    feat(studio): editable context length with Apply/Reset for GGUF settings (#4592)

    • feat(studio): editable context length with Apply/Reset for GGUF model settings

    Previously the Context Length field was read-only and the backend
    hardcoded -c 0, ignoring custom values entirely. KV Cache Dtype also
    triggered an immediate model reload with no way to cancel.

    Backend:

    • llama_cpp.py: pass the actual n_ctx value to -c instead of always 0
    • models/inference.py: relax max_seq_length to 0..1048576 (0 = model
      default) so GGUF models with large context windows are supported

    Frontend:

    • chat-runtime-store: add customContextLength and loadedKvCacheDtype
      state fields for dirty tracking
    • chat-settings-sheet: make Context Length an editable number input,
      stop KV Cache Dtype from auto-reloading, show Apply/Reset buttons
      when either setting has been changed
    • use-chat-model-runtime: send customContextLength as max_seq_length
      in the load request, reset after successful load
    • fix: preserve maxSeqLength for non-GGUF models in load request

    customContextLength ?? 0 sent max_seq_length=0 for non-GGUF models,
    breaking the finetuning/inference path that needs the slider value.

    Now uses a three-way branch:

    • customContextLength set: use it (user edited GGUF context)
    • GGUF without custom: 0 (model's native context)
    • Non-GGUF: maxSeqLength from the sampling slider
    • fix: keep max_seq_length default at 4096 for non-GGUF callers

    Only relax the bounds (ge=0 for GGUF's "model default" mode,
    le=1048576 for large context windows). The default stays at 4096
    so API callers that omit max_seq_length still get a sane value
    for non-GGUF models.

    • [pre-commit.ci] auto fixes from pre-commit.com hooks

    for more information, see https://pre-commit.ci

    • fix(studio): rename trust remote code toggle and hide when no model selected
    • Rename "Trust remote code" to "Enable custom code"
    • Shorten subtitle to "Only enable if sure"
    • Hide the toggle when no model is loaded (already hidden for GGUFs)
    • fix: restore ge=128 for max_seq_length validation

    Keep the minimum at 128 so the API rejects nonsensical values.
    GGUF path now sends the model's native context length (from
    ggufContextLength) instead of 0 when the user has not customized it.
    The upper bound stays at 1048576 for large-context GGUF models.

    • feat(studio): replace Context Length input with slider

    Use a ParamSlider (512 to model's native context, step 512) instead
    of a small number input. Shows "Max" when at the model's native
    context length. Consistent with the other slider controls in the
    settings panel.

    • feat(studio): add editable number input alongside Context Length slider

    The slider and number input stay synced -- dragging the slider updates
    the number, typing a number moves the slider. The input also accepts
    values beyond the slider range for power users who need custom context
    lengths larger than the model default.

    • fix(studio): widen context length input and use 1024 step for slider

    Make the number input wider (100px) so large values like 262144 are
    fully visible. Change slider step from 512 to 1024 and min from 512
    to 1024.

    • fix(studio): context length number input increments by 1024

    • fix(studio): cap context length input at model's native max

    Adds max attribute and clamps typed/incremented values so the context
    length cannot exceed the GGUF model's reported context window.

    • fix(studio): point "What's new" link to changelog page

    Changed from /blog to /docs/new/changelog.

    • fix(studio): preserve custom context length after Apply, remove stale subtitle
    • After a reload with a custom context length, keep the user's value
      in the UI instead of snapping back to the model's native max.
      ggufContextLength always reports the model's native metadata value
      regardless of what -c was passed, so we need to preserve
      customContextLength when it differs from native.
    • Remove "Reload to apply." from KV Cache Dtype subtitle since the
      Apply/Reset buttons now handle this.
    • feat(studio): auto-enable Search and Code tools when model supports them

    Previously toolsEnabled and codeToolsEnabled stayed false after loading
    a model even if it reported supports_tools=true. Now both toggles are
    automatically enabled when the loaded model supports tool calling,
    matching the existing behavior for reasoning.

    • fix(studio): auto-enable tools in autoLoadSmallestModel path

    The suggestion cards trigger autoLoadSmallestModel which bypasses
    selectModel entirely. It was hardcoding toolsEnabled: false and
    codeToolsEnabled: false even when the model supports tool calling.
    Now both are set from the load response, matching the selectModel
    behavior. Also sets kvCacheDtype/loadedKvCacheDtype for dirty
    tracking consistency.

    • fix(studio): re-read tool flags after auto-loading model

    The runtime state was captured once at the start of the chat adapter's
    run(), before autoLoadSmallestModel() executes. After auto-load enables
    tools in the store, the request was still built with the stale snapshot
    that had toolsEnabled=false. Now re-reads the store after auto-load so
    the first message includes tools.

    • fix(studio): re-read entire runtime state after auto-load, not just tools

    The runtime snapshot (including params.checkpoint, model id, and all
    tool/reasoning flags) was captured once before auto-load. After
    autoLoadSmallestModel sets the checkpoint and enables tools, the
    request was still built with stale params (empty checkpoint, tools
    disabled). Now re-reads the full store state after auto-load so the
    first message has the correct model, tools, and reasoning flags.

    • feat(studio): add Hugging Face token field in Preferences

    Adds a password input under Configuration > Preferences for users to
    enter their HF token. The token is persisted in localStorage and
    passed to all model validate/load/download calls, replacing the
    previously hardcoded null. This enables downloading gated and private
    models.

    • fix(studio): use model native context for GGUF auto-load, show friendly errors

    The auto-load paths and selectModel for GGUF were sending
    max_seq_length=4096 which now actually limits the context window
    (since we fixed the backend to respect n_ctx). Changed to send 0
    for GGUF, which means "use model's native context size".

    Also replaced generic "An internal error occurred" messages with
    user-friendly descriptions for known errors like context size
    exceeded and lost connections.

    LoadRequest validation changed to ge=0 to allow the GGUF "model
    default" signal. The frontend slider still enforces min=128 for
    non-GGUF models.

    • fix(studio): filter out FP8 models from model search results

    Hide models matching -FP8- or FP8-Dynamic from both the
    recommended list and HF search results. These models are not
    yet supported in the inference UI.
