Five cases. One operating standard.
The OpenAI study, High Stakes Multi-Homing (Pro Users), examined how complex, real-world work moves across ChatGPT and Claude: where each product is strong, where it struggles, and how the workflow changes between the two.
S01 through S04 replicate the same task and starting prompt independently in ChatGPT and Claude, across retirement planning, federal tax, local demand generation, and brand evaluation. The matched conditions make every comparison inspectable and reveal where the products converge, diverge, or require further verification.
S05 brings the complete SDA method together in the MGM ARIA Rewards Optimizer, carrying the work from structured research and modeling through reconciliation and validation to a working decision tool.
The stakes in each case are real: a retirement runway, a tax year, a local business's growth, a brand's identity, and a family trip. People have to live with these decisions; the method has to hold up beyond the first answer.
Evidence before adjectives.
The operating rule is direct: no model is the sole validator of its own output. Disagreement between models is treated as signal, not dismissed as noise.
SparkData Analytics builds governance and verification infrastructure around that rule. The recordings are the argument: the standard made visible before anyone is asked to trust it.
A creative system, heard through its decisions.
