AI Models Tested: Grok 4.3 Leads, Free Tiers Show Wild Variance

A recent test of ten AI models on coding tasks revealed significant performance disparities, particularly within free tiers. Grok 4.3 emerged as the top performer with an 81.6% success rate, while Perceptron Mk1 offered exceptional value at nearly 80% for a minimal cost. Among free models, Owl Alpha stood out with a 76.7% score and no hard failures, though latency was a concern. Other models like GPT Chat Latest and Mistral Medium 3.5 showed mixed results, with the former being the most expensive and the latter experiencing timeouts. AI
