OpenAI's latest leap in reasoning has arrived. Featuring the new "Thinking" and "Instant" variants, targeting complex agentic workflows and human-level reliability.
The following videos reflect community reactions, independent experiments, and interpretations of recent model behaviors. Note: These represent opinions and are not official OpenAI confirmations.
An in-depth look at potential capabilities discussed in developer circles. This video explores the theoretical performance jumps from GPT-4 to a hypothetical 5.2 iteration.
Experts debate the system architecture required for the next leap in reasoning. This analysis focuses on the compute vs. efficiency trade-offs expected in future models.
We prioritize confirmed data. Below are summaries of relevant official communications that define the current landscape.
According to documentation referenced in this context, OpenAI focuses on incremental systemic improvements. Official posts often detail safety evaluations and architectural refinements rather than marketing hype.
As stated in official system card updates, safety protocols and red-teaming results are prerequisites for any public release. This document typically outlines the rigorous testing phases new models undergo.
Confirmed specifications, GDPval benchmarks, and how the new "Thinking" model stacks up against Gemini 3 and Claude Opus 4.5.
SOTA
Sets new record on GDPval knowledge work tasks, performing at human expert level.
1.6%
Hallucination rate dropping to 1.6%, a massive improvement over previous generations.
400k
Unified input/output context limit of 400,000 tokens for deep document analysis.
Instant / Thinking / Pro
Instant for speed, Thinking for complexity, Pro for max intelligence.
| Feature | GPT-5.2 (Thinking) | Gemini 3 Ultra | Claude Opus 4.5 |
|---|---|---|---|
| Status | Released Dec 11 | Released | Released |
| Core Strength | System 2 Reasoning | Multimodal Native | Creative Writing |
| Context Window | 400k Tokens | 2M+ Tokens | 500k Tokens |
| GDPval Score | Highest (Expert) | Very High | High |
OpenAI releases the base GPT-5 model, setting the stage with improved agentic capabilities.
The "Thinking" and "Instant" models are released to Plus/Pro users and API, responding to "Code Red" internal alerts.
Analysts predict the "Instant" model will become available to free users as compute costs stabilize.
Unlike automated aggregators, ChatGPT52.org works with a community of 50+ developer beta testers. Our data is verified against:

Yes! As of December 11, 2025, GPT-5.2 is live for paid subscribers and API developers. It includes the new Thinking and Instant variants.
Multiple sources report a potential "Pro" tier priced at roughly $200/mo for heavy compute tasks (like full "Thinking" models). This is likely separate from the standard $20 Plus plan.
Gemini 3 Ultra is a formidable competitor with a larger context window (2M+). However, GPT-5.2 'Thinking' currently holds the crown for pure reasoning tasks (GDPval) and reliability.
OpenAI typically offers a "mini" or "turbo" model for free users eventually. However, the top-tier "Pro" reasoning models will likely remain paid. Avoid links promising "free access" to the full model today.
