1. Confirm exactly what the AI is analyzing
A plausible answer can still be about the wrong game. Match the teams, league, date, start time and time zone to an official schedule. Then check whether the recommendation concerns a full-game moneyline, a first-half spread or a player prop. Those are different markets.
Record the sportsbook, selection, line and odds. A recommendation at one price does not establish value at a different price. If these details are absent, request them before interpreting the conclusion.
Our current odds input guide gives you a consistent way to supply that snapshot.
2. Follow the sources, not the tone
Open the cited injury report or statistical source yourself. Confirm that it exists, concerns the correct player or team, and was updated before the analysis. An old report can be genuine but no longer useful.
OpenAI explains that ChatGPT can give incorrect facts or fabricated citations and can sound confident while doing so. Search tools can help retrieve current information, but an answer still needs verification. Do not assume a tool was used because the answer says “today.”
- Fact: a dated report identifies a player's listed status.
- Assumption: the player will receive a particular workload if active.
- Unknown: the role has not been confirmed in the supplied sources.
Ask the assistant to maintain those three categories. If sources disagree, compare update times and primary reports; do not average conflicting facts into a new invented claim.
3. Separate calculations from predictions
A displayed percentage is not necessarily a tested probability. “High confidence” may just be the assistant's phrasing. Ask where the probability came from, which data it used and how the underlying model was evaluated.
A simulation claim needs more than a sentence saying “I ran 1,000 games.” Ask for the executed code, inputs, assumptions and output. OpenAI's data-analysis tools can run code, but that capability does not mean every answer ran a simulation. Without execution evidence, treat it as a proposed method, not a result.
Recheck odds conversions and payouts with the sports betting calculator. For model estimates, read AI Model Edges as model-versus-market comparisons, not proof that a wager will win.
If assessing a prediction service over time, ask for the complete sample, losses, stakes and prices—not selected screenshots. Do not infer that a particular site's record is complete or independently audited without evidence.
A reusable verification prompt
Audit this analysis using only the attached data: [analysis and dated sources]. Confirm the event, market, odds and source timestamps. Separate sourced facts from assumptions. Flag unsupported injuries, probabilities and simulation claims. Recalculate any arithmetic. List missing inputs and contradictions. If the evidence is insufficient, say so; do not replace missing facts with guesses.
This prompt asks for an audit, not a second confident pick. Compare the returned checklist with the actual sources before using it.
4. Allow “not enough information”
Pause when the odds are stale, the player status is unresolved, the event is wrong or the probability has no defensible basis. Asking an AI to always choose a side encourages it to fill gaps rather than acknowledge them.
Check the dates on published predictions and keep any planned exposure within your bankroll limits. Better research cannot eliminate the chance of losing, and chasing losses is not a verification strategy.
