| I've been experimenting with running an LLM not as a chatbot but as the core runtime of a business system, and I'm curious how others approach this. The idea is that the model doesn't just answer questions but orchestrates tools and interacts with real application logic. The architecture I'm currently testing includes: Runtime tool orchestration
parallel tool execution
loop detection
circuit breaker / timeout guards
token budgeting
Context context compression
dynamic token ceiling
Caching deterministic LLM response cache
semantic cache using pgvector
Memory short-term session memory
longer-term semantic memory
Evaluation prompt evaluation set to test tool reasoning and failures
I'm trying to figure out which parts are actually necessary in production and which ones are over-engineering. For people building LLM systems beyond simple chat interfaces: how do you handle tool orchestration?
do you implement memory layers or just rely on context?
are semantic caches worth it in practice?
Curious to hear how others structure this. |
