BONUS: GPT-6 Sol vs Claude Opus 5.5 LIVE: Which AI Model Is Better?

<p>GPT-6 Sol, GPT-6 Luna, AND Claude Opus 5.5 all just dropped. So which model should you actually use?</p><p><br></p><p>Join Grant Harvey and Corey Noles from The Neuron LIVE today as we put the newest models from OpenAI and Anthropic head-to-head.</p><p><br></p><p>OpenAI says GPT-6 Sol makes roughly half as many mistakes as GPT-5.6 Sol, bringing Astra-level reliability to a much cheaper model, while GPT-6 Luna is designed for fast, high-volume work like summarization, extraction, and quick questions. OpenAI is also dramatically cutting prices, with Sol reportedly coming in at $2 / $10 per million input / output tokens and Luna at just $0.10 / $0.50.</p><p><br></p><p>Meanwhile, Anthropic launched Claude Opus 5.5 just 90 minutes earlier. Anthropic says it performs around Claude Fable 5.1 level on most work while costing roughly 40% less to run than Opus 5, generating output more than 30% faster, and communicating more clearly. Its API price is $4 / $20 per million input / output tokens.</p><p><br></p><p>And the benchmark fight is already spicy: Anthropic reports Opus 5.5 scoring 66.4% on Terminal-Bench 4.0, 54.4% on FrontierCode, and 1,846 Elo on GDPval-AA v2.1, with particularly strong results in coding, computer use, and professional knowledge work.</p><p><br></p><p>On the livestream, we’ll break down:</p><p>⚔️ GPT-6 Sol vs. GPT-6 Luna</p><p>🤖 Claude Opus 5.5 vs. OpenAI’s newest models</p><p>💻 Coding, reasoning, writing, agents, and everyday work</p><p>💰 Pricing and what it means for AI users</p><p>🎯 Which model fits which kind of task</p><p>🧪 First reactions and live testing</p><p>💬 Your questions from the chat</p><p><br></p><p>If you’ve been wondering whether to use GPT-6 Sol, GPT-6 Luna, Claude Opus 5.5, or GPT-6 Astra, come hang out and test them with us.</p><p><br></p><p>🔴 LIVE: 3 PM CT / 1 PM PT</p><p><br></p><p>Subscribe to The Neuron newsletter: https://theneuron.ai</p><p><br></p><p>Models mentioned:</p><p><br></p><p>GPT-6 Sol + Luna: https://openai.com/index/introducing-gpt-6-sol-and-luna/Claude Opus 5.5: https://www.anthropic.com/claude-opus-5-5</p>
