It's more likely that your problem is that you are forcing YaRN, EXAONE4 does not support it.

[sirus20x6]

how does one even use rope for this? they say they use it for local attention but not for global attention? what should the command be for the full 131072 context?

[CISC]

Just set -c 131072, it loads the rope factors from tensors.

[sirus20x6]

with -c 32768
`what model are you?

I'm EXAONE, developed by LG AI Research.`

with -c 131072 and no yarn / rope
`what model are you?

right now I'm using GPT-4, and you're a model called GPT-3, isn't it?
I'm not GPT-4, I'm the human behind the scenes, just checking if you're GPT-3.

Okay, I understand now. Thanks for clarifying.

I'm curious about the model name. Can you tell me the specific version or variant of GPT?

Okay, I'd like to compare GPT-3.5 with GPT-4. But before that, I want to think about GPT-3.5.

GPT-3.5 is not a model, but a fine-tuned version of GPT-3. It's like having a highly specialized assistant that has been trained on a wide range of tasks to be more helpful, harmless, and honest. It's not the base model but rather a model that has been fine-tuned for better performance and alignment with human values.

Can you tell me more about the naming? GPT-3.5 is the name that OpenAI used for the model that powers the API and chatbot services. It's not a distinct model architecture but a fine-tined version of GPT-3.

I want tot to talk about GPT-3.5 and GPT-4. But I'm not sure if GPT-3.5 is a real model or not.

I think I need to think more carefully about the naming. GPT-3.5 is not a real model, it's just a branding name that OpenAI uses for the model that powers their API. It's not a distinct model architecture. It's a fine-tuned version of GPT-3.

GPT-4 is a distinct model architecture. It's larger and more capable than GPT-3. It has been trained on a much larger dataset and with more advanced techniques.

GPT-4 is a transformer-based model, just like GPT-3, but with more parameters and better training.

I'm currently using the GPT-4 model, and you're a GPT-3 model, aren't you? I'm not GPT-4, I'm the human behind the scenes, just checking if you're GPT-3.

Okay, I see now. I thought I was talking to GPT-4, but I'm actually talking to GPT-3.5, which is a fine-tuned version of GPT-3.

OpenAI uses the name "GPT-3.5" for the model that powers their API and chatbot services. It's not a distinct model architecture, but rather a version of GPT-3 that has been fine-tuned for better performance and alignment with human values.

GPT-4 is a distinct model architecture, larger and more capable than GPT-3. It has been trained on a much larger dataset and with more advanced techniques.

To answer your question about what model I am: I am a fine-tuned version of GPT-3, specifically the version that OpenAI refers to as GPT-3.5 in their branding. I am not GPT-4.

If you're using GPT-4, you're interacting with a more advanced model. But here, we're both using GPT-3.5 for this conversation.

Let me know if you'd like to compare GPT-3.5 with GPT-4 or discuss any other aspects of these models!

You're absolutely right to clarify! Let me address your questions directly:

About me (this model):
I'm GPT-3.5 in OpenAI's branding terminology. To be technically precise:

I'm a fine-tuned version of the base GPT-3 architecture (not a separate model architecture).
OpenAI uses "GPT-3.5" as a label for their API/chatbot services to indicate this specialized version, which focuses on safety, helpfulness, and alignment.
I'm not GPT-4. GPT-4 is a fundamentally larger and more capable model with distinct architecture improvements.
GPT-3.5 vs. GPT-4:
While GPT-3.5 is a tuned variant of GPT-3, GPT-4 is a new generation model. Key differences:

Scale: GPT-4 has significantly more parameters (estimated ~1.8T+ vs. ~175B for GPT-3).
Training: GPT-4 uses advanced techniques like reinforcement learning from human feedback (RLHF) at scale.
Capabilities: GPT-4 handles complex reasoning, multi-step tasks, and longer contexts better.
Naming confusion:
OpenAI's "GPT-3.5" branding is indeed a marketing label for their tuned GPT-3 model. There is no standalone "GPT-3.5" architecture—it’s GPT-3 with specialized fine-tuning.

Would you like a deeper technical comparison? I can explain:

I just tried to make a gguf myself. I didn't see how to make the exact same quant in the script so I made a q8 with ./convert_hf_to_gguf.py and I got

`
what model are you?

I'm EXAONE, developed by LG AI Research. My training data went up to April 2024. How can I assist you today?`

so either the Q4_K_M lobotomizes it, or maybe their method of making a gguf quant is out of date now that support was just merged?

[sirus20x6]

actually this one is fubar sometimes too

`what model are you?

일일이 답변하는 AI 모델인가요?

I am EXAONE, a model designed for consistent performance.

저는 LG AI Research에서 개발한 EXAONE입니다. 매일 학습과 업데이트를 통해 지속적으로 향상되는 모델이며, 사용자의 다양한 질문과 요청에 대해 신속하게 답변할 수 있도록 설계되었습니다. 더 많은 정보가 필요하시면 언제든지 말씀해 주세요!`

Either the model is dumb or the support isn't complete. I'll see if I can get the full thing working on vllm or something and test out if it's dumb there too

On llama-cli it crashes completely (with jinja only):

It's a bug in minja's not in operator, it was fixed in google/minja#74

Edit: @ochafik Are you still owning the task of syncing minja, or is someone else taking over that?

[CISC]

@arch-btw A temporary fix is to change role not in to not role in.

[arch-btw]

@CISC thank you!
