9ee72225dc Function calling support for Kimi-K2 (#628)
* Implement function calling / tools for ik_llama.cpp for Kimi K2

* Implement basic tool choice

* Backport llama.cpp tool calls support

* Enhance function calls with improved chat parser and string utilities

- Add new chat.h/chat.cpp and chat-parser.h/chat-parser.cpp for better chat handling
- Improve function calls parsing with fallback to llama.cpp builder pattern
- Add string utility functions (starts_with, ends_with, find_partial_stop)
- Update README with function calls testing instructions
- Enhance Kimi K2 parser and function calls documentation
- Add comprehensive test suite for function calls
- Update CMakeLists.txt and Makefile for new components

* Enhance function calling with unified streaming and parser improvements

- Fix streaming content cleanup to prevent function syntax in output
- Unify content extraction patterns with llama.cpp approach
- Improve Kimi K2 parser robustness and partial content handling
- Add comprehensive test coverage for function call scenarios
- Optimize chat message parsing and diff computation

* Replace hardcoded values in kimi_k2_parser.hpp with named constants

- Add compile-time constants for all token format markers
- Add compile-time constants for XML format markers
- Add compile-time constants for simple format patterns
- Replace all hardcoded string literals with named constants
- Use compile-time length calculation to avoid manual counting
- Improve maintainability and reduce magic numbers throughout parser

* Fix duplicate common_chat_parse definition

- Remove duplicate implementation from chat-parser.cpp
- Keep single implementation in chat.cpp following llama.cpp patterns
- Resolves linker error: multiple definition of common_chat_parse

* Fix JSON assertion failure in function call parsing

- Add proper validation that 'function' field is an object before accessing nested keys
- Handle missing 'arguments' field gracefully with default "{}"
- Prevents crash when parsing malformed tool call JSON structures

* Add comprehensive Qwen3 XML tool calling support with unit tests

- Implement Qwen3 XML parser with <tool_call>{"name": "func", "arguments": {...}}</tool_call> format
- Add model detection and routing for Qwen3 vs Kimi-K2 formats
- Create 8 comprehensive unit tests covering parsing, streaming, error handling
- Fix token format cleaning bug in kimi_k2_parser.hpp processing order
- Remove progressive parsing code and related utilities
- Add tool injection support for Qwen3 format in server utils

* Add DeepSeek R1 function calling support with comprehensive unit tests

- Implement complete DeepSeek R1 tool call parsing in common_chat_parser.cpp
- Add DeepSeek R1 model detection and tool injection in deepseek_r1_tools.hpp
- Update function_calls.hpp with DeepSeek R1 integration and content extraction
- Update documentation to reflect support for Kimi-K2, Qwen3, and DeepSeek R1 models
- Add comprehensive unit tests for DeepSeek R1 reasoning, tool calls, and integration
- Port exact implementation patterns from original llama.cpp for compatibility

Key features:
- Native DeepSeek R1 format: <|tool▁calls▁begin|>function<|tool▁sep|>name```json{}```<|tool▁call▁end|><|tool▁calls▁end|>
- Reasoning content extraction from <think>...</think> tags
- Multiple tool calls support with separate call blocks
- Model detection for deepseek-r1, deepseek_r1 naming patterns
- Integration with incremental parsing and streaming support

* Add partial parsing support for JSON and regex

- json-partial.h/cpp: JSON partial parsing functionality
- regex-partial.h/cpp: Regex partial parsing functionality

* Add format_chat integration tests for Qwen3 tool injection

- Add test_qwen3_format_chat_integration() to validate tool injection pipeline
- Test tool injection conditions and system message enhancement
- Verify JSON formatting and anti-preamble instructions
- Add comprehensive test documentation

Tests confirm tool injection works correctly - conversational preamble
issue is not in ik_llama.cpp but likely in UI configuration.

* Fix Qwen3 tool call parsing - pass model name to parser

Server was not passing model name to parse_chat_message_incremental(),
causing Qwen3 to fall back to Kimi-K2 parser and return tool calls
as content instead of proper tool_calls array.

* Fix non-streaming path to use model-specific parsing

Non-streaming responses were hardcoded to use Kimi-K2 format,
causing Qwen3 XML tool calls to be returned as content instead
of proper tool_calls array. Now uses same model detection as
streaming path for consistency.

d1ae1504c6 Fix non rpc build error (#506)
* Add RPC backend in device list to override tensors.

* rpc : prevent crashes on invalid input (#9040)

Add more checks which prevent RPC server from crashing if invalid input
is received from client
# Conflicts:
#	ggml/src/ggml-rpc.cpp

* rpc : print error message when failed to connect endpoint (#9042)

* Fix RPC error

* Add vulkan, sycl to rpc backend

* add thread in rpc cpu backend

* add cache folder and other improvement in rpc

* add header file

* support for models with non-512 aligned tensors

* rpc : do not wait for response when sending RPC_CMD_SET_TENSOR (#12943)

RPC_CMD_SET_TENSOR always returns an empty response and we send this 4
times per token. We can improve TG speed if we don't wait for this empty
response.

The performance impact of this change depends on the network latency.
# Conflicts:
#	ggml/src/ggml-rpc.cpp

* fix(rpc): Improve input validation and error handling (#13069)

* fix(rpc): Improve input validation and error handling

The `rpc-server` was vulnerable to Denial of Service attacks via
several RPC commands (`SET_TENSOR`, `GRAPH_COMPUTE`, etc.). Malformed
messages could trigger failed assertions (e.g., invalid `ggml_type`)
or out-of-bounds reads/writes leading to `GGML_ABORT` calls,
crashing the server process.

This PR introduces robust input validation and replaces `abort()`
calls with graceful error handling:

- **Type Validation:** `deserialize_tensor` now checks if the
  `tensor->type` is within the valid `GGML_TYPE_COUNT` range
  *before* calling `ggml_new_tensor_4d`. Returns `nullptr` on
  invalid type.
- **Bounds Checks:** Replaced `GGML_ABORT` in `set_tensor`,
  `set_tensor_hash`, and `get_tensor` handlers with error
  logging and returning `false` when data/offset parameters
  are out of buffer bounds.
- **Size Checks:** Added safe arithmetic checks (for overflow) in
  `graph_compute` when calculating required message sizes based
  on client-provided `n_nodes` and `n_tensors`. Returns early
  if the reported sizes conflict with the actual message size or
  would lead to overflow.
- **Error Propagation:**
    - `create_node` now checks for `nullptr` return values from
      `deserialize_tensor` and its recursive calls, propagating
      `nullptr` upwards on failure. Uses `find` instead of `at`
      for safer map access.
    - `copy_tensor` now checks for `nullptr` from `deserialize_tensor`
      and sets the response status to failure if deserialization
      or bounds checks fail.
    - `graph_compute` now checks for `nullptr` return from
      `create_node` and returns failure status correctly. The final
      return value now reflects the actual computation status.

These changes improve the RPC server's resilience
against malformed client requests, preventing crashes and ensuring
errors are handled more gracefully.

* refactor(rpc): ambiguous nullptr from create_node

rpc_server::create_node could previously return nullptr if the input ID
was 0 (valid) or if an internal error (deserialization, recursion
failure) occurred (invalid). This ambiguity made error handling
difficult for the caller (`graph_compute`).

This commit clarifies the meaning of nullptr:
- `graph_compute` now checks if the input 'id' was non-zero when
  `create_node` returns nullptr, correctly identifying failures
  versus intentional null links.
- `create_node` avoids recursive calls for zero IDs and propagates
  nullptr unambiguously on failure during recursion.

Signed-off-by: Ville Vesilehto <ville@vesilehto.fi>

* refactor(rpc): initial zero check in create_node

The caller (`graph_compute`) already checks `id != 0` when handling
a `nullptr` return from `create_node`, correctly distinguishing
intentional null links from actual errors. This makes the initial
`if (id == 0)` check redundant.

Also removes the log message when a tensor ID is not found in the
provided map which was added in this branch.

* refactor(rpc): input size validation in graph_compute

checks in favor of simpler direct comparisons, assuming 64-bit

* refactor(rpc): remove extra status code setting

Removes the explicit setting of `response.result = GGML_STATUS_FAILED`
when `create_node` returns `nullptr` within `graph_compute`.
Primary signal is the `false` return value in case of failure.

* refactor(rpc): remove redundant check for tensor->type

Breaks CI on ubuntu-cpu-make. Tensor type is uint32_t, thus
the check is not needed.

de7b41ef94 llama : greatly reduce output buffer memory usage (#6122)
* llama : greatly reduce logits memory usage

* llama : more compact state saving and reloading

* llama : fix lctx.n_outputs not being set before building graph

* perplexity : adapt to the logits API changes

* perplexity : fix Winogrande, use correct logits for second choice start

The first logits used to evaluate the second choice were not from
the end of the common prefix; instead, they were the logits from the end
of the first choice. This has been corrected.

The previous implementation sometimes had outliers in the scores of
choices for some tasks, and the logic to skip choices words
in the log-likelihood evaluation probably was an attempt to reduce those,
but it was complex and didn't quite seem to be the right thing.

This is simpler now, and the outlier scores aren't there anymore.

* perplexity : normalize spaces and punctuation in Winogrande sentences

* llama : fix embedding conditions

* llama : fix llama_get_embeddings_ith when the resulting id is 0

* llama : fix wrong n_outputs in llama_set_inputs

A mismatch happened when using a smaller n_ubatch than n_batch and then using
llama_batch_get_one(). The decision of what n_outputs should be now almost
fully depends on how lctx.n_outputs is set in llama_decode_internal.
The conditions are simpler this way.

* llama : when saving the state, recalculate n_outputs

This ensures the correct number of outputs for the entire previous batch
is stored in the session file, even when n_ubatch is smaller than n_batch.

* llama : fix not-skipping outputs of non-causal models

* llama : fix running a batch with n_outputs == 0

It previously worked because lctx.inp_out_ids was not initialized,
so it pointed to some garbage address which was somehow still valid when I
ran my tests.

* llama : keep same graph topology even when n_outputs == 0

* ggml : saner ggml_can_repeat with empty tensors

*  ggml : future-proof ggml_is_empty by using GGML_MAX_DIMS - 1

* ggml : do not multi-thread ops returning empty tensors

* ggml : make ggml_is_empty public and work with views

* llama : use a vector for ctx->output_ids

* llama : rework reallocation logic for llama_output_reserve

Now comparing the actual size with the new total size of the output buffer
to allow more efficient enabling and disabling of the embeddings
and/or logits output in the future.

* ggml : skip empty tensors in all backends

* llama : fix llama_output_reserve nullptr deref when new_size is 0

* perplexity : make Winogrande work as it does on master

The problems with the Winogrande implementation will
need to be fixed in a separate PR to ease review.

* llama : clearer error messages for invalid logits or embeddings ids

* llama : assert all models that can have inp_out_ids

Since the graph topology is now constant, this presence check
can be done even when there are no outputs.

* llama : assert logits and embd buffers exist before writing to them

* llama : handle errors from llama_output_reserve at call sites

* perplexity : make hellaswag and multiple-choice outputs identical to master

Due to how the KV cache is updated, the logprobs for tokens in a batch
are very slightly affected by the other tokens present in the batch,
so to make hellaswag and multiple-choice return exactly the same results
as on master, the last token of each sequence needs to be evaluated
even though its output is not used at all.

This will probably be changed back in the future to make these benchmarks
a tiny bit faster.

* perplexity : fix division by zero when using less than 100 multiple-choice tasks

* llama : allow loading state saved with a different ctx size

When loading a session file, the context size is now only required to be
at least enough to load the KV cells contained in that session file,
instead of requiring to use exactly the same context size as when saving.

Doing this enables the use-case of extending or shrinking the context size
of a saved session.

This breaks existing session files because the meaning of kv_buf_size
is slightly changed (previously it was the size of the whole KV cache,
now it's only the size of the saved part of it). This allows for
finer-grained sanity checks when loading in an effort to keep kv_buf_size
useful even when the kv_size is changed.

* llama : minor

ggml-ci

* readme : update recent API changes, and warn about Vulkan
