Coding
Very strong for reading a whole codebase, planning a change and making careful edits, especially through Claude Code.
A careful, long-context assistant favoured for writing, analysis and agentic coding.
The short version
Overview
Claude is Anthropic's AI assistant. It is known for long, careful reading, clear prose and a measured tone, and it is widely used for document analysis, writing, research synthesis and software engineering.
Beyond chat, Claude offers Projects for shared context, Skills for repeatable instructions, connectors that link it to tools and data, and Claude Code for working inside a codebase. Those features make it a platform for team workflows, not just a chat box.
Current models. Anthropic's current line-up is the Claude 5 generation: public reports describe Claude Fable 5 (June 2026), Claude Opus 5 (July 2026) and Claude Opus 5.5 (September 2026). Confirm current names and limits on Anthropic's site.
Where it is strong
Scores are Halden’s editorial view of typical fit on a 0–5 scale. They are not benchmark results and will differ by task, model version and plan: test on your own work.
Coding, analytics, documents, research
Very strong for reading a whole codebase, planning a change and making careful edits, especially through Claude Code.
Good at reasoning about tables, contracts and reports, and at explaining its logic. Use it to draft the analysis, then verify key figures.
A standout for long documents, structured briefs, policy drafts and editing in a consistent voice.
Handles very long source material well; pair it with connectors or search to bring in current information.
Practical tips
What has changed recently
Coverage describes Opus 5.5 as the first of the Claude 5.5 line, with performance close to Fable 5.1 at a lower running cost.
Source: DiggReports say Opus 5 reached near-Fable-5 performance at roughly half the price.
Source: GigazineReports describe Fable 5 as bringing previously restricted high-end capability to the public.
Source: AI IndigoCompiled on October 9, 2026 from public reporting, much of it secondary. Dates, names and specifications can change, so confirm on Claude’s own site before you rely on them.
