Claude Sonnet 5.5

Review a change or plan delivery when the decision spans several sources.

Claude Sonnet 5.5 is a Claude model for work such as coding and document reasoning. Use it on TokenHot to review changes, compare visible product behavior with requirements or plan around dependencies.

  • Text and image input
  • Text output
  • 1M-token catalog context

TokenHot's public API example uses text in Messages. The chat Playground accepts one new image attachment per message. Anthropic's adaptive thinking settings describe its own API, so confirm parameter support for your integration.

Overview

What is Claude Sonnet 5.5?

Package the evidence around the decision. Label the contract, the current state and the proposal so the model can connect each finding to the right source.

Use the catalog's context window as a capacity reference. Supply relevant excerpts and request an output that reviewers can inspect. A long input does not replace source checks.

Engineering teams

Review a change across system boundaries

Supply the proposed change, current interface contract and affected consumers. Ask for an impact review that identifies the dependency behind each finding.

Product and QA teams

Compare a screenshot with acceptance criteria

Attach one screenshot and supply the acceptance checklist as text. Ask for visible pass, fail or unknown items with a reason for each.

Delivery and platform teams

Plan delivery gates around a blocker

Provide the milestones, constraints and dependency owners. Request a phased plan that keeps a blocked path separate from work that can continue.

Tools you need
Labeled source material, a review checklist and a reviewer.
Keep in mind
Check findings in the real repository and run validation separately.
View a task brief

Compare the proposal with the current contract. For each affected consumer, cite the relevant clause and suggest a test. Separate confirmed incompatibilities from assumptions.

Tools you need
Labeled source material, a review checklist and a reviewer.
Keep in mind
Behavior outside the screenshot needs independent verification.
View a task brief

Review the screenshot against the supplied checklist. Give each item a pass, fail or unknown status with visible evidence. Explain how to verify the unknown items.

Keep in mind
A plan requires owner review before changes are scheduled.
View a task brief

Turn the notes into a staged plan. Show dependencies, name the check for each gate and split out work that can continue while the blocker remains open.

Anthropic

Related models

ClaudeAnthropicClaude Fable 5 1

A flagship long-context model for demanding, long-running knowledge work, coding projects, and multi-step agentic tasks. It accepts text, images, and PDFs, making it a strong fit for cross-file analysis, complex research, and sustained tool use. It prioritizes reasoning depth and long-horizon execution over speed and cost, so it is best reserved for tasks where reliable completion matters.

$3.4/1M tokensClaudeAnthropicClaude Opus 4 5

An earlier Opus model in the Claude 4 family, focused on difficult coding, agents, computer use, deep research, and work with slides and spreadsheets. It fits workflows that require Opus-level capability with 4.5 compatibility; without that constraint, evaluate the newer Opus 4.6 or 4.7 first.

$3.5/1M tokensClaudeAnthropicClaude Fable 5

Anthropic's most capable widely released model, built for the most demanding reasoning and long-horizon agentic work. Offers a 1M-token context window with 128k max output and always-on adaptive thinking, excelling at autonomously exploring underspecified tasks, planning, and carrying long-running coding and multi-agent orchestration further before it needs human input.

$3.4/1M tokensClaudeAnthropicClaude Fable 5 2

Anthropic's top tier for the most demanding technical work: a 1M-token context window, always-on adaptive extended thinking (high by default, up to max), and up to 30% faster output than Fable 5.1. Best suited to open-ended problems without a known solution, such as large-scale code migrations, cross-file engineering changes, and hard research or math, where long-running autonomous work pays off. For everyday coding and knowledge tasks Anthropic still recommends starting with Opus 5.5. At $8/M input and $40/M output tokens, cost is the main reason to reserve it for genuinely hard problems instead of using it as the default.
