Hi everyone! I've been diving into using LLMs for internal Q&A lately, especially for our sales team's sensitive playbooks and customer call transcripts. Data privacy is a huge concern for us.
I'm currently testing Kimi against running local models (like Llama 3.1) through Ollama on a company server. The local setup feels more secure on paper, but Kimi's long context and accuracy are so tempting for our large docs.
Has anyone run a similar comparison? I'm really torn between the convenience & power of Kimi and the peace of mind from keeping everything local. Would love to hear about your experiences, especially with lead scoring models or customer email analysis! 😊
I'm a platform engineer at a 300-person fintech; our stack is mostly AWS with Datadog for observability, and we've been prototyping local LLMs for secure internal automation while also evaluating cloud services like Kimi for less-sensitive use cases.
My comparison based on our pilot:
1. **Data Privacy Boundary:** Local/Ollama wins completely. Your documents never leave your network, which for customer call transcripts is non-negotiable in regulated industries. Kimi, while possibly having good policies, is still a third-party API call.
2. **Long-Context Accuracy:** Kimi's 200k+ context is real and usable. Our local Llama 3.1 8B via Ollama starts to reliably lose coherence on documents past 12k tokens, even with a well-tuned `num_ctx`. For analyzing a single, massive sales playbook, Kimi is superior.
3. **Real Cost:** Local setup is a fixed capex. We run it on a single `g5.2xlarge` instance (~$1-1.5/hr). Kimi's pricing isn't fully public yet, but for similar volume we were quoted on an enterprise plan starting at ~$25/user/month for our team size, plus API overages.
4. **Operational Burden:** Kimi is a managed API - zero ops. Our local Ollama setup required about 3 engineer-days to get stable, with ongoing updates for model versions and occasional GPU memory issues (~5% of our weekly support tickets are related to it). That's a real TCO hit.
My pick: For customer email analysis where data can be anonymized, Kimi's long context is the better tool. For raw call transcripts and sensitive lead scoring, you must go local. To make a clean call, tell us your team's engineer-to-sales ratio and whether your documents can be stripped of PII before querying.
