Qwen3.5-0.8B-OCPI

Finetune packaging of Qwen/Qwen3.5-0.8B as a full-weight OCPI operator field (not digests-only).

Method

This is an operator-field finetune packaging (method OCPI_FIELD in adapter_config.json): full base weights re-encoded for carrier/runtime use with projection ledger fidelity proofs. It is not a LoRA adapter.

Files

• model.safetensors — full f16 weights (export from OCPI field)
• config.json, tokenizer files — inference config
• adapter_config.json — hub-facing finetune metadata
• Optional companion: ocpi_field/ (binary lattice + events)

Multi-arch runtime

Standalone Rust binary ocpi-qwen is published for:

• Windows: x86_64, i686, ARM64
• Linux: x86_64, i686, aarch64
• macOS: x86_64 + Apple Silicon with Metal feature
