Kuwa v0.3.4 provides a feature to customize third-party API keys, allowing users to connect to APIs other than Gemini and ChatGPT. Many users find it difficult to run large models like Llama3.1 70B locally, and Groq offers a free cloud API to use these large models. This article will explain how to connect Groq API in Kuwa v0.3.4.

Applying for a Groq API Key​

1. Log in to Groq Cloud

2. Create a new API key

Enter a memorable API key name and copy the generated API key.
Be sure to save the API key, as it will not be displayed again after the dialog box closes.

Configuring Kuwa​

1. Enter the API Key

Please enter the API key obtained in the previous step in "User Settings > API Management > Custom Third-Party API Key".

2. Use the Model

v0.3.4 comes with a pre-built model called "Llama3.1 70B (Groq API)".
After entering the Groq API key, you can use this model.

National Taiwan University's Liang-Hsuan Tseng and NTU COOL team released the Cool-Whisper model last night (7/17), which is suitable for recognizing Taiwanese pronunciation Chinese or mixed Chinese-English audio files.
Kuwa can directly apply it by simply modifying the Modelfile.

Setup Steps​

1. Refer to the Whisper setup tutorial to start the Whisper executor

   • The Cool-Whisper model is approximately 1.5 GB in size and will occupy up to 10 GB of VRAM during execution

2. Create a new bot named Cool-Whisper in the store, select Whisper as the base model, and fill in the following model settings file, focusing on the PARAMETER whisper_model andybi7676/cool-whisper parameter

   SYSTEM "加入標點符號。"
   PARAMETER whisper_model andybi7676/cool-whisper #base, large-v1, large-v2, large-v3, medium,  small, tiny
   PARAMETER whisper_enable_timestamp True #Do not prepend the text a timestamp
   PARAMETER whisper_enable_diarization False
   PARAMETER whisper_diar_thold_sec 2
   PARAMETER whisper_language zh #for auto-detection, set to None, "" or "auto"
   PARAMETER whisper_n_threads None #Number of threads to allocate for the inferencedefault to min(4, available hardware_concurrency)
   PARAMETER whisper_n_max_text_ctx 16384 #max tokens to use from past text as prompt for the decoder
   PARAMETER whisper_offset_ms 0 #start offset in ms
   PARAMETER whisper_duration_ms 0 #audio duration to process in ms
   PARAMETER whisper_translate False #whether to translate the audio to English
   PARAMETER whisper_no_context False #do not use past transcription (if any) as initial prompt for the decoder
   PARAMETER whisper_single_segment False #force single segment output (useful for streaming)
   PARAMETER whisper_print_special False #print special tokens (e.g. <SOT>, <EOT>, <BEG>, etc.)
   PARAMETER whisper_print_progress True #print progress information
   PARAMETER whisper_print_realtime False #print results from within whisper.cpp (avoid it, use callback instead)
   PARAMETER whisper_print_timestamps True #print timestamps for each text segment when printing realtime
   PARAMETER whisper_token_timestamps False #enable token-level timestamps
   PARAMETER whisper_thold_pt 0.01 #timestamp token probability threshold (~0.01)
   PARAMETER whisper_thold_ptsum 0.01 #timestamp token sum probability threshold (~0.01)
   PARAMETER whisper_max_len 0 #max segment length in characters
   PARAMETER whisper_split_on_word False #split on word rather than on token (when used with max_len)
   PARAMETER whisper_max_tokens 0 #max tokens per segment (0 = no limit)
   PARAMETER whisper_speed_up False #speed-up the audio by 2x using Phase Vocoder
   PARAMETER whisper_audio_ctx 0 #overwrite the audio context size (0 = use default)
   PARAMETER whisper_initial_prompt None #Initial prompt, these are prepended to any existing text context from a previous call
   PARAMETER whisper_prompt_tokens None #tokens to provide to the whisper decoder as initial prompt
   PARAMETER whisper_prompt_n_tokens 0 #tokens to provide to the whisper decoder as initial prompt
   PARAMETER whisper_suppress_blank True #common decoding parameters
   PARAMETER whisper_suppress_non_speech_tokens False #common decoding parameters
   PARAMETER whisper_temperature 0.0 #initial decoding temperature
   PARAMETER whisper_max_initial_ts 1.0 #max_initial_ts
   PARAMETER whisper_length_penalty -1.0 #length_penalty
   PARAMETER whisper_temperature_inc 0.2 #temperature_inc
   PARAMETER whisper_entropy_thold 2.4 #similar to OpenAI's "compression_ratio_threshold"
   PARAMETER whisper_logprob_thold -1.0 #logprob_thold
   PARAMETER whisper_no_speech_thold 0.6 #no_speech_thold
   

   

3. You can now use the Cool-Whisper model for speech recognition. The following figure shows the use of Whisper and Cool-Whisper for recognizing mixed Chinese-English audio files, which can accurately recognize mixed Chinese-English scenarios

Kuwa v0.3.1 adds Kuwa Painter based on the Stable Diffusion image generation model,
You can generate an image by inputting a text, or upload an image and generate an image with a text.

Kuwa v0.3.1 has preliminary support for commonly used visual language models (VLMs). In addition to text inputs, such models can also take images as input and respond to user instructions based on the content of the images. This tutorial will guide you through the initial setup and usage of VLMs.

Kuwa v0.3.1 adds Kuwa Speech Recognizer based on the Whisper speech recognition model, which can generate transcripts by uploading audio files, supporting timestamps and speaker labels.

Known Issues and Limitations​

Hardware requirements​

The default Whisper medium model is used with speaker diarization disabled. The VRAM consumption on GPU is shown in the following table.

Known limitations​

1. Currently, the input language cannot be detected automatically and must be specified manually.
2. Currently, the speaker identification module is multi-threaded, causing the model to be reloaded each time, resulting in a longer response time.
3. Content is easily misjudged when multiple speakers speak at the same time.

Even if the model is not downloaded on the client side, you can use Kuwa to connect to the cloud model for chat and RAG applications. This article will guide you through the process of applying for Google's free Gemini Pro API key and configuring it in Kuwa.

Applying for a Gemini Pro API Key​

1. Visit Google AI Studio - Get API key and click "Get API key"
   

v0.3.0 has added the RAG toolchain, which allows users to drag and drop their on-premises file folders to build their own vector database and do QnA. This article will guide you through how to use Kuwa's RAG toolchain to build your own vector database and related Bot.

Windows Version Instruction​

1. Drag a single file or a file directory to the Create VectorDB shortcut on the desktop to open it with this script. If you don't have this shortcut, you can drag the file to C:\kuwa\GenAI OS\windows\construct_rag.bat
