GPT-5.6 Terra vs Claude Opus 5.5 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-5.6 Terra
maxDescription
OpenAI's balanced everyday model in the GPT-5.6 family, and its new default GPT for most work. Terra delivers roughly the quality of the previous flagship at about half the cost, with strong coding, agentic work, and design sense. It reads text and images across a very large context, supports live web search, and lets you set reasoning effort per request.
Anthropic / Claude Opus 5.5
maxDescription
Anthropic's newest flagship, and the first in its Claude 5.5 family. Anthropic positions Opus 5.5 to perform at the level of its most capable model on most work, while costing meaningfully less to run than the previous Opus. It reads text and images, holds a very large context, and reasons before every answer with adjustable effort. Anthropic calls it their daily driver for serious coding, computer use, and knowledge work, with its knowledge current to mid-2026.

Why Use GPT-5.6 Terra and Claude Opus 5.5?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
OpenAI / GPT-5.6 Terra
maxCoding With Design Sense
OpenAI tuned this generation for front-end taste, producing tasteful, functional interfaces from high-level direction. It can inspect the rendered result and refine it, rather than emitting code and hoping it works.
Reasoning Effort You Set
Reasoning effort runs from none through low, medium, high, and higher settings, so you control how hard the model works per request. OpenAI positions Terra as the balanced baseline for most API work.
Room For Whole Projects
A very large context window, big enough to hold a substantial project in view so the model stops losing track of files across a long build. Prompts above a high threshold are billed at a higher rate.
Professional Knowledge Work
OpenAI positions the family for professional knowledge work, science, and design alongside coding. Terra suits that work at a cost that makes running it at volume practical rather than reserved for the hardest tasks.
Web Search And Recent Knowledge
Supports web search as a tool, and its knowledge is among the most recent in the catalog. Together those cover current questions well, with the search filling anything past the training cutoff.
Text And Image Input
Reads text and images in the same prompt, so you can send screenshots, diagrams, or scanned pages alongside your question. Output is text only. Audio and video are not accepted.
Anthropic / Claude Opus 5.5
maxDaily-Driver Coding
Anthropic positions it as its everyday model for serious coding and agentic work, reaching its most capable model's level on most tasks. Built for real software engineering across many steps rather than isolated snippets.
Adaptive Thinking Always On
Reasoning is always on, with an effort dial rather than an off switch, defaulting to medium. Anthropic reports medium effort here, matching the previous Opus at high, so it thinks efficiently rather than at length.
Room For Whole Projects
A very large context window with no smaller default. Anthropic reports stronger long-context management, so instruction following and reasoning hold across a full codebase or a long agent run.
Precise Document Work
Anthropic's strongest Opus for vision and document work: dense filings, charts, screenshots, and diagrams read at high fidelity. It also writes more concisely than the previous Opus, a deliberate change.
Deep Computer Use
Anthropic reports that its best Opus is for computer use, handling multi-step tasks that span several applications and require planning and judgment. Suited to agentic work that operates real software, not just answering questions.
Text And Image Input
Reads text, images, and PDFs in the same prompt, so you can send screenshots, filings, diagrams, or charts alongside your question. Output is text only. Audio and video are not accepted.
