Description

Phi-4-reasoning-plus is an advanced reasoning model with 14 billion parameters, enhancing the capabilities of the original Phi-4-reasoning. It employs reinforcement learning for better inference efficiency, processing 1.5 times the number of tokens compared to its predecessor, which results in improved accuracy. Remarkably, this model performs better than both OpenAI's o1-mini and DeepSeek-R1 across various benchmarks, including challenging tasks in mathematical reasoning and advanced scientific inquiries. Notably, it even outperforms the larger DeepSeek-R1, which boasts 671 billion parameters, on the prestigious AIME 2025 assessment, a qualifier for the USA Math Olympiad. Furthermore, Phi-4-reasoning-plus is accessible on platforms like Azure AI Foundry and HuggingFace, making it easier for developers and researchers to leverage its capabilities. Its innovative design positions it as a top contender in the realm of reasoning models.

Description

Sakana Marlin serves as the Virtual Chief Strategy Officer for Ultra Deep Research, designed to allow artificial intelligence to manage research tasks while enabling human experts to concentrate on making strategic decisions. Far from being just another research assistant, this autonomous agent tackles the extensive strategic research responsibilities typically shouldered by a Chief Strategy Officer and a small research team, which would usually take weeks to complete. With the support of Sakana AI’s advanced reasoning framework, Sakana Marlin is capable of scaling inference-time computations, allowing it to engage in up to eight hours of continuous and independent reasoning. Once a research topic is established, it operates autonomously without the need for further human assistance, continuously generating hypotheses, collecting data, browsing the web, and resolving any inconsistencies it encounters. Its emphasis is not on rapid text generation; rather, it prioritizes long-term, efficient reasoning that systematically tests hypotheses and conducts web research to distill the most pertinent information from an overwhelming volume of data. Sakana Marlin transcends mere summarization, offering a nuanced and comprehensive understanding of complex subjects.
