10 guides · No paywall
HF API token security: protect credentials, prompts, and actions
Keep credentials out of browsers, narrow permissions, minimize logs, and require authorization before models act.
AI trading research: build a workflow you can challenge
Use models for bounded research while preserving evidence, point-in-time data, testing discipline, and review.
Inference Providers vs dedicated endpoints: a practical decision guide
Compare hosting routes through workload, cost per accepted task, deployment control, and operating responsibility.
Streaming APIs: choosing SSE or WebSocket with recovery in mind
Choose a transport by communication pattern, then design event parsing, partial states, backpressure, and reconnects.
High frequency API design: deadlines, queues, and reliable throughput
Design an API around useful throughput, bounded queues, operation-aware retries, and tail latency.
How to choose HF models for a production-minded application
Turn model cards, task requirements, licensing review, and evaluation fixtures into a defensible shortlist.
HFT API architecture: keep research outside the execution path
Explore market-data freshness, pre-trade controls, order state, reconciliation, and independent stop mechanisms.
Hugging Face API quickstart: from token to a validated response
Connect a model safely with a clear task, protected credentials, bounded requests, and response validation.
LLM caching and batching: optimize without losing correctness
Separate response caching, prefix reuse, and batching while protecting freshness, authorization, and task quality.
