ARE OTHER LLMs VIABLE – WORTH THE SPEND?
Other than OpenAI and Grok, every other LLM is utterly incompetent for our purposes – embarrassingly so. Occasionally we find perplexity useful for research.

Is there any reason we should continue to pay for our accounts with Anthropic, Gemini, et all?

They brag about context window size for example but cannot tolerate large documents, hallucinate terribly, and err constantly.

I realize what we do is harder for LLMs than math and code, but that doesn’t prevent OpenAI from handling it.
