OpenAI's flagship multimodal assistant powered by GPT-6 and GPT-5.6 for reasoning, coding, and deep research.
Automatically routes prompts or lets users select between Instant responses and Medium, High, or Extra High thinking depth across GPT-5.6 Luna, GPT-5.6 Sol, and flagship GPT-6 Pro/Astra models.
Asynchronous software engineering and task agents that clone repositories, run terminal tests in sandboxed environments, resolve complex bugs, and submit pull requests.
Browses dozens of primary web sources, academic papers, and connected workspace documents over several minutes to compile structured, citation-backed analytical reports.
Provides a split-screen editor for inline prose and code revisions alongside low-latency voice conversations with live screen and camera grounding.

Browser-based 3D design and animation with real-time team and AI agent collaboration
Model with primitives, booleans and sculpting, and use 3D generation to create objects from prompts.
Apply layered materials, lights and post-processing effects to give scenes a polished, production-ready look.
Build interactivity using states, keyframes, events and physics so scenes respond to scroll, hover and other triggers.
Connect AI coding agents to read, write and frame the live scene, then refine the same file by hand with your team.

Provides massive context windows and deep Google Workspace integration, but trails behind in advanced coding workflows.

Offers superior long-form writing and coding assistance with interactive artifacts, but lacks built-in deep web search.
Free / Open-sourceDelivers exceptional open-weight reasoning and math performance at lower cost, but features a simpler consumer interface.

Integrates real-time social media data and image generation directly into chat, but has fewer enterprise integrations.

SpecialistThe AI workspace where teams and agents get work done together
SpecialistExcels at real-time web research with verifiable inline citations, but offers less robust general conversational coding features.
Provides a completely free conversational assistant across social apps, but lacks advanced coding agents and deep research.

Generates 3D assets rapidly from text or images, but focuses on object creation rather than interactive web scene composition.

SpecialistThe AI coding agent for building ambitious software

SpecialistSpecializes in processing exceptionally long documents for deep research, but lacks multi-modal voice and advanced code execution.
Produces highly detailed 3D models from 2D references, but provides fewer interactive scene building and animation tools than Spline.
