Ollama can retain a model after a request, let it expire, or unload it immediately. Those choices trade warm-request latency for memory headroom. In an isolated Ollama v0.32.13 CPU run, the same pinned request reported load_duration of 858,726,192ns when cold and 77,440,653ns when warm. Immediate unload then ...
The reproduced stream completed its HTTP body and ended with data: [DONE], yet it contained zero usage chunks. That is a successful transport result and an unusable billing result.
Accept a streamed request as a usage receipt only when the client requested stream_options.include_usage, exactly one non-null usage object ...
Repository coordinates on Hugging Face are a mutable address, not a release identity. If a service downloads main during every cold start, two replicas launched on different days can receive different model files even though their configuration names the same repository. A warm cache may hide that ...
A fluent answer cannot prove that Retrieval-Augmented Generation found the right evidence. The generator may write confidently from incomplete context, while a weak answer can also waste a perfectly good retrieval result. Measure retrieval before blaming the model.
For an offline regression test, label which document IDs are ...
GPU memory planning starts with one equation: required VRAM = model weights + KV cache + runtime reserve. A checkpoint that fits by file size can still fail when several requests hold long contexts, while a model that loads successfully can still miss its latency target. The ...
Sequence group ... is preempted by PreemptionMode.RECOMPUTE mode because there is not enough KV cache space. That warning does not mean the vLLM process has crashed or the GPU is out of all memory. It means the scheduler could not keep every active sequence's key-value state in ...
An AI agent asks a tool to create a DNS record. The provider accepts the change, but the HTTP response disappears before the worker receives it. Ten seconds later, the orchestration layer sees a timeout. That timeout proves only that the caller lacks a result. It does ...
Sticky sessions are not a universal MCP requirement anymore. A remote Model Context Protocol client speaking 2026-07-28 sends self-describing requests that may reach any compatible replica, while a 2025-era Streamable HTTP client can still depend on Mcp-Session-Id and server-local session state. Removing affinity before identifying which contract ...
Raw vector bytes are only the first line in a Qdrant storage budget. A collection also carries payload, payload indexes, vector indexes, write-ahead records, segment metadata and point versions. During optimization, readable source segments can coexist with rebuilt segments and concurrent changes. A disk plan that ends ...
nvidia-smi can show a healthy GPU while an Ollama request still runs partly—or entirely—on CPU. That contradiction does not have one universal cause. The loaded model's PROCESSOR field is the starting evidence: it separates full GPU placement, full CPU placement and a mixed split before you touch ...
