LLM Implementations
ChatGPT and its competitors
Small Language Models
These are models with hundreds of millions or billions of parameters and tuned to work offline, including Microsoft researchers have developed and released two SLMs, namely Phi and Orca. French AI startup Mistral has released Mixtral-8x7B, which can run on a single computer (with plenty of RAM). Google has Gemini Nano, which can run on smartphones.
See Li et al. (2024)
TinyLlama is yet another new language model. TinyLlama is small: 1B parameters, but more than that, only requires 550 MB of memory to run. It was designed for small mobile and embedded devices.

Evaluating GPT-4:
Coagulopath started the discussion but no longer thinks it’s gotten worse. Using example queries about Italian history and rock music, he shows there’s much nuance in how to interpret the accuracy of an answer and it’s impossible to say whether the later models are better or worse.
in Is GPT-4 getting worse over time? AI Snake Oil argues that no, GPT-4 is not getting worse like some studies have claimed. Good discussion of how you would dissect an LLM.
Amazon Olympus
This week, Amazon completed the second phase of a deal announced last September, when it committed to investing up to $4 billion in OpenAI rival Anthropic. The additional $2.75 billion invested is Amazon’s largest check ever into another company and yet another signal of how critical the development of large language models has become to Big Tech.
The training data for the secretive project is reportedly vast. The model will have a whopping 2 trillion parameters, which are the variables that determine the output of a given model, making it one of the largest currently in development. In comparison, OpenAI’s GPT-4 LLM has “just” one trillion parameters, according to Reuters.

Google (Gemini)
Getting Started with Gemini 1.5 Pro and Google AI Studio:
Why Google missed the boat on GPT-3 OpenAI engineer explains that Google’s internal TPU usage made it difficult to go all-in on the technology.
Known by the code-name Bard, Google’s Gemini 1.5 was announced in February 2024 and available to everyone for $20/month. It has a 1M token context window, which is enough to handle several books and more. By April 2024, it was already sustaining 25% the traffic of ChatGPT.
See Summary from Zvi
Technically, Gemini builds on Google’s world-class infrastructure and uses Ring Attention with Blockwise Transformers, to breaks long contexts into pieces to be computed individually even as the various devices computing those pieces simultaneously communicate to make sense of the context as a whole; in this case memory requirements scale linearly with context length, and can be extended by simply adding more devices to the ring topology.1
To use the larger context window, you’ll need AI Studio (I joined the waitlist)
Gemini Advanced is part of the Google One Premium Plan and costs $19/month. It includes 2TB of storage.
Google has built a new foundation model for time series. Like language models, and unlike most time series models, TimesFM is pretrained using time series data. It excels at zero-shot predictions.

Is the 41% quality gap “slight”? IMO, it’s not. Our experiences have shown that a 50-to-60 improvement is significantly easier than a 80-to-90 improvement.
Groq
Not to be confused with the X “Grok”, this is a super-fast interference engine built on other LLMs, including Llama and Mixtral.
LLama (Meta)
It was trained on 2T tokens and they have models up to 70B parameters. The paper linked in the blog has rich details and impressive tidbits that the community has guessed at but never confirmed, primary of which is around the absolute foundational nature of training the reward model properly. It’s harder to get right than it seems.
Meta’s Llama model used 2,048 Nvidia A100 GPUs to train on 1.4 trillion tokens, a numerical representation of words, and took about 21 days, according to a CNBC report in March. (SCMP)
Nathan Lambert writes a Llama 2: an incredible open LLM on how Meta is continuing to deliver high-quality research artifacts and not backing down from pressure against open source.
While doubling the training corpus certainly helped, folks at Meta claim the reward model and RLHF process was key to getting a safe and useful model for Llama 2’s release. If you didn’t have time to read the full technical paper, this post is an excellent summary of key ideas from the head of RLHF at HuggingFace.

Phi 3 is a series of models, 3B-14B in size, which perform exceptionally well on modern benchmarks. The 3B model claims to outperform the original ChatGPT model. Weights have been released. There is a variant available with a 128k context length.

trained a prototype LLM (Grok-0) with 33 billion parameters. This early model approaches LLaMA 2 (70B) capabilities on standard LM benchmarks but uses only half of its training resources. In the last two months, we have made significant improvements in reasoning and coding capabilities leading up to Grok-1, a state-of-the-art language model that is significantly more powerful, achieving 63.2% on the HumanEval coding task and 73% on MMLU.

Mistral (France)
https://mistral.ai/ (via The Generalist) Founded by Guillaume Lample, Arthur Mensch, and Timothe Lacroix to build an ecosystem hinged on first-class open-source models. This ecosystem will be a launchpad for projects, teams, and eventually companies, quickening the pace of innovation and creative usage of LLMs.
Mistral-7B-v0.1 is a small, yet powerful model adaptable to many use-cases. Mistral 7B is better than Llama 2 13B on all benchmarks, has natural coding abilities, and 8k sequence length. It’s released under Apache 2.0 licence. We made it easy to deploy on any cloud, and of course on your gaming GPU

Attempting to become your premiere search destination, the company released its own AI large language models (LLMs) — pplx-7b-online and pplx-70b-online, named for their parameter sizes, 7 billion and 70 billion respectively. They are fine-tuned and augmented versions of the open source mistral-7b and llama2-70b models from Mistral and Meta.

Open Source
Varun: “Why Open Source will win”: lengthy, detailed argument why LLMs are like Linux and have a fundamental long-term advantage over closed source.
Open source models are smaller and run on your own dedicated instance, leading to lower end-to-end latencies. You can improve throughput by batching queries and using inference servers like vLLM.
There are many more tricks (see: speculative sampling, concurrent model execution, KV caching) that you can apply to improve on the axes of latency and throughput. The latency you see on the OpenAI endpoint is the best you can do with closed models, rendering it useless for many latency-sensitive products and too costly for large consumer products.
On top of all this, you can also fine-tune or train your own LoRAs on top of open source models with maximal control. Frameworks like Axolotl and TRL have made this process simple5. While closed source model providers also have their own fine-tuning endpoints, you wouldn’t get the same level of control or visibility than if you did it yourself.
Technology Innovation Institute and startups MosaicML and Together are pushing forward their own open-source AI software.
Allen Institute has released OLMo, an open source language model. There are 7B and 1B parameter versions, and it claims performance better than similarly sized models. OLMo is the first completely open model: every step in development and every artifact generated is available.
Japan LLMs
Microsoft will invest almost $3B for Generative AI Accelerator Challenge (GENIAC), a program led by the Ministry of Economy, Trade and Industry which helps innovative startups and established enterprises develop foundation models as a core technology of generative AI in Japan.
- Large Language Model (EvoLLM-JP)
- Vision-Language Model (EvoVLM-JP)
- Image Generation Model (EvoSDXL-JP)
We are excited to release 2 state-of-the-art Japanese foundation models, EvoLLM-JP and EvoVLM-JP, on Hugging Face and GitHub (with EvoSDXL-JP coming up), with the aim of effectively accelerating the development of nature-inspired AI in Japan!

Eagle 7B is another new large language model. It claims to out-perform all 7B-class models while requiring the least computation power for inference. It is available on HuggingFace. While Eagle appears to be transformer-based, it claims to point the way “beyond transformers.”
