Open LLMs in 2023: BLOOM, OPT, GLM-130B and GPT-NeoX-20B Accelerate Open-Source AI

AI Impact Summary

2023 marks a clear pivot toward open LLMs, with major families like BLOOM, OPT, GLM-130B and GPT-NeoX-20B shaping the ecosystem and Hugging Face anchoring community access. Open weights and transparent data/training details enable reproducibility, benchmarking transparency, and broader scrutiny of biases, while lowering the barrier to experimentation. For technical teams, this expands viable architectures and tooling but shifts compute, licensing, and governance burdens toward open resources that require self-hosting or managed inference strategies.
