Ornith DOTResize 448 MLX BF16

This is the BF16 MLX build. The measured local artifact size is about 58 GiB. It is derived from deepreinforce-ai/Ornith-1.0-35B at revision 5df2ed3f675c7beaa490328cc70bb573b65fb660.

The model keeps the Qwen3.5-MoE/VLM structure and tokenizer/tool template, but reduces the MoE intermediate width from 512 to 448 with a support-preserving DOTResize pass. The goal of this build is to keep the 262k context metadata, coding behavior, and OpenAI-compatible tool calling while shaving memory from the original 35B BF16 artifact.

Thinking is disabled unless a runtime explicitly supplies enable_thinking=true, which prevents normal chat responses from exposing <think> delimiters or other internal wrapper tokens. The tool template is still present for runtimes that parse structured tool calls.

Variants

BF16: jedisct1/Ornith-DOTResize-448-MLX-BF16
oQ8: jedisct1/Ornith-DOTResize-448-MLX-oQ8
oQ4: jedisct1/Ornith-DOTResize-448-MLX-oQ4

Local Validation

Before upload, the BF16 artifact passed static MLX safetensor inspection, oMLX lazy load, LM Studio load at 262144 context, direct OpenAI-compatible tool-call smoke, Swival core and all-tools gates at 5/5 with zero failed tool calls, a coding smoke, and a long-context retrieval smoke at 241,934 prompt tokens.

The oQ8 and oQ4 artifacts were produced with oMLX streaming oQ quantization using text_only=false, then checked for VLM metadata preservation, quantized safetensor structure, oMLX lazy load, LM Studio load, direct tool-call behavior, and absence of visible thinking/tool wrapper tokens.

Notes

This is a derived local conversion and reduction, not a new base model. The validation above is practical smoke and integration coverage, not a replacement for a benchmark suite.
