gpt-4-turbo over the API produces (statistically significant) shorter completions when it “thinks” its December vs. when it thinks its May (as determined by the date in the system prompt).
I took the same exact prompt over the API (a code completion task asking to implement a machine learning task without libraries).
I created two system prompts, one that told the API it was May and another that it was December and then compared the distributions.
For the May system prompt, mean = 4298
For the December system prompt, mean = 4086
N = 477 completions in each sample from May and December
t-test p < 2.28e-07

Mixtral of experts (via) Mistral have firmly established themselves as the most exciting AI lab outside of OpenAI, arguably more exciting because much of their work is released under open licenses.
On December 8th they tweeted a link to a torrent, with no additional context (a neat marketing trick they’ve used in the past). The 87GB torrent contained a new model, Mixtral-8x7b-32kseqlen—a Mixture of Experts.
Three days later they published a full write-up, describing “Mixtral 8x7B, a high-quality sparse mixture of experts model (SMoE) with open weights”—licensed Apache 2.0.
They claim “Mixtral outperforms Llama 2 70B on most benchmarks with 6x faster inference”—and that it outperforms GPT-3.5 on most benchmarks too.
This isn’t even their current best model. The new Mistral API platform (currently on a waitlist) refers to Mixtral as “Mistral-small” (and their previous 7B model as “Mistral-tiny”—and also provides access to a currently closed model, “Mistral-medium”, which they claim to be competitive with GPT-4. # 11th December 2023, 5:20 pm
When I speak in front of groups and ask them to raise their hands if they used the free version of ChatGPT, almost every hand goes up. When I ask the same group how many use GPT-4, almost no one raises their hand. I increasingly think the decision of OpenAI to make the “bad” AI free is causing people to miss why AI seems like such a huge deal to a minority of people that use advanced systems and elicits a shrug from everyone else.

Ice Cubes GPT-4 prompts. The Ice Cubes open source Mastodon app recently grew a very good “describe this image” feature to help people add alt text to their images. I had a dig around in their repo and it turns out they’re using GPT-4 Vision for this (and regular GPT-4 for other features), passing the image with this prompt:
“What’s in this image? Be brief, it’s for image alt description on a social network. Don’t write in the first person.” # 6th December 2023, 7:38 pm
