Nous Hermes 3. The Nous Hermes family of fine-tuned models have a solid reputation. Their most recent release came out in August, based on Meta's Llama 3.1:
Our training data aggressively encourages the model to follow the system and instruction prompts exactly and in an adaptive manner. Hermes 3 was created by fine-tuning Llama 3.1 8B, 70B and 405B, and training on a dataset of primarily synthetically generated responses. The model boasts comparable and superior performance to Llama 3.1 while unlocking deeper capabilities in reasoning and creativity.
The model weights are on Hugging Face, including GGUF versions of the 70B and 8B models. Here's how to try the 8B model (a 4.58GB download) using the llm-gguf plugin:
llm install llm-gguf
llm gguf download-model 'https://huggingface.co/NousResearch/Hermes-3-Llama-3.1-8B-GGUF/resolve/main/Hermes-3-Llama-3.1-8B.Q4_K_M.gguf' -a Hermes-3-Llama-3.1-8B
llm -m Hermes-3-Llama-3.1-8B 'hello in spanish'
Nous Research partnered with Lambda Labs to provide inference APIs. It turns out Lambda host quite a few models now, currently providing free inference to users with an API key.
I just released the first alpha of a llm-lambda-labs plugin. You can use that to try the larger 405b model (very hard to run on a consumer device) like this:
llm install llm-lambda-labs
llm keys set lambdalabs
# Paste key here
llm -m lambdalabs/hermes3-405b 'short poem about a pelican with a twist'
Here's the source code for the new plugin, which I based on llm-mistral. The plugin uses httpx-sse to consume the stream of tokens from the API.
NousResearch/DisTrO. DisTrO stands for Distributed Training Over-The-Internet - it's "a family of low latency distributed optimizers that reduce inter-GPU communication requirements by three to four orders of magnitude".
This tweet from @NousResearch helps explain why this could be a big deal:
DisTrO can increase the resilience and robustness of training LLMs by minimizing dependency on a single entity for computation. DisTrO is one step towards a more secure and equitable environment for all participants involved in building LLMs.
Without relying on a single company to manage and control the training process, researchers and institutions can have more freedom to collaborate and experiment with new techniques, algorithms, and models.
Training large models is notoriously expensive in terms of GPUs, and most training techniques require those GPUs to be collocated due to the huge amount of information that needs to be exchanged between them during the training runs.
If DisTrO works as advertised it could enable SETI@home style collaborative training projects, where thousands of home users contribute their GPUs to a larger project.
There are more technical details in the PDF preliminary report shared by Nous Research on GitHub.
I continue to hate reading PDFs on a mobile phone, so I converted that report into GitHub Flavored Markdown (to ensure support for tables) and shared that as a Gist. I used Gemini 1.5 Pro (gemini-1.5-pro-exp-0801) in Google AI Studio with the following prompt:
Convert this PDF to github-flavored markdown, including using markdown for the tables. Leave a bold note for any figures saying they should be inserted separately.
teknium/OpenHermes-2.5 (via) The Nous-Hermes and Open Hermes series of LLMs, fine-tuned on top of base models like Llama 2 and Mistral, have an excellent reputation and frequently rank highly on various leaderboards.
The developer behind them, Teknium, just released the full set of fine-tuning data that they curated to build these models. It’s a 2GB JSON file with over a million examples of high quality prompts, responses and some multi-prompt conversations, gathered from a number of different sources and described in the data card.
