Every model constructor passed the constructor parameter (args/config) to model_(...) instead of the member config_. Since the parameter is a const reference to a local variable in load_typed_model(), it becomes a dangling reference after that function returns. The inner model's Attention layer stores this reference and later reads zeroed/freed stack memory, causing integer division by zero in resolved_head_dim() (hidden_size / num_attention_heads where num_attention_heads reads as 0). This manifested as SIGFPE (exit code 136) on the very first forward pass, before any GPU work. The crash was incorrectly attributed to GPU kernel floating-point exceptions. Fix: pass config_ (the persistent member copy) instead of the constructor parameter. Safe because config_ is always declared before model_ in every affected class. Tested on: - AMD Radeon RX 9070 XT (gfx1201) — 290 tok/s - AMD Ryzen AI MAX+ 395 gfx1151 — 111 tok/s
Port of mlx-community/bitnet-b1.58-2B-4T model to the post-PR#39 codebase.
Architecture (Llama variant with 3 differences):
- relu_squared activation instead of silu
- Sub-layer norms: attn_sub_norm before o_proj, ffn_sub_norm before down_proj
- Ternary weights {-1,0,+1} packed as uint8 (4 values/byte), dequantized at load
Dequantization: concatenate 4 bit-lanes along axis 0 (not stack+reshape)
to match the transformers/BitNet reference unpacking order.
Files:
- include/mlx-lm/llm/models/bitnet.h — model header (BitNetAttention, BitNetMLP,
BitNetTransformerBlock, BitNetModelInner, BitNetModel)
- src/llm/models/bitnet.cpp — implementation with ternary dequant, relu², sub-norms
- src/llm/llm_factory.cpp — factory registration (loader + type registry)
- CMakeLists.txt — source file added
Config reuses LlamaConfiguration (identical fields).
No dangling reference: BitNetModel stores config_ as value, passes config_
(not constructor param) to model_.
Tested on gfx1151 (Radeon 8060S): 'The capital of France is' → 'Paris...'
Coherent, correct output.
Closes lemonade-sdk#2
Closes lemonade-sdk#12
Code review (PR lemonade-sdk#41) noted the parameter was unused. Kept it in the signature for API clarity (documents the expected output row count) but marked it unused to suppress warnings.
Three changes to close all gaps from issue lemonade-sdk#2: 1. Falcon-E 3B support (model_type=bitnet, hidden_act=silu): - Add hidden_act field to LlamaConfiguration - Make BitNetModel adaptive: uses relu²+sub_norms only when hidden_act=relu2, falls back to silu+no sub_norms for Falcon-E-style models - Add load_bitnet_model/create_bitnet_model dispatchers in factory that route to LlamaModel when hidden_act!=relu2 (LlamaModel already has BitNet ternary dequant in its sanitize_impl) - Extract dequantize_bitnet_weight to shared bitnet_utils.h header 2. Bonsai 1-bit affine support (issue lemonade-sdk#11, bits=1): - Add dequantize_1bit() in quantize_utils.cpp — extracts 32 1-bit values per uint32 using bitwise ops, applies per-group scale+bias - Route bits==1 weights through load-time dequant (like embeddings) since MLX GPU affine_dequantize kernel doesn't support 1-bit - Formula matches MLX's affine_dequantize: value = bit * scale + bias 3. Bonsai YaRN rope scaling: - Qwen3Attention now handles rope_type=yarn (previously only linear) - Treated as 1/factor scaling (sufficient for short-medium context) Verified on gfx1151 (Strix Halo): - BitNet b1.58-2B-4T: 'Paris, and it is known for its iconic landmarks...' - Bonsai 1.7B: 'Paris, which is the capital of the country' - Bonsai 4B: 'Tokyo, the capital of Japan' - Llama 3.2 1B: 'Paris. The capital of Germany is Berlin...' (no regression) - Falcon-E 3B: loads and runs (model itself is broken — HF transformers also produces garbage with this quantized checkpoint; original unquantized works) Closes lemonade-sdk#2, lemonade-sdk#11
When a BitNet config omits hidden_act, the LlamaConfiguration struct defaults to 'silu', but the dispatcher defaults to 'relu2'. This inconsistency would cause BitNetModel to use silu instead of relu². Fix by injecting hidden_act='relu2' into the config JSON before constructing BitNetModel when the key is missing.
Issue lemonade-sdk#9: rocBLAS error: Could not initialize Tensile host Two changes: 1. Auto-configure ROCm Tensile library paths (examples/chat.cpp): - Auto-detects ROCBLAS_TENSILE_LIBPATH and HIPBLASLT_TENSILE_LIBPATH - Searches common locations: /opt/rocm, TheRock venv, library-relative - Only sets if not already set by user (setenv overwrite=0) - Runs before any MLX device initialization - Fixes the 'Could not initialize Tensile host' error when rocBLAS can't find its TensileLibrary kernel files 2. Fix lille-130m weight key prefix (src/llm/models/lille130m.cpp): - Weight keys in safetensors use 'transformer.' prefix - weight_map() was returning keys without the prefix (bug in original code) - Fixed to add 'transformer.' prefix in weight_map() - Added quant_bits/quant_group_size to Lille130mConfiguration - sanitize_impl now dequantizes all weights at load time using config values - Bypasses quantized_matmul for this small 130M model The Tensile fix addresses the environment issue from issue lemonade-sdk#9. The lille-130m weight prefix fix addresses the model-specific garbage output. The lille model still produces low-quality output (repetitive) which appears to be an architecture-level issue requiring further investigation.
Issue lemonade-sdk#7: Segmentation fault near hipblaslt with OpenELM The C++ OpenELM port had three bugs: 1. Ignored explicit num_query_heads/num_kv_heads from config.json - Recomputed them from qkv_multipliers range [0.5, 1.0] via stride - But the MLX-converted model config provides explicit per-layer arrays - The computed values mismatched the actual weight shapes for many layers - This caused wrong qkv_proj/out_proj dimensions → NaN logits → segfault - Fix: Read explicit num_query_heads/num_kv_heads when present in config 2. Ignored explicit ffn_multipliers (36-element array) from config.json - Treated it as a 2-element [start, end] range and computed via stride - But the config provides a full 36-element per-layer list - Fix: Use the full list directly when size matches num_layers 3. lm_head_weight_ initialized with wrong shape - Used {vocab_size, num_transformer_layers} instead of {vocab_size, model_dim} - Fix: Use {vocab_size, model_dim} Also added rope_freq_constant as an alias for rope_theta (the config uses rope_freq_constant, not rope_theta). The segfault is fixed — the model now loads and runs without crashing. Output quality still needs BOS token prepending (OpenELM is a base model).
Issues lemonade-sdk#5, lemonade-sdk#8: Many models used mx::matmul(x, mx::transpose(weight)) directly for the lm_head and tied embeddings (embed_as_linear), bypassing the QuantizedWeightRegistry. When weights are quantized (4-bit, 8-bit), this causes shape mismatches (packed weight shape vs expected full shape) and garbage/zero output. Fixed 62 occurrences across 39 model files by replacing: mx::matmul(x, mx::transpose(weight)) with: linear_forward(x, weight) linear_forward checks the QuantizedWeightRegistry and uses mx::quantized_matmul when the weight is quantized, falling back to regular mx::matmul otherwise. This fixes: - Issue lemonade-sdk#5: GLM-Z1-32B-4bit matmul shape mismatch (lm_head was quantized) - Issue lemonade-sdk#8: Qwen3-Next-80B zero logits (lm_head was quantized) - Any model with quantized tied embeddings or quantized lm_head Affected models: glm4, glm4_moe, glm4_moe_lite, deepseek_v3, qwen2, qwen3, qwen3_moe, qwen35, qwen35_moe, qwen3_next, llama, olmo2, olmo3, olmoe, mimo, apertus, mistral3, lfm2, lfm2_moe, gemma, gemma2, gemma3_text, gemma3n_text, granite, granite_moe_hybrid, phi3, starcoder2, jamba, gptoss, afmoe, bailing_moe, minicpm, ernie4_5, baichuan_m1, exaone4, smollm3, cohere, lille130m, openelm, bitnet Verified: Llama-3.2-1B-4bit, BitNet-2B, Bonsai-1.7B all still produce correct output after the change.
Issue lemonade-sdk#10: [gather_qmm] Biases must be provided for affine quantization The error occurred with MXFP4-quantized models (e.g. gpt-oss-120b-mxfp4, Qwen3-1.7B-MXFP4). MXFP4 mode does not use biases, but the code was: 1. base_config.h: Hardcoded QuantizationMode::Affine, never parsed 'mxfp4' from config.json's quantization.mode field 2. base_config.cpp: 'mode' was in skip_keys, never read into Quantization 3. quantize_utils.cpp: Always passed mode='affine' to quantized_matmul/ gather_qmm, which requires biases for affine mode 4. quantized_linear.h: QuantizationInfo had no mode field; linear_forward always used mode='affine' 5. switch_layers.cpp: SwitchLinear always passed mode='affine' to gather_qmm Fix: - Added QuantizationMode::Mxfp4 enum value - Parse 'mode' from config.json quantization config (base_config.cpp) - Added mode field to QuantizationInfo (quantized_linear.h) - Thread mode through register_weight, linear_forward, SwitchLinear - For MXFP4: dequantize at load time using mx::dequantize(w, scales, nullopt, group_size, bits, 'mxfp4') — the ROCm quantized_matmul/ gather_qmm backends don't support MXFP4 mode natively (only Affine), so we dequantize to dense bf16 at load time - MXFP4 dequantization uses MLX's fp_dequantize kernel (supported on ROCm) Verified: Qwen3-1.7B-MXFP4 loads and generates tokens without crash. Output quality is limited (base model without chat template/BOS), but the original 'Biases must be provided' crash is resolved. Also fixes: OpenELM segfault (issue lemonade-sdk#7) — explicit num_query_heads from config, and the systemic linear_forward fix (issue lemonade-sdk#5) for quantized lm_head/embed_as_linear across 39 model files.
- Patch minja::Context::builtins() to register 'capitalize' as a
global filter, fixing BitNet chat template rendering that uses

…aph skip for quantized ops - Replace load-time dequantization to fp16 with direct repack to standard MLX uint32 2-bit quantized format in sanitize_impl - Register weights in QuantizedWeightRegistry with group_size=128, bits=2, bias=-scale so the affine dequant formula reproduces exact ternary values - GPU memory drops from 4.6 GB → 2.7 GB (41% reduction) - Decode speed improves from 8.1 → 32.4 t/s (4x faster on gfx1151) - Add patches/mlx-rocm-skip-graph.patch: skip_graph flag avoids batching QuantizedMatmul's tiny tiled kernels into HIP graphs - CMakeLists.txt: apply patch after fetching MLX dependency - Update benchmark_all.sh
- Move bitnet_repack_weights to bitnet_utils.h for reuse in tests - Add test_bitnet_quant.cpp: 9 test cases, 23 assertions for 2-bit quant - Add benchmark_tb5.sh: comprehensive TB5 + R9700 benchmark script - SkipGraphGuard in eval.cpp: exception-safe reset of skip_graph flag - Update patches/mlx-rocm-skip-graph.patch with all ROCm backend changes - Add test_bitnet_quant to tests/CMakeLists.txt
- Runtime quantized matmul produces wrong results on 2-bit with bias=-scale (verified: registry hits, correct shapes, correct scale values, test passes but full model output is garbage). Root cause: 2-bit QMV kernel precision issue with per-channel bias. Falls back to dequantize-at-load for now. - bitnet_repack_weights ready in bitnet_utils.h for when kernel is fixed - Pin mlx-src to commit 6abf0b7e (working ExecUpdate graph, not broken pure-relaunch) - Build config: gfx1151 only, -parallel-jobs=16 patched out - Remove debug prints from quantized_linear.h
- Verified: standard 2-bit affine quantization (bias=-scale) is architecturally
correct for representing ternary {-1,0,+1} values from codes {0,1,2}
- Verified: repack function, registry registration, shapes, and scale values all correct
- Root cause: 2-bit QMV kernel produces wrong results with bias=-scale on this system
despite the unit test passing (test uses small shapes that may hit different code paths)
- 4-bit requantization loses precision (cannot represent exact three levels)
- Falls back to dequantize-at-load fp16 path for correctness
- bitnet_repack_weights() ready in bitnet_utils.h for when kernel fix lands
- CMakeLists.txt pins mlx-src to working commit 6abf0b7e
- Re-enable BitNet runtime 2-bit quantized matmul now that repack preserves the model's lane-major output layout - Register BitNet weights with group_size=128, bits=2, affine bias=-scale - Add regression tests for lane-major repack, registry/linear_forward wiring, and real BitNet decode shape (M=1, N=2560, K=2560) - Replace broken skip-graph patch with ROCm build patch that removes unsupported -parallel-jobs from MLX HIP custom commands - Apply MLX patch before add_subdirectory so fresh source builds need no sed
- Parse BitNet quantization_config to distinguish direct autobitlinear scales from inverse BitLinear weight_scale semantics - Route model_type=bitnet through BitNetModel for both relu2 BitNet and silu Falcon-E so runtime 2-bit matmul is used instead of fp16 dequant fallback - Add inverse-scale dequant/repack support and regression tests - Update benchmark label: Falcon-E is no longer a broken checkpoint
Phase 1 — Universal download (hub_api.cpp): - Replace hardcoded file list with HF API file enumeration - Download all *.json/*.safetensors/*.model/*.txt/*.jinja files present in repo - Fall back to hardcoded list on API failure (no regression) Phase 2 — Universal tokenizer (tokenizer.cpp): - Add tokenizer.model (SentencePiece) fallback - Add vocab.json + merges.txt (GPT BPE) fallback - Continue if one tokenizer format fails, try next Phase 3 — Weight loading robustness (llm_factory.cpp): - Warn on missing weight keys (catches HF naming mismatches) - List supported model types when model_type is unknown - Add common HF architecture aliases Co-authored-by n/a
- Important-1/2: hub_api snapshot_download now logs per-file download errors and gates the cache shortcut on config+weights (avoids stale partial-download shortcuts); fatal-throws if weight files fail - Important-3: tokenizer loading in llm_factory now calls Tokenizer::from_directory unconditionally (was gated on tokenizer.json existing, making SentencePiece/BPE fallbacks unreachable). Wrapped in try/catch with diagnostic. - Minor-4: reworded missing-weight warning (left unset, not zero-filled) - Minor-6: skip pytorch_model/flax_model/tf_model index/metadata files
- On-the-fly auto-quantization: --auto-quantize flag in chat loads
unquantized bf16/fp16 models and quantizes to 4-bit at load time.
Each 2D float weight is quantized via mx::quantize(group_size=64,
bits=4) and registered in QuantizedWeightRegistry.
- quantization_config reading: parse_base_configuration now reads
HF-standard quantization_config (group_size, bits, mode) alongside
existing MLX quantization field.
- GGUF skeleton: gguf_loader.{h,cpp} with is_gguf_file() detection,
gguf_config_from_metadata() config synthesis, and load_gguf_weights()
with GGUF-to-HF tensor name remapping (blk.{N}.* pattern).
Integration into main load path deferred (needs model_manager routing).
- Build clean, all tests pass, all 3 regression models verified.
- GGUF load path integrated into load_llm_from_directory: detects .gguf files, synthesizes config.json from metadata, loads/remaps weights - GGUF direct file support: if model_id is a .gguf file, wraps in parent dir and routes through GGUF loader - Auto-quantize verified: --auto-quantize flag quantizes bf16 weights to 4-bit. Test: auto_quantize_weights correctly converts a bf16 [4,128] weight to uint32 packed format and registers in registry. - Full regression (38 assertions, 16 test cases): all pass. - BitNet-2B, Falcon-E-3B, Llama-1B: all still correct.
- ModelManager: added set_auto_quantize(bool) and auto_quantize_ member - model_manager get_or_load passes auto_quantize to load_llm and load_mtp_delta_model - server: --auto-quantize flag added, passed through to ModelManager and load_llm for both pre-load and auto-load paths - load_mtp_delta_model: accepts auto_quantize bool, passes through to auto_quantize_weights at load time - MTP delta detection in load_llm_from_directory passes config.auto_quantize
- Server: --auto-quantize flag added to both CLI and ModelManager, passed through to load_llm and load_mtp_delta_model for pre-load and auto-load paths - ModelManager: set_auto_quantize(bool) + auto_quantize_ member - load_mtp_delta_model: accepts bool auto_quantize, calls auto_quantize_weights at load time - Generic HF weight-key remapping: before warning on missing keys, tries common alternative naming conventions (double model. prefix, transformer./gpt_neox./llama. prefixes, missing model. prefix) - Verified: SmolLM-135M from HF fresh download (134 MB, 292 tok/s) - Verified: Bonsai-1.7B 1-bit model from HF cache (3.3 GB, 37.5 tok/s)
Engine now reads GGUF files DIRECTLY (no MLX loader dependency):
- Full GGUF format parser: header, metadata, tensor info, tensor data
- Dequantizers for ALL common formats:
* Float: F32, F16, BF16 (pass-through)
* Simple block: Q4_0, Q4_1, Q5_0, Q5_1, Q8_0, Q8_1
* K-quants: Q2_K, Q3_K, Q4_K, Q5_K, Q6_K
- Each quant format is dequantized to fp16 at load time
- GGUF tensor name remapping (blk.{N}.* -> HF naming)
- Replaces limited MLX GGUF loader entirely
- Independent function: gguf_read_metadata() for config synthesis
When load_safetensors_from_directory finds no .safetensors files, it now checks for pytorch_model.bin (single or sharded). If found, it writes a temp Python script that uses torch + safetensors to convert, executes it via subprocess, then loads the converted safetensors. Handles both single and sharded .bin formats. Falls back to clear error with installation instructions if torch or safetensors are not available.

The NripeshN/mlx fork at the pinned commit 6abf0b7e does not export several GPU primitives that the engine forward-declares in graph_decode.cpp and generate.cpp: - gpu_kv_pos_set / gpu_kv_pos_increment (KV-cache position helpers) - gpu_scalar_copy_i32 / gpu_buffer_copy (GPU buffer ops) - decode_arena_* (Decode arena lifecycle) - decode_pure_record / decode_pure_replay (Pure decode recording) Added src/common/gpu_stubs.cpp with no-op fallback implementations that let the CI ROCm build link cleanly. test_arena.cpp now links mlx-lm-common to share the stubs instead of duplicating them. All 34 test_bitnet_quant tests + 21 test_generate tests pass.

…de-sdk#8) The mx::compile'd T=1 decode fast path for Gated Delta Network layers produces incorrect recurrent state updates on ROCm, causing a repeating 2-token output pattern (ᑋ/okino). The compiled kernels capture stale state references that don't update correctly across decode steps. Fix: Disable the T=1 fast path by guarding with (false && ...), forcing all decode steps through the general (non-compiled) path which uses gated_delta_update() directly with correct state management. Note: Issue lemonade-sdk#6 (Granite MoeHybrid crash) requires an upstream fix in the NripeshN/mlx ROCm backend - the hipLaunchKernel symbol lookup for strided_scan<float, Sum> fails because weak __device_stub__ symbols from static libraries are not found by the HIP runtime. Workaround: compile with -fgpu-rdc and ensure whole-archive linking of the kernel library.
Issue lemonade-sdk#6: Granite MoeHybrid model crashes on ROCm because hipLaunchKernel cannot find strided_scan<float, Sum, ...> kernel. The device code exists in the static library but weak __device_stub__ symbols are dropped during linking. Fixes attempted: - --whole-archive: pulls in distributed.hip with unsatisfied deps - Adding -u flags: doesn't retain weak symbols - __attribute__((used)): no effect on HIP weak symbols - -fgpu-rdc: generates __hip_gpubin_handle symbols not available to non-hipcc linker - Separate .hip stub file: symbol still dropped Root cause: MLX ROCm backend uses add_kernel_node() which passes function pointers to hipLaunchKernel. The HIP runtime resolves these through fat binary registration, but the linker doesn't retain the weak __device_stub__ for float32 Sum strided_scan. Fix needed upstream in NripeshN/mlx: switch scan operations to use add_module_kernel_node() with JIT-compiled kernels (like other backends) which doesn't require pre-linked device symbols. Also fix: Qwen3Next disable T=1 compiled decode fast path on ROCm (lemonade-sdk#8)
Issue lemonade-sdk#6 (Granite MoeHybrid) root cause confirmed: hipLaunchKernel function pointer lookup for strided_scan<float, Sum, ...> fails on ROCm 7.2.4 because the HIP runtime cannot resolve weak __device_stub__ symbols from static libraries even when present in the binary. All approaches exhausted: - --whole-archive: pulls in distributed deps - -u flags: doesn't retain weak symbols - __attribute__((used)): no effect on HIP weak symbols - -fgpu-rdc: generates __hip_gpubin_handle symbols (needs hipcc link) - Standalone .hip compiled with hipcc: symbol still unresolvable Fix requires upstream MLX change: use add_module_kernel_node (JIT) instead of add_kernel_node (fat binary) for float32 scan ops, or adopt -fgpu-rdc + hipcc link step in the ROCm CMake build.
