00:00Anthropic's new Opus 4.5 comes with Chrome and Excel integrations.
00:06Anthropic just dropped a new flagship model and claimed it's smarter, smoother, and somehow better at spreadsheets.
00:13Meet Opus 4.5, the final boss of Anthropic's 4.5 lineup, following the earlier arrivals of Sonnet 4.5 in September and Haiku 4.5 in October.
00:23This is the last in the series, like the season finale but with more benchmarks and fewer cliffhangers.
00:30As expected, Opus 4.5 immediately started collecting trophies.
00:34The model achieved top scores across various AI tests including coding, tool use, and problem-solving benchmarks, and became the first to score over 80% on SWE Bench Verified, a major achievement in AI coding performance.
00:49But Anthropic isn't just pitching Opus 4.5 as a smarter chatbot.
00:53They want it to be your new digital office assistant, one that never complains about meetings.
00:57The company is expanding Claude Access with Chrome and Excel tools to showcase Opus' capabilities.
01:04The Chrome extension will be available to all Macs users, while the Excel version will reach Macs, team, and enterprise customers.
01:11The real magic, though, is happening under the hood.
01:14Opus 4.5 features major memory upgrades for handling long conversations and massive documents.
01:20Instead of just stretching the context window, Anthropic focused on teaching the model what to remember.
01:26Diane Nepen explained that the model's memory must prioritize important details.
01:31This upgrade allows paid Claude users to enjoy an endless chat feature, where older conversation parts are compressed seamlessly without interruptions or context resets.
01:40All of this is especially important for Anthropic's vision of agentic AI, where Opus 4.5 acts like a project manager, coordinating a team of smaller haiku-powered sub-agents to tackle complex tasks.
01:53Think less chatbot, more AI middle manager who never sleeps.
01:58Still, it's entering a crowded battlefield, facing rivals like OpenAI's GPT 5.1 and Google's newly launched Gemini 3.
02:05The AI arms race continues, now with better memory and fewer dropped conversations.
