Push URL host knowledge from `Endpoint` (route layer) up to `model.baseURL`
(provider helper layer). The route just composes a path onto whatever
host the model already carries.
Endpoint:
- `Endpoint<Body>` shrinks to `{ path }`. No more `default`, `baseURL`,
or `required` fallback fields.
- `Endpoint.path(value)` replaces the old `Endpoint.baseURL({...})` factory.
- `Endpoint.render()` is now sync — `${model.baseURL}${path}` plus query
params. No fallback chain, no Effect wrapper.
ModelRef:
- `ModelRef.baseURL: Schema.String` (was optional). Every materialized
model carries a host.
- `RouteModelInput.baseURL?: string` stays optional so route defaults
can supply a canonical URL; routes without a default tighten it.
Provider helpers:
- Each protocol exports a `DEFAULT_BASE_URL` constant and bakes it into
`route.defaults.baseURL`. Provider helpers don't need to set baseURL.
- Azure uses a new `AtLeastOne<T>` helper from `auth-options.ts` to
require either `resourceName` or `baseURL` at the type level.
- Bedrock provider computes baseURL from `region` at construction time.
- OpenAI-compatible profiles now have required (not optional) `baseURL`
in their type — all 9 already supplied one.
- The `defaultBaseURL: string | false` knob on protocol endpoint
factories is gone.
Effects:
- Forgetting baseURL is now caught at compile time (TS) or model
construction time (modelWithDefaults runtime check), not request time.
- `Endpoint.render` no longer needs Effect wrapping in the transport
hot path.

Installation Directory
The install script respects the following priority order for the installation path:
$OPENCODE_INSTALL_DIR- Custom installation directory$XDG_BIN_DIR- XDG Base Directory Specification compliant path$HOME/bin- Standard user binary directory (if it exists or can be created)$HOME/.opencode/bin- Default fallback
# Examples

XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
Agents
OpenCode includes two built-in agents you can switch between with the Tab key.
- build - Default, full-access agent for development work
- plan - Read-only agent for analysis and code exploration
- Denies file edits by default
- Asks permission before running bash commands
- Ideal for exploring unfamiliar codebases or planning changes
Also included is a general subagent for complex searches and multistep tasks.
This is used internally and can be invoked using @general in messages.

Building on OpenCode
If you are working on a project that's related to OpenCode and is using "opencode" as part of its name, for example "opencode-dashboard" or "opencode-mobile", please add a note to your README to clarify that it is not built by the OpenCode team and is not affiliated with us in any way.
FAQ
How is this different from Claude Code?
It's very similar to Claude Code in terms of capability. Here are the key differences:
- 100% open source
- Not coupled to any provider. Although we recommend the models we provide through OpenCode Zen, OpenCode can be used with Claude, OpenAI, Google, or even local models. As models evolve, the gaps between them will close and pricing will drop, so being provider-agnostic is important.
- Built-in opt-in LSP support
- A focus on TUI. OpenCode is built by neovim users and the creators of terminal.shop; we are going to push the limits of what's possible in the terminal.
- A client/server architecture. This, for example, can allow OpenCode to run on your computer while you drive it remotely from a mobile app, meaning that the TUI frontend is just one of the possible clients.
