Choose an AI integration¶

JSAT can connect to a native coding client, use Ollama directly, or let Ollama launch a coding client with a local or cloud model. These are separate execution paths. Choose the tab that matches the process you intend to run.

Native Codex owns the conversation and model. JSAT supplies MCP tools and the $jsat dispatcher.

jsat index .
jsat connect codex
jsat start codex --via native

Complete native Codex guide

Native Claude Code owns the conversation and model. JSAT supplies MCP tools, /jsat, and /jsat-help.

jsat index .
jsat connect claude --global
jsat start claude --via native

Complete native Claude guide

A PATH-installed OpenCode owns the model and provider. This route does not invoke Ollama's launcher.

jsat index .
jsat connect opencode
jsat start opencode --via native

Complete native OpenCode guide

JSAT talks directly to a model served by Ollama. No coding-client harness is involved.

Complete direct Ollama guide

Ollama launches Claude Code and supplies one selected local or cloud model to that process.

jsat index .
jsat connect ollama tool=claude
jsat ollama --tool claude

Complete Ollama-launched Claude guide

Ollama launches OpenCode and supplies one selected local or cloud model. A standalone OpenCode installation is not required.

jsat index .
jsat connect ollama tool=opencode
jsat ollama --tool opencode

Complete Ollama-launched OpenCode guide

Ollama launches Codex and supplies one selected local or cloud model.

jsat index .
jsat connect ollama tool=codex
jsat ollama --tool codex

The distinction that prevents duplicate pulls¶

Route	Conversation host	Who selects the model?	Needs `ollama pull`?
Native Claude/Codex/OpenCode	Native client	That client/account	No
Direct Ollama	JSAT shell	`jsat ai use ollama --model ...`	Local models only
Client through Ollama	Claude/Codex/OpenCode	Ollama selector or `--model`	Local models only
Client through Ollama Cloud	Claude/Codex/OpenCode	Ollama selector or cloud model name	No; use `ollama signin`

jsat ai use ollama configures the AI provider used by JSAT's own LLM-backed tools. jsat ollama --tool TOOL configures only the launched client process. One does not silently replace the other.

Manage all coding clients¶

With no target, lifecycle commands apply to Claude, Codex, and OpenCode:

jsat start
jsat ps
jsat restart
jsat stop
jsat resume

Interactive clients open in separate terminals. To keep routes isolated, name one client and one route, for example jsat start claude --via ollama --model qwen2.5:0.5b.
