Built-In Tools vs Custom Tools in LLM Agents
In an AI agent, a tool is anything the model can ask to use, like a search engine, a database lookup or a shell command. The model does…

Can Provider Routing Change LLM Outputs?
Provider routing can change an LLM's output when a request reaches a different model version, fallback model, parameter configuration, precision level, inference engine, region, or runtime environment. Provider…
Read articleCan Tokenizer Changes Affect LLM Output?
Yes. A tokenizer converts text into a sequence of integer identifiers called token IDs before a large language model (LLM) processes it. A token might represent a whole…
Read articleDo Structured Outputs Make LLM Responses Deterministic?
No. For a large language model (LLM), structured outputs make responses more predictable in format, not necessarily in content or execution. A structured output is data generated to…
Read articleDoes Setting a Seed Make LLM Output Reproducible?
No. A seed can improve repeatability, but it does not guarantee identical large language model (LLM) output. It initializes the pseudorandom number generator used in token sampling; it…
Read articleHow Does Mixture-of-Experts Routing Affect LLM Repeatability?
If you send the same prompt to a mixture-of-experts (MoE) model several times at temperature 0, the answers can still differ. Routing is one possible reason. In each…
Read articleHow Floating-Point Determinism Affects LLM Reproducibility
Running the same prompt through the same LLM does not always give the same output, even with temperature 0 and a fixed seed. One reason is floating-point arithmetic.…
Read articleHow Model Updates Break LLM Reproducibility
A large language model (LLM) generates text, structured data, code, or tool calls from prompts. Hosted LLMs are not fixed functions of prompt text: providers can change models,…
Read articleHow Much RAM Does a Vector Database Like Qdrant Need?
When you size a Qdrant server, the number of vectors alone does not tell you how much RAM to buy. RAM use depends on each vector’s dimensions and…
Read articleHow Prompt Caching Works and Why Cached Input Pricing Drives Coding Agent Costs
A coding agent usually makes multiple model calls as it inspects files, edits code, and runs tests. Each call can include the conversation so far, from instructions and…
Read articleHow to Handle Conflicts Between Stored Agent Memory and Fresh Retrieval
An AI agent can save details from earlier conversations, such as a user’s preference or a project decision, and fetch documents or database records to answer a new…
Read articleHow to Roll Out a New LLM Model Version Safely
A new LLM version changes how your production system behaves, even if the model name is the only setting you change. It might be more accurate overall and…
