UniLM
What is UniLM?
UniLM is a pre-trained language model from Microsoft Research that handles both natural language understanding and text generation from one shared Transformer. You fine-tune a single checkpoint for reading tasks like question answering and writing tasks like summarization or dialogue, without maintaining separate encoder-only and decoder-only models. Code and pretrained weights ship through the microsoft/unilm GitHub repo under an MIT license.
BERT-style models excel at reading but need a separate decoder stack for generation. UniLM trains one Transformer with three attention-mask modes: unidirectional, bidirectional, and sequence-to-sequence. That design let the same weights compete with BERT on GLUE and SQuAD while setting summarization and question-generation benchmarks in 2019, a split that most contemporaries treated as two problems.
ML researchers and NLP engineers use UniLM when they want published benchmarks, training scripts, and checkpoint files for both understanding and generation in one codebase. The repository now spans later releases like UniLMv2 (Pseudo-Masked Language Model, ICML 2020), but v1 remains the reference for the original unified masking approach described in the NeurIPS 2019 paper.
Gemini AI
What is Gemini AI?
Gemini is Google's flagship family of multimodal AI models, developed by Google DeepMind and available through the Gemini app at gemini.google.com. The models handle text, images, audio, and video in a single conversation, and the consumer app positions Gemini as a personal assistant for writing, planning, brainstorming, and research.
Google ships Gemini across several tiers, from the free Gemini app to paid Google AI Plus, Pro, and Ultra subscriptions. Developers access the same underlying models through the Gemini API in Google AI Studio, with separate free and pay-as-you-go pricing for production workloads.
The model line has expanded well beyond the original Ultra, Pro, and Nano sizes announced in 2023. Current releases include Gemini 3.5 Flash, Gemini 3.1 Pro, and specialized variants for image generation, video, audio, and on-device use.
