Ollama's context length defaults are confusing and silently truncate conversations
Ollama's default context length is inconsistently documented and applied across different configurations. The documentation presents at least three conflicting default values: 2048 in the Modelfile reference, variable lengths (4k, 32k, 256k) based on available VRAM, and a value …

Ollama create: A deep dive into building custom LLMs
Ollama's `create` command functions as a model compiler, taking a Modelfile to construct custom language models. It resolves the base model, processes instructions into content-addressed layers, and generates a manifest. This layer-based approach allows for efficient rebuilding,…

Load testing embedding endpoints requires batch size analysis, not just RPS
This article discusses the nuances of load testing embedding endpoints, highlighting that requests per second (RPS) is an insufficient metric. It explains that batch size significantly impacts throughput and latency, as fixed per-request overhead is amortized over more items. Th…

Load testing LLM agents requires timing the full loop, not just API calls
This article details how to effectively load test concurrent tool-calling requests for LLM agents, emphasizing the need to measure the entire agent loop rather than just individual API calls. It explains that a single user-visible request for an agent involves multiple model int…
