The government is leading us down a very dangerous road.

This will dramatically worsen inequality.

This is so sad

OpenAI@OpenAI

We believe in broad access and plan to make GPT-5.6 Sol, Terra, and Luna generally available in the coming weeks.

For now, at the request of the U.S. government, we’re starting with a limited preview among a small group of trusted partners in Codex and the API.

The limited rollout of GPT-5.6 to a small group of customers has begun. It comes in three variants: GPT-5.6-Luna GPT-5.6-Terra GPT-5.6-Sol

have been testing 5.6 for a while and VERY happy with it. DO NOT view this as just a “cyber” release, it is the new sota workhorse model, completely replacing opus for 80% of tasks for me

> GPT‑5.6 Sol is competitive with Mythos Preview using only ~1/3 of the output tokens.

this is a very key line. OAI posttraining team has shifted the reasoning pareto frontier by A LOT and they arent saying anything about how they did it because this is the single most important competitive advantage right now in agentic models for enterprise.

team really locked in on this one, i honestly wish they just went ahead and called it GPT6 because this minor semver bump is far larger than even the 5.4->5.5 jump which itself was the single most successful openai launch since 4o/o1

Sol is our new flagship and a step function better than GPT-5.5.

Terra delivers performance competitive to GPT-5.5 at 2x lower cost.

Luna is our most cost-efficient model, delivering strong capability at our lowest cost.

Together, the GPT-5.6 family gives people and developers more choice in how they balance intelligence, speed, and cost.

GPT-5.6 Pricing: - Sol: $5 / $30 - Terra: $2.5 / $15 - Luna: $1 / $6

OpenAI will also launch GPT-5.6 on Cerebras at up to 750 tokens/s in July

GPT‑5.6 Sol sets a new state of the art on Terminal‑Bench 2.1, which tests complex command-line workflows requiring planning, iteration, and tool coordination.

Welcome to the new, confusing era of AI.

If the government allows, you get access.

If not, welp. You’re shit out of luck.

GPT-5.6 Sol is our most capable model yet for cybersecurity.

It shifts the performance-efficiency frontier for long-horizon security tasks including vulnerability research and exploitation.

GPT‑5.6 Sol launches with our most robust safety stack yet.

We strengthened real-time protections against high-risk cyber activity and repeated misuse, then spent weeks hardening the system with human red teaming and over 700,000 A100-equivalent GPU hours of automated testing.

Chubby♨️@kimmonismus

OpenAI priced GPT-5.6 Sol (largest Model) closer to Claude Opus 4.8 than to Anthropic’s restricted Mythos 5. Price war started.

Sol comes in at $5 input / $30 output per 1M tokens. For comparison:

Claude Opus 4.8: $5 / $25 Claude Mythos 5: $10 / $50 GPT-5.6 Terra: $2.50 / $15 GPT-5.6 Luna: $1 / $6

That makes Sol more expensive than Opus 4.8 on output, but far below Mythos 5 on both input and output.

And: "Terra has competitive performance to GPT‑5.5 while being 2x cheaper and Luna brings strong capability at our lowest cost."

They are also releasing Sol on Cerebras-Chips:

"We're also launching GPT‑5.6 Sol on Cerebras at up to 750 tokens per second in July, bringing frontier intelligence to customers at unprecedented speed."

A truly exciting release. OpenAI is entering the price war with this one.

And I love the names: Sol, Terra, Luna. Sounds fantastic!

Hyped for the release!
