ChatGPT Pricing Now Splits GPT-5.3, GPT-5.4 Thinking, and GPT-5.4 Pro by Plan
As of April 2, 2026, OpenAI's pricing page shows Free, Go, Plus, Pro, Business, and Enterprise tiers. GPT-5.3 appears across the ladder, GPT-5.4 Thinking starts at Plus, and GPT-5.4 Pro starts at Pro with flexible access on business plans.
Why it matters: The buying decision is now more about access tier and workflow depth than one universal flagship model. OpenAI is packaging reasoning, agent mode, and context into distinct commercial lanes.
OpenAI Has Folded Operator Into ChatGPT Agent Mode
OpenAI's Help Center says Operator functionality is now integrated into ChatGPT agent mode. The same article says agent mode is currently available on Pro, Plus, Business, Enterprise, and Edu plans, and not on Free.
Why it matters: That shifts the product story from a separate browser agent to a broader paid ChatGPT workflow surface that combines research, apps, terminal access, and web actions.
GitHub Copilot Free Now Starts With 2,000 Completions and 50 Chat Requests
GitHub's official Copilot plans pages show Copilot Free with 2,000 completions and 50 chat or agent-mode requests per month, while paid tiers expand into Pro, Pro+, Business, and Enterprise.
Why it matters: That makes Copilot easier to trial inside existing IDE habits, but the serious value still sits in the paid plans once you need more premium requests, coding agent access, or organization controls.
Gemini 3.1 Pro Preview Lists Paid API Pricing at $2 Input and $12 Output per 1M Tokens
Google's Gemini Developer API pricing page lists Gemini 3.1 Pro Preview at $2 input and $12 output per 1M tokens for prompts up to 200k tokens, with higher pricing above that threshold.
Why it matters: The important signal is not just model quality. Google is clearly segmenting premium multimodal and agentic capability with explicit API price bands instead of a single flat-rate story.
