Anthropic has released a new model: Claude Opus 4.7 😈

Anthropic just launched Claude Opus 4.7 — their most powerful publicly available model to date. And in the comparison table, they also showed Claude Mythos Preview — an internal “monster” that’s not yet available to everyone (due to its powerful cyber capabilities).

Agent-based programming (most important for developers)
SWE-bench Pro (complex real-world bug fixing tasks):
Mythos Preview — 77.8% | Opus 4.7 — 64.3% | Opus 4.6 — 53.4% | GPT-5.4 — 57.7%
SWE-bench Verified: Mythos — 93.9% | Opus 4.7 — 87.6% | Opus 4.6 — 80.8%

This is a huge leap. Mythos nearly doubles the results of models from 2024–2025 on real GitHub tasks.
Terminal-Bench 2.0 (terminal work, agent coding):
Mythos — 82.0% | GPT-5.4 — 75.1% | Opus 4.7 — 69.4%

Multidisciplinary thinking and complex tasks Humanity’s Last Exam (one of the toughest “final exams of humanity,” multidisciplinary, graduate-level):

Mythos — 56.8% | Opus 4.7 — 46.9% With tools: Mythos — 64.7% | Opus 4.7 — 54.7%
GPQA Diamond (high level of scientific thinking): All top models around 94%, Mythos slightly ahead — 94.6%.

Agent capabilities
Scaled tool use (MCP-Atlas):
Opus 4.7 — 77.3% (leader among available)
Agentic computer use (OSWorld-Verified): Opus 4.7 — 78.0% | Mythos — 79.6%
Agentic search (BrowseComp): GPT-5.4 leads with 89.3%, Mythos — 86.9%
Cybersecurity vulnerability reproduction (CyberGym): Mythos — 83.1% (especially powerful here)

Visual thinking and multimodality CharXiv Reasoning: Opus 4.7 without tools — 82.1% | with tools — 91.0% Mythos — 93.2% with tools.
Multilingual Q&A (MMMLU): Opus 4.7 and 4.6 — about 91%, Gemini 3.1 Pro — 92.6%.

Opus 4.7 is the best choice right now for most tasks:
Significantly better than Opus 4.6 in almost everything (especially in agent coding, computer use, visual reasoning, and financial analysis).
Price remains the same: $5 / $25 per million tokens.
Available to everyone via Claude, API, Bedrock, Vertex AI, etc.
Improved handling of high-quality images (up to 3.75 MP), new “extra high” effort level, ultra review in Claude Code, and more.

Mythos Preview is truly next-level — a beast. It dominates nearly all agent-based and complex benchmarks. Anthropic keeps it in limited access (Project Glasswing) because the model is especially strong at finding and reproducing vulnerabilities in code. Essentially — it’s “cyber-weapon” level frontier tech, currently being tested with enhanced safeguards. Anthropic openly states: Opus 4.7 lags behind Mythos in almost all axes, but it’s safer and already available for production.

2026 won’t be just about “chatbots.” We’re seeing real agents that can work for hours in the terminal, fix actual code, analyze finances, and solve PhD-level problems.
Opus 4.7 is already ready for deployment in complex workflows. Mythos hints at where the industry is heading in the coming months.

Maybe this is already the future?
