GPT-5.6 Sol 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 Sol
maxDescription
OpenAI's flagship and the top tier of the GPT-5.6 family. Sol is built for the hardest professional work: complex coding, extensive research, computer use, and scientific work. It reads text and images across a very large context, supports web search, and its knowledge is among the most recent in the catalog. Reasoning effort can reach the highest levels for the most demanding problems. Priced at the top of OpenAI's range, and built to earn it.
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 Sol 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 Sol
maxFrontier Agentic Coding
OpenAI positions Sol as its strongest model for coding and agentic work, achieving state-of-the-art results on terminal and real codebase benchmarks. Built for long, multi-step engineering that runs across many tool calls.
Reasoning To Highest Effort
Reasoning effort ranges from low to high, defaulting to high for the hardest problems. OpenAI reports it reaching top results while using fewer tokens than comparable models, so depth need not mean waste.
Room For Whole Projects
A very large context window, among the largest available. Load an entire codebase, a full research corpus, or a large document set and work across all of it in one request without chunking.
Professional Knowledge Work
OpenAI builds it for difficult professional work across science, research, and design, as well as coding. Suited to output that has to be right the first time rather than merely drafted.
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 supported.
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.
