Which one, for what

HyperQwen C

Best for An operator with one 24 GB NVIDIA card who wants Qwen3.8-27B behind an OpenAI-compatible endpoint for a coding or tool-calling agent, with long context.

Ahead on

  • Security & auth, 41 against 36

Also in its favour

  • No key needed to call it

Watch for

Serves Qwen3.8-27B and checkpoints derived from it only. Other models are on the roadmap

Lemonade B

Best for An owner with AMD hardware (Ryzen AI NPUs, Radeon or Strix Halo) who wants one local server for chat, speech and images that existing OpenAI, Anthropic or Ollama clients can call, and for MCP clients that want local models as tools.

Ahead on

  • Reliability, 75 against 59
  • Schema & documentation, 70 against 56
  • Agent ergonomics, 70 against 65
  • Maintenance & community, 76 against 68
  • Transparency & trust, 65 against 55

Watch for

No authentication by default. With no key set, every route answers, including /internal/* shutdown and configuration

Verdicts

HyperQwen

HyperQwen packages a patched vLLM 0.32.0 and requantised Qwen3.8-27B weights into one container with tool calling preset and a loopback bind when no key is set. It runs one model family, its speed figures come from one RTX 3090, and it has no versioned releases, changelog or security policy.

Lemonade

Apache 2.0, with weekly releases, installers for Windows, macOS and five Linux routes, and a six-tool MCP endpoint whose descriptions steer a caller away from accidental multi-gigabyte downloads. Authentication is off by default, the repository has no security policy, and the docs tell WebSocket clients to pass the key in the URL.

Before you call either

HyperQwen

  1. Call http://127.0.0.1:18020/v1 with model qwen3.8-27b and the VLLM_API_KEY value, or any string if no key was set
  2. Poll /health before the first request. A first start downloads and prepares the model and compiles kernels, which can take over 30 minutes
  3. Declare the context window your setup uses (65,536 by default, 131,072 for CTX=long, 245,760 for CTX=huge) so the client doesn't truncate
  4. Ask the owner to set VLLM_API_KEY before setting BIND=0.0.0.0, and to front the port with a proxy that allowlists routes
  5. Treat the README's tokens-per-second figures as the project's measurements on one RTX 3090 at 250 W

Lemonade

  1. Call lemonade_list_models (or GET /v1/models) before naming a model. A wrong name with allow_download: true can start a multi-gigabyte download
  2. Send Authorization: Bearer <key> when the operator has set LEMONADE_API_KEY. /internal/* needs the admin key when one is set
  3. Use POST /v1/chat/completions for streamed tokens, embeddings and speech. The MCP endpoint ignores stream and has no embeddings or text-to-speech tool
  4. Pass output_dir to lemonade_generate_image and lemonade_omni to get file paths in place of inline base64. Writes stay inside the MCP media sandbox
  5. Read GET /v1/docs on the running server for the reference that matches its version. Weekly releases change behaviour

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
