Scheduled AI and LLM jobs
AI agents that run once aren't the interesting case. Brand monitors, daily summarisers, sentiment pipelines and recurring research are. The spokes here cover the cron behind them.
About this topic
AI & LLM
Most AI work that ships to production is event-driven (a user asks the chatbot, a webhook arrives, an upload completes). The recurring AI work (every morning, summarise yesterday's sales calls; every hour, scan brand mentions; every Monday, run the LLM-powered sentiment pass over the support queue) all needs a real schedule. The LLM platforms themselves do not ship one. OpenAI, Anthropic, Mistral and friends are pure APIs.
The spokes here are the cron pattern for that. Crontap fires your /api/ai/run endpoint at the cadence you need, in the timezone the report's audience lives in. Inside the endpoint you call the LLM API with the key, write results back, post to Slack or email when done. Per-schedule timezones matter for digests; retries matter for upstream LLM 5xxs; failure alerts surface when a summariser quietly stops working. The Llama brand monitor and OpenAI sentiment pipeline spokes are concrete examples of the pattern.

FAQ
Common questions on AI & LLM
- How does Crontap handle long-running LLM calls?
- Crontap kicks off the request and waits for the HTTP response, with a configurable timeout. For LLM calls that take longer than a typical scheduler is comfortable with, the standard pattern is an async kickoff: Crontap hits a small endpoint that queues the LLM job (e.g. into a worker, into BullMQ, into Cloud Tasks), gets a 202 immediately, and the actual LLM work happens in the background.
- Where do OpenAI API keys live?
- In your application's environment, never on the schedule. Crontap hits your endpoint with a shared-secret header; your endpoint reads the OpenAI key from env and makes the call. The schedule sees no AI-specific credentials.
- Can I avoid running an LLM job during off-hours?
- Yes. Standard cron syntax expresses 'every hour, 9-18, Mon-Fri, in Europe/London'. Crontap respects per-schedule IANA timezones so the 09:00 boundary is wall clock in London, not UTC. Off-hours are simply not in the cron expression.
