Community member questions if open-source LLMs are now 'good enough' for 95% of business needs, weighing cost-benefit of further quality gains
English summary
A Reddit post by u/AdDizzy8160 asks whether open-source LLMs have reached a practical threshold where they can reliably meet 95% of organizational requirements, and whether the extra cost of proprietary models for the remaining 5% is justified. The user breaks down potential sources of added value—better answer quality, more reliable automated workflows, reduced risk of criticism, higher productivity, and general risk management—and questions each from a cost-benefit angle. The post frames the decision primarily as a financial and internal positioning argument rather than a pure technical race, inviting others to share perspectives that could strengthen the case for open-source adoption.
