Qflash is a standalone, single-binary gateway that exposes Qwen3.8 model spaces on Hugging Face through a standard OpenAI-compatible API. It automatically detects and supports multiple upstream protocols:
- gradio `/respond` endpoints (such as `https://microhero-qwen3-8-27b-uncensored-chat.hf.space`, running live on ZeroGPU)
- direct OpenAI `/v1/chat/completions` endpoints (such as `https://wanyamaelis-qwen3-8-27b.hf.space` and `https://apathy-exe-qwen3-8-flash-next.hf.space`, running `llama-server` on CPU)
- direct OpenAI `/v1/chat/completions` endpoints (such as `https://wanyamaelis-qwen3-8-27b.hf.space` and `https://apathy-exe-qwen3-8-flash-next.hf.space`, running persistent `llama-server` instances on CPU with zero quota limits)
- gradio `/respond` endpoints (supported for custom spaces such as `https://microhero-qwen3-8-27b-uncensored-chat.hf.space`)
- gradio `/chat_response` endpoints (such as `https://halvo78-qwen3-8-flash-next-playground.hf.space`)
It translates standard `/v1/chat/completions` and `/v1/models` requests and Server-Sent Events (SSE) stream protocols into upstream formats, allowing any standard OpenAI-compatible client, agent, or IDE to interface with Qwen3.8 models without modification.

## Features
- openai-compatible chat completions (streaming and non-streaming)
- automatic upstream failover across ZeroGPU and non-ZeroGPU endpoints
- automatic upstream failover across configured non-ZeroGPU endpoints
- smart endpoint cooldown (5 minutes on quota exhaustion, 30 seconds on network errors)
- automatic upstream endpoint detection (`respond`, `openai`, `chat_response`)
- deep reasoning extraction with thinking trace passthrough (`<think>` tags and blockquotes mapped to `reasoning_content`)

### Auto-failover and ZeroGPU quota handling
### Auto-failover and quota handling
Spaces running on ZeroGPU provide free A10G compute, but anonymous requests share a small pool per IP address. When ZeroGPU runs limit is reached, upstream returns a quota error (`429` or `ZeroGPU runs limit`).
Default endpoints run on persistent non-ZeroGPU hardware with no daily runs limit. When custom ZeroGPU spaces are configured, anonymous requests share a small pool per IP address. When runs limit is reached, upstream returns a quota error (`429` or `ZeroGPU runs limit`).
Qflash handles this seamlessly:
Qflash handles upstream reliability seamlessly:
- with auto-failover enabled (default), when a ZeroGPU space hits its runs limit, it is placed on a 5-minute cooldown and the gateway automatically fails over to the next configured endpoint (e.g. `wanyamaelis-qwen3-8-27b`, which runs on CPU with zero quota limits)
- transient network errors trigger a shorter 30-second cooldown before retrying
- you can also provide a free Hugging Face personal access token (`https://huggingface.co/settings/tokens`) via the `HF_TOKEN` environment variable, the `-hf-token` CLI flag, or the `Authorization: Bearer hf_...` header to authenticate ZeroGPU requests directly
- with auto-failover enabled (default), when an endpoint encounters an error or timeout, it is placed on cooldown and the gateway automatically fails over to the next configured endpoint
- transient network errors trigger a 30-second cooldown, while quota limits trigger a 5-minute cooldown
- optional ZeroGPU or private spaces can be authenticated using a Hugging Face personal access token (`https://huggingface.co/settings/tokens`) via the `HF_TOKEN` environment variable, the `-hf-token` CLI flag, or the `Authorization: Bearer hf_...` header
