By Anthropic
Model family: Claude
Claude Sonnet 4.5 is built to be the everyday workhorse in Anthropic’s lineup. It follows instructions cleanly, plans its steps on harder problems, and explains choices with steady logic, so you can trust it for complex analysis, math, and repository-scale coding without the latency of the heaviest tier. The model accepts images alongside text for document, chart, and screenshot understanding, then returns grounded, well-structured answers that hold up in production. It streams responses for conversational UX, calls tools and functions with precise arguments, and emits deterministic JSON when automations require strict schemas. Long-context handling keeps multi-document prompts coherent, retrieval grounding reduces hallucination, and alignment tuning maintains safe, controllable behavior. Teams adopt Sonnet 4.5 as their default engine—routing only the most demanding tasks to a larger model—because it balances accuracy, speed, and cost while fitting neatly into modern agent and RAG pipelines.

Overview
Claude Sonnet 4.5 is Anthropic’s balanced, production-ready model—faster than Opus while delivering strong reasoning, coding, and multimodal (text + image) skills. It supports long context, tool/function calling, and schema-true JSON, making it a dependable default for RAG copilots and agents.

The most humanly AI i have used so far but the problem is as soon as you start piling up messages in single chat session , it starts getting slow and at some point it starts freezing and also uses a lot of resources. For time being its okay to do 3 4 messages but as soon as we continue it has messages limitation and also starts getting very very slow . For the price of £18 per month this is unacceptable and with the newly introduced feature called project, if we start new chat within the project we cannot continue with the context we provided in other chats within same project. There are lot of improvements for them to work on. And to start with the its speed and its price

Cursor — v2Much stronger coding performance, with big benchmark gains over Composer 1.5 across CursorBench, Terminal-Bench 2.0, and SWE-bench Multilingual. Better long-horizon task solving, aimed at coding jobs that require hundreds of actions instead of shorter edit loops. Stronger base model training from Cursor’s first continued pretraining run, giving reinforcement learning a better foundation than before. Better price-to-intelligence balance, positioned as a much stronger model without giving up cost efficiency. Adds a faster same-intelligence variant and makes fast mode the default option.

Been really using Venice. UI is clean, I like the live counter while waiting for replies or images, it's small but useful. The replies come in fast without the usual filters you see elsewhere. It's more to the point, feels casual and doesn't waste your time. Good pick if you just want something straightforward without the privacy trade offs.
