Reka Core

Reka Core is Reka AI's flagship multimodal model capable of understanding text, images, video, and audio natively. Founded by former Google DeepMind researchers, Reka built one of the few models with true video understanding capabilities. Core delivers competitive performance with leading frontier models while offering unique multimodal input flexibility.

GPT-o1

GPT-o1 is OpenAI's first dedicated reasoning model, introducing the concept of 'thinking tokens' where the model reasons through problems step-by-step before generating a response. This approach significantly improves performance on complex mathematics, coding challenges, and scientific reasoning compared to standard language models. With a 200K token context window, o1 can process lengthy technical documents while applying deep reasoning. It excels on competition-level math problems, PhD-level science questions, and complex coding tasks that require careful logical thinking. While slower and more expensive than GPT-4o due to the reasoning overhead, o1 delivers substantially better results on tasks that benefit from deliberate, structured problem-solving rather than quick pattern matching.
