A lower-priced Opus route with a 1M context window and always-on adaptive thinking. It is a credible long-agent candidate, but orchestration behaviour and provider claims require a same-work migration test, so HubAI withholds a score.

Supplier information and independent test results are separate. Check the linked product and pricing sources before purchase.
What an independent test needs to cover
Test output accuracy, retries, reviewer effort, data handling and total cost using the pilot below. No completion date is scheduled; a score will require a published method and results.

Approval does not establish UK entitlement, free usage, client-facing productization permission or independent safety. Identity readiness and retention determine deployment fit.

WHAT IT IS
Claude Opus 5.5, explained.
Claude Opus 5.5 is designed for long-running agentic coding and professional knowledge work where migration changes can be tested before production. HubAI treats it as a workflow purchase rather than a novelty: the relevant question is whether it produces an acceptable result repeatedly, with controls your team can understand and a cost that remains predictable after the trial ends.

PROOF TESTRequired before scale
Pin Opus 5.5 in a test environment and replay representative long-running workflows. Record accepted tasks, thinking and tool orchestration changes, unsupported output, computer-use compatibility, cache use, latency, reviewer minutes and complete billed cost.
STRENGTHS
What earns its shortlist place.
+01
Published one-million-token context window and 128K output limit
Why it matters: accelerates repository navigation.
+02
Available through Anthropic, AWS, Google Cloud and Microsoft Foundry routes
Why it matters: removes repetitive implementation work.
+03
Lower published standard token rates than the preceding Opus release
Why it matters: keeps explanation and change close together.
LIMITATIONS
What can break the business case.
−01
Adaptive thinking cannot be disabled and forced tool use can return an error
Buyer impact: can create plausible but fragile code.
−02
Older computer-use and cross-model thinking-block assumptions may require migration work
Buyer impact: moves effort into review and testing.
−03
Benchmark, speed, workload-cost and safety comparisons are provider-reported
Buyer impact: requires policy controls for private repositories.
Cost reality
The subscription price is only the starting point. HubAI evaluates usage limits, failed attempts and the work needed to produce one usable result. Pricing changes frequently, so the structure and verification date matter more than a headline price.
PRICING DECODER
Budget for the result, not the plan badge.
Published structure
$4/1M input and $20/1M output at standard API rates; cache reads cost $0.20/1M, five-minute writes $5/1M and one-hour writes $8/1M; Fast mode is $8/$40 · Profile record only; separate pricing check not recorded: 23 September 2026. USD list price; UK price/VAT to confirm.
Free or trial route
Paid API and cloud-platform access; availability across Claude plans varies by entitlement and route
Primary cost driver
seat price, premium requests, agent runs and reviewer correction time
Budget test
Record the total cost, attempts and human correction needed to produce ten accepted results.
Separate pricing check date: not recorded. Profile review: 23 September 2026. Confirm live price, VAT, region, usage rights and cancellation terms with the vendor before purchase.
HUBAI TRUE COST LAB
What does one accepted result really cost?
Model your own usage. HubAI separates subscription cost from retries and human review—without pretending a headline plan price tells the whole story.

Prepare approved source material, examples and a clear acceptance standard.
Run three realistic tasks and record attempts, correction time and export quality.
Keep human approval before publishing, sending or acting on the result.
READY-TO-USE PROMPTS
Start with a better brief.
01Act as a specialist in model ai. Ask me three questions before creating the first draft. The outcome I need is: [describe outcome].
02Create two approaches for [task]. Use this audience: [audience]. Respect these constraints: [constraints]. Explain the trade-off between the two approaches.
03Review this output against accuracy, tone, privacy, cost and usability. List the changes required before a person should approve it.
RISK & GOVERNANCE
What to check before adoption.
Do not place confidential, personal or rights-restricted material into Claude Opus 5.5 until your organisation has reviewed its current terms, retention settings and account controls. AI output can be plausible and still wrong; regulated, financial, legal and employment decisions require qualified human review.
