Claims & numbers

• The presenter says he spent $3,000 in tokens over two weeks testing the newest frontier models [00:40].
• OpenAI released GPT-6 Sol and GPT-6 Luna two hours after Anthropic released Claude Opus 5.5 on the same day [01:21].
• Anthropic released Fable 5.1 and OpenAI released GPT-6 Astra roughly three weeks prior, three days apart [01:30].
• The presenter notes Claude Opus 4.6 was released 7 months earlier [03:23].
• A slide shown in Claude Design states Opus 5.5 costs $4 per million input / $20 per million output tokens (40% less than Opus 5), runs 30% faster, and won 7 of 9 internal Anthropic evaluation tests [07:10, 07:18].

Notable quotes

• "I've spent $3,000 in tokens over the past two weeks trying to test these new models, implementing these new tools in my business." [00:40]
• "The biggest, coolest thing that I've seen that this model is significantly better at is creating videos purely in code." [03:52]

Assessment
This is an independent creator review and hands-on demonstration of newly released models, tools, and consumer agent hardware. The live demonstrations of ChatGPT Voice interacting with Slack and Notion and Claude Opus 5.5 rendering code and design artifacts appear genuine and unedited, though footage from Meta Connect and external developer animations are sourced directly from keynote clips and social posts.
