Kimi K3.1 Pro vs Gemini 2.5 Flash-Lite Overview
Everything you need to know about these AI models, including capabilities, performance, pricing, and technical details.
Kimi / Kimi K3.1 Pro
proDescription
Moonshot AI's newest flagship and the first model in its K3.1 series, built as a post-trained upgrade to Kimi K3. Moonshot reports Terminal-Bench 4.0 results just behind Claude Opus 5.5, a top OfficeQA Pro v2 score, and far fewer factual errors than K3. It reads text and images across a very large context and reasons before answering. Moonshot is releasing open weights.
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.

Why Use Kimi K3.1 Pro and Gemini 2.5 Flash-Lite?
Aymo gives you more than access to individual models—it provides a complete multi-model AI workspace designed for productivity.
Kimi / Kimi K3.1 Pro
proClose To Opus 5.5
Moonshot reports 65.7% on Terminal-Bench 4.0, just behind Claude Opus 5.5 at 66.4% and ahead of GPT-6 Astra at 58.2%. These are Moonshot's own results.
Reasoning Built In
Reasons through each request before it replies. Moonshot reports 61.2% on its long-horizon coding test, up from 55.95% for Kimi K3, after much larger post-training.
Room For Long Inputs
A very large context window of about 1 million tokens, according to Moonshot. Load a full repository, long filings, or a research set in one request.
Finance And Office Work
Moonshot reports a top score of 64.4 on OfficeQA Pro v2, and a rise in Financial Research from 58.8 to 70.4 over Kimi K3 on its internal tests.
Fewer Factual Errors
On Moonshot's hardest accuracy test, claim-level errors fell from 23.4% with Kimi K3 to 8.3%. It has no native web search, so current data comes through connected tools.
Text And Image Input
Reads text and images on Aymo. Moonshot also built it for 3D work from sketches and reference images, scoring 72.8 on BenchCAD without tools, level with Claude Opus 5.5.
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.
