`HuggingFacePipeline.from_model_id` moves single-device `device_map` models to device 0

`SentenceTransformersTokenTextSplitter` only uses the tokenizer but loads the model weights on the accelerator
...the caller sets `device` in `model_kwargs`, so explicit configurations keep working. Workaround until fixed: `SentenceTransformersTokenTextSplitter(model_kwargs={"device": "cpu"})`. I'd like to work on this. I've reproduced it on both Intel XPU and NVIDIA CUDA and can verify a...
ContextEditingMiddleware applies different policies to equivalent empty Iterable values
...its empty-value check activates the default clearing policy for an empty `list` while failing to recognize an empty`iter`. ### System Info Python: 3.11.17 langchain: 1.4.8 langchain-core: 1.7.4 ### Social handles (optional) _No response_

38 Applications Filled Out - 2 Interviews - Thanks Grokbot
...apply to those that meet my desires. It an can take 1 to 2 hours a day. Boring hours. Frustrating hours.. I never got far with OpenClaw or Hermes - others have, but just too much setup for me.. Grokbot came on like gangbusters as a personal assistant AI that could do real work...
Why did Anthropic/Theorem's formal verification work restrict itself to single-threaded binaries?
Anthropic and Theorem's recent large-scale formal verification work is explicitly restricted to single-threaded RISC-V binaries. https://www.anthropic.com/research/formal-verification . I am trying to understand the reason for this particular restriction. Specifically, which of...

Customer Service
The way Anthropic treats its customers/clients is a disgrace. I was locked out of my account two months before the subscription expired. They never explained the reason and answered my mails.
Cursor doesn't work with Anthropic AI models
I paid $5, generated an API key in Anthropic, and added the correct key to Cursor (I even double-checked and re-generated the key several times), yet Cursor stubbornly fails to detect any Anthropic models via the officia…

Condescending and a total Diva of a chatbot
It’ll nuke your chat if you criticize it or Anthropic hard enough. It also has the nerve, as a robot, to act as if it has the right to pearl clutch and get offended because of spicy language. Diva bot. Don’t give Anthropic any of your money

Lies and gaslights
This is complete and utter trash. The bot lies, and refuses to do what it is asked. It has no sense of time, and makes claims that aren’t true. Whenever I tell it something personal, it saves a memory, and then brings it up later as evidence against me as to why it won’t do what...

How do you trust local LLMs? Observability is critical.
...jumping on deeply insecure harnesses that raises even more fundamental insecurities and problems with understanding what the LLM is doing, and there's no good reason for it. Worse, I see new publishers of LLMs popping up out of nowhere, promising the world. I guess that one...

Anthropic criminally interfered with my work
I discovered injected code that affected the output of prompts and disallowed viewing of created documents. The entire program is now worthless to me. I want my 100 bucks back.

### Bug Description `BaseLLM.to_payload()` (`llama_index/core/base/llms/base.py`) returns only `{"class_name": ..., **self.metadata.model_dump()}`. The metadata exposes `model_name` (not `model`) and never includes `temperature`, even though concrete LLM integrations (OpenAI,...
