Anthropic Leaks Next AI Model ‘Mythos’ — What We Know So Far (March 2026)

Anthropic’s Next AI Model Name Revealed: Mythos

In a significant security lapse, Anthropic — the company behind Claude AI — has accidentally revealed details of its next unreleased model. According to a Fortune exclusive report, the upcoming model is codenamed “Mythos” and was discovered in an unsecured data store alongside other internal company information.

The leak also exposed details of an invite-only CEO event and other internal business information, raising serious questions about Anthropic’s data security practices.

What We Know About Mythos

While the full specifications remain unclear, here’s what’s been pieced together from the leak and industry context:

• Name: Mythos (likely the next generation after Claude 3.5 Sonnet/Opus)
• Discovery: Found in an unsecured data trove accessible without authentication
• Timing: Leaked in late March 2026, suggesting a mid-2026 release window
• Context: Comes as Anthropic faces legal battles over First Amendment issues with a federal judge

The AI Race Heats Up

This leak comes at a critical time in the AI industry:

Google’s TurboQuant Breakthrough

Google Research just unveiled TurboQuant, a compression algorithm that can reduce AI memory usage by at least 6x with zero accuracy loss. This could make running powerful AI models significantly cheaper and faster.

Apple’s Secret Gemini Deal

Apple has reportedly secured complete access to Google’s Gemini model in its data centers. The deal allows Apple to use Gemini to train smaller, more efficient “student” AI models through a process called distillation — specifically tuned for Apple devices.

This means Siri could get dramatically smarter in the next iOS update, powered by Google’s technology under the hood.

Intel Enters the AI Hardware Race

Intel announced the Arc Pro B70, a dedicated AI GPU starting at nearly $1,000. While not competing with NVIDIA’s top-tier cards, it signals Intel’s serious push into AI computing hardware.

AI Music Generation Advances

On the creative front, new AI music models can now be trained on your own voice and songs, enabling personalized music generation. The music industry is quietly embracing AI more than anyone admits — producer Young Guru estimates that more than half of sample-based hip-hop is now made using AI-generated samples.

Privacy Concerns: Google AI Search Under Fire

In a disturbing development, Google’s AI-powered search tool is being accused in a class action lawsuit of disclosing personal information of Jeffrey Epstein survivors. The case alleges that Google “has failed and refuses to remove, de-index, or block access to the offending materials.”

This highlights the ongoing tension between AI capabilities and privacy protection.

What This Means for You

The AI landscape is evolving at breakneck speed:

• For developers: Keep an eye on Mythos — Anthropic’s models have been the go-to for coding and complex reasoning tasks
• For consumers: Apple’s Gemini integration means better AI on your iPhone, coming soon
• For investors: Google’s TurboQuant could dramatically reduce AI infrastructure costs, benefiting the entire industry
• For privacy advocates: The Google AI search lawsuit could set important precedents for AI and personal data
