Overview
GPT-5.4 vs Claude Haiku 4.5 Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
OpenAI / GPT-5.4
maxDescription
OpenAI describes GPT-5.4 as its more affordable model for coding and professional work. It carries OpenAI's top reasoning rating, a million-token context window, and web search. The trade is speed and freshness: it runs at medium speed and its knowledge stops in August 2025. Strong value when the work is hard but not urgent.
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.

Why Use GPT-5.4 and Claude Haiku 4.5?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
OpenAI / GPT-5.4
maxAffordable Frontier Coding
OpenAI positions this squarely as its cheaper route into complex coding and professional work. Handles large codebases and multi-step engineering tasks with reasoning effort you can push from none up to xhigh when a problem demands it.
Better Reasoning at Lower Price
OpenAI rates its reasoning Highest, the top of the company's own scale, at half the price of its newest frontier model. Reasoning tokens are supported, and effort defaults to none, so you decide when the model thinks hard.
One Million Context Tokens
A 1,050,000-token context window. Load a full codebase, a research corpus, or a large document set and work across all of it in one session. Prompts above 272,000 input tokens are billed at a higher rate.
Extended Professional Writing
Writes up to 128,000 tokens in a single response, enough for long reports, complete documentation sets, and extended technical writing without breaking the job into parts.
Web Search Support
Web search is a supported tool, so it can ground answers in live sources. Its knowledge cutoff is 31 August 2025, which is older than most frontier models, so recent events genuinely need that search rather than merely benefiting from it.
Reads Text and Images
Text and image input, text output. OpenAI's documentation states plainly that audio and video are not supported. File search is supported, so it can work across uploaded documents.
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.
