1. What Is Ollama

Ollama runs open-weight models locally (Llama, Qwen, DeepSeek, Mistral). No cloud, no API key, no bill. The default local CLI.

2. Install

brew install ollama        # macOS
curl -fsSL https://ollama.com/install.sh | sh   # Linux
ollama pull llama3.1
ollama run qwen2.5

3. Who Reaches It

• Privacy users
• Cost-sensitive devs
• Offline workers
• Hobbyists

Reach: fastest-growing local AI tool.

4. Real Use-Cases

1. Private chat — no data leaves
2. Code — local assistant
3. RAG — docs offline
4. Embeddings — vector store
5. Agents — Hermes backend
6. Translate — offline
7. Summarize — local docs
8. Prototype — before cloud

5. CPI / Cost

$0. No tokens, no API. Only electricity + hardware.
Compare: cloud 4o = $0.025/task, Ollama = $0.

6. vs Cloud CLIs

• OpenAI/Claude: better quality
• Ollama: free + private
• Hybrid: Ollama default, cloud for hard

7. Local Integration

Hermes + Ollama = my $0 stack. Phone (Termux) runs 7B models.

8. Cost Control

• Already $0
• Use small models (7B) for speed

9. Risks

• Hardware limit
• Less multimodal

10. My Stack

Hermes + Ollama (Qwen/DeepSeek) + cloud for research.
