Our take
Developers and researchers seeking a free, capable large language model will find Dots3-Note Preview particularly useful. Its 512,000-token context window allows for extensive input, making it suitable for tasks like analysing lengthy research papers or complex codebases, unlike alternatives such as Claude or ChatGPT which, while also AI chatbot/assistants, are not explicitly noted for such extensive context windows in their basic offerings. The model's vision capabilities mean it can interpret image inputs, broadening its application beyond text-only models. Furthermore, its support for tool/function calling and structured JSON outputs positions it as a foundation for agent-style workflows, catering to those building more sophisticated AI applications rather than simply engaging in conversational chat. While its availability and rate limits are dependent on the OpenRouter API, its completely free access and built-in reasoning mode for difficult problems make it an option for those who prioritise functionality and cost-efficiency.
