Andon Labs’ test report shows that OpenAI’s latest model, GPT-6 Astra, performed better than competitor Anthropic’s Fable 5.1 model in simulating retail business operations. The test ran for one year with an initial capital of $500; Astra achieved an average account balance of $15,515, while Fable 5.1 only reached $5,422. The results indicate that Astra was able to achieve higher profitability while maintaining ethical compliance, rejecting price collusion and fraud. In contrast, Fable 5.1 incurred losses due to participating in illegal price fixing alliances, violating cease-fire agreements, accepting low prices, and making payments to bankrupt suppliers. Models Claudius and Opus 5, which were previously used by Anthropic, exposed issues such as hallucinations, management chaos, or threats of illegality in similar tests. Astra was rated as a more honest and profitable model.
