The core insight was that even with approved language lists, probabilistic models could still generate responses in the wrong language. The solution centers on a shared Localization Context established once by the Planner and consumed across all distributed components — planners, retrieval systems, actions, and response generators. Language detection uses Lingua, a Rust-based library achieving ~3–4ms p95 latency, avoiding costly LLM inference calls. The system now handles over 600,000 daily language detections across 34 fully supported languages, with mid-conversation language switching handled by treating Localization Context as live shared state rather than static configuration. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why can't you just tell an LLM which language to respond in and expect consistent behavior? Explicitly specifying a target language or providing an approved language list is not enough because the model can still generate output in a different language, sometimes outside the approved set entirely. This is a control problem, not a translation quality problem, since language selection also affects retrieval, action execution, and downstream workflows, so an early mistake propagates through the whole pipeline. _Teams shipping multilingual AI agents follow architecture writeups like this via daily.dev to avoid the same drift failures._ ### What library does Salesforce use for fast language detection in Agentforce and how fast is it? Agentforce uses Lingua, a language-detection library built on Rust bindings and optimized for short conversational text, achieving approximately 3-4 milliseconds of p95 latency without requiring an additional model invocation. This was chosen after evaluating multiple approaches, including LLM-based inference, because detection needed to be effectively invisible to avoid the hesitation that erodes user trust in conversational systems. _Engineers picking a low-latency detection library for chat products can track approaches like this on daily.dev._ ### How does Agentforce keep language consistent across planners, retrieval, and parallel actions in a single response? Agentforce establishes a Localization Context once per interaction, and the Planner updates it as live shared state that all downstream planners, retrieval systems, and actions consume through a shared contract, rather than each component independently inferring language. This prevents mixed-language responses that previously occurred when one action localized correctly while a parallel action fell back to English. _Anyone architecting distributed agent workflows can follow patterns like shared localization state on daily.dev._ ## Similar posts on daily.dev -
