Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Anthropic / Claude Sonnet 5.5
proDescription
Anthropic's Sonnet model in the Claude 5.5 family, built for fast, well-scoped everyday work. Sonnet 5.5 improves on Sonnet 5 across coding, writing, and knowledge work, and often finishes the same task in fewer steps. It reads text, images, and PDFs, holds a very large context, and reasons with adjustable effort. Anthropic highlights its clearer writing and its sharp eye for design.
OpenAI / GPT-5 Nano
lightDescription
OpenAI's smallest and cheapest GPT-5 model, built for speed above all. GPT-5 Nano is made for summarisation, classification, and other well-defined tasks that run at high volume. It reads text and images, with adjustable reasoning effort. Reasoning depth is shallow by design and its knowledge is dated. The trade is cost: it is among the cheapest models in the catalog.

Anthropic / Claude Sonnet 5.5
proFast Everyday Coding
Anthropic reports its biggest gains over Sonnet 5 in coding, with strong results on real-world agentic coding tests. Early testers note how fast it understands a codebase and batches tool calls into fewer steps.
Effort You Can Adjust
Reasoning effort runs from low to max, defaulting to medium in Anthropic's apps. Anthropic reports that its lower settings already beat Sonnet 5's best results on several tests, for far less work per task.
Room For Whole Projects
A very large context window, shared with the rest of the Claude 5.5 family. Load a full codebase or a long document set and work across it in one conversation without splitting it up.
Polished Documents And Slides
Anthropic highlights clearer writing and a sharp eye for design. It creates documents, slides, and spreadsheets that need little editing, and it can follow a slide template closely.
Professional Knowledge Work
Anthropic reports results close to Opus-level on tests of real-world work across many occupations, including long-horizon research. It has no native web search, so current data comes through connected tools.
Text And Image Input
Anthropic lists text and image input for all current Claude models, and Sonnet 5.5 reads screenshots, charts, and PDFs. Output is text only. Audio and video are not supported.
OpenAI / GPT-5 Nano
lightCoding Sub-Tasks
Suited to small, well-scoped coding jobs and to acting as a fast sub-agent inside a larger system, rather than tackling whole problems. Reasoning depth is limited, so keep the scope tight.
Adjustable Reasoning Effort
Reasoning effort runs from minimal through low, medium, and high. Even at higher effort it is a shallow reasoner by design, so it suits speed-sensitive work rather than hard multi-step problems.
Room For Long Documents
A large context window, enough to summarise long reports or classify big batches of text in a single pass without splitting the input into separate requests.
Summarisation And Classification
OpenAI names summarisation and classification as its core uses. Built to process high volumes of text quickly and cheaply rather than to produce polished long-form writing.
Analysis On Older Knowledge
Its training data is dated by current standards, so it is fine for processing text you supply but weaker on recent events, which need live sources rather than the model's own knowledge.
Text And Image Input
Reads text and images, so you can send screenshots or scanned pages alongside your prompt. Output is text only. OpenAI states audio and video are not supported.
