GLM-5.2 has been identified as the most cost-effective AI model currently available, offering approximately 95% of the intelligence of Opus 4.8 at a significantly lower cost. Priced at $5.80 per million tokens, GLM-5.2 is about 80% cheaper than Claude and provides a competitive edge in terms of cost-to-intelligence ratio. This model is the first open-source solution to achieve frontier-level performance at a fraction of the price of its competitors. In comparison, GPT-5.5 costs around $9.70 per million tokens with 92% intelligence, while Opus 4.8 and Fable 5 are priced at $23 and $30 respectively, offering 98% and 100% intelligence. The strategic use of GLM-5.2 in a "barbell" approach, where it handles the bulk of tasks, is recommended for maximizing efficiency and cost savings.
