Claude Sonnet 5.5 vs Gemini 2.5 Flash-Lite Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Anthropic / Claude Sonnet 5.5
proDescription
Anthropic's Sonnet model in the Claude 5.5 family, built for fast, well-scoped everyday work. Sonnet 5.5 improves on Sonnet 5 across coding, writing, and knowledge work, and often finishes the same task in fewer steps. It reads text, images, and PDFs, holds a very large context, and reasons with adjustable effort. Anthropic highlights its clearer writing and its sharp eye for design.
Google / Gemini 2.5 Flash-Lite
proDescription
Google's most cost-efficient and fastest model in the 2.5 family, built for high volume rather than hard problems. Despite the budget position, it reads text, images, video, and audio across a million-token context, and can ground answers in live search. Reasoning is optional, toggled through a thinking budget. Suited to classification, translation, and document processing at scale, where speed and cost decide.

Anthropic / Claude Sonnet 5.5
proFast Everyday Coding
Anthropic reports its biggest gains over Sonnet 5 in coding, with strong results on real-world agentic coding tests. Early testers note how fast it understands a codebase and batches tool calls into fewer steps.
Effort You Can Adjust
Reasoning effort runs from low to max, defaulting to medium in Anthropic's apps. Anthropic reports that its lower settings already beat Sonnet 5's best results on several tests, for far less work per task.
Room For Whole Projects
A very large context window, shared with the rest of the Claude 5.5 family. Load a full codebase or a long document set and work across it in one conversation without splitting it up.
Polished Documents And Slides
Anthropic highlights clearer writing and a sharp eye for design. It creates documents, slides, and spreadsheets that need little editing, and it can follow a slide template closely.
Professional Knowledge Work
Anthropic reports results close to Opus-level on tests of real-world work across many occupations, including long-horizon research. It has no native web search, so current data comes through connected tools.
Text And Image Input
Anthropic lists text and image input for all current Claude models, and Sonnet 5.5 reads screenshots, charts, and PDFs. Output is text only. Audio and video are not supported.
Google / Gemini 2.5 Flash-Lite
proCoding Assistance At Scale
Google lists coding assistance among its core uses. Built for high-frequency, repetitive coding help across many requests rather than deep single-problem work, where its speed and low cost pay off.
Optional Thinking Budget
Reasoning is off by default and can be switched on through a controllable thinking budget. Google reports the thinking mode meaningfully improves maths and code accuracy when a task warrants the extra time.
Million-Token Context
A one-million-token input window, the same as Google's flagship tier. Feed it entire books, long PDFs, or large codebases in a single request without chunking the input into separate calls.
High-Volume Text Processing
Google names translation, classification, document processing, and content moderation as its strengths. Built to run the same operation across large volumes of text reliably rather than to write long-form prose.
Search Grounding Built In
Supports Grounding with Google Search, code execution, and URL context as built-in tools, so it can pull current information into an answer. Useful when accuracy depends on live sources.
Text Image Video Audio
Accepts text, images, video, and audio input, with text output. An unusually broad input range for the cheapest model in the family, and rare in handling both video and audio at this price.
