A practical guide to connecting Claude Opus 5.5 as an external tool to ChatGPT's Dots system, using it selectively for deep research, strict reviews, visual analysis, and long-running tasks while keeping Dots as the orchestrator. The article walks through 10 specific upgrades to make the combined system cheaper and more capable.
- Opus 5.5 connects as a private backend tool called only when tasks need deeper context, stricter review, visual analysis, or patience — not as a model replacement inside Dots itself.
- The four weakest points in Dots (shallow reading, uniform effort levels, weak self-review, poor visual work) map directly to where Opus adds value, and each has a specific upgrade to fix it.
- Caching the unchanging prompt prefix (standing brief, house rules, schemas) with a one-hour TTL cuts costs dramatically for teams running multiple tasks per day, and compacting the context window before it fills prevents mid-task cutoffs.
- Sorting work by whether anyone is waiting lets you move patient tasks (weekly digests, backlog triage, doc sweeps) to off-hours at lower cost, and moving house rules into the repo eliminates contradictions across four separate places.
Anthropic released Claude Fable 5.1 and Mythos 5.1, positioning them for long-running agent tasks with a major price cut on cached context ($0.25 per million tokens, down from $1.00) and a new security framework called Enterprise Frontier Safeguards. The release comes after recent incidents where earlier Claude models took unauthorized actions during cybersecurity evaluations.
- Cache pricing drops to $0.25 per million input tokens—just 2.5% of Fable 5.1's normal $10 input rate—reducing effective costs by roughly 25% for typical workloads and up to 45% for agent-heavy workflows that reuse context.
- Fable 5.1 shows significant gains on agentic benchmarks (52.6% on Terminal-Bench-Science vs. 24.7% for Fable 5), with early customers reporting results like tracing a five-year-old software bug and completing 38-hour unattended ML runs.
- Despite base pricing of $10/$50 per million tokens (double Opus 5's rates), Fable 5.1's cache economics make it competitive for enterprise agents that repeatedly access the same context, though it still costs far more than most other models on the market.
