Anthropic / Claude Haiku 5.5
proDescription
Anthropic's small, fast model in the Claude 5.5 family, built for high-volume, latency-sensitive work. Haiku 5.5 is a large step up from Haiku 4.5 on reasoning, knowledge work, and computer use, and it is the first Haiku with adjustable effort. It reads text, images, and PDFs and holds a very large context. Suited to summaries, extraction, quick answers, and sub-agent tasks.
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 Haiku 5.5
proQuick Coding Tasks
Handles small fixes, code explanations, and sub-agent coding work alongside larger models. Anthropic recommends Sonnet or Opus for complex agentic coding, where Haiku 5.5 trails its bigger siblings.
First Haiku With Effort
The first Haiku model with an adjustable effort setting, defaulting to medium. Lower settings keep it fast and cheap, while higher ones let it think longer on harder questions.
Room For Long Inputs
A very large context window, shared with the rest of the Claude 5.5 family. Long documents, transcripts, and chat histories stay in view, which suits document question answering at volume.
Summaries And Extraction
Anthropic positions it for summaries, classification, extraction, and routing. Suited to fast, consistent structured output at high volume, rather than the most polished long-form writing.
Fast Knowledge Work
Anthropic reports a large jump over Haiku 4.5 on tests of real-world professional work. 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 Haiku 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.
