# LlmBench AI Provider Support and WebViews

> Understand LlmBench account-backed WebViews, native provider transports, gateway adapters, and the current compatibility boundary.

LlmBench combines account-backed provider WebViews with a native chat/compare layer. Provider-specific behavior stays behind bounded adapters instead of leaking across the UI.

## Account-backed WebViews

The current Android client includes WebView entries for ChatGPT, Claude, Gemini, DeepSeek, Kimi, Mistral Vibe, Qwen, Microsoft Copilot, Z.ai, Grok, Character.AI, Venice, and Meta AI.

<Warning>
  "Integrated" does not guarantee that every provider permits fresh embedded sign-in. Authentication remains between the provider page and that provider, and LlmBench does not scrape passwords, cookies, OAuth tokens, or page contents.
</Warning>

| Provider | Status | Uploads | Activity tracking | Notes |
| --- | --- | --- | --- | --- |
| ChatGPT | Full | Yes | Generating + unread | Persistent provider-scoped session |
| Claude | Full | Yes | Generating + unread | Persistent provider-scoped session |
| Gemini Chat | Partial | Yes | Generating + unread | Fresh Google OAuth may be blocked in embedded user-agents |
| DeepSeek | Full | Yes | Generating + unread | Persistent session |
| Kimi | Full | Yes | Generating + unread | Persistent session |
| Mistral Vibe | Full | Yes | Generating + unread | Provider-scoped activity probe |
| Qwen | Partial | Provider-documented; embedded flow unverified | Not yet | Embedded sign-in/upload verification pending |
| Microsoft Copilot | Partial | Provider-documented; embedded flow unverified | Not yet | Provider-owned auth hosts are bounded in-WebView |
| Z.ai | Partial | Page-driven; embedded flow unverified | Not yet | Provider-owned auth hosts are bounded in-WebView |
| Grok | Partial | Provider-documented; embedded flow unverified | Not yet | Activity probe still needs verification |
| Character.AI | Partial | Provider-documented image attachments; embedded flow unverified | Not yet | Sign-in/upload verification pending |
| Venice | Partial | Provider-documented; embedded flow unverified | Not yet | Sign-in/upload verification pending |
| Meta AI | Partial | Not verified | Not yet | Provider-owned Meta login surface |

## Native and free-provider layer

The native chat layer is already implemented, not merely planned:

- **Gemini** through `generateContent` REST with streaming support.
- **OpenAI** through the Responses API with `store=false` and bounded visible-text replay.
- **Claude** through its native API transport.
- **OpenRouter Free** through the shared OpenAI-compatible gateway adapter.
- **AIHubMix Free** through the same gateway boundary.

The two gateway aggregators stay outside the default All Models comparison so the same underlying model is not routed twice.

## Provider tweaks and diagnostics

Provider tweaks live in a small, auditable in-app registry. Scripts are static, scoped to matching provider hosts, and applied after page load; remote userscript code is never fetched.
Diagnostics expose only privacy-safe integration metadata such as provider host, WebView package/version, capability counts, activity-tracking support, and file-picker events. They do not collect page text, full URLs, form values, file names, cookies, or authentication tokens.

<Note>
  Compatibility for newer providers is intentionally marked partial until embedded sign-in, uploads, and provider-specific generation tracking are verified in the Android WebView.
</Note>

## Gemini and embedded Google sign-in

Gemini Chat is integrated, but Google may reject OAuth flows from embedded user-agents. That is a provider policy boundary, not something LlmBench attempts to bypass.
