Gemini 4 Argon is out
Google shipped Gemini 4 Argon on Oct 13. It's Google's new frontier model for long, multi-step coding work like migrations. The API price starts at $2/M input and $10/M output tokens, and the input+output limit is 1M tokens. It's on the paid Gemini API tier, in AI Studio and Android Studio, and in Antigravity for AI Ultra subscribers.
⏱ 10-MIN TRYPick a messy file in a side project. Paste it into AI Studio with Argon and ask for a refactor plan. Then compare that plan with your usual model's.

ScaleDown's single-task models for agent loops
ScaleDown launched Constrained Decoding Models on Oct 13: Summarize, Compress, Extract and Classify. Each one only returns the answers its task allows, and each takes up to 1M input tokens. LangChain shipped `langchain-scaledown` middleware the same day. Extract and Summarize cost $0.04/M input tokens on OpenRouter. The speed and cost numbers come from the vendor and haven't been checked independently.
⏱ 10-MIN TRYRun `pip install langchain-scaledown`. Add the tool-result compression middleware to one Deep Agent, then compare token counts before and after.
