Which one, for what

Lemonade B

Good 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 64
  • Schema & documentation, 70 against 47

Watch for

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

llama.cpp C

Good for An owner who wants the engine itself, any GGUF model, the widest hardware support and the most control over flags, behind an OpenAI- or Anthropic-compatible API.

Ahead on

  • Security & auth, 52 against 36
  • Maintenance & community, 81 against 76

Also in its favour

  • No key needed to call it

Watch for

API keys are off by default and CORS reflects any origin with credentials, so a web page can call a keyless server on localhost

Verdicts

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.

llama.cpp

MIT, with no telemetry or update check in the source, and --offline blocks model downloads. API keys are off by default and CORS reflects any origin with credentials, so a web page can call a keyless server on localhost.

Before you call either

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

llama.cpp

  1. Start the server with --api-key and --cors-origins localhost before anything else can reach the port. Both are off by default
  2. Pass n_predict or max_tokens. Generation is unbounded by default
  3. Send response_fields to /completion to drop the fields you don't read
  4. Wait and retry on a 503 unavailable_error. The model is still loading
  5. Read the server README of the build you run. Behaviour changes between nightly builds without a changelog entry

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.
