Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

lmstudio-api scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

LM Studio API

Проверено вживую на LM Studio 0.4.x, 2026-08-07, локальный сервер на порту 1234 (AMD Strix Halo, 128 ГБ единой памяти). Замеры в конце - на qwen3-vl-30b-a3b-instruct.

Три поверхности API

Поверхность Путь Назначение
OpenAI-совместимая /v1/* инференс: chat/completions; models отдает только КАТАЛОГ скачанных
Нативная v0 (устаревшая) /api/v0/* models с полем state; управления моделями нет
Нативная v1 /api/v1/* с LM Studio 0.4.0, рекомендуемая: инференс + управление моделями

Anthropic-совместимые эндпоинты тоже заявлены в доках, не проверялись.

Эндпоинты v1

POST /api/v1/chat                      (НЕ /api/v1/chat/completions)
GET  /api/v1/models
POST /api/v1/models/load
POST /api/v1/models/unload
POST /api/v1/models/download
GET  /api/v1/models/download/status

load: обязателен model - точный ключ модели. Опционально context_length, eval_batch_size, flash_attention, num_experts, offload_kv_cache_to_gpu, echo_load_config. Всегда ставить echo_load_config: true - ответ вернет фактически примененный конфиг, и сразу видно, что сервер проигнорировал.

Ответ: {"type", "instance_id", "load_time_seconds", "status": "loaded", "load_config": {...}}. Вызов БЛОКИРУЮЩИЙ - возвращается по факту загрузки, отдельно опрашивать готовность не нужно.

unload: обязателен instance_id, НЕ имя модели. Берется из loaded_instances[].id ответа GET /api/v1/models.

GET /api/v1/models отдает {"models":[...]} с полями key, type, publisher, architecture, quantization, size_bytes, max_context_length, capabilities, loaded_instances[]. У инстанса - id и config с фактическими context_length, parallel, flash_attention, eval_batch_size, num_experts и прочим. Пустой loaded_instances = модель не загружена.

Инференс: два эндпоинта, и они НЕ равнозначны

/v1/chat/completions (OpenAI) /api/v1/chat (родной)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
