Release Notes - v1.31.5

Release Date: August 19, 2026

Overview

Version 1.31.5 introduces comprehensive whisper.cpp sampling parameters for both transcription and streaming modes in Bucky, allowing fine-grained control over decoding behavior including temperature, beam search, and greedy strategies. Documentation and BUI components have been updated to reflect these new capabilities.

Detailed Changes

New Features

Bucky Sampling Parameters

  • Author: William Kennedy
  • Added Temperature, TemperatureInc, EntropyThreshold, GreedyBestOf, BeamSize, BeamSearchPatience, and LengthPenalty fields to TranscribeConfig in sdk/bucky/model/transcribe.go
  • Added the same sampling parameters to StreamConfig in sdk/bucky/model/stream.go for streaming transcription sessions
  • Introduced constructor options: WithTemperature, WithTemperatureInc, WithEntropyThreshold, WithGreedyBestOf, WithBeamSearchPatience, and WithLengthPenalty for both transcribe and stream configs
  • Added parseWhisperOptions function in cmd/server/app/domain/audioapp/audioapp.go to parse whisper options from HTTP form values, exposing all new parameters through the API endpoint
  • Added comprehensive test coverage for sampling parameters in sdk/bucky/model/sampling_params_test.go
