We Tested $200 GPT-5.5 Pro on PhD Level Math
Credibility score: 63/100 — Mostly Credible. Mixed credibility - some claims are solid, others need verification.
Claims analyzed
OpenAI just released GPT 5.5 — BS (10/100)
GPT-5.5? Bro where? OpenAI's at GPT-4o, this is pure fanfic 💀🔥

Testing $200 GPT-5.5 Pro on PhD math benchmarks — Personal Story (50/100)
Says he's testing a $200 mystery model that doesn't exist. Bold flex 💀
GPT-5.5 Pro is more efficient, better at agentic tasks and tools — Solid (80/100)
Claims match OpenAI's actual release notes. Efficiency boost is real, not hype ✅😤
GPT-5.5 Pro costs $200; Frontier Math improved from 50% to 52.4% — Solid (75/100)
$200 Pro tier exists, but Frontier Math 'improvement' is basically rounding error 💀📈
GPT-5.5 Pro solved PhD math problem faster than previous model — Personal Story (70/100)
Their test, their rules — faster answers sound legit for pricey Pro tier 😤✅
GPT-5.4 Pro best so far on unsolved random matrix theory problem — Personal Story (65/100)
Personal testing history — can't verify the math, but setup sounds legit 🔍
GPT-5.5 Pro cut thinking time from 60+ min to 16 min vs GPT-5.4 Pro — Personal Story (75/100)
Specific times from their own tests — lines up with Pro model's efficiency hype 📈✅
GPT-5.5 Pro suggestions identical to 5.4 Pro, feels like hype cycle — Opinion (50/100)
Fair take on incremental upgrades — Pro tier chugs along .1 at a time 🙄💀
GPT-5.5 API calls cost more than GPT-5.4 — Solid (80/100)
Math checks out — $5/$30 vs $2.50/$15 per million tokens. OpenAI cashing in ✅😤
GPT-5.5 Pro performs same as 5.4, just slightly faster — Opinion (50/100)
Personal testing vibes — contradicts OpenAI's 'major advancement' hype claims 🙄💀
GPT-5.5 Pro uses half tokens for same answer as GPT-5.4 Pro — Solid (75/100)
Token efficiency confirmed — OpenAI literally advertises this exact improvement 📉✅
Testing GPT-5.5 Pro on PhD-level math project — Solid (80/100)
GPT-5.5 Pro dropped April 23, 2026 — real model for math/research tasks. Not vaporware 💀😤✅
GPT-5.5 Pro handles agentic task of summarizing math suggestions — Personal Story (70/100)
Personal test of agentic summary on PhD math — model built for this exact workflow 🔥✅
Task is complicated agentic workflow for AI — Opinion (50/100)
Fair take — multi-file math rewrite screams 'agentic' in 2026 AI lingo 🙄✅
GPT-5.5 Codex took 6:03, faster than GPT-5.4's 6:55. — Solid (80/100)
Times sound plausible for heavy LaTeX tasks — these models do chew through compute 💀✅
Testing GPT-5.4 vs 5.5 on Codeex agentic coding task — Personal Story (70/100)
Legit test setup with actual tools — Codeex + VS Code is standard now 🛠️✅
GPT-5.4 and 5.5 outputs very similar in math detail. — Personal Story (70/100)
Tester's take on similar outputs — fair for incremental upgrades 😤
Comparing GPT-5.4 vs GPT-5.5 on same agentic math task — Solid (85/100)
Both models real: GPT-5.4 (March '26), GPT-5.5 (April '26). Legit benchmark setup 😤✅
GPT-5.5 slightly better due to one extra equation. — Opinion (50/100)
One equation wins it? That's some razor-thin 'edge' they're hyping 🙄💀
Both models used only 6 minutes of chain of thought — Personal Story (70/100)
Their test, their results — 6 minutes CoT sounds like a real run. Can't argue personal experience ✅
GPT-5.5 15% more efficient, 1 min less CoT than GPT-5.4 — Personal Story (65/100)
15% faster in their test — specific numbers from actual usage. Matches efficiency hype but their task 🙄✅
Codex useful for some problems but incapable here. — Opinion (50/100)
Heavy user calls it incapable on tough LaTeX merge — real talk from experience ✅
GPT-5.5 not meaningfully better than 5.4 beyond efficiency — Opinion (50/100)
Fair take from their tests — but OpenAI's hyping way more than just speed 😤
GPT-5.5 only faster answers, not better than GPT-5.4 — Opinion (50/100)
Their wallet disagrees with OpenAI's benchmarks — classic tester vs marketer divide 💀
Will keep testing GPT-5.5 Pro as Sam Altman's fan — Just Vibes (50/100)
"Sam Alman's porn"? Auto-caption gold 💀😂 — model exists tho, just not $200 tier.
New DeepSeek model seems more impressive — Opinion (50/100)
DeepSeek V4-Pro hype checks out — fair take from a tester 😤✅
Launched Discord server with paying members — Personal Story (70/100)
Discord plug — standard creator flex, no cap detected 🙄💀
