GPT-5's router directs queries based on complexity and intent, helping OpenAI allocate compute across low-value informational and high-value commercial requests
To many power users (Pro and Plus), GPT5 was a disappointing release. But with closer inspection, the real release is focused …

Context & Ripple Effects
OpenAI had already framed GPT-5 as a unified system combining an efficient model, a reasoning model, and a router that chooses between them. This report adds the operational rationale: routing is not only about matching a model to a task, but also about distributing scarce compute across request types.
That helps explain why Pro and Plus users can judge the release differently from its underlying architecture: the visible answer is the output of a routing policy as well as a model.
First-order effects
GPT-5 can direct low-complexity and low-value informational requests toward less costly handling while reserving more compute for harder or commercially valuable requests.
Pro and Plus users are immediately affected by the router’s classifications: their perceived GPT-5 quality can vary with request complexity and intent, not simply with the model name.
Second-order effects
User dissatisfaction becomes feedback on routing policy as well as model capability, making it harder to infer product quality from a single benchmark or usage anecdote; subsequent coverage of underwhelming GPT-5 benchmarks underscores that distinction.
The router becomes a central operating lever for balancing service quality and compute use, rather than a background feature that merely selects a model.
Third-order effects
If this approach persists, frontier-model competition will increasingly hinge on orchestration—deciding which workload receives which level of inference—not solely on improving one general-purpose model.
Intent-sensitive compute allocation could make access tiers and request classification more consequential parts of AI product design, with users evaluating consistency as closely as peak capability.
The trend: AI platforms are evolving from single-model products into routing control planes that allocate expensive reasoning capacity by task value and complexity.
This is completely fantastical, total nonsense, based on guesswork. From everything I've found OpenAI's gpt-5 router is more expensive and compute intensive. Even this bit about the supposed genius of Fidji Simo, the new ceo of apps, is just writing up her LinkedIn [embedded po…
GPT-5 has been hyped for years as the next step towards AGI. Sam Altman promised a “PhD-level intelligence on any topic.” It's not even close. — On the terms OpenAI itself laid out for its own product, any fair assessment must conclude that GPT-5 is a failure. — Now the que…
Are you ready for OpenAI to unleash the monetization slop upon the masses? The real release of GPT-5 was the router and how they can reduce cost / compute for most users by routing to cheaper models. Open has a big strategic shift in the works, and consumer purchasing will shift.

so if you can't tell i wrote the F outta this also i know we are getting a lot of pushback, but the affiliate model feels inevitable timeline is this Instacart adopts agentic purchase in Jan Instacart CEO leaves to OAI in may Sama tone shift Router for control of query ?????
Updates to ChatGPT: You can now choose between “Auto”, “Fast”, and “Thinking” for GPT-5. Most users will want Auto, but the additional control will be useful for some people. Rate limits are now 3,000 messages/week with GPT-5 Thinking, and then extra capacity on GPT-5 Thinking
Paying users are getting GPT-4o back after lots of users complained that GPT-5 is a downgrade. — It's so weird to me that some set of these complaints are about the “personality” of the new model and not its functionality. — The software game has changed, man.
Gmail, Google Calendar, and Google Contacts are now available to connect and use in chat for ChatGPT Pro users where ChatGPT will automatically reference them when relevant, beginning to roll out globally this week followed by Plus, Team, Enterprise, and Edu plans in the coming […
Yess! Finally! ChatGPT (at least for pro) have just enabled the Gmail connector for chat, not only deep research! 🔥 This + Goog Cal integrations are now enabled by default in chats [image]
