The first version owns only AI job lifecycle and metrics. Business data stays in domain services such as telephony, monitoring-tg and monitoring-pf.

Generic job contract

The service is intentionally domain-agnostic:

owner_service names the caller, for example telephony, monitoring-tg, monitoring-pf or a future Portal module.
owner_ref is the caller's stable object reference, for example beeline/{call_id} or channel/{message_id}.
task_type describes the technical task class, for example transcribe, call_analysis, tg_analysis, pf_competitor_analysis.
model_profile selects a runtime profile, for example whisperx, qwen2.5-14b, vision, or a future provider profile.
input and result are JSON payloads owned by the caller and worker.

This keeps AI service as shared infrastructure rather than a telephony-specific service.

Built-in workers

The first built-in worker processes llm_chat and chat_completion jobs whose model_profile equals LLM_MODEL.

Input can be either explicit messages:

{
  "messages": [
    {"role": "system", "content": "Answer as JSON."},
    {"role": "user", "content": "Classify this text"}
  ],
  "max_tokens": 256
}

or compact system / user fields. The completed job result contains content, model, usage and duration_ms.

API

POST /api/v1/jobs creates one job.
POST /api/v1/jobs/batch creates many jobs with shared defaults.
POST /api/v1/jobs/claim atomically claims pending jobs for a worker.
GET /api/v1/jobs/{id} returns technical job state and result.
POST /api/v1/jobs/{id}/complete stores a successful job result.
POST /api/v1/jobs/{id}/fail stores a failed job category and message.
POST /api/v1/jobs/{id}/retry resets failed/running jobs to pending.
GET /api/v1/stats returns queue and error counters.
GET /api/v1/providers/status checks configured AI providers without returning secrets.
GET /healthz returns process health.
GET /readyz checks PostgreSQL readiness.

Configuration

HTTP_HOST, default 0.0.0.0
HTTP_PORT, default 8080
DATABASE_URL, required
MIGRATE_ON_START, default true
LLM_BASE_URL, primary OpenAI-compatible LLM endpoint
LLM_API_KEY, primary LLM API key
LLM_MODEL, default qwen2.5-14b
LLM_TIMEOUT, default 5m
WHISPERX_URL, WhisperX endpoint for transcription jobs
WORKER_ID, default hostname
WORKER_POLL_INTERVAL, default 2s
WORKER_CLAIM_LIMIT, default 4

Next integration step

telephony should first mirror low-risk analysis jobs into this service while continuing local processing. Remote execution can then be enabled by feature flag per task type.
