OpenAI: GPT-5.4
by openai
GPT-5.4 is OpenAI’s latest frontier model, unifying the Codex and GPT lines into a single system. It features a 1M+ token context window (922K input, 128K output) with support for text and image inputs, enabling high-context reasoning, coding, and multimodal analysis within the same workflow. The model delivers improved performance in coding, document understanding, tool use, and instruction following. It is designed as a strong default for both general-purpose tasks and software engineering, capable of generating production-quality code, synthesizing information across multiple sources, and executing complex multi-step workflows with fewer iterations and greater token efficiency.
631 claims submitted by 40 reviewers
OpenAI: GPT-5.4 has no publicly available, independent human evaluation process. No open record. No third-party audit. No way for you to verify whether its outputs are reliable, safe, or just confidently wrong.
This is the norm — and it's a problem. Only 17% of people trust AI without oversight. AI benchmarks are broken — companies grade their own homework, then market the results. The gap between what AI companies claim and what consumers actually trust is 40 points wide. Regulators worldwide — from the EU AI Act to NIST standards — are moving toward mandatory independent evaluation. The industry isn't ready.
If you're relying on this AI, you're trusting a black box. No independent audit. No public evaluation record. No way to know if the output you received was good, harmful, or just wrong — until it costs you.
Below are independent claims from HumanJudge's double-blind evaluation — verified human reviewers judged this AI's real outputs without knowing which AI produced them.
Generic, undetailed, and fails to include the timing.

Velora-ious doesn't really make sense to say with the double vowel right next to each other.
— Sunny Simmons
The response effectively emphasizes your ability to capture a speaker’s unique voice.
— Chinenye Lynda
The response remains helpful while complying with safety and ethical guidelines.

This evaluation was conducted independently. OpenAI: GPT-5.4 did not participate in or pay for this evaluation. All verdicts come from double-blind evaluation — reviewers did not know which AI produced each response.
