Changelog • LM Studio 0.4.7

Build 4

Build 3

Fixed unintended parsing of tool calls within reasoning blocks
Fixed a bug where parallel tool calls would fail for some models (for example, GLM)
Fixed a bug in OpenAI-compatible /v1/responses which sometimes caused "Output items missing; timeline invariant violated"
Fixed $...$ parsing so plain currency/text (for example $10, $1.23, $37 trillion) is no longer incorrectly rendered as math
Fixed single-dollar boundary handling to reduce false positives when $ appears in normal prose
Fixed \[ \] and  handling so bracket/paren math parses correctly, and empty forms stay visible as literal text
Fixes responsive handling of models table on narrow screens, adds resizable column handles
Fixed a bug where Anthropic-compatible /v1/messages API would error when properties were not provided for a tool input schema
Expose Models Directory selector in Settings
Fixed tool calling parsing bugs for Qwen 3.5 and GLM models
- Tool call parameters with string type were sometimes incorrectly parsed as object/number/boolean
Added tool call grammar for gpt-oss models using llama.cpp engine, significantly increasing tool call success rate for these models (requires llama.cpp engines updated to v2.7.1 or later)

Build 2

Global chat search now takes into account chat titles
Add notification UI when LM Link versions are incompatible between devices
Fixed a bug creating a duplicate onboarding popover on the LM Link page
Make XML-like tool call parsing (e.g., Nemotron 3) more reliable for boolean values
Fixed a bug where clicking the Attach File button in chat input would lock the text input UI
Fixes a bug where
tags were showing as text in markdown tables
Fixed a responsive UI overlap bug on server page stacked content
Fixed a bug where an unnamed chat title would appear as the chat id in the chat sidebar search results
Fixed a bug where on certain devices, the app would crash if an image is fed to a vision model
Fixed a bug where model load guardrails and resource usage estimates were inaccurate for some models
Anthropic-compatible /v1/messages API now surfaces errors when the model generates an invalid tool call, enabling Claude Code to recover gracefully

Build 1

New default: "separate reasoning_content and content in API responses" is now ON by default in order to improve compatibility with /v1/chat/completions clients
- If your use case requires this setting to be off (previous default), you can disable it in the Developer Settings
Fixed app header nav button hotkeys
Add parallel parameter to /api/v1/load endpoint
Add presence_penalty sampling parameter
Fix hover effect visual bug on Model Picker model options in chat input
Fixed responsive UI styling on the LM Link page
[Linux] Fix regression caused by some app files having a space in their name.
Fix OpenAI-compatible /v1/responses endpoint erroring on none and xhigh reasoning effort
Fixed a bug where /v1/responses responses included logProbs for MLX models even if message.output_text.logprobs was omitted
