GPT-6.1 Terra launched on 26 October 2026 at $1 per million input tokens and $5 per million output tokens, half of GPT-5.6 Terra's input price and well under half of its $12 output price. The list price is only the starting point. Three things

OpenRouter and AIHubMix are both one-key gateways to more than 500 models, and on Claude, GPT, Gemini and Grok they charge the same per-token price: the vendor's list price. So the comparison isn't about the sticker price. It's about what you pay

Three cheap coding models shipped within four weeks of each other: DeepSeek V4.1 Flash (with its 1017 update), Claude Haiku 5.5, and MiniMax M3.1 Flash, which spent its first week as the anonymous Space Bunny. All three have a 1M-token context window and cost between $0.

DeepSeek's lineup has an odd shape this autumn. V4 Pro 0813 is the bigger, pricier model: at peak hours its output costs $3.96 per 1M tokens, 3.3 times the Flash's $1.20. But the Flash has been retrained twice since Pro's August
