Open source fine-tuning & reinforcment learning (RL) for gpt-oss, Llama 4, DeepSeek-R1 and Qwen3 LLMs! Beginner friendly.
Resumen
Resumen Principal
Unsloth se presenta como una solución vanguardista para la optimización del entrenamiento y el finetuning de Grandes Modelos de Lenguaje (LLMs), prometiendo una aceleración sin precedentes y una eficiencia mejorada. Su principal propuesta de valor es la capacidad de entrenar modelos personalizados en tan solo 24 horas, en contraste con los 30 días que comúnmente requieren las metodologías tradicionales. Esta extraordinaria velocidad se consigue a través de un enfoque técnico avanzado: la derivación manual de los pasos matemáticos más intensivos computacionalmente y la escritura de kernels de GPU especializados, lo que permite una mejora sustancial en el rendimiento sin necesidad de actualizar el hardware existente. La plataforma destaca por ser **hasta 30 veces más rápida que Flash Attention 2 (FA2
