### Key concepts
- I Mapped the Opus 4
- 7 Release to Your Role, Goals, and Real Workflows

### Extractable claims (15)
1. Anthropic shipped Claude Opus 4.7 on April 16, 2026.
2. Opus 4.7 is a careful tune-up of Opus 4.6, better at long, agentic work, dramatically better at seeing screenshots, and stricter about literal instruction‑following.
3. The tokenizer changed, so the same input now counts as about 1.0–1.35x more tokens depending on whether you’re passing text or code.
4. By default, Claude Opus 4.7 omits the reasoning summary from the response stream.
5. Opus 4.7 is stricter about following only what you explicitly ask for, so it no longer “fills in” a vague brief with its own assumptions.
6. This is the first release where overnight agent work shifts from experiment to something we can trust with a credit card.
7. The new /ultrareview command acts like a skeptical senior engineer reviewing our code.
8. Vision is the sleeper upgrade in this release: maximum image resolution jumped from 1.15MP to 3.75MP.
9. The tokenizer change is a price increase Anthropic didn’t label as a price increase.
10. A typical vibe‑coder workflow will see higher spend for the same work unless we retune our prompt math.
11. Routines launched on April 14 in research preview, with three flavors: Scheduled Routines, API Routines, and Webhook Routines.
12. File-based memory is stronger, which makes the “Claude.md plus a notes/ directory” pattern more reliable.
13. Auto mode on Max now lets Claude keep going without pinging us for every little decision.
14. The headline price for Claude Opus 4.7 did not change: still $5 per million input tokens and $25 per million output tokens.
15. Opus 4.7 is meaningfully better at writing and using file-system-based memory across long, multi-session workflows.

8. By the second run, the prompt is more precise than what we originally wrote.
9. Native rewriting optimizes for connector accuracy.

11. The self-improving loop rewrites the execution strategy itself: what to look for, how to structure outputs, which edge cases to ignore.
12. The Claude Code path wins on depth of the optimization system, while the Claude Cowork path wins on accessibility.
13. Without the improvement directive, Claude Cowork rewrites for connectors.
14. With the improvement directive, Claude Cowork rewrites for outcomes.

### Key concepts
- Tested workflow patterns for agentic AI builders in 2026
- Save Credits in Perplexity Computer
- Advanced Guide, Part 2 (2026)

### Extractable claims (15)
1. Every message in a thread makes the next message more expensive.
2. The compound context tax in Perplexity Computer means each message in a thread costs more than the previous one because the model re-processes the entire history.
3. When we send message number 50 in a thread, the model re-reads the entire conversation history before processing the new prompt.
4. Running an SEO audit at message 5 in a clean thread might cost 40 credits, while the same audit at message 50 can cost five to eight times that price.
5. The compound context tax applies to any agentic AI system that bills by token volume or context length.
6. Long threads are expensive threads.
7. The fresh thread rule for Perplexity Computer is the single lowest-effort, highest-impact credit-saving habit.
8. Any task that takes an input and produces an output should run in a clean thread.
9. If a task is self-contained, it does not belong inside an existing conversation.
10. The key habit for credit efficiency is saving your work to a file before switching contexts.
11. The two-thread pattern for agentic AI splits strategy work from execution work into separate threads.
12. The strategy phase is where AI earns its credits by analyzing content, proposing options, and making judgments.
13. The execution phase is mechanical and renders the thing the strategy phase designed.
14. Combining both strategy and execution in one thread is wasteful because the execution phase carries the full context of the strategy session.
15. Saving reports to files is the simplest optimization nobody does.

### Key quotes
> Every message in a thread makes the next message more expensive.
> Long threads are expensive threads.
> The fresh thread rule for Perplexity Computer is the single lowest-effort, highest-impact credit-saving habit.
