Breaking Down OpenAI's Upcoming Model Lineup
Leaked images of OpenAI's next model announcement show five new models, and here is what they tell us.
Five Models, One Leak
A leaked image hints at five launches:
- GPT-4.1: The new flagship, building on GPT-4o with sharper reasoning.
- GPT-4.1 mini: Mid-sized, balancing cost and performance for most business use cases.
- GPT-4.1 nano: The smallest, targeting edge devices or budget-conscious deployments.
- o3: A separate line from GPT, possibly focused on planning or specialized reasoning.
- o4-mini: A mini version of a model (o4) that hasn't been fully revealed yet — suggesting either technical hurdles or a staggered rollout.
Pricing and Latency
The leak also reveals tiered pricing:
| Model | Input (per 1M tokens) | Cached Input | Output (per 1M tokens) | Latency vs GPT-4o |
|---|---|---|---|---|
| GPT-4.1 | $2.00 | $0.50 | $8.00 | Similar |
| GPT-4.1 mini | $0.40 | $0.10 | $1.60 | 40% faster |
| GPT-4.1 nano | $0.10 | $0.025 | $0.40 | 50% faster |
GPT-4.1 nano at $0.10 per million input tokens is 20x cheaper than the flagship. For large-scale AI workloads, that gap changes what's worth building.
Anthropic and Mistral Got Here First
OpenAI is responding to competition. Anthropic and Mistral beat them to tiered pricing. The flagship 4.1 will probably be impressive, but the mini and nano models matter more — they make advanced AI affordable for smaller projects and experimental work.
The o4-mini's early appearance is odd. My guess: OpenAI wants to test a smaller version before rolling out the full o4, or they're still fixing the main model.
What to Expect
- GPT-4.1: Better multimodal support, stronger reasoning, fewer hallucinations.
- Mini/nano: Speed and affordability, not bleeding-edge capability.
- o3: OpenAI's answer to planning, logic, and agentic workflows.
- o4-mini: A preview of the next-gen architecture with training wheels on.
I'll follow up once the specs are public.
