Every AI newsletter is running "GPT-6 is coming!" headlines. Most mix confirmed facts with unverified rumors without labeling which is which. I tracked every public signal and separated them.
What's Actually Confirmed
| Fact | Source |
|---|---|
| Pretraining finished March 24, 2026 | The Information, multiple credible trackers |
| Trained at Stargate Abilene, 100,000+ H100 GPUs | OpenAI official |
| Sam Altman: "a few weeks" away | Public statement, March 24 |
| Greg Brockman: "not an incremental improvement" | Public statement |
| OpenAI killed Sora to redirect GPU capacity | Multiple reports |
What's NOT Confirmed (But Everyone's Reporting As Fact)
| Claim | Reality |
|---|---|
| 40% better than GPT-5.4 | Single unverified insider leak |
| 2M-token context window | Same unverified source |
| April 14 launch date | Anonymous blog post, no track record |
| SWE-bench Pro in high 70s | Community speculation, no model card |
| Named "GPT-6" vs "GPT-5.5" | Marketing decision not yet public |
Release Timeline: What Prediction Markets Say
- Polymarket: 78% by April 30
- Manifold: 82% by May 15
- Polymarket: >95% by June 30
Late April to mid-May is the most probable window. Even if the model is ready, OpenAI stages rollouts: Plus/Pro subscribers first, free tier 2-4 weeks later, API after consumer launch.
The Part Developers Actually Care About: Pricing
No pricing announced. But we can estimate from patterns.
Current GPT-5.4 pricing:
| Model | Input/M tokens | Output/M tokens |
|---|---|---|
| GPT-5.4 Standard | $2.50 | $15.00 |
| GPT-5.4 Pro | $30.00 | $180.00 |
| GPT-5.2 | $1.75 | $14.00 |
GPT-6 pricing estimate (two scenarios):
| Scenario | Input/M | Output/M |
|---|---|---|
| Premium launch | $5.00-8.00 | $20.00-30.00 |
| Competitive (Claude/DeepSeek pressure) | $3.00-5.00 | $15.00-20.00 |
If the 2M context window is real, expect 2x+ multiplier for extended context requests — same pattern as GPT-5.4's pricing above 272K tokens.
3 Cost Dynamics That Will Shift
1. Agentic tasks = unpredictable token spend. A request like "research competitors and write a report" could burn 50K-500K tokens internally. Budget for variance.
2. Memory reduces redundant context. If persistent memory works, you stop re-sending conversation history every call. Could cut input costs 30-50% for long conversations.
3. Not every task needs GPT-6. Route simple classification to GPT-5.2 ($1.75/M) or DeepSeek V4 ($0.30/M). Reserve GPT-6 for complex reasoning. Smart routing saves 40-60% on total API spend.
Projected cost comparison:
| Monthly volume | GPT-6 only | Smart routing | Savings |
|---|---|---|---|
| 10M tokens | $50-80 | $15-30 | ~60% |
| 100M tokens | $500-800 | $120-250 | ~70% |
What To Do Right Now
- Stop hardcoding model names. Use a config variable. When GPT-6 drops, change one parameter.
- Audit your top 20 prompts. Count tokens. Compress anything over 100K.
- Set up model routing. Classify calls by complexity. Simple tasks don't need frontier models.
- Budget 2-3x on complex tasks. Higher per-token cost, but fewer retries if the performance leap is real.
