OpenAI's Decisions API Is Now Live for Everyone — and It Was Built to Catch a Startup

Image
  Most AI answers arrive as essays. OpenAI's new Decisions API doesn't write a word — it answers yes or no, picks from your categories, or scores on your rubric, in 100 to 180 milliseconds. It went generally available this week, and the backstory is the best part: OpenAI's own product lead, Nikunj Handa, reportedly admitted the product wasn't on the roadmap four weeks ago. A small startup forced the sprint. Yes or no, in 100 milliseconds The API runs on GPT-6 Luna. Developers send text or images plus typed questions and get machine-readable answers in three shapes: a probability that a condition is true, a pick from a fixed list with a probability for each, or a score on rubric levels you define. Input costs $0.10 per million tokens, and output tokens are free. It launched as a public beta on October 6 (after a limited DevDay preview in late September), and the general release adds voice and visual input plus geographically targeted inference.

7 Best AI Coding Tools in 2026

7 Best AI Coding Tools in 2026 cover — robot writing glowing code

You no longer need to be a "10x engineer" to ship like one. AI coding tools have quietly become the biggest productivity upgrade in software in decades — they write the boilerplate, catch bugs before you hit run, and some even build whole apps from a single prompt. Here's an honest rundown of what's actually worth your money right now, including two big names that are quietly fading.

1. Cursor — the AI-native editor

Cursor is what you get when an editor is built around AI instead of bolting it on: an Agent Mode that edits across multiple files, indexes your whole codebase, and plans multi-step changes. It has a free Hobby tier, and Pro is $20 a month — but billing is usage-based, so heavy agent users can burn through their monthly allowance fast. If you want the full agentic coding experience inside your editor, this is the benchmark. For a deeper head-to-head, see our Cursor vs GitHub Copilot comparison

2. GitHub Copilot — the safe default

Copilot works in almost every IDE you already use, plugs deep into GitHub with pull-request reviews and coding agents, and now lets you pick between Claude, GPT, and Gemini models. There's a free tier, Pro is $10 a month, and Pro+ is $39 — but note that June 2026 switched chat and agent use to a token-based credit pool, so heavy users should budget carefully. Best pick if you're a beginner or already live inside VS Code or JetBrains.

3. Windsurf (now Devin Desktop) — no billing surprises

Windsurf's Cascade agent plans and executes multi-file changes with terminal access, and its Pro plan at $20 a month uses predictable quotas instead of usage-based billing — a relief after stories of surprise AI bills. The free tier is generous too. One thing to know: Cognition AI acquired it in June 2026 and renamed it Devin Desktop, so its roadmap is in new hands.

4. Codeium — the free-autocomplete pick, with a caveat



Codeium made its name on genuinely free, unlimited autocomplete in 70+ languages inside any IDE. The honest update: the company became Windsurf, so the old Codeium extension is now the Windsurf Plugin — still installable and maintained, but it's not getting new models or features. Great free pick for students on zero budget; everyone else should look at Windsurf itself.




5. Tabnine — the privacy pick for enterprises






Tabnine is the coding AI for teams that can't let code leave the building: it runs on your own servers or air-gapped, with zero code retention and SOC 2 and GDPR compliance. There is no free tier anymore (the free plan ended in April 2025), and the enterprise platform starts around $39 per user a month. The choice for banks, hospitals, and defense contractors — overkill for hobbyists.







6. Claude Code — the terminal-native agent




Anthropic's command-line agent is superb at understanding big codebases and doing careful refactors — it feels less like autocomplete and more like a senior engineer looking over your shoulder. It runs through your Claude subscription (Pro from $20 a month), which is a bargain if you already pay for Claude. Best for developers who live in the terminal. It's part of the same wave as proactive AI agents like Claude Duet.

7. Replit Agent — idea to deployed app in one tab

Replit is the only tool here that needs zero setup: describe an app and Agent 3 builds, tests, hosts, and deploys it right in your browser. Core is $25 a month with $25 of usage credits — but billing is effort-based and failed attempts still consume credits, with spending caps off by default, so set your limits. The output is prototype-grade and needs review, but for beginners who want to ship without installing anything, nothing beats it. More on what's behind Replit Agent 


The honest verdict

Beginners: start with GitHub Copilot's free tier or Replit. Daily-driver developers: Cursor or Claude Code, depending on whether you prefer an IDE or the terminal. Teams with compliance requirements: Tabnine. And note what I left out — Amazon Q Developer is closed to new signups and support ends in April 2027, so I won't recommend a dying tool. Prices move fast in this market, so treat them as a snapshot and check the official pages before paying.
