(help decide)", "summary": "A developer building a local agent harness that distributes sub-tasks to models within a 64K context window is asking the community to choose between the B70 and R9700 GPUs for the setup. The harness sequences its model \"swarm\" on 16GB of VRAM and runs one-shot calls to various models for planning and sub-tasks, with the developer noting they have already replaced their original starting models as newer ones became more capable. The current trio includes the fv78pd/gemma-4-E4B-Agentic-Opus-Reasoning-GeminiCLI-GGUF model at Q4 quantization.", "body_md": "So my harness distributes sub-tasks to agents within 64k context, with many elements to minimize context use for fluff. The models don’t have a benchmark beyond that of “do they respond through 64K, does the response error?” If they fail at the harness subtask I don’t use them.\n\nLong context tasks can always be divided, LLM’s are great at distributing and converging those segments. These models do not get long form multi hour tasks. The harness assembles the plan, task and sub-tasks with one-shot calls to various models, and the “swarm”(it’s sequenced on 16GB VRAM) handles the grunt work.\n\nI developed a spec based workflow in march that I’ve used successfully with this workflow, but we built the harness greenfield, and I’ve not even kept the starting models we began with, as newer models became more capable.\n\nCurrent trio:\n\n[fv78pd/gemma-4-E4B-Agentic-Opus-Reasoning-GeminiCLI-GGUF](https://huggingface.co/fv78pd/gemma-4-E4B-Agentic-Opus-Reasoning-GeminiCLI-GGUF) Q 4", "url": "https://wpnews.pro/news/b70-or-r9700-help-decide", "canonical_source": "https://forum.level1techs.com/t/b70-or-r9700-help-decide/250288?page=7#post_136", "published_at": "2026-09-11 12:49:55+00:00", "updated_at": "2026-09-11 13:10:31.716404+00:00", "lang": "en", "topics": ["ai-agents", "large-language-models", "ai-infrastructure"], "entities": ["B70", "R9700", "fv78pd/gemma-4-E4B-Agentic-Opus-Reasoning-GeminiCLI-GGUF", "Hugging Face"], "alternates": {"html": "https://wpnews.pro/news/b70-or-r9700-help-decide", "markdown": "https://wpnews.pro/news/b70-or-r9700-help-decide.md", "text": "https://wpnews.pro/news/b70-or-r9700-help-decide.txt", "jsonld": "https://wpnews.pro/news/b70-or-r9700-help-decide.jsonld"}}
