Free Frontier Models Are Proliferating — and GLM-5.2 Claims to Beat GPT-5.5 on SWE-Bench

Multiple threads documented 12+ frontier-class models now accessible for free through platforms like zenmux and Nvidia endpoints, with GLM-5.2 reportedly outperforming GPT-5.5 on coding benchmarks.

A growing number of frontier-class models are now accessible at zero cost through third-party platforms. As @FareaNFts catalogued, at least 12 models — including GLM-5.2, recent Mistral releases, and DeepSeek variants — are available through free API endpoints from services like zenmux and Nvidia's developer programs. GLM-5.2 is the headline grabber: it reportedly outperforms GPT-5.5 on SWE-Bench, the widely used software engineering benchmark.
