OpenCode
OpenCode is a terminal-based AI programming assistant built with the Go language and designed to run in command-line environments. It integrates large language model capabilities to support code generation, completion, explanation, and question-answering for programming-related tasks, with the goal of improving coding efficiency within terminal workflows. Its lightweight architecture makes it suitable for rapid deployment and use in local or server environments.
Core Facts
Ollama是一款开源的本地大模型运行框架，支持在个人电脑上一键部署各种开源大语言模型
OpenCode supports MCP (Model Context Protocol) server configuration.
Unsloth's OpenAI-compatible API has enabled gpt-6-astra (GPT-6 Astra) by default for Codex login, supporting inference intensity control ranging from Low to Max.
Timeline (last 90 days)
Self-hosting is a common prerequisite for the adoption of AI tools in regulated industries (finance, healthcare, government).
For AI coding assistants, self-hosting usually means the entire chain of sending code snippets to the model as context is fully controllable: you can connect to a local model to achieve zero code leakage, or perform auditing and desensitization behind a private gateway.
As a terminal-first tool, OpenCode 2.0 has optimized the interaction layer, reducing the friction of switching back and forth between the command line and the AI.
OpenCode 2.0 is a structural upgrade rather than a simple feature iteration, with the core changes concentrated in three directions: stronger Agent capabilities, model and configuration flexibility, and terminal interaction experience.
The benefits of model-agnostic design include: controllable cost (use a small model for simple tasks, switch to a large model for complex tasks), avoiding vendor lock-in (smooth migration when a vendor raises prices or discontinues service), and meeting compliance requirements (sensitive code can go only through local inference).
The cost of model-agnostic design is that different models vary in tool calling, instruction following and context window, and the actual results need to be verified by switching one by one.
When there is no global ~/.config/opencode/AGENTS.md, OpenCode loads ~/.claude/CLAUDE.md as global rules.
According to LogRocket's October tool rankings, Cursor's share of Ramp spend fell from 41% to 26%, while Claude Code and OpenCode rose.
Hermes IDE was developed by the article's author and can run command-line agents such as Claude Code, Codex, Copilot and OpenCode side by side, each running in its own terminal and worktree with its own login credentials.
Plan mode is suitable for aligning ideas first when requirements are unclear, while build mode is suitable for directly generating code; for complex projects, planning first and then building can reduce rework.

75%VerifiedThe advantages of local open-source models over APIs include elimination of API call fees, the privacy advantage of keeping code and data on the local machine, and the controllability of being freely fine-tunable and deployable
75%VerifiedHermes Agent, OpenCode, and Claude Code all adopt the Agent Skills standard, and Skills can be used interchangeably across them.
75%VerifiedDeepSeek Harness supports adding workspaces locally, and its overall form is similar to mainstream Agent tools such as Claude Code and OpenCode.
70%VerifiedFor most developers, open weights are more practical than closed-source APIs, because they enable local deployment, fine-tuning, keeping data on-premises, customizable system prompts, and more controllable latency.
