GPT 5.5

Compared to a frontier model like GPT 5.5, it's about 65x cheaper to run, and for a lot of what we actually use LLMs for

delivering performance that rivals Opus 4.8 and GPT 5.5

rival GPT 5.5. But these are strange times and my April prediction

orchestrate cheaper models like Codex and GPT-5.5

I’m not convinced it should replace Opus or GPT-5.5 yet.

I tested Claude Opus 4.8, GPT-5.5, and Gemini 3.5 Flash on 10 World Cup 2026 predictions

Full tier list inside: Fable 5 (S+), Opus 4.8 / GPT-5.5 (S), GLM-5.2 / Qwen Max / Gemini 3.1 Pro / DeepSeek Pro (A)

Claude 5 (Fable) scored 65 on the AA Intelligence Index — beating GPT-5.5

closed frontier models like Opus 4.8 and GPT 5.5 across benchmarks

GLM-5.2, a brand new free AI from China, just shook up the entire industry. In blind tests it ranked the second best mod

Swap Fable for Opus, swap Opus for GPT 5.5

they even name uh GPT 5.5

including OpenAI's GPT-5.5, can already do

Opus 4.8 and GPT-5.5 have been two of the leading coding models

Composer 2.5 vs Opus 4.7 vs GPT 5.5 — all given the exact same prompt inside Cursor

GPT 5.5 kept looking stronger when the task needed detail, debugging, and follow-through.

What is better than one GPT-5.5 Pi coding agent? Two.

We run the exact same destructive prompts side-by-side against Claude Code with Opus 4.7 and the Pi coding agent with GP

Dive into advanced features like accessing GPT 5.5, personalization and agents.

Opus 4.7 builds and GPT 5.5 verifies completely unprompted

GPT-5.5 is here, and I tested it across research, coding, Codex, GPT Image 2 asset workflows
