LLM cost planning autumn 2026: Sonnet 5 stays at $2/$10
Anthropic has cancelled the Claude Sonnet 5 price increase scheduled for 1 September 2026, making the introductory $2 input / $10 output per million tokens the permanent standard price. For teams running Claude on Azure through Microsoft Foundry, that removes a planned 50% jump from autumn budgets and reshapes the mid-tier price comparison against GPT-5.6 Terra and Gemini 3.1 Pro.
Tokens are the new pricing lever: Gemini 3.6 Flash math
Google's 21 July release of Gemini 3.6 Flash pairs an output-price cut from $9.00 to $7.50 per million tokens with a claim of roughly 17% fewer output tokens per task, compounding to about 31% lower output cost for unchanged work. That combination makes per-million-token price sheets unreliable for model comparison, and Azure teams should measure cost per completed task instead.
Gemini Enterprise Agent Platform vs Azure AI Foundry
Google's I/O 2026 enterprise announcements, led by the Managed Agents API, Gemini Spark and Gemini 3.5 Flash, take direct aim at Azure AI Foundry Agent Service and the Copilot ecosystem, down to launch connectors for SharePoint and OneDrive. For Azure-first Swedish and EU teams the decision rests on four questions: where the data lives, whether the cost claim survives real traces, whether audit obligations can be met, and what a second platform costs.
