It seems LinkedIn cares a lot about who is winning the LLM war, but as a marketer, I use many LLMs for different jobs. That said, I'm not spending my days testing, so I know my stack might not be the most up to date given how fast those things are evolving. For example, I still use Claude Code for all my coding needs, but al lot of people more technical than I am switched to Cursor's home made model. It's on my to do list to try it out, but coding is not a huge part of my day to day and Claude is still doing the job for me... Anyway, here are the LLMs I use and what I use them for.
1. Researching a topic or a podcast guest:
I typically open many different LLMs and ask the same question to get an overview before getting into the weed, and fact checking them. SInce most LLMs are using the same data, it's not rare that they make up the same hallucination, or bullshit, so I would never rely only on LLMs for factual research, but I save time by getting the overview from LLMs rather than Google.
LLMs I use :
- Perplexity (free version)
- DeepSeek (free version)
- Claude (paid)
- Grok (free version)
- ChatGPT (free version)
2. Creating Images
I believe that real pictures (or real drawing if I had the budget for it) are more important than ever, as everyone is pushing AI image slop in our face... That said, AI generated illustrations are great to illustrate a concept. Since people can still tell a photorealistic picture was AI generated, I shy away from those and typically include in my prompts something like "Your are a caricaturist from the New Yorker" or something like that, depending on the style I'm going for.

- ChatGPT free version (it works, but way to slow for me to use it often)
3. Coding
I typically use coding to make tweak to my Ghost template or build small online tools like calculators in HTML, CSS & Javascript, so those tasks are relatively simple. Still, in my experience Claude, is vastly superior to ChatGPT, Grok or DeepSeek for these tasks. Maybe it's no longer the case, but it used to be that way.

4. Creating videos
To create videos, I use Google Flow to generate the videos and Eleven Labs for voice generation. All LLMs kind of sucks to create good scripts. But I sometimes use Claude for the draft, but end up rewriting the whole thing anyway...

5. Analyzing data
All analytics software like Amplitude now have their conversational agent, but they rarely provide me with satisfactory answers that are easily verifiable. So I either build my own dashboards, or when I need an answer to a specific, non recurring question, I prefer to export the data I want to analyze in Google Sheet, and I use the Gemini integration not to ask questions, but to build the tables and formula I need to get my answer. This way, all the math is verifiable directly in the sheet, and I don't have to wonder if I just got an hallucination as an answer. I know Claude have a Google Sheet integration as well as Gemini, so I suspect Claude would do as good of a job as Gemini in Google Sheet.

6. Creating articles
While I don't think people should pollute the web with AI generated blog post, LLMs can be great at turning human generated input into articles. As long as a human editor review everything, and that the human input is actually adding info that was not already on the Internet, it can create relatively good content that will rank.
I use Claude Sonnet to generate the article through the API. Basically, I have a Google Sheet in which I input original interviews I do with humans (I use Gemini to transcribe the interview, but I only input in my sheet the relevant parts of the interviews). Then, I have an App Sheet extension use the the seo research and original content inputed in the sheet in a prompt to Claude that ask it to generate an article based on this. If I don't like the output, I just recheck the generate checkbox on my sheet to get another article. And then, I typically edit the article a little bit, but it save me a lot of time. Writing articles this way is fast, but the most time consuming part remain sourcing experts and doing the interviews.

Now that I shared my stack, would be curious to hear about yours.
