Proposal: AnyLLM as a provider preset — one OpenAI-compatible endpoint for 24+ Chinese & international models

Hi NextChat team

NextChat remains the go-to self-hosted chat UI, and its custom-endpoint support is a big reason why — a huge share of the community runs NextChat with BASE_URL pointed at DeepSeek, SiliconFlow, or an OpenAI-compatible gateway (there are dozens of tutorials for exactly this pattern).

That said, the custom-endpoint path today is a hand-typed three-field exercise:

Endpoint / BASE_URL — users must know the exact endpoint format (and on older frontends, protocol sniffing mis-detects non-OpenAI providers, which is why guides tell people to also set OPENAI_BASE_URL) API Key — a separate key per upstream Custom model names — model IDs typed by hand, comma-separated, no validation, and stale the moment the upstream ships a new model I'd like to help fix all three at once by contributing an AnyLLM provider preset. AnyLLM is a unified OpenAI-compatible API gateway — one API key, one Base URL, 24+ leading models from both sides of the firewall:

Chinese: DeepSeek V4 Flash/Pro, Qwen3.7-Plus, GLM-5.2/5.1 (up to 2M context), Kimi K2.5/K2.6, MiniMax M3/M2.7, Xiaomi MiMo v2.5 Pro/v2 Pro International: GPT-5.6 Luna, GPT-5.4 Mini/Nano, Gemini 3.5 Flash (multimodal) Pass-through pricing, no markup; international cards and crypto accepted — so NextChat users outside China can finally reach DeepSeek / Qwen / GLM / Kimi without a Chinese phone number or Alipay, and don't need separate OpenAI / Google accounts either.

What I'd contribute (all low-maintenance by design):

A built-in provider preset (same pattern as the existing provider dropdown): default Base URL pre-filled, so users only paste an API key — no more hand-typed endpoints or protocol-sniffing workarounds A maintained default model list for the preset, kept in sync as the gateway adds models (I maintain it; it's just a comma-separated string update) A docs/README recipe for the zero-code path that works today: set the endpoint to the AnyLLM URL, paste the key, done — useful even if the preset isn't merged Optional enhancement (happy to discuss separately): the custom-model field could optionally fetch GET /v1/models when a custom endpoint is configured, turning the hand-typed list into a picker. The gateway side returns a standard OpenAI model list, so this would work for any OpenAI-compatible upstream, not just AnyLLM — it directly addresses the most common misconfiguration reports ("model name 404 after typo").

Before opening a PR, a few questions:

Would a provider preset be a welcome addition, given the project's current maintenance cadence? I'll keep the diff minimal — a preset entry plus a docs section, no core logic changes. Model list handling — for existing setups, would you prefer the preset's model list shipped in code, or fetched at runtime from /v1/models (cached, with the hand-typed field as fallback)? Any branding/contribution guidelines for provider presets I should follow — anything beyond CONTRIBUTING.md? I'll provide free API credits for any maintainer who wants to test the integration, and maintain the preset long-term.

Thanks for keeping NextChat alive — it's still the first thing I recommend to anyone who wants a private ChatGPT.
