# Will Anthropic's Mythos reclaim the frontier?

## Question
Will [[entity-anthropic-d26|Anthropic]]'s **Mythos** model reclaim the frontier from [[entity-gpt-5-5|GPT-5.5]] when released?

## Context
The speaker mentions that [[entity-claude-opus-4-7|Claude Opus 4.7]] landed under the shadow of **Mythos** — a more advanced Anthropic model that has been **restricted due to cybersecurity concerns**. Until Mythos becomes available, Opus 4.7 is the public face of Anthropic's frontier.

## Why It Matters
If Mythos closes the execution gap with GPT-5.5 *and* retains Opus's visual taste, the routing playbook in [[action-route-complex-execution]] and [[action-route-visual-design]] would consolidate around Anthropic — assuming [[claim-anthropic-uptime-lag|infrastructure issues]] are also resolved.

## Resolution Path
Benchmarking and real-world testing of 'Mythos' upon its public or enterprise release. Re-running the [[framework-private-bench-suite|Private Bench]] (Dingo / Splash Brothers / Artemis) on Mythos would be the speaker's natural next test.
