OpenAI o1 and o3 Reasoning Models Quiz

Answers and explanations appear as you take the quiz.

1. What does OpenAI’s o-series documentation say the models use before returning a final answer?
   • Internal reasoning tokens that are not necessarily exposed as a full user-visible transcript
   • A guaranteed step-by-step explanation shown to every user
   • A separate web search for every response
   • No extra computation beyond a standard model
2. What does OpenAI say is part of the o1 series training approach?
   • Only retrieval from a web index
   • Reinforcement learning to perform complex reasoning
   • Only next-token pretraining with no post-training
   • Only human-written chain-of-thought imitation
3. What does inference-time compute scaling mean for reasoning models?
   • Each additional reasoning token guarantees a better answer
   • The model retrains its weights after each question
   • More reasoning computation may improve some tasks, with added cost and latency
   • Extra computation removes the need to evaluate model versions
4. How should a reported benchmark score for an OpenAI reasoning model be interpreted?
   • As a guarantee of performance on every user task
   • As a result that applies to all future o-series versions
   • As independent of the benchmark harness
   • As tied to the named model version and evaluation protocol
5. Why might internal reasoning tokens affect API cost even when users do not see them?
   • They count toward output usage and context limits
   • They are removed from all billing and token accounting
   • They are stored only in the user’s browser
   • They replace all visible answer tokens
6. What is a typical downside of o1/o3-style reasoning models?
   • They cannot answer any questions
   • Higher cost and slower responses on hard queries
   • They never make mistakes
   • They only work in English
7. What does a reasoning-effort setting influence in an API request?
   • The model’s training data after deployment
   • Whether the model can access every third-party tool
   • The reasoning budget allocated to the request
   • The benchmark score reported for earlier versions
8. How should developers check which OpenAI reasoning model is available and its current API behavior?
   • Assume every o-series model has identical endpoints
   • Use an old benchmark article as an API specification
   • Infer availability from the model family name alone
   • Consult the current official model and reasoning documentation for that version
