AI

One-click coding agents with Juspay's LLM configuration.

Currently supports OpenCode only. Skills are sourced from:

• juspay/skills — Shared AI agent skills
• anthropics/skills — frontend-design skill

OpenCode running in the terminal with Juspay's LLM (just demo to regenerate)

Prerequisites

• Nix — Install via the Nix installer. New to Nix? See the Nix First Steps tutorial.
• JUSPAY_API_KEY (Juspay employees only) — Create one at grid.ai.juspay.net/dashboard (requires VPN to create, but not to use afterwards). Not needed for non-Juspay variants.

Quick Start

nix run github:juspay/AI

This launches an interactive selector. Or run a specific variant directly:

Variant	Command	Description
opencode-juspay-oneclick	nix run github:juspay/AI#opencode-juspay-oneclick	Juspay config and skills bundled
opencode-oneclick	nix run github:juspay/AI#opencode-oneclick	Skills bundled, bring your own provider (e.g. Claude Max)
opencode-juspay-editable	nix run github:juspay/AI#opencode-juspay-editable	Creates editable Juspay config at ~/.config/opencode/opencode.json (customize)
opencode	nix run github:juspay/AI#opencode	Plain OpenCode, no config

The opencode-juspay-* variants need a JUSPAY_API_KEY. If the env var isn't set, the wrapper prompts for it interactively — handy on fresh VMs or containers. Export the var in your shell to skip the prompt on subsequent runs.

Daily Updates

This flake's flake.lock is auto-updated daily via CI, so you always get the latest OpenCode release and skills. If pinning via flake.lock in your own flake, run nix flake update AI to pull the latest.

Home Manager module (config only)

If you manage your environment with Home Manager and already have an opencode binary — from nixpkgs, or bundled with another tool — you can install just the Juspay config, without a wrapper or a second opencode, via the exposed module:

# flake inputs
juspay-ai.url = "github:juspay/AI";

# home configuration
{
  imports = [ inputs.juspay-ai.homeModules.opencode ];
  programs.opencode-juspay.enable = true;
}

This renders the same opencode.json as the packaged variants and writes it to $XDG_CONFIG_HOME/opencode/opencode.json. As with the opencode-juspay-* variants, the Juspay provider needs JUSPAY_API_KEY in the environment at runtime.

Option	Default	Description
programs.opencode-juspay.enable	false	Install the config (no binary).
programs.opencode-juspay.juspay	true	Include the Juspay litellm provider/model settings. Set false for the base settings only.
programs.opencode-juspay.settings	{}	Extra opencode settings merged on top.

The module is system-agnostic — it uses your config's pkgs, so it does not pull in this flake's nixpkgs.

Tips

Web UI

OpenCode can run as a web application in your browser:

nix run github:juspay/AI#opencode -- web

This starts a local server and opens OpenCode in your default browser. Sessions are shared between the web UI and CLI, so you can switch between them seamlessly. You can also specify a port or make it accessible on your network with --port 4096 --hostname 127.0.0.1.

See the OpenCode Web docs for more.

GLM reasoning-effort tiers

glm-latest (GLM-5.2) reasons by default. To trade thinking depth for speed, the model picker (ctrl+x m) exposes the same model at several reasoning-effort tiers — GLM-5.2 collapses low/medium into "high", so these are the only distinct levels:

Picker entry	reasoning_effort	Use it for
glm-latest	(gateway default)	the default — thinking on
glm-max	max	deepest reasoning
glm-high	high	strong reasoning, faster
glm-fast	none	no thinking, fastest replies

Picking a GLM reasoning-effort tier in OpenCode (ctrl+x m)

The tiers are defined in coding-agents/opencode/settings/juspay.nix; all target the same gateway model (glm-latest) and differ only in reasoningEffort.

Coding Agent Setup

This repo uses APM for coding agent configuration. .claude/ and .opencode/ are vendored — committed to git and kept in sync by a CI check (apm-sync workflow).

just agent                # launch agent (default: claude)
just agent::apm-vendor    # regenerate vendored .claude/ and .opencode/
just agent::update        # update apm deps to latest, then re-vendor

Override the agent with AI_AGENT:

AI_AGENT=opencode just agent
AI_AGENT='claude --dangerously-skip-permissions' just agent
