Must not pass image tokens to the EmbedMMToken used for text.
Caught by next presubmit test.
paligemma_test: move function bodies into class, regroup variables
PiperOrigin-RevId: 770040014
Parallelize over queries instead of tokens
introduce non_eos so we only iterate over not yet EOS queries; remove TokenStreamer.
move RMSNormInplaceBatched out of Transformer to call the latter from prefill
Consistent arg order.
Fix gemma_test EOS handling which (caught by msan), remove from tokenizer.h
Also add output to gemma_batch_bench, fix name
PiperOrigin-RevId: 769676106
BF16 att_sums and ffw_out
Support BF16 B views without decompression
Support arbitrary types in MulByConstAndAdd, AddFrom
Also update profiler annotations in ops-inl.h
PiperOrigin-RevId: 766995010
Detect PaliGemma models from layer names
Remove unused allocator arg from CreateInvTimescale
matmul: only warn once about dim divisibility
Print config also in tests if --verbosity 2
PiperOrigin-RevId: 766605131
This replaces per-weight instantiations of all code with only per-MatMul/norm.
Reduces binary size by 133KiB.
WeightsOwner is no longer required for type erasing, hence it is replaced with ModelWeightsPtrs.
Also remove unused EmbedToken, replaced with EmbedMMToken.
PiperOrigin-RevId: 766497657
Precompute row pointers.
Remove no longer used MHA support; QStride -> qkv_dim.
Remove RowPtr from MatMul interface, use only MatPtrT.
Require opt-in define for NUQ to speed up builds.
Also fix io.cc on Windows.
PiperOrigin-RevId: 766228108
Only the weights; binding MatMul output worsens batch=1 prefill.
Update gemma_batch_bench to use --decode_qbatch.
Fix/remove prefill_activations in gemma-inl.h.
Refactor:
use BasePageBytes directly when binding
Move BindB/C to .cc by de-templatizing
Remove MatOwners::AllocateFor because it is weights-specific (binding or not)
Disband MatOwners, replace with vector
PiperOrigin-RevId: 759610477
Remove kOnlyAllocate - no longer used. Rename ReadOrAllocate -> ReadFromBlobs.
Rename Reshape -> Fixup to reflect the new scope.
Remove no longer used ShrinkRows.
This simplifies gemma-inl and is a prerequisite for removing ConstMat
(whose .ofs was previously used for merged tensors)
PiperOrigin-RevId: 758214083
KVCache: add ctor required for MatStorageT, remove Create; bf_pre_ffw_rms_out -> pre_ffw_rms_out
optimize_test: larger vocab_size requires more steps
shared.h: Remove unused u128 type
correctly set Activation matrix rows, avoid passing as arg
ops: pass Mat instead of pointers/sizes; vectorize LayerNorm; support any weight type
mat: add OverrideRows, used by SetBatchSize
PiperOrigin-RevId: 757790736
Also in this change:
* The computation for a single `q` is factored out and exposed.
* Strided `ConstMat` views into the KV caches are introduced to enable experimentation with various KV cache layouts.

- chore: unused parameters cleaned up
- bugfix: explicitly use hwy::Span in GenerateInternal() to prevent runtime crashes due to memory layout incompatibility
- bugfix: explicit nullptr check in LogDebug
- chore: length-related parameters renamed for clarity
- feature: SaveConversation() can be optionally used to save copy of a conversation that ResetConversation() will rewind to upon request, rather than just an empty KV cache
- feature: GetCurrentConversation() can be used to query the current conversation's name
PiperOrigin-RevId: 755873147
Weight handling:
- new ModelStore2 supports both pre-2025 multi-file and single-file formats
- simpler ForEachTensor with TensorArgs
- tensors are constructed with their full suffixed name
I/O:
- support mmap and stride
- Simplified SbsWriter, single insert(); add SbsReader
Misc:
- kMockTokenizer: allow creating with unavailable tokenizer
- configs.h: Simpler enum validity checks via kSentinel
- matmul.h: remove unused enable_bind (now in allocator.h)
- tensor_info: single TensorInfoRegistry class, rename from tensor_index.h
Frontends:
- Replace Allocate/CreateGemma with ctor(LoaderArgs, MatMulEnv&)
- Deduce model/weight type, remove --model and parsing
- Replace most common.h includes with configs.h
- Remove --compressed_weights, use --weights instead
- Remove ModelInfo, replaced by ModelConfig.
Backprop:
- Reduce max loss, remove backward_scalar_test (timeout)
- Update thresholds because new RandInit changes rng eval order and thus numerics
PiperOrigin-RevId: 755317484
This change adds a basic C API that allows access to Gemma functionality from other programming languages. The functionality is exposed via a shared library (DLL on Windows), with C++ interfaces and a basic C# interop wrapper included.
To build the DLL, use the `windows-dll` preset, which includes the C and C++ sources as follows:
```
cmake --preset windows-dll
cmake --build --config Release --preset windows-dll -j 4
```
This should generate a `gemma.dll` in `<build-dir>/Release`.
To build for non-Windows, the appropriate C++ DLL linking will need to be done to generate a shared library for the target OS.

- Added prompt flag to InferenceArgs for non-interactive mode
- Set user-facing options to verbosity level 1
- Fixed prompt_size declaration and variable ordering in run.cc
- Properly set prompt_size after WrapAndTokenize calls
- Moved kVerboseLogTokens block after prompt_size is set
This change adds a --prompt command-line option that allows users to
provide prompts directly without entering interactive mode, which is
useful for scripting and automation.
