Most-discussed: Expensive models think, cheap models implement by Duy /zuey/; Run OpenCode with local Ollama models in a sandbox by tensorsandtokens; Share work memory across Claude Code, Codex and Pi by /u/danilofs.

Quick start (from Expensive models think, cheap models implement by Duy /zuey/):

Use expensive models for brainstorming, analysis, architecture, design and planning.
If they need to inspect a repo, connect them via CloudHarness MCP.
Throw the plan to Pi/OMP and let cheap models implement.

All 5 OpenCode agent setup & config use cases

Expensive models think, cheap models implement
GPT models plan via CloudHarness MCP; Pi/OMP implement with DeepSeek V4.1 Flash/GLM-5.3 via OpenCode Go for ~$10/mo.
1. Use expensive models for brainstorming, analysis, architecture, design and planning.
2. If they need to inspect a repo, connect them via CloudHarness MCP.
3. Throw the plan to Pi/OMP and let cheap models implement.

Run OpenCode with local Ollama models in a sandbox
On a 48GB MacBook: Docker sbx sandbox + OpenCode + Ollama with Qwen 3.8 27B for multi-hour runs.
1. Install Docker Sandbox: brew trust docker/tap && brew install docker/tap/sbx.
2. Install OpenCode: brew install anomalyco/tap/opencode. Install the Ollama app.
3. Pull a workhorse model (e.g. ollama pull qwen3.8:27b-mxfp8, ~32GB) for long runs.

Share work memory across Claude Code, Codex and Pi
Nimrod reads each agent’s local session files into one SQLite log, injects a project brief at session start and answers queries over MCP.
1. Read each agent’s own session store (JSONL or SQLite on disk) without writing to it.
2. Extract what was asked, files touched, commands run and how it ended into one local SQLite database; no model writes to the log.
3. Inject a short project brief at the start of each session.

Move your default coding agent to OpenCode via OpenRouter
DeepSeek V4.1 Flash passed every run of his two-task test at about two cents a task (self-reported, "a field report and not a ranking").
1. Point OpenCode at OpenRouter (gateway optional): The author routes everything through LiteLLM with names like cloud-coder, fallbacks and per-app budgets.
2. Run your own two-task bake-off: One easy and one hard task with hidden tests; two runs per model; grade pass/fail, time and cost.
3. Pick the cheapest model that passes: For him: DeepSeek V4.1 Flash as default.

Run OpenCode on DeepSeek or GLM models
OpenCode on DeepSeek V4.1 Flash or GLM-5.3 instead of a native seat
1. Install OpenCode: curl installer, Homebrew or npm.
2. Connect a provider with /connect: Keys are stored in ~/.local/share/opencode/auth.json.
3. Pick a model with /models; start on Flash: Confirm the model ID in /models rather than guessing it.
