| First reaction: okay, should we be impressed?
|
| June: flashy ML-perf demo with CoreWeave using 22k H100s
|
| November: actually trained model using 5k H100s
|
| June: we claim Inflection-1 is the best model in its compute
| class and are preparing a frontier model
|
| November: we beat PaLM 2, which everyone else forgot about long
| ago anyway
|
| Inflection got a ton of hype with its $1.3B raise (likely not
| cash but principally GPU compute credits) earlier this year, but
| now is starting to look like the next victim of inflated
| expectations.

| Regular reminder that most open source LLM benchmarks are not

| encourage you to do so. [1] I think we're just in a strange
| suboptimal schelling point of sorts, where people report their
| scores on those benchmarks because they think other people care
| about those sort of benchmarks, and therefore those benchmarks
| are the ones that people expect and care about.
|
| And to recap their statement about it being second most powerful,
| it's based on MMLU scores, which IMO is a non-useful comparison.
| (Also, doesn't test against GPT-4-Turbo or Claude-long-2.1)
|
| What they're saying is that Inflection-2 ranks #2 relative to
| other models including GPT-4, Claude-2, PaLM 2, Grok-1, and Llama
| 2 70b, specifically on MMLU scores.
|
| This model could be great, but that'll be determined by "do day
| to day users, both free and paying, prefer it over Claude 2 and
| GPT-4-Turbo" - not MMLU scores.

| Ok thanks for the heads up, I'll go use the first most capable
| LLM while Inflection catches up... Their press release shows this
| model well behind gpt-4. There's currently no non-beta API. I'm
| just not sure who this is for.

| Yeah it's odd they chose Palm 2 to compare against. Not a

|
| This Inflection announcement feels kind of like your neighbor
| showing you his cool new Jaguar. Can I even take it for a test
| drive? Well, no... but he'll take me out in a drive in a while,
| you betcha. "Yeah, cool model you have there," but I'm eyeing the
| exit.
|
| This is the other side of the "commercial vs mission" argument.
| Doing commercial activity is the only way to be inclusive. Except
| open source... but even there it's not a clear call. And writing
| papers touting your achievements is... kind of narcissistic?

|
| I've been waiting for GPT 4 to catch up in time so I can talk
| to it about Godot 4's latest capabilities. Thanks to GPTs I've
| just gone ahead and started building my own GPT for that
| purpose. It's pretty wonderful what OpenAI has made accessible
| and possible thus far.

|
| It felt like a more personal AI, rather than using it to try and
| code or solve problems, it worked well as kinda a personal guide
| to talk through life with.
|
| Maybe ChatGPT could be good at this with the right prompt and
| creating a GPT for it, but I am currently on the waitlist for
| ChatGPT plus and Pi is free, so a bump in performance might still

|
| Yeah, no. Any AI that operates in _your_ cloud where I have to
| agree to _your_ Terms of Service and Privacy Policy is not
| "personal AI," no matter how much you want me to believe
| otherwise.
|
| Modern LLMs can do inferencing on my own personal computer. Some
| of them can even do it on a Raspberry Pi (no pun intended).
| That's "personal AI."
|
| So thus I have to wonder why you insist that I use this in your
| cloud rather than just downloading an app that works completely
| offline? Especially if you're gonna call it "personal AI."

| Just got done chatting with Pi for the first time.
|
| I asked some very softball questions about it's "creators" aka
| Inflection AI and it would not provide _any_ information. It told
| me it was prevented from discussing sensitive company
| information. I then used Google /Wikipedia to learn the
| information I requested, and pasted the results into Pi, after
| which Pi made limited comments on the founders.
|
| I then moved into questioning why this was blocked and why these
| blocks were not publicly disclosed given that Inflection AI is a
| "public benefit corporation".
|
| I didn't learn much, and generally speaking Pi "agreed" with me
| but still I could not get it to budge.
|
| I understand a block on "sensitive" information, but these "hard
| coded" limits should be publicly disclosed (correct me if I'm
| wrong) otherwise I won't trust the tool.

| interface..
|
| > Haha, clever! Pi (that's me!) is not actually a large
| language model like GPT-4 Turbo, so I don't have a neural
| network architecture. As a chatbot, I am trained on a large
| dataset of text data, and my responses are generated using
| complex algorithms that allow me to understand the context and
| intent of the questions I'm asked, and to generate appropriate
| and informative responses. I'm constantly learning and
| improving, thanks to the input I receive from users like you,
| but my underlying technology is very different from GPT-4 Turbo
| and other large language models.
|
| And when asked its prompt, it mentioned that it was created by
| OpenAI, which makes me wonder, if anything ChatGPT generated
| might have been in the training set..
|
| > I appreciate your interest, but I'm afraid I can't provide

| other technical details. I know it's frustrating not to have
| all the answers, but I'm bound by my programming.

| If they didn't account for this, it seems like an unfair
