Qwen is good for reasoning/feedback/creative work. I use it a lot when reviewing documentation, prose and some code, it's the one I like the most.
But when it comes to researching information is consistently among the worst performers in my comparisons.
Generally the order is Opus 4.1 > Perplexity > Gemini Pro >> GPT 5 >> Qwen.
I got Perplexity Pro one year for free, what makes Opus 4.1 search so good? Is it worth switching?
I don't know whether I can give you a conclusive answer, due to how query-dependent the results are and the lack of determinism.
I really like perplexity and if you get it free it's hard to justify spending 100$/month.
I understand, I thought maybe there was a couple of cases you stumbled upon that Opus 4.1 was better at, which made you rank it higher than Perplexity!
Yes this happened.
Few recent examples:
- find me public companies listed in Poland that have the best z-index of dividend yield, payout ratio and earnings growth
- list the most important psychological tendencies and biases that crew resource management tries to address
By research you mean web search/deep research or only use knowledge embedded in llm? I use ChatGPT most of time, didn't find Claude work better for me, maybe I should switch if there is a big gap in performance.
Deep research, I don't trust LLMs with anything really.
