This seems like a sheets implementation of something like ChainForge (<a href="https://github.com/ianarawjo/ChainForge">https://github.com/ianarawjo/ChainForge</a>).<p>It's curious that Anthropic is entering the LLMOps tooling space ---this definitely comes as a surprise to me, as both OpenAI and HuggingFace seem to avoid building prompt engineering tooling themselves. Is this a business strategy of Anthropic's? An experiment? Regardless, it's very cool to see a company like them throw their hat into the LLMOps space beyond being a model provider. Interested to see what comes next.
