1. Only do searches that result in easily verifiable results from non-AI sources.
2. Always perform the search in multiple products (Gemini 1.5 Deep Research, Gemini 2.0 Pro, ChatGPT o3-mini-high, Claude 3.7 w/ extended thinking, Perplexity)
With these two rules I have found the current round of LLMs useful for "researchy" queries. Collecting the results across tools and then throwing out the 65-75% slop results in genuinely useful information that would have taken me much longer to find.
Now the above could be seen as a harsh critique of these tools, as in the kiddie pool is great as long as you're wearing full hazmat gear, but I still derive regular and increasing value from them.
