   The evidence pack covers API compatibility, MCP/agents, model gallery, GPU auto-detection, and multi-user auth, but contains no mention of low-level engine tuning like mmap, mlock, memory locking, or similar model-loading parameters (LocalAI does support YAML model config with such fields per general knowledge, but no citation here confirms it).

   vLLM—none0/10

   The evidence pack documents vLLM's serving engine, API compatibility, and performance features but contains no mention of a CLI or interactive terminal chat command; only an OpenAI-compatible API server is cited, which requires a separate client, not a built-in terminal chat session. Missing for 10: any documentation of a 'vllm chat' or similar interactive terminal command, and community confirmation of using it directly from the terminal.

   Docs explicitly describe `local-ai chat` as a terminal-based agent that reads files and runs commands behind an approval gate, confirming an interactive CLI chat session. missing for 10: independent/hands-on confirmation of the chat UX, example transcripts, or details on session persistence/history in the terminal.

   vLLM—none0/10

   vLLM is an inference server/engine; the evidence describes HuggingFace model integration and API serving, but there is no CLI for searching, downloading, or managing models (that role belongs to Hugging Face Hub CLI, not vLLM itself). No evidence of any 'vllm model search/download/list' command or similar tooling.

   CLI commands like `local-ai models list` and `local-ai run huggingface://...` demonstrate searching/downloading models from the CLI, plus gallery-based install and model aliasing for management.

   weight 1 · round drawn
   vLLM—none0/10

   The evidence pack describes vLLM's general features (PagedAttention, quantization, hardware support) but contains no citation showing CLI flags for GPU offload or context-length configuration when loading a model. Missing for 10: documentation of specific CLI arguments (e.g., --gpu-memory-utilization, --max-model-len) and any hands-on confirmation that these can be set from the command line.

   LocalAI—none0/10

   The evidence shows LocalAI's CLI can run/load models (e.g., `local-ai run huggingface://...`), preload models via JSON, and auto-detects GPU backends, but there is no evidence of CLI flags or parameters for setting custom GPU offload (e.g., layer count) or context length when loading a model. Missing for 10: explicit CLI flags for GPU layer offload and context-size configuration, and any documentation/example showing these settings being passed at load time.

   CLI usage is documented (e.g., `local-ai run huggingface://...` to start a model server, `local-ai models list` to manage models), implying the server can be started via command line, but there is no explicit documentation of a stop/shutdown CLI command or process management. missing for 10: explicit stop/shutdown CLI command, lifecycle management docs (status, restart), independent confirmation of server control via CLI.
