Mistral
Overview
Mistral is a family of efficient open and hosted models spanning edge deployment through frontier-scale multimodal workloads. Mistral 3 is the current generation.
Mistral AI launched Mistral 7B in September 2023 and followed it with the Mixtral mixture-of-experts models and hosted Small and Large tiers. Mistral 3, released in December 2025 under Apache 2.0, includes dense 3B, 8B, and 14B Ministral models plus Mistral Large 3, a 675B-parameter mixture-of-experts model with 41B active parameters.

Pythia
Overview
The most recent (as of May 2023) effort from EleutherAI, Pythia is a set of LLMs trained on The Pile. While it appears to outperform OPT and GPTNeo, its performance against GPT-J is unclear. Versions of Pythia have also been instruct-tuned by the team at Together.
