The artificial intelligence (AI) landscape is evolving rapidly, but this growth is accompanied by significant challenges. High costs of developing and deploying large-scale AI models and the difficulty of achieving reliable reasoning capabilities are central issues. Models like OpenAI’s GPT-4 and Anthropic’s Claude have pushed the boundaries of AI, but their resource-intensive architectures often make them inaccessible to many organizations. Additionally, addressing long-context understanding and balancing computational efficiency with accuracy remain unresolved challenges. These barriers highlight the need for solutions that are both cost-effective and accessible without sacrificing performance. To address these challenges, ByteDance has introduced Doubao-1.5-pro, an AI model
