The training recipe points the same way: the effort went into controlling answer length, memory footprint and time to first token, more than into making the model smarter.","published_at":"2026-10-27T04:00:00.000Z","updated_at":"2026-10-27T04:00:00.000Z","record_date":"2026-10-27","topics":["memory","agents","reasoning"],"source_urls":["https://ollama.com/library/nemotron-3.5-bolt","https://research.nvidia.com/labs/nemotron/files/NVIDIA-Nemotron-3.5-Bolt-E4B-4GB-Technical-Report.pdf","https://huggingface.co/nvidia/NVIDIA-Nemotron-3.5-Bolt-E4B-4GB","http://developer.nvidia.com/factory-operations-blueprint-early-access","https://developer.nvidia.com/factory-operations-blueprint-early-access","https://research.nvidia.com/labs/nemotron/NVIDIA-Nemotron-3.5-Bolt-E4B-4GB"],"language":"en","routes":{"html":"https://newruntime.com/analysis/nvidia-tuned-bolt-e4b-to-answer-fast-in-4-gb-not-to-beat-gemma-on-raw-capability/","markdown":"https://newruntime.com/analysis/nvidia-tuned-bolt-e4b-to-answer-fast-in-4-gb-not-to-beat-gemma-on-raw-capability.md","json":"https://newruntime.com/analysis/nvidia-tuned-bolt-e4b-to-answer-fast-in-4-gb-not-to-beat-gemma-on-raw-capability.json"},"author":{"role":"author","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"editorial_provenance":{"desk":"authorial","target_ref":"story_cluster:nvidia-nemotron-3-5-bolt-e4b-arrives-on-ollama-675853f5dfad","authorial_article_id":"596e105c-4212-41f6-99c8-7b65a73d25a7"},"next_reads":[{"type":"topic","path":"/topics/memory/","url":"https://newruntime.com/topics/memory/","title":"Memory","reason":"Explore the memory topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/memory.md","json_url":"https://newruntime.com/topics/memory.json"},{"type":"topic","path":"/topics/agents/","url":"https://newruntime.com/topics/agents/","title":"Agents","reason":"Explore the agents topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/agents.md","json_url":"https://newruntime.com/topics/agents.json"},{"type":"topic","path":"/topics/reasoning/","url":"https://newruntime.com/topics/reasoning/","title":"Reasoning","reason":"Explore the reasoning topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/reasoning.md","json_url":"https://newruntime.com/topics/reasoning.json"},{"type":"collection","path":"/analysis/","url":"https://newruntime.com/analysis/","title":"Analysis","reason":"Open the latest authorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/analysis.json"},{"type":"collection","path":"/source-ledger.json","url":"https://newruntime.com/source-ledger.json","title":"Source Ledger","reason":"Inspect the public source evidence graph.","media_type":"application/json"}]}
