As a current OpenAI subscriber (just the regular $20/mo plan), I'm happy to not spend the effort switching as long as they stay within a few negligible percent of the State of the Art. I tried DeepSeek, it's fine, had some downtime, whatever, I'll just stick with 4o. Claude is also fine, not noticeably better to the point where I care to switch. OAI has my chat history which is worth something I suppose - maybe a wee…

4o isn’t really comparable to deepseek r1. Use o3-mini-high or o1 if you wanna stay near the state of the art.

I've had a coding project where I actually preferred 4o outputs to DeepSeek R1, though it was a bit of a niche use case (long script to parse DOM output of web pages).

Also they just updated 4o recently, it's even better now. o3-mini-high is solid as well, I try it when 4o fails.

One issue I have with most models is that when they're re-writing my long scripts, they tend to forget to keep a few lines or variables here or there. Makes for some really frustrating debugging. o1 has actually been pretty decent here so far. I'm definitely a bit of a power user, I really try to push the models to do as much as possible regarding long software contexts.

The best practical benchmark I found is asking LLMs to research or speak on my field of expertise.

Yeah...and it didn't cite me :)

Yeah, that's a data point as well. I found a model that was good with citations by asking it to recall what I published articles on.

That's the third product to use "Deep Research" in its name. The first was Gemini Deep Research: https://blog.google/products/gemini/google-gemini-deep-resea... - December 11th 2024 Then ChatGPT Deep Research: https://openai.com/index/introducing-deep-research/ - February 2nd 2025 Now Perplexity Deep Research: https://www.perplexity.ai/hub/blog/introducing-perplexity-de... - February 14th 2025.

I own DeepCQ.com since early 2023 - Which could do "deepseek" for financial research. Maybe I just throw this on the pile, too.

You are a bit behind. All the "deep research" tools, and paid AI search tools in general, combine LLMs with search. When I do research on you.com it routinely searches a 100 sites. Even Google searches get Gemini'd now. I had to chuckle because your very link provides a demonstration.

> You are a bit behind. Quite the opposite. I'm familiar enough with these systems to know that asking the question "List the college majors of all Fortune 100 CEOs" is not going to get you a correct answer, Gemini and you.com included. I am happy to be proven wrong. :)

But the whole point of these “deep research” models is to.. you know.. do research.

LLMs by themselves have not been good at this, but the whole point is to find a way to make them good.

I'm unimpressed. I gave it specifications for a recommender system that I am building and asked for recommendations and it just smooshed together some stuff, but didn't really think about it or try to create a resonable solution. I had claude.ai review it against the conversation we had.. I think the review is accurate. ---- This feels like it was generated by looking at common recommendation system papers/blogs and synthesizing their language, rather than thinking through the actual problems and solutions like we did.

In about 2 weeks since OpenAI launched their $200/mo version of Deep Research, it has already been open sourced within 24 hours (Hugging Face) and now being offered for free by Perplexity. The pace of disruption is mind boggling and makes you wonder if OpenAI has any moats left.

OpenAI has the normies. The vast majority of people I know (some very smart technical people) havent used anything other than ChatGPT's GUI.

>I like their API as well as a developer, but it seems like other competitors are mostly copying that too, so again not a huge reason to stick with em.

You can also use tools like litellm and openrouter to abstract away choice of API

It failed my first test which concerned Upside magazine. All of these deep research versions have failed to immediately surface the most famous and controversial article from that magazine, "The Pussification of Silicon Valley." When hinted, Perplexity did a fantastic job of correcting itself, the others struggled terribly. I shouldn't have to hint though, as that requires domain knowledge that the asker of a query m…

Every week we get a new AI that according to the AI-goodness-benchmarks is 20% better than the old AI, yet the utility of these latest SOTA models is only marginally higher than the first ChatGPT version released to the public a few years back.

These things have the reasoning skills of a toddler, yet we keep fine-tuning their writing style to be more and more authoritative - this one is only missing the font and color scheme, other than that the output formatted exactly like a research paper.
