In <https://github.com/ollama/ollama/issues/11704#issuecomment-3177380197>
I noticed that hyphens in function names could possibly cause the model
to become confused. Later in that issue I found other explanations, but
at a minimum tool names with spaces in them are confusing to the model
because of the prompt format.

In this change I create a mapper that converts arbitrary tool names into
valid typescript identifiers. It's a little overly strict in that it
doesn't allow all unicode characters that might be valid in ts
identifiers, but it's still very permissive. Since mappings aren't
reversible, we must temporarily store this mapping in order to unmap it
if the model comes back with a call. We also handle the case where
multiple mappings collide into the same mapping and append a counter to
the end to make them unique

server: add debug option for printing out prompt instead of calling model

Docker build requires build-args to be defined.  This ensures the release.yaml settings will be used.

* test: improve scheduler/concurrency stress tests

The scheduler test used to use approximate memory figures and would often
over or under shoot a systems capcity leading to flaky test results.
This should improve the reliability of this scenario by leveraging
ps output to determinie exactly how many models it takes to
trigger thrashing.

The concurrency test is also refined to target num_parallel + 1 and handle
timeouts better.

With these refinements, TestMultiModelConcurrency was redundant

* test: add parallel generate with history

TestGenerateWithHistory will help verify caching and context
are properly handled while making requests

* test: focus embed tests on embedding models

remove non-embedding models from the embedding tests

This reverts commit dc5a6454.

This changes the memory allocation strategy from upfront estimation to
tracking actual allocations done by the engine and reacting to that. The
goal is avoid issues caused by both under-estimation (crashing) and
over-estimation (low performance due to under-utilized GPUs).

It is currently opt-in and can be enabled for models running on the
Ollama engine by setting OLLAMA_NEW_ESTIMATES=1. Behavior in other
cases is unchanged and will continue to use the existing estimates.

if there's no transformation to the tensor and the input and output
types match, copy directly into the writer. also read from a bufio with
a 32K buffer

* fix: Fix support for arch-specific ggml-cpu source files with new arrangement

In https://github.com/ggml-org/llama.cpp/pull/13892, all arch-specific
implementations were split out into a nested tree structure under
ggml-cpu/arch. This conflicts with standard CGO layout where all
arch-specific source files are expected to live in the same directory as
the parent go module and use suffixes based on GOOS and GOARCH. As such,
there were really two options for getting this to work:

1. Add a patch on top of the GGML sync to rearrange the files to match the
GO layout convention
2. Use CGO directives to conditionally include the nested source files in
the compilation units

This commit does (2) in order to minimize the set of changes needed on top
of the upstream file layout. To get this to work, there are two key things
needed:

1. In cpu.go, #cgo directives are added to explicitly set __${GOARCH}__ in
the preprocessor directives
2. In arch-impls.c|cpp, use an #ifdef | #elif defined | #endif chain to
explicitly include the .c|.cpp files for the given architecture from the
nested directory

Some users expect the rocm bundles to be self-sufficient, but are designed to be additive.

some of the new models need a few more valid responses to pass

We prefer the nvcuda library, which reports driver versions. When we
dropped cuda v11, we added a safety check for too-old drivers.  What
we missed was the cudart fallback discovery logic didn't have driver
version wired up.  This fixes cudart discovery to expose the driver
version as well so we no longer reject all GPUs if nvcuda didn't work.

Prior to this change our official binaries contained both JIT PTX code and
the cubin binary code for our chosen compute capabilities. This change
switches to only compile the PTX code and rely on JIT at runtime for
generating the cubin specific to the users GPU.  The cubins are cached
on the users system, so they should only see a small lag on the very
first model load for a given Ollama release.  This also adds the first
generation of Blackwell GPUs so they aren't reliant on the Hopper PTX.

This change reduces the ggml-cuda.dll from 1.2G to 460M

Some AMD GPUs do not provide UUIDs and report only "XX". In these
cases, we should use the ordinal ID as an alternate identifier.
This is the same as we always need to do on Windows for AMD.

In addition, this prints out the ID for each GPU when enumerating
them for easier debugging in the future.

We already run flash attention on CPUs in cases where we have
partial offloading but were disabling it if running on pure CPU,
 which is unnecessary.

server: fix error when parsing bad harmony tool calls

Thanks @moll for reporting!

Fixes: #11781

This patch modifies Ollama to allow grouping GPUs to memory-fit to the requested model, instead of the former algorithm of using one GPU distributing over all available GPUs.

Benefits:
 - Lower amount of (PCIe-)bus communication between GPUs - especially when they are not very high speed
 - Allowing unallocated GPUs to get into power-saving mode.
 - Significantly reduce VRAM allocation when using more than 2 GPUs in a system
 - Due to the reduced memory allocation, you can run more models simultaneously.

Callers can set a backend buffer type to be no-alloc, meaning that
it does not allocate memory for tensors or operations. This can
be used for calculating memory requirements. Tensors and graphs
must be recreated with no-alloc set to false before loading data.

Defaults to false for newly created backend buffer types.

In order to iteratively find the best memory allocation, we need to
be able to free backend memory so we can try again.

For many backend data structures, GGML defines a typedef of a pointer
type and returns these from functions. In most cases, CGo understands
that these are interchangable but some parts of Go (such as generics)
think they are two different types. We should prefer the form that
GGML uses.

Also wires up support to override the default "smol" model

gpt-oss works best with a context length of at least 8k. However,
for GPUs with limited amount of VRAM, there is a significant
performance hit to this increased context. In these cases, we
switch to the Ollama default of 4k

openai: always provide reasoning

We were missing passing along thinking if content was nil (as opposed
to empty string)

Also added a test for content not being passed, which was the real cause
of <https://github.com/ollama/ollama/issues/11704>, since with the way
`Content` is typed, not passing it and empty string are distinct

openai: when converting role=tool messages, propagate the tool name

Added support for converting both `name` and `tool_call_id` fields,
which different clients might provide. `name` is a legacy field from the
OpenAI completions API. For `tool_call_id` we inspect previous messages
and look for a matching tool call ID and grab its name

Issue: https://github.com/ollama/ollama/issues/11704

openai: allow for content _and_ tool calls in the same message

Previously our OpenAI chat completions compat layer assumed that tool
calls and content would never be provided together, but this is not a
correct assumption. Content is only optional when tool calls are
present, but tool calls and content can be provided together
