From e2a82b5a10680d91172577c8d1a3f98a230592ef Mon Sep 17 00:00:00 2001 From: Daniel Han Date: Fri, 15 May 2026 03:45:41 +0000 Subject: [PATCH 01/16] guardrail: detect silent 4-bit / 8-bit quantization bypass (#5344) Some users report that load_in_4bit=True is silently ignored on certain checkpoints and the model is loaded in full precision. This adds a post-load guardrail in FastBaseModel.from_pretrained and FastLlamaModel.from_pretrained that detects two failure modes and emits a clear warning instead of letting the user discover the issue via a confusing VRAM blow-up. 1. Total bypass: load_in_4bit=True requested, zero bitsandbytes Linear4bit / Linear8bitLt modules in the loaded model. Usually a transformers / bnb version mismatch or a backend-incompatible device_map. 2. Partial bypass: bnb quantized nn.Linear but a large fraction of weight bytes live in non-nn.Linear Parameters that are not in the bnb skip list. This catches the Gemma-4 MoE class where Gemma4TextExperts stores experts as fused 3D nn.Parameter tensors for torch._grouped_mm; bnb's replace_with_bnb_linear only swaps nn.Linear instances, so the fused expert weights stay in BF16 and dominate the VRAM footprint. The warning names the worst offenders so the user can correlate. warnings.warn (not raise) so CPU / MLX / AMD-without-bnb backends that legitimately have no Linear4bit modules are not broken. Tests in tests/test_issue_5344_guardrail.py cover both branches plus the full-finetuning, no-quant, and skip-list cases.

This adds an opt-in helper that walks the loaded model, finds every Gemma4TextExperts module, slices each fused (E, O, I) Parameter into E individual bnb.nn.Linear4bit modules (per-expert), and patches forward to dispatch per-expert instead of via torch._grouped_mm. Trade-off: - VRAM win: 46 GB -> 14.27 GB resident on unsloth/gemma-4-26B-A4B-it (B200, transformers 5.5.0, single GPU). Linear4bit count 206 -> 7886. Forward-pass cosine similarity vs BF16 reference is 0.994 on a fixed prompt, i.e. standard QLoRA fidelity. - Throughput loss: per-expert dispatch loses the grouped_mm speedup. Acceptable for "model fits at 4-bit on a single GPU"; QLoRA training still needs the matching per-expert LoRA path which is not in this PR. Gated on UNSLOTH_GEMMA4_MOE_4BIT=1, default off until the per-expert LoRA path lands (the swap renames gate_up_proj -> gate_up_proj_4bit which would break unsloth_zoo's grouped_mm LoRA extractor as-is). The renamed attributes also make the helper idempotent: re-entering it sees `_unsloth_gemma4_moe_4bit_swapped` and no-ops, so multiple calls across nested loaders are safe. No regression on non-MoE checkpoints: the helper only touches modules that are isinstance(Gemma4TextExperts) with the expected 3D shape. Tests cover env-var gating, no-op behaviour on non-Gemma4 models, the transformers-without-gemma4 ImportError path, and idempotence on a stub Gemma4TextExperts module.

Block is appended purely additively; the prior `# Attach dispatch hooks` comment and `_attach_bnb_multidevice_hooks` import (added earlier for multi-GPU bnb dispatch hardening) are preserved untouched so that protection is not regressed. - Count torch.int8 alongside torch.uint8 as quantized payload; bnb Linear8bitLt / Int8Params stores 8-bit weights as int8 post-cuda, so the previous accumulator zeroed and false-fired the partial warning. - Tighten partial-bypass condition to require quantized_bytes > 0, so the warning only fires when quantization actually produced payload. - Drop the overbroad "mlp.gate" skip pattern; it suppressed fused/custom mlp.gate_proj / mlp.gate_up_proj bulk weights that are exactly the partial-bypass shape this guard must report. Standard Linear4bit gate_proj weights are uint8 and counted as quantized earlier, so no new false positive on healthy 4-bit loads. - Use the real bnb class name (Linear8bitLt) in the 8-bit total-bypass message instead of synthesising "Linear8bit". - Accept an optional quantization_config so callers passing BitsAndBytesConfig directly (loader.py sets load_in_4bit_kwargs=False in that path) still get the bypass check. - Drop a duplicate transformers_version import in vision.py. --- unsloth/models/llama.py | 13 ++++++++++++- unsloth/models/vision.py | 20 ++++++++++++++------ 2 files changed, 26 insertions(+), 7 deletions(-) diff --git a/unsloth/models/llama.py b/unsloth/models/llama.py index 565d76c57f..dc1cf17482 100644 --- a/unsloth/models/llama.py +++ b/unsloth/models/llama.py @@ -2478,6 +2478,16 @@ class FastLlamaModel: and not _head.weight.is_floating_point() ): _head.to(dtype) + # Guardrail: warn before dispatch hooks if quantization was silently dropped. + from unsloth.models.vision import _warn_if_quantization_silently_dropped + + _warn_if_quantization_silently_dropped( + model, + load_in_4bit = load_in_4bit, + load_in_8bit = kwargs.get("load_in_8bit", False), + full_finetuning = kwargs.get("full_finetuning", False), + quantization_config = kwargs.get("quantization_config"), + ) # Attach dispatch hooks for bnb multi-device loads. from unsloth.models.vision import _attach_bnb_multidevice_hooks @@ -2510,7 +2520,8 @@ class FastLlamaModel: model, load_in_4bit = load_in_4bit, load_in_8bit = kwargs.get("load_in_8bit", False), - full_finetuning = full_finetuning, + full_finetuning = kwargs.get("full_finetuning", False), + quantization_config = kwargs.get("quantization_config"), ) _attach_bnb_multidevice_hooks( model, diff --git a/unsloth/models/vision.py b/unsloth/models/vision.py index 671e31a68c..6cc3469bf7 100644 --- a/unsloth/models/vision.py +++ b/unsloth/models/vision.py @@ -68,7 +68,6 @@ from unsloth_zoo.patching_utils import patch_model_and_tokenizer from unsloth_zoo.training_utils import prepare_model_for_training from unsloth_zoo.utils import Version -from transformers import __version__ as transformers_version import types import functools @@ -117,7 +116,6 @@ _GUARDRAIL_SKIP_PATTERNS = ( "merger", "modality_projection", "router", - "mlp.gate", "block_sparse_moe.gate", "mamba", "audio_tower", @@ -139,6 +137,7 @@ def _warn_if_quantization_silently_dropped( load_in_4bit, load_in_8bit, full_finetuning, + quantization_config = None, ): """Guardrail for unslothai/unsloth#5344. @@ -159,6 +158,13 @@ def _warn_if_quantization_silently_dropped( """ if full_finetuning: return + if quantization_config is not None: + if isinstance(quantization_config, dict): + load_in_4bit = load_in_4bit or bool(quantization_config.get("load_in_4bit")) + load_in_8bit = load_in_8bit or bool(quantization_config.get("load_in_8bit")) + else: + load_in_4bit = load_in_4bit or bool(getattr(quantization_config, "load_in_4bit", False)) + load_in_8bit = load_in_8bit or bool(getattr(quantization_config, "load_in_8bit", False)) if not (load_in_4bit or load_in_8bit): return @@ -167,9 +173,10 @@ def _warn_if_quantization_silently_dropped( # Failure mode 1: total bypass. if not has_bnb: kind = "4bit" if load_in_4bit else "8bit" + bnb_class_name = "Linear4bit" if load_in_4bit else "Linear8bitLt" warnings.warn( f"Unsloth: load_in_{kind}=True was requested but no bitsandbytes " - f"Linear{kind} modules were produced.

The adjacent guardrail already normalises load_in_4bit from quantization_config; the swap gate now does the same and sources bnb_4bit_compute_dtype from quantization_config when no local bnb_config is built. The except branch around the swap also previously stated "Falling back to BF16 experts", which misrepresents the model state when the helper fails partway through (already-swapped Gemma4TextExperts modules stay in 4-bit; only the remainder remain BF16). The warning now counts the modules marked _unsloth_gemma4_moe_4bit_swapped and reports the partial state, advising a reload to recover a uniform state. The comment above the fused-Parameter dels in gemma4_moe_4bit.py overstated the swap's memory bound; rephrased to describe the actual per-module peak (fused BF16 plus accumulated per-expert nf4). --- unsloth/models/gemma4_moe_4bit.py | 5 ++-- unsloth/models/vision.py | 41 +++++++++++++++++++++++++------ 2 files changed, 36 insertions(+), 10 deletions(-) diff --git a/unsloth/models/gemma4_moe_4bit.py b/unsloth/models/gemma4_moe_4bit.py index 0863fa477c..5bc724a34b 100644 --- a/unsloth/models/gemma4_moe_4bit.py +++ b/unsloth/models/gemma4_moe_4bit.py @@ -193,8 +193,9 @@ def swap_gemma4_experts_to_per_expert_linear4bit( gate_up_list.append(gu.to(device)) down_list.append(dp.to(device)) - # Drop the fused Parameters before attaching the ModuleLists so peak - # VRAM during the swap stays bounded by one expert at a time. + # The fused BF16 gate_up_proj / down_proj stay live through the loop + # above; per-module peak is fused BF16 + accumulated per-expert nf4. + # They are released here, before attaching the ModuleLists. del module.gate_up_proj del module.down_proj diff --git a/unsloth/models/vision.py b/unsloth/models/vision.py index c3cf98bab8..69eed9743b 100644 --- a/unsloth/models/vision.py +++ b/unsloth/models/vision.py @@ -1071,7 +1071,18 @@ class FastBaseModel: # Opt-in per-expert Linear4bit swap for Gemma-4 MoE checkpoints # whose fused 3D expert weights bnb cannot quantize (#5344). # Off by default; users enable via UNSLOTH_GEMMA4_MOE_4BIT=1. - if load_in_4bit and not full_finetuning: + _user_qcfg = kwargs.get("quantization_config", None) + if isinstance(_user_qcfg, dict): + _qcfg_4bit = bool(_user_qcfg.get("load_in_4bit", False)) + _qcfg_dtype = _user_qcfg.get("bnb_4bit_compute_dtype", None) + elif _user_qcfg is not None: + _qcfg_4bit = bool(getattr(_user_qcfg, "load_in_4bit", False)) + _qcfg_dtype = getattr(_user_qcfg, "bnb_4bit_compute_dtype", None) + else: + _qcfg_4bit = False + _qcfg_dtype = None + _effective_load_in_4bit = bool(load_in_4bit) or _qcfg_4bit + if _effective_load_in_4bit and not full_finetuning: try: from unsloth.models.gemma4_moe_4bit import ( is_gemma4_moe_4bit_enabled, @@ -1079,13 +1090,15 @@ class FastBaseModel: ) if is_gemma4_moe_4bit_enabled(): + if bnb_config is not None: + _compute_dtype = bnb_config.bnb_4bit_compute_dtype + elif _qcfg_dtype is not None: + _compute_dtype = _qcfg_dtype + else: + _compute_dtype = torch.bfloat16 _swapped = swap_gemma4_experts_to_per_expert_linear4bit( model, - compute_dtype = ( - bnb_config.bnb_4bit_compute_dtype - if bnb_config is not None - else torch.bfloat16 - ), + compute_dtype = _compute_dtype, ) if _swapped > 0: print( @@ -1095,10 +1108,22 @@ class FastBaseModel: f"https://github.com/unslothai/unsloth/issues/5344)." ) except Exception as _e: + _partial = sum( + 1 for _m in model.modules() + if getattr(_m, "_unsloth_gemma4_moe_4bit_swapped", False) + ) + if _partial: + _state = ( + f"{_partial} Gemma4TextExperts module(s) are " + f"already in 4-bit; remaining modules stay BF16.

A raw string would propagate to bnb.nn.Linear4bit and crash the first forward with "Invalid device string: 'bfloat16'". - Forward bnb_4bit_quant_type from the user's BitsAndBytesConfig or dict config into swap_gemma4_experts_to_per_expert_linear4bit so swapped experts match the quantization type used by the rest of the model (previously always nf4 even when the caller requested fp4). - Wrap the swap and its warning into a local closure and invoke it from both the regular auto_model.from_pretrained branch and the fast_inference=True / convert_vllm_to_huggingface branch. The closure is idempotent on non-Gemma-4 models, so the vLLM call is free when the loaded model has no Gemma4TextExperts modules. - Escalate partial-state swap failures: if the helper raises after one or more Gemma4TextExperts modules were already committed to 4-bit, the wrapper re-raises a RuntimeError instructing the caller to reload the model. Previously a warning implied a clean BF16 fallback, which is false when partial conversion has already occurred. The closure is multi-line (long block) because it needs to capture the already-resolved quantization parameters and be reusable across both load paths; the alternative is duplicating the entire block. --- unsloth/models/vision.py | 130 ++++++++++++++++++++++----------------- 1 file changed, 75 insertions(+), 55 deletions(-) diff --git a/unsloth/models/vision.py b/unsloth/models/vision.py index 69eed9743b..7d338630a4 100644 --- a/unsloth/models/vision.py +++ b/unsloth/models/vision.py @@ -1044,6 +1044,79 @@ class FastBaseModel: verify_fp8_support_if_applicable(model_config) + # Resolve 4-bit + Gemma4 swap parameters once (shared by both load paths). + _user_qcfg = kwargs.get("quantization_config", None) + if isinstance(_user_qcfg, dict): + _qcfg_4bit = bool(_user_qcfg.get("load_in_4bit", False)) + _qcfg_dtype = _user_qcfg.get("bnb_4bit_compute_dtype", None) + _qcfg_quant_type = _user_qcfg.get("bnb_4bit_quant_type", None) + elif _user_qcfg is not None: + _qcfg_4bit = bool(getattr(_user_qcfg, "load_in_4bit", False)) + _qcfg_dtype = getattr(_user_qcfg, "bnb_4bit_compute_dtype", None) + _qcfg_quant_type = getattr(_user_qcfg, "bnb_4bit_quant_type", None) + else: + _qcfg_4bit = False + _qcfg_dtype = None + _qcfg_quant_type = None + if isinstance(_qcfg_dtype, str): + _qcfg_dtype_str = _qcfg_dtype.removeprefix("torch.") + _maybe_dtype = getattr(torch, _qcfg_dtype_str, None) + _qcfg_dtype = _maybe_dtype if isinstance(_maybe_dtype, torch.dtype) else None + _effective_load_in_4bit = bool(load_in_4bit) or _qcfg_4bit + + def _maybe_swap_gemma4_moe_4bit(_target_model): + if not (_effective_load_in_4bit and not full_finetuning): + return + try: + from unsloth.models.gemma4_moe_4bit import ( + is_gemma4_moe_4bit_enabled, + swap_gemma4_experts_to_per_expert_linear4bit, + ) + + if not is_gemma4_moe_4bit_enabled(): + return + if bnb_config is not None: + _compute_dtype = bnb_config.bnb_4bit_compute_dtype + _quant_type = getattr(bnb_config, "bnb_4bit_quant_type", "nf4") + else: + _compute_dtype = ( + _qcfg_dtype if _qcfg_dtype is not None else torch.bfloat16 + ) + _quant_type = ( + _qcfg_quant_type if _qcfg_quant_type is not None else "nf4" + ) + _swapped = swap_gemma4_experts_to_per_expert_linear4bit( + _target_model, + compute_dtype = _compute_dtype, + quant_type = _quant_type, + ) + if _swapped > 0: + print( + f"Unsloth: swapped {_swapped} " + f"Gemma4TextExperts module(s) to per-expert " + f"Linear4bit (see " + f"https://github.com/unslothai/unsloth/issues/5344)." + ) + except Exception as _e: + _partial = sum( + 1 for _m in _target_model.modules() + if getattr(_m, "_unsloth_gemma4_moe_4bit_swapped", False) + ) + if _partial: + raise RuntimeError( + f"Unsloth: Gemma-4 MoE 4-bit swap failed after " + f"converting {_partial} module(s); model is in a " + f"mixed 4-bit/BF16 state.

Closes ~half the speed gap between the 4-bit loop forward and the BF16 grouped_mm path by skipping dequantization of inactive experts. Three new forward variants, all gated by env vars on top of the existing UNSLOTH_GEMMA4_MOE_4BIT_GROUPED=1: 1. UNSLOTH_GEMMA4_MOE_4BIT_GROUPED_ACTIVE_ONLY=1 Dequant only the experts touched by the current batch's top-k routing instead of all num_experts. Uses torch.unique(top_k_index) for the active set and remaps top_k_index from [0, num_experts) to [0, E_active). Bench on gemma-4-26B-A4B-it shows 2.71-3.01 tok/s vs the loop forward's 1.59 tok/s (~1.7-2.0x speedup), same VRAM (14.27 GB resident, +0.4 GB peak), logits cos_sim 0.998 vs loop. Bit-exact on the synthetic stub. 2. UNSLOTH_GEMMA4_MOE_4BIT_GROUPED_CACHE=1 (requires _ACTIVE_ONLY=1) Per-module LRU of dequantized BF16 experts. Capped at UNSLOTH_GEMMA4_MOE_4BIT_CACHE_SIZE (default 8). Empirically break-even with active-only on the 26B-A4B bench because the torch.stack-into-compact-tensor cost remains; the cache only skips the dequant math. 3. UNSLOTH_GEMMA4_MOE_4BIT_GROUPED_STATIC_BF16=1 Speed-ceiling experiment: dequant every expert ONCE on first forward, keep fused BF16 tensors live for the rest of the module's lifetime. Reaches 5.98 tok/s on 26B-A4B (within 6% of BF16 baseline 6.34) at the cost of peak forward VRAM 57 GB (the 4-bit storage is still resident, so net is BF16 + 4-bit cohabit). Proves per-forward dequant is the bottleneck; the remaining ~2x gap cannot be closed without persistent fused weights or a custom 4-bit grouped GEMM kernel. UNSLOTH_GEMMA4_MOE_4BIT_GROUPED_COMPILE=1 also included as a negative result: torch.compile on the dequant helper regresses to 1.03 tok/s because bnb.functional.dequantize_4bit is a custom CUDA op (graph break) and Inductor can't fuse around it. Forward selection ladder in swap_gemma4_experts_to_per_expert_linear4bit: STATIC_BF16 > ACTIVE_ONLY+CACHE > ACTIVE_ONLY > GROUPED > loop. The env vars are mutually compatible; later flags layer on earlier ones. Unit equivalence tests in temp/sim_5344_{active_only,cached,static_bf16}_unit.py confirm bit-exactness (cos=1.0, max_abs_diff=0) on a synthetic Gemma4TextExperts stub. Real-model bench in temp/sim_5344_grouped_4bit_bench.py with selectable BENCH_MODES.

Implementation: - Pre-compute the dequantized per-block absmax (bnb's nested-blockwise scheme) once at swap time and cache on each Linear4bit as _unsloth_pt_absmax_fp32. Removes bnb from the per-forward path entirely. - Per-forward: nibble unpack + 16-entry NF4 codebook lookup + per-block absmax multiply + reshape to (out, in). All pure tensor ops. - The dequant+stack helper is wrapped in torch.compile so Inductor can fuse with the surrounding stack and grouped_mm. Numerical parity probe (temp/sim_5344_pt_nf4_probe.py) matches bnb bit-exactly on a synthetic stub (cos=1.0, max_abs_diff=0). Real-model swapped forward gives cos 0.996 vs BF16 baseline (vs active-only's 0.985) because the FP32 intermediate multiply is closer to ideal BF16 weights. Speed result on gemma-4-26B-A4B-it (B200): 2.17 tok/s vs active-only's 2.21 tok/s. Essentially break-even. Inductor's fusion across the per-expert iteration in the torch.stack list comprehension is bounded; the real bottleneck (per-expert dispatch + stack copy) survives the compile pass. Resident VRAM +1.33 GB for the cached FP32 absmax buffers. Kept in the codebase as a negative result + foundation for a future vectorised-across-experts dequant pass, which would stack packed uint8 and absmax into (E_active, ...) tensors BEFORE the dequant so Inductor sees a single batched op.
