Ornith 1.5 35B Q8 improves one local coding sample

Summary A hands-on browser-OS task found the Q8 quant more complete than Q4.

The details

  • The test compares Ornith 1.5 35B-A3B Q4_K_M and Q8 GGUF quantizations in the Pi harness on an RTX 6000 Pro.
  • Both quantizations use publisher-provided files.
  • In the browser-OS task, Q8 used 41% of a 262K-token context window, versus 19% for Q4.
  • The reviewer reports Q8 as the more complete result.
  • Q8 produced a richer settings interface, animated wallpapers, and a more functional generated game; Q4 finished first.
  • The single hands-on source is not a controlled benchmark and provides no aggregate pass rates, latency, or hardware-wide measures.

Inference Stacks Change Local LLM Behavior

Summary Level1Techs experiment says runtime choices can materially change locally served model behavior.

The details

  • Use benchmarks that reflect real use: long-context, tool-calling, and domain-specific workloads, not only a few zero-shot prompts.
  • It defines KL divergence as directional logit-distribution drift from a baseline, not a direct measure of model intelligence.
  • Quantization KL claims require reference checkpoints, runtime environment, and calibration text.
  • They also require context lengths, sampled positions, KL direction, vocabulary handling, and aggregation method.
  • Attention-backend testing used the official BF16 27B checkpoint on an RTX PRO 6000 Blackwell GPU.
  • It used a BF16 KV cache, TP=1, eager execution, and 2,000-token chunked prefill.
