AI Provider Setup and Notifications

Supported AI Providers

Nimbalyst is meant to work with your coding agents. The following are currently supported:

• Claude Code

• Codex (SDK)

• Codex over ACP (Alpha)

• OpenCode (Alpha)

• GitHub Copilot (Alpha)

Alpha providers are toggled on individually from their own settings panels. See Alpha Features.

You can configure Nimbalyst to also access AI Models directly.

OpenAI Codex

You must separately download the Codex CLI (or app). Either authenticate there in the CodexCLI or provide Nimbalyst with an API token for OpenAI..

On the Global Settings screen (Select Nimbalyst -> Settings), enable Codex and configure its integration with Nimbalyst.

Codex transcripts have feature parity with Claude in Nimbalyst:

• Inline edit cards — Codex file_change tool calls render as red/green edit cards in the transcript, matching how Claude's Edit tool already renders.

• Slash command autocomplete — Codex slash commands surface in the same unified / picker as Claude Code commands.

• Cross-agent skills and commands — Skills and commands written for one agent run in the other, so workflow discovery is unified across providers.

• Reasoning blocks — Codex reasoning items map into transcript thinking blocks.

Claude Code

On the Global Settings screen (Select Nimbalyst -> Settings), enable Claude Code and configure its integration with Nimbalyst.

New users default to Opus 4.6 with 1M context window. Existing Opus users are automatically migrated to this configuration.

If you already have a coding agent installed and running on your desktop, we will use it through its SDK. If you do not have Claude Code CLI, we will install it for you automatically.

You must either enter your API Key in the Settings in Nimbalyst or authenticate to Anthropic in the CLI.

Claude Enterprise SSO is supported — if your organization uses Claude Enterprise, you can authenticate via SSO.

Effort Level

Claude Code supports an effort level slider that maps to the Claude Code CLI's /effort setting. Higher levels let the model spend more thinking budget on a turn at the cost of more tokens.

Pick from five levels:

• low

• medium

• high

• xhigh

• max

The Effort Level selector is in the agent's session controls. The choice is forwarded to Claude Code via the CLAUDE_CODE_EFFORT_LEVEL environment variable.

OpenAI Codex over ACP (Alpha)

An alternative way to run Codex inside Nimbalyst. Instead of using the Codex SDK, this provider speaks the Agent Client Protocol over stdio, which gives Nimbalyst native pre/post file-edit hooks. The practical benefit is more accurate diff baselines (especially for newly created files) and deterministic per-session attribution for apply_patch edits. Your MCP servers are forwarded to the agent automatically.

Enable it under Settings → Agent Providers by selecting the Codex (ACP) provider. It appears in the model picker alongside the SDK Codex provider.

OpenCode (Alpha)

OpenCode is an open-source coding agent with multi-model support — it works with Claude, OpenAI, Gemini, and local models through a unified interface.

Select OpenCode under Settings → Agent Providers:

1. Install the OpenCode CLI (use the Install OpenCode CLI button or follow the OpenCode docs).

2. Toggle Enable OpenCode on.

3. Optionally provide an API key — model selection and provider configuration are managed through OpenCode's own settings, so no additional configuration is required here.

GitHub Copilot (Alpha)

GitHub Copilot is supported as a coding agent via the ACP (Agent Communication Protocol) server mode. It uses your existing Copilot CLI login for authentication.

Select GitHub Copilot under Settings → Agent Providers:

1. Install the Copilot CLI (npm install -g @github/copilot, or use the Install Copilot CLI button).

2. Toggle Enable GitHub Copilot on.

3. Authenticate by running copilot and using the /login command. Model selection is managed by Copilot — no additional API key is required.

Integrate other AI Models with Nimbalyst (optional)

• Nimbalyst can integrate with Anthropic, OpenAI or LM Studio for Local Models

• You must provide your API key to integrate with each

• As these are not coding agents, only some features will be supported

• For LM Studio, you must have this installed locally

• (Return to this screen from Nimbalyst -> Settings if you want to change this config later)

Notification that AI response is complete

Under Nimbalyst -> Settings. Click on Notifications

By default:

• You are notified when you AI session completes

• And if you are not in the window, it will pop up a notification when the session completes. Clicking on that notification takes you to the window where the session was running.

You can turn one or both off
