- Incorporates Sliding Window Attention (window size 128 tokens) and Attention Sinks for computational efficiency, long-range dependencies, and stability.
- Utilizes Rotary Position Embeddings (RoPE) enhanced with YaRN scaling for extended context handling.
- Model variants include
gpt-oss-120b(117B total parameters, 5.1B active, designed for high reasoning tasks on a single H100 GPU) andgpt-oss-20b(21B total parameters, 3.6B active, optimized for lower latency and local deployment).
- ChatGPT Atlas (OWL Architecture): A web browser where the LLM functions as a co-pilot across the internet.
- Employs OpenAI's Web Layer (OWL), an architectural layer that runs Chromium's browser process outside the main Atlas application process.
- Communication between the Atlas client (OWL Client) and the Chromium browser process (OWL Host) is facilitated via Mojo, Chromium's message-passing system.
- Custom Swift and TypeScript bindings for Mojo enable the Swift-based Atlas application to directly call Chromium functions.
- The user interface of Atlas is a comprehensive rebuild using modern native frameworks like SwiftUI and AppKit, decoupling it from the Chromium rendering engine to allow for rich animations and visual effects.
