# Open-Source AI Inference Frameworks DeepSeek’s ‘DeepInfer’ Runs ‘V4.1-Flash’ at Lower Cost By Adam Harrie | Written with AI assistance | Published 2026-10-21 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/open-source-ai-inference-frameworks References: [gizmodo](https://gizmodo.com/deepseek-dials-up-the-pressure-on-openai-and-anthropic-with-open-source-inference-tool-2000828261)  DeepSeek is expanding access to [open-source inference tools](https://www.trendhunter.com/trends/ensemble-ai) with ‘DeepInfer,’ a free framework designed to run its ‘V4.1-Flash’ model. It gives AI teams a way to deploy trained models for output generation while aiming to reduce compute use, energy demand and overall operating costs. The tool currently supports only ‘V4.1-Flash,’ with future models to be added as they become available. DeepSeek also highlights speculative decoding, a method that speeds up generation by predicting likely next steps before confirming them. At $0.035 per million input tokens, ‘V4.1-Flash’ sits well below many frontier-model prices and makes [cost control](https://www.trendhunter.com/trends/freepass-ai) a core part of the product story. That pricing turns inference into a sharper competitive lever, especially for businesses weighing closed systems against cheaper [open-source alternatives](https://www.trendhunter.com/trends/gemma-4).
