Ollama Cloud vs your own server: what changes
Ollama Cloud and a self-hosted Ollama share one CLI and one API. See exactly which settings change, and what leaves your machine on each path.
Which AI models can you self-host?
Pick a model by the RAM you actually have. Sizing arithmetic for 4 GB, 16 GB and 64 GB VPS plans, honest CPU token rates, and the hidden cost of context.
KV cache vs prompt cache explained
The KV cache is RAM your server pays for on every request. Prompt caching is a bill someone else discounts. Only one can break a model load.
Ollama context length: setting num_ctx
Ollama truncates long prompts at a small default context window. Set num_ctx per request or server wide, and size the KV cache RAM before you raise it.
Keep an Ollama model loaded in memory
Ollama unloads your model after 5 minutes idle, so the next request pays the full load time again. Set keep_alive so it sticks, even after a reboot.
AI Agent vs LLM vs AI Assistant
An LLM is weights that need RAM. An assistant adds a chat surface. An agent adds tools and a loop, and it holds credentials, so it needs a box that stays on.
Self-host Langfuse to trace your AI agents
Run Langfuse on your own VPS: the real resource floor, pinned image tags, TLS, ClickHouse retention before it fills the disk, and backups that work.
Ollama vs vLLM: which LLM server to run
Ollama is a convenience layer for one user, on CPU if needed. vLLM is a throughput engine for GPUs. Pick by workload, with the real commands for both.
Can you self-host Claude? The honest answer
Claude's weights are not public, so no server of yours can run it. Here is what you can self-host instead: open models, a gateway, and Claude Code.
Host Ollama on a VPS: self-host an LLM safely
A 7B model wants 8 GB of RAM and gives 4 to 10 tokens per second on CPU. Host one on a VPS and call it at 127.0.0.1:11434/v1, with port 11434 kept closed.
Build your own OpenClaw-style AI agent
OpenClaw is a personal AI agent that runs commands on your own server. Here is how one is built, piece by piece, and why hardening comes first.
Build your own AI agent on a VPS
An AI agent is a loop around a language model that can use tools. Learn the concepts behind building one on your own VPS: the loop, tools, MCP, memory.
Build an AI agent with Claude on a VPS
Use Claude as the brain and your VPS as the body. How the Messages API, tool use, and MCP fit together to build an AI agent you run yourself.
