DeepSeek announced on September 10 that V4 Pro would be retired today at 04:00 UTC. Instead, they reversed course in response to user demand, keeping V4 Pro live at unchanged pricing. Here is what the two-model landscape now looks like and which workloads belong on which.
DeepSeek V4.1-Flash ships today under a new API name with native multimodal. On September 14, every deepseek-v4-pro request silently reroutes to V4.1-Flash at Flash pricing. Here is what the capability delta means and what to pin before the deadline.
Priority Processing is now Fast mode, GPT-5.6 Luna costs 80% less, Terra 20% less — and a ramp rate limit means your batch jobs could silently downgrade to standard speeds.
OpenAI cut GPT-5.6 Luna 80% and Terra 20% on July 30, while renaming Priority Processing to Fast mode. Luna at $0.20/$1.20 per 1M tokens now competes directly with DeepSeek V4 Flash and Qwen models. Here is the routing tier math every operator must recalculate.
Alibaba Cloud Bailian cut the GLM-5.2 Fast mode token price by 20% on July 15. For operators routing cost-sensitive workloads through DashScope's OpenAI-compatible endpoint, the math just changed.
Claude Sonnet 5 launches at $2/$10 per million tokens through August 31—then moves to $3/$15. The model replaces Sonnet 4.6 as Anthropic's default and brings Opus-class agentic performance at Sonnet pricing. Here's how routing teams should respond.
Starting July 1, 2026, Google's Gemini 3 and later models charge a 10% premium on non-global (regional) endpoints. Teams routing to eu-west1, asia-northeast1, or other non-global locations must audit their cost models today.
Fable 5 returned June 18 with nationality-based access controls, tighter safety classifiers, and mandatory data retention. Today is the last day it's included in subscriptions — from June 23, credits are required at $10/M input and $50/M output tokens.
GitHub Copilot's June 1 token-billing switch is landing real bills — some users report projected costs of $754–$847/month vs. a prior $39–$44 flat rate. This is what the May 2026 pricing shift looks like in production, and why routing architectures matter.
DeepSeek V4 Pro's 75% price cut is now permanent — $0.87/M output tokens with 80%+ SWE-bench scores. Here's why it shifts V4 Pro from premium fallback to primary reasoning tier and what that means for your routing cost structure.
Gemini 2.0 Flash and Flash-Lite hit end-of-life June 1, 2026 — the shutdown is done. Here is what model IDs were removed, which replacements (gemini-2.5-flash-lite, gemini-3.1-flash-lite) actually work as substitutes, the real cost delta, and the fastest way to audit…
Gemini 3.5 Flash launched at $1.50/$9 per million tokens — up to 6x the cost of earlier Flash models — and the new Interactions API changes how routing teams should handle Gemini Flash fallbacks and session continuity.
