+## About
+
+Atomic Agent is an open-source, local-first AI agent that runs on your computer. It plans multi-step tasks and executes them with real tools: shell, files, browser automation, skills, and MCP servers. All agent state, memory, and configuration live on your machine in `~/.atomic-agent`.
+
+Atomic Agent can run open models fully locally through a built-in llama.cpp backend, or connect to cloud models. AI/ML API is a **native built-in provider**: one API key gives the agent access to 500+ models, including GPT, Claude, Gemini, Qwen, and Grok families, with no endpoint configuration.
+
+Atomic Agent is MIT-licensed and available for macOS, Linux, and Windows.
+
+{% hint style="success" %}
+**No native Anthropic or Google provider exists in Atomic Agent.** AI/ML API is the built-in way to use Claude and Gemini models with it.
+{% endhint %}
+
+### What you get
+
+* A terminal agent (CLI + TUI) that plans and executes multi-step tasks
+* Tool use out of the box: shell, file operations, browser automation, skills, MCP servers
+* Local-first state: config, memory, and sessions stored in `~/.atomic-agent`
+* Mix of local and cloud models in one app (for example, local embeddings + cloud chat)
+* Live model catalog: the provider fetches the current AI/ML API model list at setup time
+* Telegram connector and an OpenAI-compatible local HTTP server
+* MIT license, installs without an account
+
+***
+
+## Quick Install
+
+One command, no account or key required:
+
+```sh
+# macOS / Linux
+curl -fsSL https://atomicagent.io/install | sh
+```
+
+```powershell
+# Windows
+irm https://atomicagent.io/install.ps1 | iex
+```
+
+***
+
+## Configuration
+
+You will need an AIMLAPI key from your [account dashboard](https://aimlapi.com/app/keys).
+
+### Option 1: Built-in provider wizard (recommended)
+
+Atomic Agent ships with a native AI/ML API provider, so there is nothing to configure by hand.
+
+1. Run `atomic-agent tui`.
+2. Type `/model` to open the LLM Local/Cloud panel.
+3. Select **AI/ML API (aimlapi.com — 500+ models, OpenAI-compatible)**.
+4. Paste your API key when prompted.
+5. Pick a chat model. The list is fetched live from the AI/ML API, so new models appear as soon as they are released.
+
+The wizard stores the key as `AIMLAPI_API_KEY` in `~/.atomic-agent/.env` and writes the provider entry to `~/.atomic-agent/config.json`.
+
+### Option 2: Manual configuration
+
+Add the provider to the `llm` block of `~/.atomic-agent/config.json`:
+
+```json
+{
+  "llm": {
+    "activeTextProvider": "aimlapi",
+    "activeEmbeddingProvider": "local-llama",
+    "toolTransport": "auto",
+    "providers": [
+      {
+        "id": "aimlapi",
+        "kind": "aimlapi",
+        "defaultChatModel": "openai/gpt-5.5-2026-04-23"
+      }
+    ]
+  }
+}
+```
+
+Then put your key in `~/.atomic-agent/.env`:
+
+```sh
+AIMLAPI_API_KEY=your_key_here
+```
+
+The base URL (`https://api.aimlapi.com`) is built into the provider; you do not need to set it.
+
+{% hint style="info" %}
+If you prefer the generic `"kind": "openai-compatible"` provider instead, set `"baseUrl": "https://api.aimlapi.com"` **without** the `/v1` suffix. Atomic Agent appends `/v1/chat/completions` itself, and a doubled path returns 404. That provider kind reads its key from `OPENAI_COMPAT_API_KEY`.
+{% endhint %}
+
+***
+
+## Model Selection
+
+* Default chat model for the AI/ML API provider: `openai/gpt-5.5-2026-04-23`.
+* Any model ID from the [AI/ML API catalog](https://aimlapi.com/models) works, for example `anthropic/claude-sonnet-4-5` or `alibaba/qwen3.8-max-preview`. The configured model ID is sent to the API as-is, so you are not limited to the bundled list.
+* Embedding models from the AI/ML API catalog can be selected too, or embeddings can stay on the local llama-server daemon.
+* For cloud models, Atomic Agent uses native function calling, so tool use works out of the box.
+
+***
+
+## Verification
+
+Start a session:
+
+```sh
+atomic-agent tui
+```
+
+Ask for something that requires a tool call, for example: "list the files in this folder and summarize them". If the model responds and tools execute, the integration is working.
+
+***
+
+## Use Cases
+
+* **Frontier models inside a local agent.** Keep the agent runtime, tools, and files on your machine while using top cloud models for reasoning.
+* **Claude and Gemini in Atomic Agent.** These model families are only reachable through an aggregator; AI/ML API is the supported path.
+* **One key, many models.** Switch between model families without separate accounts and billing per provider.
+* **Mixed setups.** Run embeddings locally and chat in the cloud, or the other way around.
+
+***
+
+## Troubleshooting
+
+<details>
+
+<summary>401 / authentication errors</summary>
+
+Check that `AIMLAPI_API_KEY` is present in `~/.atomic-agent/.env` and has no extra whitespace. Re-entering the key via the `/model` wizard rewrites it correctly.
+
+</details>
+
+<details>
+
+<summary>404 on chat requests (manual openai-compatible setup)</summary>
+
+Remove the `/v1` suffix from `baseUrl`. The agent appends `/v1/chat/completions` itself.
+
+</details>
+
+<details>
+
+<summary>Model not found</summary>
+
+Verify the exact model ID against the [AI/ML API models list](https://aimlapi.com/models). The ID is passed to the API verbatim.
+
+</details>
+
+<details>
+
+<summary>Switching provider or model later</summary>
+
+Open `/model` in the TUI at any time to change the provider or the chat model. No restart is required.
