* Updated binaries, using [this build](https://github.com/SciSharp/LLamaSharp/actions/runs/8654672719/job/23733195669) for llama.cpp commit `f7001ccc5aa359fcf41bba19d1c99c3d25c9bcc7`.
- Added all new functions.
- Moved some functions (e.g. `SafeLlamaModelHandle` specific functions) into `SafeLlamaModelHandle.cs`
- Exposed tokens on `SafeLlamaModelHandle` and `LLamaWeights` through a `Tokens` property. As new special tokens are added in the future they can be added here.
- Changed all token properties to return nullable tokens, to handle some models not having some tokens.
- Fixed `DefaultSamplingPipeline` to handle no newline token in some models.
* Moved native methods to more specific locations.
- Context specific things have been moved into `SafeLLamaContextHandle.cs` and made private - they're exposed through C# properties and methods already.
- Checking that GPU layer count is zero if GPU offload is not supported.
- Moved methods for creating default structs (`llama_model_quantize_default_params` and `llama_context_default_params`) into relevant structs.
* Removed exception if `GpuLayerCount > 0` when GPU is not supported.
* - Added low level wrapper methods for new per-sequence state load/save in `SafeLLamaContextHandle`
- Added high level wrapper methods (save/load with `State` object or memory mapped file) in `LLamaContext`
- Moved native methods for per-sequence state load/save into `SafeLLamaContextHandle`
* Added update and defrag methods for KV cache in `SafeLLamaContextHandle`
* Updated submodule to `f7001ccc5aa359fcf41bba19d1c99c3d25c9bcc7`
* Passing the sequence ID when saving a single sequence state
- Properly displaying `LLamaToken`
- Removed all tokenisation code in `SafeLLamaContextHandle` - just pass it all through to the `SafeLlamaModelHandle`
- Improved `SafeLlamaModelHandle` tokenisation:
- Renting an array, for one less allocation
- Not using `&tokens[0]` to take a pointer to an array, this is redundant and doesn't work on empty arrays
- made `llama_backend_init` private. This is automatically called, there is no way it can correctly be used externally.
- made `llama_token_to_piece` safe (Span instead of pointer)
- Made `NativeApi` into a `static class` (it's not intended to be instantiated)
- Moved `LLamaTokenType` enum out into a separate file
- Made `LLamaSeqId` and `LLamaPos` into `record struct`, convenient to have equality etc
- `AntipromptProcessor` accepts chunks of text and returns a value indicating if any antiprompt has been detected.
- `StreamingTokenDecoder` decodes tokens into text, maintaining some internal state to handle single characters which are encoded as multiple tokens.
Added tests for these classes and updated StatelessExecutor to use them.
Removed most DeTokenize methods, marked the rest as obsolete (should always use a `StreamingTokenDecoder`).
- Minimal amount of characters converted
- Allocation free
- Added `TokensToSpan` to `SafeLlamaModelHandle` which converts as many tokens as possible into a character span
- Allocation free
- Just convert it to a `string`, nice and simple
- Write the bytes to a `Span<byte>` no allocations
- Write the chars to a `StringBuilder` potentially no allocations
This change _only_ implements the low level API and makes no effort to update the LlamaSharp higher level abstraction.
It is built upon llama `b3f138d`, necessary DLLs are **not** included in this commit.
