ModelLanguage (C#)

.NET bindings for model-language — a typed, safe template language for AI-agent prompts. Runs the exact same engine as the JavaScript/TypeScript package via an embedded WebAssembly module: byte-for-byte identical output, guaranteed by a shared conformance suite.

▶ Live demo — try the language in a Tiptap editor (live validation, autocomplete, real-time render), powered by the same engine.

Filters format values — dates, numbers, text:

{{ user.created_at | date: "MMM D, YYYY" }}            →  Jul 5, 2026
{{ user.created_at | date: "h:mm A", "Europe/Kyiv" }}  →  5:37 PM
{{ user.last_seen  | time_ago }}                       →  3 days ago

using ModelLanguage;
using System.Text.Json.Nodes;

using var engine = new Engine();
var data = JsonNode.Parse("""{ "user": { "name": "Vasyl" } }""");
var res = engine.Render("Hi {{ user.name | default: \"there\" }}!", data);
Console.WriteLine(res["text"]); // Hi Vasyl!
  • Render(template, data?, schema?, options?) → { text, warnings, resolvedBranches, directives, tokenEstimate }
  • Validate(template, schema?, options?) → { diagnostics, maxTokenEstimate }
  • Parse(template) → { ast, diagnostics }

Never throws for template problems — they degrade to empty output plus a warning. Pass options.now (epoch ms) for datetime filters.
