Hi @hollow plank. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

OpenAI does offer Mixture-of-Experts (MoE)–style models, not just pure “generalist” dense models.

From the provided sources:

• The open‑weight gpt-oss-20b model is explicitly described as a Mixture‑of‑Experts (MoE) architecture. [Fine-tuning with gpt-oss]

  • The docs show how to fine‑tune it and note that you should target expert‑specific layers like mlp.experts.down_proj and mlp.experts.gate_up_proj when applying LoRA, which confirms its MoE design. [Fine-tuning with gpt-oss]

• The Korean fine‑tuning guide also treats gpt‑oss as an MoE model and discusses “MoE‑aware” LoRA configurations that include expert projection layers, again indicating a specialized MoE architecture rather than a simple generalist dense model. [Fine-tune gpt-oss Korean]

The knowledge sources you provided do not list other specific MoE models by name, nor do they compare MoE vs non‑MoE across the whole OpenAI lineup, so I can only confidently point to gpt‑oss‑20b as a documented MoE architecture model from these materials.

Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:
