Add `-tm` / `--threads-mtmd` to control CPU thread count used during
multimodal image/audio processing (mmproj encoding), separate from the
main LLM thread count.
This allows running the LLM on GPU with minimal CPU threads (e.g. `-t 1`)
to reduce sync overhead, while using many threads (e.g. `-tm 16`) for
CPU-bound mmproj encoding with `--no-mmproj-offload`.
Fallback chain when `-tm` is not specified:
1. `--threads-batch` (-tb) — multimodal encoding is a batch/prefill-like
operation, so it makes sense to track with batch thread count
2. `--threads` (-t) — final default
Works with both mtmd-cli and llama-server.

The get_batch_ubatch() function unconditionally inflated n_batch and
n_ubatch whenever --mmproj was specified, regardless of whether the
mmproj model actually ran on the GPU. This boosted batch size applies
to both the main context and the MTP draft context, since
params_base.speculative.cparams_dft is derived from
common_context_params_to_llama(params_base).
When mmproj runs on CPU (--no-mmproj-offload), this batch inflation
is unnecessary for mmproj itself (CPU compute is sized by image
dimensions independently), but it still inflates the MTP compute buffer
proportionally. For large images (e.g. --image-max-tokens 4096), the
MTP compute buffer ballooned to ~2020 MiB and triggered an OOM even
though the mmproj model was fully on CPU and should have saved VRAM.
Restrict the batch inflation to !params.mmproj.path.empty() &&
params.mmproj_use_gpu so it only triggers when mmproj actually occupies
GPU memory. When mmproj runs on CPU, the existing per-chunk decode
splitting in mtmd_helper_decode_image_chunk_impl handles large images
correctly with the default batch size.

When `enable_thinking` is false (e.g. via `chat_template_kwargs: {thinking: false}`),
the Kimi-K2 parser was still extracting reasoning tokens and routing all output to
`reasoning_content` instead of `content`.
The fix aligns with how other thinking models (Qwen3, etc.) handle this: check both
`reasoning_format != NONE` and `enable_thinking` before enabling reasoning extraction.
Fixes#1685
* server: spec checkpoints for recurrent models
* fix: save/restore sampler state during speculative checkpoint
When speculative decoding rejects draft tokens and restores the
recurrent state checkpoint, the sampler (RNG, grammar, prev tokens)
must also be restored to maintain consistency. Without this, the
sampler state reflects the rejected draft tokens, leading to
potential divergence.
Uses common_sampler_clone() to snapshot the sampler before the
speculative batch decode, and restores it on rejection.

common/json-schema: fix: handle non-capturing groups (?:...) in JSON schema pattern converter (#21124)
The regex-to-grammar converter in _visit_pattern() crashes with SIGSEGV
when a JSON schema "pattern" field contains a non-capturing group (?:...).
Root cause: when the parser sees '(' followed by '?', it pushes a warning
but does not advance past '?:'. The recursive transform() call then
interprets '?' as a quantifier and calls seq.back() on an empty vector,
causing undefined behavior.
This commonly occurs when serving OpenAI-compatible tool calls from
clients that include complex regex patterns in their JSON schemas (e.g.,
date validation patterns like ^(?:(?:\d\d[2468][048]|...)-02-29|...)$).
The fix:
- Skip '?:' after '(' to treat non-capturing groups as regular groups
- For unsupported syntax (?=, ?!, etc.), skip to matching ')' safely,
handling escaped characters to avoid miscounting parenthesis depth
- Adjust the ')' unbalanced-parentheses check using direct char
comparisons instead of substr
- Add test cases for non-capturing groups (C++ only, as the JS/Python
implementations do not yet support this syntax)

jinja : handle empty expressions correctly (#20913)

raising a parser error, to match Jinja2 behavior.
- return a noop expression for empty computed member arguments
- return undefined when a computed member key evaluates to undefined
- add Jinja tests covering `a[]|default('fallback')` and `a[] is undefined`
* Handle undefined computed member properties
Move undefined-property handling to the common member access path, and add a test covering `a[undefined] is undefined`.
* Use default undefined value in member access
Initialize val and then return it when property is undefined.

handle an edge case where if UTF-8 parsing fails, it adds the non-ascii
character back to the output as a raw byte.

character \\ufffd to the output instead. This is the standard behavior
for various programming languages like Python, Rust, Go, etc.

common/gemma4 : handle parsing edge cases (#21760)
common: skip reasoning budget sampler when no budget is requested (#21870)
* common: skip reasoning budget sampler when no budget is requested
After I added thinking_start_tag / thinking_end_tag for gemma4 in #21697, the reasoning budget sampler gets unconditionally created even when no budget is configured (the default -1). The same applies to kimi_k2, lfm2, lfm2_5, and ministral_3 which also set these tags. The budget gets converted to INT_MAX, so the sampler never actually forces any tokens but still runs per-token checks (start tag matching in IDLE state, token-to-piece conversion + UTF-8 checks in COUNTING state).
More importantly, the mere existence of the sampler (non-null rbudget) disables backend sampling. Backend sampling lets the GPU select tokens directly, avoiding a full logits transfer from GPU to CPU every token. This could explain the 30% speed regression reported in #21784 (98 t/s to 70 t/s on Vulkan).
So I added a reasoning_budget_tokens >= 0 check to the sampler creation condition. When the budget is unlimited, the sampler is not created, backend sampling stays enabled, and no per-token overhead is added. When a budget is explicitly set (0, 128, 1024, etc.), the sampler is created and works as before.
* common: preserve rbudget when grammar is lazy
Following up on the review feedback on #21870: keep the reasoning budget sampler when grammar_lazy is true, so the thinking-block grammar suppression from #20970 still works when tools are in use. This way, we only skip the sampler when both no budget is set AND grammar is not lazy.

Blacklisted patterns (hidden):
- Per-layer device assignments ('Setting default device in layer')
- KV metadata dump header and entries
- Tensor type counts
- Model validation messages
- EOG/special token cache info
- Metadata printout (llm_load_print_meta, print_info)
- Layer sizes table

- LLAMA_ARG_CACHE_TYPE_K (string, e.g. "q8_0")
- LLAMA_ARG_CACHE_TYPE_V (string, e.g. "q8_0")
- LLAMA_ARG_MLOCK (bool, "1"/"true")
- LLAMA_ARG_K_CACHE_HADAMARD (bool, "1"/"true")
2. Call gpt_params_parse_from_env() from gpt_params_parse() so that
ALL tools (llama-cli, llama-bench, etc.) respect env vars, not
just llama-server. Env vars act as defaults; CLI flags override.
Follows the existing get_env() pattern and uses the same
LLAMA_ARG_ prefix convention as the other env vars.

jinja : add unordered_map include to value.h [no ci] (#19205)
jinja : add missing 'in' test to template engine (#19004) (#19239)
The jinja template parser was missing the 'in' test from
global_builtins(), causing templates using reject("in", ...),
select("in", ...), or 'x is in(y)' to fail with
"selectattr: unknown test 'in'".
This broke tool-calling for Qwen3-Coder and any other model
whose chat template uses the 'in' test.
Added test_is_in supporting array, string, and object containment
checks, mirroring the existing 'in' operator logic in runtime.cpp.
Includes test cases for all three containment types plus
reject/select filter usage.

mtmd : chat : Fix extra \n between text and media marker (#19595)
Thanks to @tugot17 for detecting and reporting the issue.
For vision models (e.g. LFM2.5-VL-1.6B and Qwen/Qwen3-VL-4B-Instruct) `llama-mtmd-cli` produces identical output to HF implementation.
However `llama-server` doesn't. I traced it down to extra newline
inserted after `<__media__>`.
This happens in `to_json_oaicompat`, that treats media markers as text
and joins all parts with `\n` separator.
PR introduces new type `media_marker` and uses it for media markers.
Extra logic is added to prevent insertion of newlines before and after
media markers.
With this change number of input tokens is identical to HF
implementation and as a result the output is also identical.
I explored other ways to address the issue
* remove completely `\n` between text parts in `to_json_oaicompat`
* merge text messages in server-common.cpp before sending them to `to_json_oaicompat`
Please propose alternative ways of fixing this issue.
