. Among many technology companies, Mistral AI (Mistral Large ), Anthropic (Claude 3) stand out, and the new technology proposed achieves capabilities close to GPT-4 and Gemini Ultra. Inflection-2.5, which appeared yesterday, seems to be joining the first echelon.

As a star startup in Silicon Valley, Inflection AI has a long history. It was established in 2022. The three co-founders are Mustafa Suleyman, the original co-founder of DeepMind, and the co-founder of Linkedln. Reid Hoffman, and former DeepMind chief scientist Karen Simonyan.

In June last year, Inflection AI announced that it had received US$1.3 billion in financing from Microsoft, Nvidia, Reid Hoffman, Bill Gates, and former Google CEO Eric Schmidt led the investment. Currently, Inflection AI has become the fourth largest generative AI startup in the world.

AI Paints A New Picture For The Future Of Art And DesignAI Paints A New Picture For The Future Of Art And DesignApr 26, 2025 am 11:10 AM

AI: The Future of Art and Design Artificial intelligence (AI) is changing the field of art and design in unprecedented ways, and its impact is no longer limited to amateurs, but more profoundly affecting professionals. Artwork and design schemes generated by AI are rapidly replacing traditional material images and designers in many transactional design activities such as advertising, social media image generation and web design. However, professional artists and designers also find the practical value of AI. They use AI as an auxiliary tool to explore new aesthetic possibilities, blend different styles, and create novel visual effects. AI helps artists and designers automate repetitive tasks, propose different design elements and provide creative input. AI supports style transfer, which is to apply a style of image

The Prototype: American Scientists Are Looking For Jobs AbroadThe Prototype: American Scientists Are Looking For Jobs AbroadApr 26, 2025 am 11:07 AM

The development of scientific research and technology in the United States may face challenges, perhaps due to budget cuts. According to Nature, the number of American scientists applying for overseas jobs increased by 32% from January to March 2025 compared with the same period in 2024. A previous poll showed that 75% of the researchers surveyed were considering searching for jobs in Europe and Canada. Hundreds of NIH and NSF grants have been terminated in the past few months, with NIH’s new grants down by about $2.3 billion this year, a drop of nearly one-third. The leaked budget proposal shows that the Trump administration is considering sharply cutting budgets for scientific institutions, with a possible reduction of up to 50%. The turmoil in the field of basic research has also affected one of the major advantages of the United States: attracting overseas talents. 35

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
