Seeking Affordable GPT-4 + Search Alternatives to Perplexity.ai (lemm.ee)

I'm looking for more cost-effective alternatives to Perplexity.ai that offer GPT-4 integration along with search capabilities for factual assistance, ideally around $5/month instead of the $20/month subscription fee for Perplexity.ai. I've come across Nuggt (https://github.com/Nuggt-dev/Nuggt), but it seems to rely solely on a local model without search functionality. I've also found Phind.com, a developer-focused search engine that uses GPT-4 to answer technical questions with code examples and detailed explanations. While it may not be as good as Perplexity.ai, it offers more free uses. Are there any other options that combine GPT-4 and search features at a lower price point?

It's doable on your own, you can use embeddings for prefiltering (searching) what you want and then provide the top results as a context for GPT. Or if you have existing search, you can skip the embeddings and just feed GPT the top results.

I don't think local models have enough context yet. I don't know how perplexity manages to use so many websites as references. As soon as there is a model like WizardCoder that has a 10k context or higher, I'll give this a try.

I didn't mean local models, but using some kind of fulltext search engine to preselect data to feed GPT-4.

Maybe try kagi's FastGPT. It seems to be free to use, which is delightfully cost-effective.

This is a frontend to FastGPT API, which is pay-per-request. It probably uses Claude for synthesis, rather than GPT4. The search source is no doubt Kagi's own search, a hybrid private index+Bing+Google that I use all day long as a much better Google.

I pay for Kagi, but I checked every which way and FastGPT never seemed to want money or a Kagi account.
