Hello, OpenAI team.
I’m a Brazilian attorney and long-time ChatGPT user since its earliest public release — currently a Plus subscriber. Over time, I’ve developed a rigorous and high-frequency usage pattern focused on testing the model’s limits in logical consistency, behavior under ambiguity, and performance in irreversible decision-making scenarios.
My usage style involves:
-
Simulated environments with unpredictable behavior (e.g., bugged game systems, puzzles, edge-case logic traps);
-
Literal and source-based validation of legal, financial, technical, and medical outputs;
-
Stress-testing prompts using controlled contradictions, multi-variable logic, and emergent system behavior;
-
Treating the model as a critical reasoning engine, often applying multi-pass verification under strict accuracy constraints.
I routinely challenge the model with long-session interactions, pattern induction, and layered ambiguity to expose behavioral drift, false consistency or hallucination under pressure. I also document and reflect on cases where the model performs exceptionally well under complexity.
In one of my most demanding use cases, I leveraged the model to analyze and distill over 1,000 pages of legal and financial documentation related to lawsuits spanning more than 45 years. These cases included complex elements such as historical currency transitions in Brazil, inflationary adjustments, and outdated legal frameworks — requiring precise tracking of monetary values across decades and legal systems. The model was stress-tested in interpreting nuanced data and surfacing inconsistencies across multiple generations of financial records.
If there’s any structured or informal path for collaboration — early access testing, QA feedback, or contribution under NDA — I’d be honored to help. GPT-4o is, in my view, a historical milestone and I believe I can contribute meaningfully to its refinement.
Best regards,
