Claude Opus 5 Is Anthropic's Current Premium Opus Model
Anthropic lists Claude Opus 5 as active with a 1M-token context window, up to 128K output tokens, and standard API pricing of $5 input and $25 output per million tokens.
Why it matters: Treat Opus 5 as a current premium option to evaluate for difficult reasoning and agent workflows, not an automatic winner in every editorial category.
GPT-5.6 Introduces Sol, Terra, and Luna
OpenAI released the GPT-5.6 family on July 9, 2026: Sol as the flagship model, Terra as the balanced option, and Luna for lower-cost, latency-sensitive work.
Why it matters: The meaningful decision is no longer one GPT tier. Choose the model lane that matches your workflow and budget, then validate the actual product limits before committing.
ChatGPT Plans Now Surface GPT-5.6 Access by Tier
The current ChatGPT plan page lists limited GPT-5.5 Instant access on Free, GPT-5.6 advanced reasoning on Plus, and GPT-5.6 Sol Pro on Pro.
Why it matters: Plan pages change more often than model announcements. Treat subscription copy as a dated snapshot and check the official matrix before purchasing.
Gemini 3.6 Flash Leads Google's Current Balanced Model Line
Google documents Gemini 3.6 Flash as its most balanced model for speed and intelligence, with Gemini 3.5 Flash and Flash-Lite covering sustained agentic and lower-cost workloads.
Why it matters: For API buyers, the useful comparison is workload fit and standard token price, not a universal model ranking.
