Milestones in Modern LLMs

What are some major milestones in modern LLMs?
Large language models (LLMs) have evolved rapidly over the past several years. Early models like BERT popularized transformer architectures in 2018, while GPT-2 and GPT-3 demonstrated increasingly fluent text generation from 2019 to 2020. The release of ChatGPT in late 2022 introduced conversational interfaces to a mainstream audience and kickstarted widespread adoption.
Open-source projects such as LLaMA and the rise of specialized instruction tuning accelerated progress in 2023 and 2024. These efforts paved the way for even larger models with multimodal abilities and longer context windows. Platforms like Benched.ai's milestone tracker chronicle how each new generation pushes the boundaries of reasoning, creativity, and real-world usability.
Today, researchers continue to iterate on techniques like retrieval augmentation and efficient fine-tuning. Milestones increasingly revolve around practical considerations—scalable deployment, alignment with human intent, and responsible use—rather than pure model size. As LLMs integrate into products and workflows, their milestones reflect both technical breakthroughs and their impact on everyday applications.
