Langdock

Langdock is a DSGVO-compliant AI platform that routes requests to OpenAI, Anthropic, and Google Gemini through a single unified API. By installing the Langdock Provider Plugin, all CoPilot AI requests are routed through Langdock instead of directly to the providers. This gives you a single API key, EU or US data residency, and DSGVO-compliant usage of LLMs.

Installation
ddev composer require samuelreichor/craft-co-pilot-landock &&
ddev craft plugin/install co-pilot-landock
Models
All models from OpenAI, Anthropic, and Google Gemini available in your Langdock workspace
Data Residency
EU or US
Strengths
Single API key for all providers, DSGVO-compliant, centralized model management

Benchmark

We ran 9 real-world content scenarios (field editing, nested matrix, translations, entry creation, batch operations, multi-site, propagation, and search) against each provider. Here are the results:

Premium Models

Provider / ModelAvg. ScoreAvg. Duration
OpenAI (gpt-5.4)100%27.4s
Anthropic (claude-opus-4-6)100%52.5s
Gemini (gemini-3.1-pro-preview)96.3%58.0s

Budget Models

Provider / ModelAvg. ScoreAvg. Duration
OpenAI (o4-mini)87.8%149.8s
Anthropic (claude-sonnet-4-6)95.6%40.8s
Gemini (gemini-2.5-flash)91.9%23.3s

Note

Anthropic uses significantly fewer tokens per request due to prompt caching, which makes it very cost-efficient despite higher per-token pricing. Gemini's budget models offer the fastest response times. Scores reflect correctness of the final result across all scenarios.
