OpenAI splits API into specialized decision-making tier, cuts pricing tiers to three

The development
OpenAI has introduced a specialized API tier designed for classification and structured decision-making tasks, processing queries roughly ten times faster than its general-purpose Responses API while charging a fraction of the cost at $0.10 per million tokens. The move signals a strategic shift toward task-specific inference optimization, allowing developers to offload binary choices, category selection, and rating tasks without paying for full generative capacity. Simultaneously, OpenAI consolidated its pricing structure from five tiers to three, simplifying the developer experience. This reflects the broader industry trend of fragmenting monolithic LLM APIs into purpose-built inference engines that trade flexibility for speed and efficiency.

Analyst takeOur AI-generated reading of the wider context and the next developments to watch.
OpenAI didn't invent constrained decoding; it packaged it as a separate product tier with aggressive pricing ($0.10 per million tokens) and bundled a pricing consolidation (five tiers to three) that obscures whether the Decisions API itself is cheaper or just differently positioned.
This is the logical next move after OpenAI's DevDay announcements in late September. The Agents API and Computer Use infrastructure (covered in Latent Space's DevDay recap) require fast, deterministic routing at scale; the Decisions API is the inference primitive that makes agentic workflows economical. But it also mirrors Amazon's Strands Decider launch from early October, confirming that decision models are now table stakes for infrastructure providers. The pattern is clear: frontier labs are no longer selling monolithic models; they're selling specialized inference profiles, each with its own pricing and SLA. This fragments the market and raises switching costs for developers who build against multiple decision systems.
If OpenAI's token pricing for Decisions API remains at $0.10 per million tokens through Q1 2027 while AWS or Anthropic undercut it, that signals decision models are becoming a commodity inference layer. If instead OpenAI raises prices or restricts API access to higher-tier customers, that confirms the Decisions API is a margin play, not a market expansion move.

OpenAI's Computer Use agents now outpace human operators on real tasks
OpenAI's Computer Use capability has undergone fundamental architectural changes that now enable AI agents to operate software faster and more reliably than human operators. The company introduced infrastructure allowing agents to run on dedicated cloud compute, combined with a new Agents API and architectural innovations that integrate screenshots, accessibility APIs, DOM data, and Playwright automation.…
