CLI — Models & languages
check-models
Synopsis: ai-i18n-tools check-models
Validate each configured model id against the active provider's GET /models list (membership and expiration_date). Requires that provider's API key (none for keyless providers like Ollama). Exits non-zero when any configured id is missing or expired, and respects the resolved request timeout (requestTimeout or requestTimeoutMs on the provider, otherwise the top-level value). When the provider returns pricing (e.g. OpenRouter), also shows USD per 1M tokens for prompt/completion.

list-models
Synopsis: ai-i18n-tools list-models
List every model the active provider advertises via its GET /models list (sorted by id; active provider follows the config provider key, override with -P / --provider). Requires that provider's API key (none for keyless providers like Ollama). When the provider returns pricing (e.g. OpenRouter), also shows USD per 1M tokens for prompt/completion, and tags entries past expiration_date.
Key options: -P / --provider

bench-models
Synopsis: ai-i18n-tools bench-models [--model <ids>] [--text <text> | --file <path>] [--source <locale>] [--target <locale>]
Benchmark each configured model by translating one sample in isolation (single-model client, no fallback chain). Prints a table of model id, input/output tokens, wall-clock translation time, and USD cost (— for providers that do not report cost), plus a totals row and per-model failures.
Models default to the union of the active provider's translationModels, uiModels, and localeModels ids (override with --model); the sample defaults to a built-in English markdown block (override with --text / --file); source/target default to config sourceLocale and the first docs[] target locale, falling back to the top-level targetLocales (override with --source / --target). Runs models in parallel, bounded by config concurrency (default 4); each model is still timed individually. Requires the active provider's API key.
Key options: --model, --text, --file, --source, --target
list-languages
Synopsis: ai-i18n-tools list-languages [search]
List the bundled UI languages catalog (data/ui-languages-complete.json) as a human-readable table (code, text direction, English name, native name). Needs no config or API key. Pass an optional search term to keep only entries whose code, native name, English name, or direction contain it (case-insensitive), e.g. list-languages portuguese, list-languages rtl, list-languages zh.
