Introducing Claude Opus 5.5, the first model in our new Claude 5.5 family.
It performs at the level of Claude Fable 5.1 for most tasks, and costs 40% less to run than Opus 5.
So we’re already seeing testing for:
Sonnet 5.2
Opus 5.2
Fable 5.2
Gemini 4 Pro
And we have confirmation or hints of upcoming releases for:
Grok 4.7
GPT-6-Sol
(Sam and Tibo teased a big release on Tuesday, so this could be it)
Kimi K3.1 (a vague post from Kimi seems to hint at 3.1)
Deepseek V5
This week was pretty boring.
But next week is probably gonna insane.
🚨 Deepseek v5 Leak: Beats Astra
> DeepSeek is reportedly preparing an imminent V5 launch
> it could match or beat Fable 5.1 and Astra
> Expected to deliver much stronger performance at a lower cost
> DeepSeek is reportedly keeping the open-weight strategy
Could DeepSeek V5 become the new king of open-weight AI?
After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI?
I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev
• 20-200x faster
• 40-400x cheaper (w/ output tokens free)
• Frontier composable intelligence optimized for decisions
AFAICT the shortest path to AI-based economic revolution

@Ananth7e@Protonnd If you don't have the money for a dgx Spark cluster and need frontier models for work ,It is definitely not dumb to have subscriptions lol
