| ``` When to use fine-tuning:
|
| Fine-tuning GPT models can make them better for specific
| applications, but it requires a careful investment of time
| and effort. We recommend first attempting to get good results
| with prompt engineering, prompt chaining (breaking complex
| tasks into multiple prompts), and function calling, with the
| key reasons being: * There are many tasks for which our
| models may initially appear to not perform well at, but with
| better prompting we can achieve much better results and
| potentially not need to be fine-tune * Iterating over prompts
| and other tactics has a much faster feedback loop than
| iterating with fine-tuning, which requires creating datasets
| and running training jobs * In cases where fine-tuning is
| still necessary, initial prompt engineering work is not
| wasted - we typically see best results when using a good
| prompt in the fine-tuning data (or combining prompt chaining
| / tool use with fine-tuning) ```

| Current AI detectors are pure garbage. Anybody paying for one

| decisions is making a grave error.
|
| It's a real shame that some schools are using AI detectors to

| being AI-generated that are _clearly_ written by hand.
|
| All it takes is half an hour of playing with ChatGPT and asking

| with some decent prompting, you can get it to write in other
| styles, but let's be honest, anybody using ChatGPT to do their

| look like ChatGPT.
