OpenAI has shifted from keeping its LLMs within its infrastructure to offering GPT-OSS, a local large language model available under an open-weight license. This change reflects the ongoing democratization of AI models since the advent of ChatGPT and GPT-3. Larger cloud models continue to outperform local models, which can be competent but inconsistent. GPT-OSS raises concerns over the transparency of training data, as details remain undisclosed. Additionally, reliance on benchmarks may not accurately represent a model's true effectiveness, exemplified by the lesser-known Llama 4.
OpenAI has transitioned from proprietary models to offering GPT-OSS, a local, open-weight large language model that can be freely used and modified.
While larger models continue to deliver superior quality responses, local LLMs provide a mixed performance that can be surprisingly capable or inferior.
The move towards open-weight models like GPT-OSS raises questions about the transparency of training data, as vendors withhold specifics on model training.
Despite the advances in AI, benchmarks can sometimes misrepresent model capabilities, as evidenced by the example of Llama 4.
