Tell HN: OpenAI silently removed Study Mode from ChatGPT
Here's hoping that it will return soon, as I really liked it.

|
| My best guess is this is product strategy. A markdown file
| doesn't require maintenance, but a feature's surface area does.
| Every exposed mode is another thing to document, support, A/B
| test, and explain to new users who stumble across it. I'm
| guessing that someone decided "Study Mode isn't hitting
| retention metrics", and decided to kill it. As an autodidact, I
| loved the feature, but as a software engineer I can respect the
| decision.
|
| What I'm wondering about is whether there's a security angle to
| this as well. Assuming exposed system prompts are a jailbreak
| surface, if users can infer the prompt structure, would it make
| certain prompt injection attacks easier? I'm not well-versed in
| ML security, and I'd be curious to hear from someone who is.

| Honestly, it probably led to long conversations. The

| All of a sudden feels like it gives me boilerplate and boiler

| It's not like this on the other llms, something's up.

| people have been talking about "models of models" for

|
| Arbitration idea: if a user doesn't need high QOS of newest
| LLM, slip them a cheaper LLM, run their query at reduced
| quality. measure if they cost you fewer $s in the lower QOS. =>
| profit.
|
| For chatgpt the arbitration opportunity looks more like "we
| could allocate this amount of gpu to training or inference, we
| are losing money if we offer the highest quality infra"
|
| In addition there's other interesting economics scaling that
| can be done outside of "models of models" that are far more
| profitable. I won't go over all of them (and some of them I
| feel are quite powerful) but the laziest one is that
| subscription models count on some zombie users as a
| counterweight to highly expensive single users, and as a source
| of stable cashflow.
|
| Zombie users are ones that are paying for sub but not actively
| or barely using the service

| I mean, LLM writing has been like that from the early on. Its
| most perfect niche for writing is the LinkedIn blog post.
| coffeefirst wrote:
| That's how ChatGPT always seemed to me. One of the reasons I

|
| But I'm starting to wonder about something.
|
| I've noticed a lot of people claiming the models--all the
| models from all the big providers--are deteriorating, and then
| go on to describe the problems that skeptics picked up on
| during their first few days of usage.
|
| The models really could be getting worse. I haven't noticed
| anything but I don't know.
|
| But do you think its possible that this is more akin to a
| honeymoon period? Depending on how you use the system and a
| fair bit of luck, the problems may show up for you pretty
| early, or may take a while to become obvious.
