Crazy 24 hours in AI model land

하이라이트

• Claude Opus 5.5 delivers higher intelligence across reasoning efforts at roughly 40% lower compute cost compared to Opus 5.

• Grok 4.7 is slow and burns through usage without offering noticeable intelligence gains over Grok 4.6.

• GPT-6 Sol operates as a cost-efficient upgrade to 5.6 Sol, but falls significantly short of GPT-6 Astra on complex reasoning tasks.

• GPT-6 Luna costs under 5 cents per task at maximum effort, making it ideal for high-volume, non-coding transformations.

• Xiaomi's MIMO 2.6 Pro beats Fable 5 on deep software engineering benchmarks despite taking 10 to 15 minutes of thinking time per task.

   Claude Opus 5.5 top performance and efficiency

   Benchmark comparisons show Opus 5.5 delivering superior reasoning capabilities while using less compute than previous iterations. This efficiency lowers the cost per attempt drastically compared to Fable. Additionally, outputs are formatted in cleaner, direct language without unnecessary fluff or excessive jargon.

   • Opus 5.5 outperforms GPT-6 Astra and Fable in intelligence benchmarks at a lower attempt cost.
   • Serving costs dropped by approximately 40% relative to Opus 5, allowing subscribers higher usage limits.
   • Anthropic tuned Opus 5.5 to eliminate jargon-heavy text in favor of concise English.

   Grok 4.7 speed and usage drawbacks

   Despite marginal improvements in software engineering benchmarks over version 4.6, Grok 4.7 suffers from severe performance bottlenecks. Real-world testing shows it burns through usage allocations rapidly while taking longer to process tasks. Until further optimizations occur, sticking with Grok 4.6 yields a better user experience.

   • Grok 4.7 wins only two benchmark categories and fails to lead in coding performance.
   • The model exhibits slow completion speeds and excessive token consumption.
   • Grok 4.6 remains the preferred choice over 4.7 due to identical pricing and superior operational speed.

   GPT-6 Sol cost efficiency versus intelligence limits

   OpenAI positioned GPT-6 Sol as a direct, cheaper replacement for 5.6 Sol within ChatGPT subscriptions. While it extends total subscription usage, it lacks the raw problem-solving power found in GPT-6 Astra or Opus 5.5. Users handling complex projects should prioritize higher-intelligence models rather than compromising for Sol's cost savings.

   • GPT-6 Sol provides higher intelligence and lower costs than GPT-5.6 Sol.
   • A substantial intelligence gap exists between GPT-6 Sol and top-tier models like Astra.
   • GPT-6 Sol suits lower-complexity day-to-day tasks rather than advanced agentic software design.

   GPT-6 Luna utility for non-coding workloads

   Log-scale benchmark displays obscure the value of GPT-6 Luna, which trades top-end coding ability for extreme affordability. At a fraction of Astra's operational expense, it handles high-volume tasks that do not demand frontier intelligence. It operates almost free of charge within subscription tiers and API integrations.

   • GPT-6 Luna costs under $0.05 per task at maximum effort compared to nearly $2.00 for Astra.
   • The model matches GPT-5.6 Sol intelligence at lower reasoning levels.
   • Luna serves as a low-cost engine for simple data reformatting and non-coding tasks.

   MIMO 2.6 benchmark strength and long thinking times

   MIMO 2.6 Pro delivers high-level reasoning for a tiny fraction of standard API costs, despite requiring long deliberation periods up to 15 minutes per task. While restricted regional subscription access limits broad adoption, developers can access it via OpenRouter. Its balance of low cost and high capability makes it an effective backend brain for custom AI agent applications.

   • Xiaomi's MIMO 2.6 Pro beats Fable 5 on deep software engineering benchmarks.
   • MIMO 2.6 Pro regularly spends 10 to 15 minutes processing problems before outputting results.
   • API pricing through OpenRouter makes MIMO 2.6 Pro an affordable option for custom coding agents.
