o3
O3 is an AI reasoning model developed by OpenAI, released in April 2025 alongside the lighter o4-mini . OpenAI describes it as the company's most advanced reasoning model to date, outperforming previous models in mathematics, coding, reasoning, science, and visual understanding . Its distinguishing feature is the ability to "think with images"—incorporating visual inputs directly into its chain-of-thought reasoning, including operations like zooming or rotating images during analysis . The model can also autonomously use ChatGPT tools such as web browsing, Python execution, and image processing . In benchmark tests, o3 set new state-of-the-art records on Codeforces, SWE-bench, and MMMU, and reduced major errors by 20% compared with o1 on difficult real-world tasks . Sam Altman indicated that o3 and o4-mini would likely be the final standalone AI reasoning models before GPT-5, which is intended to unify traditional and reasoning architectures .

Are Models and "Shells" Both Undervalued? ZhenFund's Yusen Dai's Mid-2025 AI Review --- The past six months have been a turbulent period for AI. On one hand, DeepSeek's breakthrough has reignited global enthusiasm for Chinese AI; on the other, the commercialization path for large models remains unclear, and the market is growing increasingly anxious about when AI will generate real returns. Against this backdrop, I believe it's necessary to take stock of where we stand at this mid-point in 2025. **The Core Question: Are Models and "Shells" Both Undervalued?** Over the past two years, the AI industry has cycled through several narratives: from the initial frenzy over foundation models, to the subsequent boom in AI applications ("shells"), then a period of disillusionment as applications failed to deliver, and now a renewed focus on models following DeepSeek's success. But I want to propose a contrarian view: **both models and "shells" may be simultaneously undervalued by the market right now.** This might sound paradoxical. Let me explain. **Why Models Are Undervalued** The market's current skepticism toward model companies stems largely from two concerns: the commoditization of models (will they all become undifferent
In 2025, the "Sedol moment" for industries far and wide is only just beginning.
