openfree/Darwin-Qwen3-4B

Darwin-Qwen3-4B is a 4 billion parameter language model developed by openfree, created using an evolutionary algorithm called 'Darwin A2AP'. This model explores a novel paradigm of AI model fusion, aiming to merge core representational structures of different model species, such as transformers and diffusion models. It is designed to create new intelligence at the intersection of domains with extreme efficiency, offering a cost-effective alternative to training new foundation models.
