Studio: expose --parallel / -np flag on unsloth studio run (#5737)
* Studio: expose --parallel / -np on `unsloth studio run`
The CLI was hardcoding `llama_parallel_slots=4` in `run_kwargs` at
`unsloth_cli/commands/studio.py`, leaving users unable to tune the
concurrent decode slot count even though the engine, KV-cache math,
and `studio.backend.run.run_server(llama_parallel_slots=...)`
plumbing all already accepted any N. This change adds a `--parallel`
/ `--n-parallel` / `-np` typer option (default 4 -- matches the
previous hardcoded value), forwards it into `run_kwargs`, and pins
the new surface with 4 unit tests.
Per-request state in `routes/inference.py` is already isolated
(`cancel_event` and `prev_text` are per-request locals in every
streaming handler; the `_lock` / `_serial_load_lock` only wrap
load/unload, not chat completions), so no concurrency refactor is
needed alongside this -- the engine layer already handles N
concurrent requests on one loaded model when llama-server is told
to.
Range guards: 1 <= N <= 64. With higher N each slot gets ctx/N KV
cache; users tuning this should be aware that per-call context
shrinks proportionally.
`unsloth studio` (the bare default command, no subcommand) still
defaults to llama_parallel_slots=1 via `run_server`'s own default;
this PR does not change that path -- it only exposes the knob on the
one-liner `studio run` command that already silently used 4.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Forward --parallel through venv re-exec and drop colliding short aliases
`unsloth studio run` re-execs into the Studio venv when invoked from
outside it (the common path). The arg-builder forwards every typer
option but the new --parallel, so the child re-execs at the default 4
and any user value is silently dropped. Worse: pre-PR users who
already pass `-np N` as a pass-through extra (where llama.cpp's
last-wins parsing made it stick) silently lose N after this PR lands.
Forward --parallel explicitly in the re-exec arg list.
While auditing the re-exec path, also drop the colliding 1-char
short aliases -m (--model) and -f (--frontend) plus the redundant
-hfr. Click's short-option clustering had been silently mis-parsing
~11 llama-server short flags via the pass-through path: -fa as
`-f a`, -mg 0 as `-m g` + stray 0, -fitt 1024 as `-f itt` + stray
1024, -hff path as `-f f` + stray `-h path`, -cmoe / -cram / -sm /
-ncmoe etc. The docstring promise ("any flag this command does not
recognize is forwarded verbatim") was silently violated.
-hf (2-char) is kept because Click treats multi-char shorts atomically
(no clustering of -hff / -hfv / -hffv / -hft) and -hf is documented
in basics/api/README.md. --model / --hf-repo / --frontend long forms
all unchanged. studio_default keeps -f because it has no pass-through.
Tests:
- test_studio_run_parallel_flag.py: 8 new re-exec coverage cases
(all 3 aliases, 3 platforms via sys.platform mock, pre-PR `-np`
regression, mixed with pass-through extras).
- test_studio_run_short_alias_clashes.py (new): surface checks that
the removed shorts cannot reappear, plus 11 parametrized cases
proving each previously-broken llama-server short flag now passes
through verbatim, plus a happy-path test that documented -hf still
works for `org/repo:variant` syntax.
All 27 tests pass. Negative test (revert either fix) shows the new
tests catch the regression.

* Fix stale studio run docstring describing rejected llama-server flags
The pre-PR docstring listed --port, -c / --ctx-size, --api-key, -ngl,
--jinja, --flash-attn, --no-context-shift as "rejected with HTTP 400",
but only --port and --api-key (plus other networking / auth / model
identity / single-model UI flags) are actually in
studio/backend/core/inference/llama_server_args.py's denylist. -c /
-ngl / --jinja / --flash-attn / --no-context-shift are pass-through
and last-wins-override Studio's auto-set value.
Rewrite the docstring to match the real denylist groups and point at
the canonical source. Also add --parallel to one of the examples now
that it is a first-class flag.
* ci: broaden Linux + narrow Windows llama.cpp runtime patterns + trim #5741 comments (#5746)
* ci: broaden Linux llama.cpp runtime pattern to lib*.so*
#5741 patched the explicit Linux pattern list to add
``libllama-*-impl.so*`` after ggml-org/llama.cpp#23462 (between
b9279 and b9283) split each binary's entry code into a paired
``lib<binary>-impl.so`` shared library. Same class of upstream
repackaging will hit us again whenever a new shared lib is added.
Mirror what macOS already does and replace the per-lib list with a
single ``lib*.so*`` glob. ``copy_globs`` (line 3614) unions
patterns, so the per-variant ``libggml-cuda.so*`` / ``libggml-hip.so*``
entries were never filtering anything; the spec lives in
``runtime_payload_health_groups`` (line 5209) which keeps the
explicit minimum-required list per variant.
Dry-run against b9296-bin-ubuntu-x64.tar.gz: 40 files copied (all
ggml, llama, mtmd, impl variants + the two binaries we ship), 22
skipped (other CLIs, rpc-server, LICENSE). Functionally equal to
the post-#5741 set.
* cleanup: trim #5741 comments on the pydantic split
Comments added in #5741 explained the original bug in full each
time. They are mostly redundant with the commit message and the PR.
Trim them to one short paragraph per site.
No behavior change.
* ci: narrow Windows runtime pattern to llama-server.exe + llama-quantize.exe
Studio only invokes llama-server and llama-quantize. Mac and Linux
already filter to those two binaries; Windows was the odd one out
with ``*.exe`` copying every CLI upstream ships (llama-cli,
llama-bench, llama-mtmd-cli, ...).
Dry-run on b9296 (win cpu-x64, cpu-arm64, cuda-13.1, hip-radeon):
20 unused EXEs skipped per variant, all DLLs (incl. the new
llama-*-impl.dll family) still copied via ``*.dll``.
``existing_install_matches_choice`` already checks llama-server.exe
exists explicitly (line 5297), so the health gate is unchanged.
* Lower default weight_decay in RL config from 0.01 to 0.001 (#5747)
In full FT, AdamW weight decay shrinks the parameter directly so the
implicit prior is W -> 0. In LoRA the trained parameters are A and B
while the effective weight is W = W_init + (alpha/r) * B @ A; decaying
A and B separately drives BA -> 0, hence W -> W_init rather than 0.
The previous default of 0.01 inherited from full-FT recipes adds a
measurable pull on the merged adapter back toward the base model over
a few thousand steps. 0.001 keeps a small Frobenius-norm prior on
||A||^2 + ||B||^2 for numerical stability without meaningfully biasing
the merged weight toward init, and aligns with the value used across
the unsloth notebook templates.
* Studio: strip orphan tool_call XML leaking into visible content (#5735)
* Studio: strip orphan tool_call XML from streamed visible content
The speculative-buffer state machine in
`studio/backend/core/inference/llama_cpp.py` can slice a tool_call XML
block between the silent DRAINING path and the user-visible
content_accum, depending on when in the model's emission the BUFFERING
-> STREAMING -> DRAINING transitions fire. Three leak shapes were
observed in a 2026-05-22 sweep of 900 Qwen3.5 / Qwen3.6 GGUF runs:
Pre-fix XML leak rate: 20/900 (2.22%), concentrated 6.7% on the
larger Q8 / MTP configs:
Qwen3.6-35B-A3B Q8_0 4/60 (6.7%)
Qwen3.6-35B-A3B-MTP Q4 4/60 (6.7%)
Qwen3.5-35B-A3B Q8_0 3/60 (5.0%)
Qwen3.6-27B Q8_0 3/60 (5.0%)
The existing `_TOOL_XML_RE` only matched well-formed
`<tool_call>...</tool_call>` and `<function=...></function>` pairs, so
unterminated openings (close was DRAINED) and orphan closes (opening
was DRAINED) survived the strip and reached the user.
Fix relaxes the regex to also strip:
1. Orphan opening up to end-of-string: `(?:</tool_call>|\Z)`
2. Orphan closing tag: bare `</tool_call>` / `</function>`
Verified on the full sweep: 20/900 -> 0/900 (100% of detected leaks
eliminated). 16 unit tests in `test_tool_xml_strip.py` pin all three
leak shapes plus the well-formed cases, plus parametrised checks on
the 5 actual real-world leak samples from the sweep data.
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Studio: strip tail-only </parameter> orphan + tighten regex
The 2026-05-22 gdpval sweep surfaced a 4th XML-leak shape not caught
by the earlier regex: a bare `</parameter>\n\n` at end-of-buffer (7
of 192 trials, all Qwen3.5-27B + a few Qwen3.6-27B). The model emits
the full `<tool_call><function=...><parameter=...>...content...
</parameter></function></tool_call>` envelope, the speculative buffer
DRAINS the opening tags as intended, but EOS (max_tokens cutoff)
truncates the outer `</function></tool_call>` close, leaving just
`</parameter>` as the visible tail.
We strip this ONLY when end-anchored (`\s*\Z`) so legitimate
mid-text uses (user code samples, documentation discussing the
Qwen tool-call XML shape) survive. Verified on the 192-trial
gdpval corpus: before=7, after=0.
While at it, fold the five top-level alternations into three by
sharing tag-name and prefix subgroups:
<tool_call>... + <function=\w+>... + --> <(?:tool_call|function=\w+)>...
</tool_call> | </function> --> </(?:tool_call|function)>
Semantically identical (verified by replay over the 192-trial
corpus + adversarial inputs, 0 diffs) and 1.34x faster on real
workloads. Backtracking-safety pinned by two new perf guards
(256KB '<' spam, 1000x orphan opens).
Tests: 16 -> 28 (6 new functional + 4 well-formed-vs-orphan +
2 perf guards).
* Tighten comments in XML-strip regex and tests
Code says what it does; comments were repeating it. Strip the verbose
explanations down to the WHY-only bits (engine quirk, tail-anchor
rationale, real-world source of each test sample). No code changes.
inference.py: 21 -> 12 lines around _TOOL_XML_RE
test_tool_xml_strip.py: 343 -> 259 lines (-84)
Tests: 28/28 still pass.

* Address review: deny pass-through --parallel, preserve legacy short aliases, fix test harness
Round 1 review fixes for #5737:
1. Deny --parallel / --n-parallel / -np in the pass-through validator.
Without this, `unsloth studio run --model X --parallel 8 -- --parallel
999` would last-win-override the running llama-server slot count while
Studio's app.state.llama_parallel_slots and KV-cache fitting stay at
the typer value (8), so the resource plan and the running process
disagree. Also bypasses the typer 1..64 range guard. Reject so the
only path is the first-class typer flag.
2. Backwards-compat shim for -m / -hfr / -f. Dropping the short aliases
from typer broke any script using `unsloth studio run -m X` or
`-hfr Y` or `-f dist`. Add _consume_legacy_short_aliases which pops
EXACT whole-token matches (or `-x=value` inline form) from ctx.args
into the corresponding typer parameter. Clustered tokens (`-fa`,
`-mg`, `-fitt`, ...) are left in the pass-through tail unchanged.
--model becomes Optional with an explicit missing-required check
after the preprocessor so legacy `-m X` still satisfies the
"must specify a model" requirement.
3. Drop mix_stderr from CliRunner. Typer 0.25.1 / Click 8.4.1 removed
the kwarg; the test harness raised TypeError before exercising the
PR behaviour. Tests run cleanly on current and older Typer/Click.
4. Correct the -np regression test docstring. Pre-PR `-np 8` was
clustered by Click as `-p 8` (port=8) + stray `-n`, silently
breaking the port binding -- not "passed through as 8 slots". The
post-PR assertion (child gets --parallel 8) is unchanged.
5. Update studio run docstring listing rejected flags so it now
correctly includes --parallel / -np / --n-parallel.
New tests:
- test_llama_server_args.py: parametrized denylist coverage for
--parallel / --n-parallel / -np including equals-form, including
out-of-range bypass attempts (999, 0). is_managed_flag flips True.
- test_studio_run_short_alias_clashes.py: legacy -m / -hfr / -f
promote to typer params; --model X + -m Y conflict errors; clustered
-mg / -fa / -fitt still pass through (the original bug fix holds).
132 tests pass (98 backend + 34 cli).
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Extend legacy-alias shim tests for repo:variant, inline value form, and missing model
Three additional edge cases for the -m / -hfr / -f preprocessor:
- `-m unsloth/foo:UD-Q4_K_XL` round-trips through both the preprocessor
and _split_repo_variant so the child sees --model + --gguf-variant.
- `-m=foo` inline value form is promoted just like `-m foo`.
- Missing --model after the preprocessor raises typer.Exit(2) cleanly
(replacing typer's pre-PR required-flag enforcement now that --model
is Optional to allow the legacy promotion path).
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Scrub .github/workflows for staging push (matches staging base)
* Fix studio CLI argv handling and pass-through docstring drift
- studio/backend/core/inference/llama_server_args.py: drop the stale
``-np``/``--parallel`` entry from the docstring's pass-through tunable
list. These flags moved into _DENYLIST_GROUPS so the docstring now
contradicts the validator and would mislead future maintainers
debugging the ValueError from validate_extra_args(["--parallel","8"]).

Studio: forward llama-server args from unsloth studio run , activate unsloth run , and allow passing model:quant to load models (#5271)
* Studio: forward unknown CLI args directly to llama-server `unsloth studio run --model X --top-k 20 --chat-template-file foo.jinja` now passes the unknown flags through to the llama-server subprocess. Adds a denylist for flags Studio manages (port, -m, -c, --api-key, -ngl, --flash-attn, --no-context-shift, --jinja, GPU-fit, model-identity, ...) that returns HTTP 400 on collision. HTTP callers can supply the same list via LoadRequest.llama_extra_args. * Studio: accept `--model org/repo:variant` shorthand in `unsloth studio run` Mirrors llama.cpp's `-hf <repo>:<quant>` and ollama's pull syntax so `unsloth studio run --model unsloth/gpt-oss-20b-GGUF:UD-Q4_K_XL` is equivalent to `--model unsloth/... --gguf-variant UD-Q4_K_XL`. Local paths and Windows drive letters are preserved verbatim. If both an embedded variant and an explicit `--gguf-variant` are given and they disagree, the command fails with a clear error. * Studio: register `unsloth run` as alias for `unsloth studio run` Top-level `unsloth run --model ...` is now equivalent to `unsloth studio run --model ...`. Same context_settings, so unknown flags continue to pass through to llama-server. * Studio: let users override soft-managed llama-server flags from CLI Trims the denylist to flags Studio fundamentally cannot share with the user (model identity, --host/--port/--path/--api-prefix, --api-key, --ssl-*, --webui, --models-*). Soft-managed flags -- -c/--ctx-size, --parallel, --flash-attn, --no-context-shift, --jinja, -ngl, -t/--threads, --fit* -- now pass through and override Studio's auto-set version via llama.cpp's last-wins CLI parsing. Lets users tune their run on the spot: unsloth run --model X -c 131072 --parallel 1 --threads 32 * Studio: accept `-hf` / `-hfr` / `--hf-repo` as aliases for `--model` Matches llama-server's `-hf <repo>:<quant>` spelling so users coming from llama.cpp can use the same flag. Typer claims the aliases before the pass-through validator runs, so the HTTP-API denylist on those flags is unaffected. unsloth run -hf unsloth/gpt-oss-20b-GGUF:UD-Q4_K_XL |

Rename cli/ to unsloth_cli/ to fix namespace collision with stringzilla (#4393)
* Rename cli/ to unsloth_cli/ to fix namespace collision with stringzilla stringzilla installs a namespace package at cli/ (cli/split.py, cli/wc.py) in site-packages without an __init__.py. When unsloth is installed as an editable package (pip install -e .), the entry point script does `from cli import app` which finds stringzilla's namespace cli/ first and fails with `ImportError: cannot import name 'app' from 'cli'`. Non-editable installs happened to work because unsloth's cli/__init__.py overwrites the namespace directory, but this is fragile and breaks if stringzilla is installed after unsloth. Renaming to unsloth_cli/ avoids the collision entirely and fixes both editable and non-editable install paths. * [pre-commit.ci] auto fixes from pre-commit.com hooks for more information, see https://pre-commit.ci * Update stale cli/ references in comments and license files --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> |
