# llm-proxy
|
||||||
|
|
||||||
|
Прозрачная прослойка OpenAI API перед RouterAI (routerai.ru). Принимает
|
||||||
|
`/v1/chat/completions` и `/v1/models`, модифицирует запрос и проксирует дальше.
|
||||||
|
|
||||||
|
## Что добавляет в запрос
|
||||||
|
|
||||||
|
1. **`provider.ignore`** — исключение дорогих провайдеров (список из env
|
||||||
|
`EXCLUDED_PROVIDERS`, напр. `deepseek`) + `allow_fallbacks: false`
|
||||||
|
(иначе ignore не жёсткий — RouterAI может уйти на исключённого резервной
|
||||||
|
попыткой).
|
||||||
|
2. **`reasoning: {"enabled": false}`** — для моделей с суффиксом `-no-think`
|
||||||
|
(отключение думанья; проверено на `deepseek/deepseek-v4-flash-0731`:
|
||||||
|
работает `reasoning.enabled=false`, не работает `include_reasoning=false`).
|
||||||
|
Суффикс снимается перед отправкой — RouterAI видит оригинальное имя.
|
||||||
|
|
||||||
|
## Каталог /v1/models
|
||||||
|
|
||||||
|
Модели, чей id содержит любую из подстрок `THINKING_MODELS`, дублируются в
|
||||||
|
каталоге с суффиксом `-no-think` (напр. `deepseek/deepseek-v4-flash-0731-no-think`).
|
||||||
|
|
||||||
|
## Конфиг (env)
|
||||||
|
|
||||||
|
| Переменная | Default | Описание |
|
||||||
|
|---|---|---|
|
||||||
|
| `PORT` | 8100 | Порт сервера |
|
||||||
|
| `UPSTREAM_URL` | `https://routerai.ru/api/v1` | Куда проксировать |
|
||||||
|
| `ROUTER_API_KEY` | — (обязателен) | Bearer-ключ RouterAI |
|
||||||
|
| `EXCLUDED_PROVIDERS` | пусто | slug'и провайдеров через запятую |
|
||||||
|
| `THINKING_MODELS` | `deepseek/deepseek-v4-flash-0731,deepseek/deepseek-v4-flash` | подстроки id «думающих» моделей |
|
||||||
|
|
||||||
|
## Сборка и деплой
|
||||||
|
|
||||||
|
- CI (Gitea Actions, на release): `./gradlew shadowJar` → образ
|
||||||
|
`images.binom.pw/llm-proxy:<tag>` (zot).
|
||||||
|
- Запуск на 76.179 (llm-router): `podman-compose up -d` из `podman-compose.yaml`
|
||||||
|
(образ тянется из `images.binom.pw`, сеть `bifrost_default` — туда же Bifrost
|
||||||
|
ходит по имени `llm-proxy`).
|
||||||
|
- Bifrost: в `config_providers` провайдера `Routerai` `network_config_json.base_url`
|
||||||
|
= `http://llm-proxy:8100` (после смены — рестарт bifrost_gateway).

/**
|

|
* Прослойка OpenAI API: принимает chat/completions, добавляет в JSON
|
||||||
|
* `provider.ignore` (исключение дорогих провайдеров) + `allow_fallbacks: false`
|
||||||
|
* и прозрачно проксирует на RouterAI (routerai.ru/api/v1). Ответ — как есть,
|
||||||
|
* включая SSE-стрим.
|
||||||
|
*
|
||||||
|
* Трюк «-no-think»: модели из [THINKING_MODELS] в каталоге /v1/models дублируются
|
||||||
|
* с суффиксом `-no-think`; запрос на такой id получает `reasoning: {"enabled": false}`
|
||||||
|
* (модель не думает — не жрёт токены на reasoning). Проверено на
|
||||||
|
* deepseek/deepseek-v4-flash-0731: reasoning.enabled=false глушит думанье.
|
||||||
|
*
|
||||||
|
* Конфиг (env):
|
||||||
|
* - PORT (default 8100)
|
||||||
|
* - UPSTREAM_URL (default https://routerai.ru/api/v1)
|
||||||
|
* - ROUTER_API_KEY — Bearer-ключ RouterAI (обязателен)
|
||||||
|
* - EXCLUDED_PROVIDERS — slug'и провайдеров через запятую (напр. "deepseek")
|
||||||
|
* - THINKING_MODELS — подстроки id «думающих» моделей через запятую
|
||||||
|
* (напр. "deepseek/deepseek-v4-flash-0731,deepseek/deepseek-r1")
