Anyone running Qwen3.5-9B locally with Hermes?
I’ve been doing some experiments with a modified Qwen3.5-9B runtime on a 4090. I’m testing a mapped/tiered KV setup where most old context (90%) can sit in normal RAM, while the GPU keeps a small hot working set and only pulls back the regions it actually needs.
I'm still new to Hermes but I've used LM Studio and Ollama a lot.
The main objective is to add massive kv cache runway to local processes.
My Setup / context
- RTX 4090, 24 GB VRAM
- Ryzen 9 7900X
- 64 GB system RAM
- Windows 11
- Running local models regularly
- Current test model: Qwen3.5 9B
- Running the 9B in bf16 for the current experiments
- Also already running Qwen3.8 27B Q8_0 in LM Studio, but it is a tight fit on 24 GB VRAM
- Interested in Hermes as an actual local agent environment, not just one off chat inference
- Main concern: longer running agent sessions and context growth on consumer hardware
Questions for Qwen3.5-9B / Hermes users
- Anyone running Qwen3.5 9B locally with Hermes?
- What hardware are you using?
- What quant are you using?
- What context size do you normally run?
- How does it behave once sessions get genuinely long?
- Does KV/VRAM pressure become a problem for you?
- Do you reduce context because of VRAM?
- Do you notice tokens/sec dropping as context grows?
- How is Qwen3.5 9B for long running agent sessions?
- How is its tool use?
- How is instruction following?
- How is coding?
- How well does it retain information from far back in a session?
- Any failure modes that only show up after long conversations?
- Anyone compared 9B with the 4B or 27B in Hermes?
- Anyone using CPU/RAM KV offload already?
- If so, how bad is the PCIe/latency penalty?
I don't expect anyone to answer all of these questions but any responses are appreciated.
