Are Language Models a Commodity?
Language models have shifted from luxury assets to near‑free utilities as token‑processing costs plunge and open‑weight models like Llama and Mistral rival commercial offerings. Free‑access tools such as Ollama let users run powerful models locally, eliminating subscription fees and API limits. While basic text generation is now commoditized, specialized, fine‑tuned models for niche domains retain premium pricing. The article concludes that LLMs are largely a commodity, but reliability, privacy, and domain‑specific adaptation keep a segment of the market differentiated.
