Token Usage & Cost Monitoring
13 posts on token usage & cost monitoring — part of developer tools on the n4n AI blog.
Why token counts differ between LLM providers
Analyze why token counts differ between providers: tokenizer variants, chat templates, hidden reasoning tokens, and accounting rules affect LLM cost tracking.
Tracking per-user LLM spend in a multi-tenant app
Step-by-step per-user LLM spend tracking for multi-tenant apps: instrument OpenAI-compatible calls, store token usage, and reconcile retries without leaks.
Token counting methods: tiktoken vs provider-reported usage
Practical comparison of tiktoken vs provider-reported token usage for LLM cost monitoring: accuracy, latency, limits, and which method to choose per use case.
Setting spend alerts before your LLM bill surprises you
Set up LLM spend alerts with token metering and cron jobs to avoid surprise bills. Step-by-step guide with runnable Python code for OpenAI-compatible gateways.
Per-model cost dashboards for cheapest-provider routing
Learn how to build per-model cost dashboards routing to compare provider prices and automate cheapest-provider routing for LLM workloads with practical code.
Monitoring cost anomalies across fallback provider chains
Learn how to detect and alert on cost anomalies fallback provider chains by metering per-token usage and tracing routing across LLM providers.
How caching affects token usage and cost reporting
Analyze how prompt caching changes token counts and cost reports. Learn to parse cache usage, avoid metering errors, and build accurate LLM spend tracking.
Forecasting monthly LLM spend from daily token trends
Learn how to build a reproducible pipeline for forecasting monthly LLM spend from daily token trends using usage logs, pricing tables, and time series.
Dashboards for tracking prompt vs completion token costs
Build prompt vs completion token cost dashboards that attribute spend correctly: log usage events, join pricing, aggregate by model, and avoid cache blind spots.
Cost per request: GPT-4o vs Claude vs Llama pricing
Compare cost per request GPT-4o Claude Llama across capabilities, pricing, latency, and ergonomics to choose the right model for your LLM workload.
Building a token usage dashboard for GPT-4o and Claude
Hands-on tutorial to build a self-hosted token usage dashboard for GPT-4o and Claude with Python, SQLite, and Flask for real-time LLM cost tracking.
Building a real-time LLM cost monitor with Grafana
Hands-on tutorial: build a real-time LLM cost monitor Grafana stack using Prometheus to scrape token usage and plot live spend from Python apps.
Attributing LLM spend to features, not just API keys
Practical guide to attributing LLM spend to features instead of API keys: tag requests, centralize metering, and query cost by product surface.
