Added Claude Opus 5.5, GPT-6 Sol & Luna, Grok 4.7, and DeepSeek-V4.1-Flash
We have added five latest frontier models released in late September 2026 to our AI Model & API cost estimator.
■ Claude Opus 5.5 (Anthropic)
Features always-on Adaptive Thinking, delivering Fable 5.1-class performance at a significantly reduced price ($4 in / $20 out per 1M tokens).
■ GPT-6 Sol & GPT-6 Luna (OpenAI)
Expanding the GPT-6 generation with the balanced agent workhorse "Sol" ($2/$10) and the high-volume ultra-efficient "Luna" ($0.10/$0.50).
■ grok-4.7 (xAI)
xAI's latest frontier model optimized for coding and agentic tasks with a 500K context window and up to 450K output tokens.
■ DeepSeek-V4.1-Flash (DeepSeek)
Features native vision understanding and extreme cost-efficiency with off-peak rates down to $0.15/$0.60.
Compare their specs, run prompt caching simulations, and explore dedicated model detail pages now.
