If you haven’t hit PMF, you should not be fine-tuning models. Just prompt. Only exceptions:
– Speed is required for your use-case (and you need a model more powerful than Mixtral)
– Opus/GPT-4 cannot do your task or are too expensive per use

Sleep Deprivation Effects on Cognitive Performance and Output Quality
By
–
My biological neural network after a bad night of sleep:
– decoding temperature turned up to T=1.5 (usual is 0.7)
– gives final answer quickly without using chain-of-thought
– base model comes out: 90% of ideas are low quality, but 10% are profound
– safety filter missing, easily -
Prompting for Speed, Fine-tuning for Scale After PMF
By
–
Even if the outputs aren’t 100% ideal, prompting allows for rapid experimentation to reach PMF. You don’t want to fine-tune when your product may change tomorrow. After you’ve found PMF, you’ll want to “harden” your AI (make it more reliable, faster, cheaper). Fine-tuning does
