OpenAI Launches GPT-5.5 to Challenge Anthropic’s Claude Opus 4.7
OpenAI launched GPT-5.5 on April 23, codenamed “Spud,” positioning the mannequin as its most succesful system for autonomous, multi-step work.
The launch arrives one week after Anthropic shipped Claude Opus 4.7, establishing a direct comparability between the 2 frontier fashions.
GPT-5.5 Targets Agentic Work and Coding
GPT-5.5 is constructed to plan, execute, confirm, and iterate throughout instruments with out fixed human oversight. OpenAI describes it as “a brand new class of intelligence for actual work and powering brokers.”

“We consider in iterative deployment; though GPT-5.5 is already a wise mannequin, we count on speedy enhancements. Iterative deployment is a giant a part of our security technique; we consider the world can be finest outfitted to win on the workforce sport of AI resilience this manner,” wrote Sam Altman in a submit.
The mannequin rolls out now to ChatGPT Plus, Pro, Business, and Enterprise customers. A extra highly effective Pro variant can also be accessible. API pricing begins at $5 per million enter tokens and $30 per million output tokens with a one-million-token context window.
OpenAI’s personal benchmarks present GPT-5.5 forward of Claude Opus 4.7 on several agentic tasks. It scored 82.7% on Terminal-Bench 2.0, in contrast to 69.4% for Opus 4.7.
On FrontierMath Tiers 1 by way of 3, it reached 51.7% versus 43.8%. Early impartial checks reported related traits in coding and knowledge-work evaluations.
Where Claude Opus 4.7 Still Leads
Anthropic’s model retains advantages in analysis writing, authorized and monetary reasoning, and instruction-following consistency, in accordance to impartial reviewers.
Opus 4.7 additionally helps higher-resolution imaginative and prescient at up to 3.75 megapixels, greater than thrice its predecessor.
On pc use, the hole narrows. GPT-5.5 scored 78.7% on OSWorld-Verified, whereas Opus 4.7 posted 78.0%.
The two fashions additionally trade leads on browsing benchmarks, with GPT-5.5 Pro pulling forward at 90.1% versus 79.3%.
AI Race Accelerates in 2026
The back-to-back launches replicate a broader sample. OpenAI has shipped a number of GPT-5.x variants this 12 months, whereas Anthropic has steadily upgraded Claude by way of successive releases.
Google’s Gemini 3.1 Pro additionally competes for the same enterprise market.
For builders selecting between the 2, the choice might come down to use case. GPT-5.5 seems stronger for agentic automation and long-horizon coding.
Claude Opus 4.7 might swimsuit precision-heavy analytical workflows better. Whether impartial benchmarks verify OpenAI’s printed numbers will develop into clearer within the days forward.
