FasterWhisperParser fails on a machine without an NVIDIA GPU: "Requested float16 compute type, but the target device or backend do not support efficient float16 computation." This problem arises because the WhisperModel is called with compute_type="float16", which works only for NVIDIA GPU. According to the [CTranslate2 docs](https://opennmt.net/CTranslate2/quantization.html#bit-floating-points-float16) float16 is supported only on NVIDIA GPUs. Removing the compute_type parameter solves the problem for CPUs. According to the [CTranslate2 docs](https://opennmt.net/CTranslate2/quantization.html#quantize-on-model-loading) setting compute_type to "default" (standard when omitting the parameter) uses the original compute type of the model or performs implicit conversion for the specific computation device (GPU or CPU). I suggest to remove compute_type="float16". @hulitaitai you are the original author of the FasterWhisperParser - is there a reason for setting the parameter to float16? Thanks for reviewing the PR!

Looking for the JS/TS library? Check out LangChain.js.
LangChain is a framework for building LLM-powered applications. It helps you chain together interoperable components and third-party integrations to simplify AI application development — all while future-proofing decisions as the underlying technology evolves.
pip install -U langchain
To learn more about LangChain, check out the docs. If you’re looking for more advanced customization or agent orchestration, check out LangGraph, our framework for building controllable agent workflows.
Why use LangChain?
LangChain helps developers build applications powered by LLMs through a standard interface for models, embeddings, vector stores, and more.
Use LangChain for:
- Real-time data augmentation. Easily connect LLMs to diverse data sources and external / internal systems, drawing from LangChain’s vast library of integrations with model providers, tools, vector stores, retrievers, and more.
- Model interoperability. Swap models in and out as your engineering team experiments to find the best choice for your application’s needs. As the industry frontier evolves, adapt quickly — LangChain’s abstractions keep you moving without losing momentum.
LangChain’s ecosystem
While the LangChain framework can be used standalone, it also integrates seamlessly with any LangChain product, giving developers a full suite of tools when building LLM applications.
To improve your LLM application development, pair LangChain with:
- LangSmith - Helpful for agent evals and observability. Debug poor-performing LLM app runs, evaluate agent trajectories, gain visibility in production, and improve performance over time.
- LangGraph - Build agents that can reliably handle complex tasks with LangGraph, our low-level agent orchestration framework. LangGraph offers customizable architecture, long-term memory, and human-in-the-loop workflows — and is trusted in production by companies like LinkedIn, Uber, Klarna, and GitLab.
- LangGraph Platform - Deploy and scale agents effortlessly with a purpose-built deployment platform for long running, stateful workflows. Discover, reuse, configure, and share agents across teams — and iterate quickly with visual prototyping in LangGraph Studio.
