Core News
GPT-6’s codename is confirmed as “Goblin”, planned for official announcement at OpenAI DevDay on September 29, 2026. The news first leaked via Polymarket and spread widely on X, earning 2,800+ likes and 291 bookmarks.
Sam Altman will personally announce “Artificial Goblin Intelligence”—both a playful response to the AGI concept and an OpenAI branding strategy.
GPT Series Timeline
| Version | Release | Key Features |
|---|---|---|
| GPT-4 Turbo | 2023.11 | 128K context, lower cost |
| GPT-4o | 2024.5 | Multimodal real-time |
| GPT-5 | 2025 | Reasoning significantly improved |
| GPT-5.5 | 2026.Q1 | Intelligence Index 60, current highest |
| GPT-6 “Goblin” | 2026.9.29 | TBD, expected AGI-level |
Aschenbrenner’s AGI 2027 Prediction Back in Focus
Leopold Aschenbrenner’s story intersects interestingly with GPT-6’s timeline:
- Left OpenAI in April 2024
- Published 165-page paper “Situational Awareness” predicting AGI by 2027
- Founded Situational Awareness Fund
- Turned $225M into $5.5B in 12 months
If GPT-6 demonstrates near-AGI capabilities, Aschenbrenner’s prediction faces its ultimate test.
Impact on Competitive Landscape
GPT-6’s September timing overlaps with domestic models’ release window:
| Model | Expected | Competition with GPT-6 |
|---|---|---|
| Kimi K3 | 2026.Q3 | Direct collision, 2.5T parameters |
| Qwen new version | TBD | Alibaba may launch early to hedge |
| DeepSeek V4 Pro | In testing | Cost-performance competition |
| Claude Opus 5 | TBD | Anthropic may accelerate |
OpenAI’s Core Challenges
- Codex alone is thin: Anthropic has Claude Code + Cowork + MCP + Skills; OpenAI only has Codex
- Open-source catching up: GPT-5.5’s Intelligence Index advantage is narrowing
- Multi-front battle: Sora (consumer), Pulse (consumer), Codex (developer) scattering resources
Recommendations
| Role | Action |
|---|---|
| Enterprise CTO | Complete current model evaluation before September; GPT-6 may reshuffle |
| Developers | Track GPT-6 API changes, prepare for adaptation |
| Investors | Watch market volatility around GPT-6 announcement |
Uncertainty Note
The “September 29” date comes from leaked information, not official OpenAI confirmation. OpenAI has a history of adjusting product timelines (GPT-5’s multiple delays).
