@blingdivinity In fact, I earlier tested this on GPT-5.4: injecting Juice via the developer prompt still produced statistically significantly fewer reasoning tokens than the effort parameter—though that only speaks for 5.4.
@blingdivinity Yes, it may well think longer; in fact, simply asking the model to "think carefully" also yields a statistically significant increase in thinking time. But that doesn't prove it matches the Juice in the real system prompt, unless you can back it up with data.
@StevanBoljevic@Lentils80 It's just a unitless value in the system prompt. OpenAI likely used a juice-aware approach in training to make Juice softly correlated with the actual reasoning effort.
@soniox_ai Great! I like soniox STT models and it's really great that you frequently updating it to make it better (v5). In fact I do believe you are making the best STT models in the world (keep it up!) but not getting enough attention.
