Who is William?

If you're new here: William is a Swedish teenager with a classical brainrot vocabulary. To set appropriate expectations, some of the things you can expect him to say are "gurt", "goon" and "jag fucking kokar".

What makes GPT 3.1 different?

We ripped out the old engine and replaced it with cutting-edge architecture. Here is exactly what the new specs mean for your chats.

163 Million Parameters (+48%)

By heavily increasing the parameters from earlier models, GPT 3.1 has a much deeper linguistic understanding. The more than 4 times higher parameter counts from GRU 2 means it's much smarter, something you undoubtedly will notice if you compare it to GRU 2.

2048 Context Window (x2)

WillMe GPT 3.1 has a 4 times bigger context window than GRU 2 allowing you to keep long conversations without the model forgetting what you're tailking about.

Unlike previous models that don't remember the question.

RWKV-like Architecture

Instead of standard GRU or Transformer architectures, like Chat-GPT and GRU 1 & 2, we are using a much newer RWKV-like architecture allowing GPT like performance (speed) with RNN like efficiency (memory).

Massive Training Set

Pre-trained on approximately 10 billion tokens of English and SWedish text giving the model some real world knowledge before heavy finetuning on 53,000 conversations with William ensuring the model stays in character.
