Claude Haiku 4.5 vs GPT-5.4 Nano Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Anthropic / Claude Haiku 4.5
maxDescription
The fastest model in the Claude family, and the cheapest. Haiku 4.5 handles coding, analysis, and writing at speed, reads images and documents, and can show its reasoning when a task needs it. It holds less context than the larger Claude models, and its knowledge is about a year older. Built for volume and quick turnaround rather than the hardest problems.
OpenAI / GPT-5.4 Nano
proDescription
OpenAI's smallest and cheapest current-generation model, built for speed and volume. GPT-5.4 Nano excels at classification, data extraction, ranking, and coding sub-tasks, and works well as a fast sub-agent inside larger systems. It reads text and images, supports web search, and follows instructions reliably. Reasoning depth is shallow by design, traded for very low latency and cost at scale.

Why Use Claude Haiku 4.5 and GPT-5.4 Nano?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
Anthropic / Claude Haiku 4.5
maxLower-Cost Coding
Writes, debugs, and explains code across languages at a fraction of the cost of flagship models. Built for routine changes, quick fixes, and high-volume work. Complex refactors are where it reaches its limit.
Fast Reasoning
Extended thinking lets it work through multi-step problems and show its reasoning, without the wait a larger model would cost you. Solid on problems with a clear route to the answer.
Everyday Document Work
A 200,000-token context window, roughly 150,000 words. Enough for long reports, contracts, and code files. Ask questions across a full document without splitting it up.
Quick Writing & Drafting
Emails, summaries, documentation, and short-form content, returned fast. Output runs to 64,000 tokens in a single response, which covers most drafting work.
Everyday Research
Summarises and compares across the sources you give it. Its reliable knowledge cutoff is February 2025, so it knows less about recent events on its own than newer models.
Image & File Understanding
Text and images. Anthropic's documentation lists text and image input for all current Claude models. Audio and video input are not listed. Reads PDFs, spreadsheets, contracts, and code files.
OpenAI / GPT-5.4 Nano
proCoding Sub-Agents
OpenAI positions it for coding sub-tasks and as a fast sub-agent in multi-model architectures. Built for small, well-scoped jobs run at high frequency rather than whole engineering problems.
Adjustable Reasoning Effort
Reasoning effort ranges from minimal to 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 Inputs
A large context window, enough to classify or extract from big batches of text in a single pass. Ample for the high-volume work it is built for without splitting the input.
Extraction And Ranking
OpenAI names classification, data extraction, and ranking as its core uses. Built to process structured, repetitive text work quickly and cheaply rather than to write long-form content.
Web Search For Current Facts
Supports web search as a tool, so it can pull live information into an answer. Useful in background and real-time systems where the data needs to be current.
Text And Image Input
Reads text and images, so you can send screenshots or scanned pages alongside your prompt. Output is text only. Audio and video are not supported.
