The optional local server has no credential, its current routes aren't in the published REST reference, and telemetry is on by default with an opt-out.\n\n**LM Studio.** OpenAI-compatible chat completions, responses, completions and embeddings, Anthropic-compatible /v1/messages and a native /api/v1, all on one port. Authentication is off by default, so any local process can call the server.\n\n## Before you call either\n\n### Foundry Local\n\n1. Read the server URL from `manager.urls[0]` or `foundry server status`. The port is dynamic unless the owner sets `web.urls` or `foundry server start --port`\n2. Send the model ID that `GET /v1/models` returns, not the alias. The alias resolves to a hardware-specific variant\n3. Check `supportsToolCalling` before sending tools. Support differs by variant, and issue #1183 reports Qwen tool calling failing on QNN\n4. Set your own request timeout. Inference has no built-in one, and cancellation takes effect only after the current generation step\n5. Ask the owner to set `ORT_TELEMETRY_DISABLED=1` or `disableNonessentialTelemetry` before the manager is created if telemetry must be off\n\n### LM Studio\n\n1. Send `Authorization: Bearer $LM_API_TOKEN` when the owner gives you a token. With Require Authentication on, every request needs it\n2. Pass `previous_response_id` to /api/v1/chat instead of resending the history, and `store: false` for one-off calls\n3. List models with `GET /api/v1/models` before naming one. A named model that's downloaded loads just in time\n4. Install the Python SDK pre-release (1.6.0b1) and pass `api_token` directly. It reads `LMSTUDIO_API_TOKEN`, not the `LM_API_TOKEN` the docs name\n5. Set `allowed_tools` on every MCP integration. Without it the model sees every tool on the server\n\n## Questions\n\n### Which is better for AI agents, Foundry Local or LM Studio?\n\nFoundry Local scores 60.5 (C) on agent readiness against LM Studio's 57.8 (C), and leads in 3 of 7 scored categories. LM Studio leads on schema \u0026 documentation, agent ergonomics and security \u0026 auth.\n\n### Can an agent call Foundry Local and LM Studio without installing anything?\n\nNo hosted endpoint is listed for Foundry Local. No hosted endpoint is listed for LM Studio.\n\n### Are Foundry Local and LM Studio open source?\n\nFoundry Local is open source (MIT for the SDKs and the v2 native runtime. The CLI is closed source under Microsoft Software Licence Terms. Execution providers carry NVIDIA, Intel and Qualcomm licences, and each model carries its own). No open-source release is listed for LM Studio.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/foundry-local-vs-lm-studio.json, and with the fewest tokens: https://www.anchorterminal.com/compare/foundry-local-vs-lm-studio.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"foundry-local\", \"b\": \"lm-studio\"}`.
