Title: OpenAI Unveils Coding-Focused GPT-4.1 While Phasing Out GPT-4.5

OpenAI unveiled its GPT-4.1 model family on Monday, prioritizing coding
capabilities and instruction following while expanding context windows to 1
million tokens -- approximately 750,000 words. The lineup includes standard
GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano variants, all available via API but
not ChatGPT. The flagship model scores 54.6% on SWE-bench Verified, lagging
behind Google's Gemini 2.5 Pro (63.8%) and Anthropic's Claude 3.7 Sonnet
(62.3%) on the same software engineering benchmark, according to TechCrunch.
However, it achieves 72% accuracy on Video-MME's long video comprehension
tests -- a significant improvement over GPT-4o's 65.3%. OpenAI simultaneously
announced plans to retire GPT-4.5 -- their largest model released just two
months ago -- from API access by July 14. The company claims GPT-4.1 delivers
"similar or improved performance" at substantially lower costs. Pricing
follows a tiered structure: GPT-4.1 costs $2 per million input tokens and $8
per million output tokens, while GPT-4.1 nano -- OpenAI's "cheapest and
fastest model ever" -- runs at just $0.10 per million input tokens. All
models feature a June 2024 knowledge cutoff, providing more current
contextual understanding than previous iterations.
