Anthropic has released Claude Opus 4.7, positioning it as a more accessible and safer alternative to its unreleased Claude Mythos model — a highly advanced AI that the company says poses cybersecurity risks and has been kept from public release.

What's Different in Opus 4.7

1. More Literal Prompt Understanding

Anthropic says Opus 4.7 takes prompts more literally rather than loosely interpreting wording. This is particularly useful for vibe coders and users who need straightforward, predictable AI outputs without the model "reading between the lines."

2. Aesthetic Improvements

Opus 4.7 upgrades the visual quality of its outputs:
- Slide decks: More professional and tasteful formatting
- Documents: Better structure, cleaner presentation
- Anthropic uses the word "tasteful" to describe the output quality

3. Safety First

Unlike the powerful but dangerous Mythos model (which Anthropic says could pose cybersecurity risks), Opus 4.7 is designed to be broadly usable without the safety concerns of frontier models.

Pricing

| Metric | Opus 4.7 | Opus 4 |
|--------|----------|--------|
| Input (per 1M) | $5.00 | $15.00 |
| Output (per 1M) | $25.00 | $75.00 |

Opus 4.7 is significantly cheaper than Opus 4, making it more accessible for a broader range of use cases.

How It Fits in Anthropic's Lineup

| Model | Position | Best For |
|-------|----------|----------|
| Mythos | Frontier (unreleased) | Research only — cybersecurity risks |
| Opus 4.7 | Advanced | Complex reasoning, aesthetic outputs |
| Sonnet 4 | Balanced | Everyday tasks |
| Haiku | Fast | Simple, high-volume tasks |

Why This Matters

1. Vibe coding is growing: Developers using AI to code need models that follow instructions precisely, not interpret them creatively
2. Aesthetics matter: Better-formatted outputs save editing time for documents and presentations
3. Safety over power: Anthropic's decision to withhold Mythos shows a responsible approach to AI development
4. Competitive pricing: At $5/$25 per million tokens, Opus 4.7 is priced competitively against GPT-5.5 ($5/$30)

Comparison with Competitors

| Model | Input | Output | Key Focus |
|-------|-------|--------|-----------|
| Claude Opus 4.7 | $5.00 | $25.00 | Safety, aesthetics, literal prompts |
| GPT-5.5 | $5.00 | $30.00 | Coding, computer use, research |
| DeepSeek V4 | $1.74 | $3.48 | Open source, agentic tasks |
| Gemini 3.1 Pro | $2.00 | $12.00 | Multimodal, Google ecosystem |
