playing with models at tidbit • made @LexicaArt • the best way to predict the future is to invent it
ok but when will you add back text-davinci-003

Updates to ChatGPT:
You can now choose between “Auto”, “Fast”, and “Thinking” for GPT-5. Most users will want Auto, but the additional control will be useful for some people.
Rate limits are now 3,000 messages/week with GPT-5 Thinking, and then extra capacity on GPT-5 Thinking mini after that limit. Context limit for GPT-5 Thinking is 196k tokens. We may have to update rate limits over time depending on usage.
4o is back in the model picker for all paid users by default. If we ever do deprecate it, we will give plenty of notice. Paid users also now have a “Show additional models” toggle in ChatGPT web settings which will add models like o3, 4.1, and GPT-5 Thinking mini. 4.5 is only available to Pro users—it costs a lot of GPUs.
We are working on an update to GPT-5’s personality which should feel warmer than the current personality but not as annoying (to most users) as GPT-4o. However, one learning for us from the past few days is we really just need to get to a world with more per-user customization of model personality.

here's my vibes-based gpt-5 review, mostly comparing it to opus 4.
gpt-5 is a tool. it's utilitarian intelligence. it's cheap, fast, widely available. gpt-5 is tesla model 3 of intelligence. it *should* be the model most people use, and it probably will be. it gave good responses. it behaved predictably. it will be used by many companies and people.
but... opus 4 is a much different model. it's slow, expensive, and in terms of pure utility it honestly doesn't provide much more to warrant it's higher price point. but man, opus's responses still have an indescribable feeling to them. it's the porsche 911 of LLMs. far too expensive, but otherworldly. maybe it's the better post-training. maybe it's just a bigger model. but i find myself wanting to keep using opus 4 even after trying to use gpt-5.
in terms of real world utility, I GPT-5 feels like an improvement over the baseline. just not a pareto optimal improvement. it pushes the cost-adjusted intelligence frontier. but not the non-cost-adjusted frontier. that still belongs to Opus.

i'm excited by Tidbit for one simple reason: most AI tools optimize for the median user. not Tidbit.
we're deliberately building a deeply opinionated tool for outliers - the researchers, founders, scientists, and writers pushing their fields forward.

We're getting a lot of customer demand with Tidbit, and really just need to move faster.
If you're a great engineer, open to something new, and want to ship with me + @sharifshameem for a 30-day sprint definitely DM me.
I'm free to meet irl in SF tmmro/ open to remote.

I'm looking for an engineer who believes AI interaction design is fundamentally broken. The right person:
- Gets frustrated by today's AI interfaces
- Prototypes interaction patterns that don't exist yet
- Finds themselves tweaking CSS animation between model training runs
If you've been waiting for the chance to build the AI interface you wish existed, let's talk.
