xAI / Grok 4.6
proDescription
xAI's newest flagship, built for agents for longer tasks. Grok 4.6 is a post-training upgrade over 4.5, tuned to sustain multi-step work without drifting and to verify its own results more often before proceeding. It reads text and images, searches both the web and X, and its knowledge is among the most recent in the catalog. Same context window as the previous generation, with a new top reasoning level for the hardest work.
OpenAI / GPT-5 Nano
lightDescription
OpenAI's smallest and cheapest GPT-5 model, built for speed above all. GPT-5 Nano is made for summarisation, classification, and other well-defined tasks that run at high volume. It reads text and images, with adjustable reasoning effort. Reasoning depth is shallow by design and its knowledge is dated. The trade is cost: it is among the cheapest models in the catalog.

xAI / Grok 4.6
proLong-Running Coding Agents
xAI tuned it for agents that stay on a coding task across many steps without losing the thread, with reported gains in agentic and terminal coding. Built to turn a broad idea into a working prototype in fewer iterations.
Effort Up To Xhigh
Reasoning effort runs low, medium, high, and a new xhigh level above the previous generation's ceiling, for the hardest problems. xAI reports it self-tests and verifies its own work more often before proceeding.
Room For Large Repositories
A large context window, unchanged from the previous generation. Handles large repositories, long research packets, and extended agent histories, though requests above a high threshold are billed at a higher rate.
Knowledge Work Artifacts
xAI positions it for research, information analysis, and complex work artifacts alongside coding. Suited to long documents and structured output that has to survive review, not just read well.
Web Search And X Search
xAI states Grok knows nothing beyond its training data, and provides server-side Web Search and X Search tools. Its knowledge is recent, and X Search reaches posts no other model can read.
Text And Image Input
xAI accepts text and image inputs in JPG or PNG format, in any order, alongside your prompt, with text output. Send screenshots, diagrams, or scanned pages. Audio and video are not listed as supported inputs.
OpenAI / GPT-5 Nano
lightCoding Sub-Tasks
Suited to small, well-scoped coding jobs and to acting as a fast sub-agent inside a larger system, rather than tackling whole problems. Reasoning depth is limited, so keep the scope tight.
Adjustable Reasoning Effort
Reasoning effort runs from minimal through low, medium, and high. Even at higher effort it is a shallow reasoner by design, so it suits speed-sensitive work rather than hard multi-step problems.
Room For Long Documents
A large context window, enough to summarise long reports or classify big batches of text in a single pass without splitting the input into separate requests.
Summarisation And Classification
OpenAI names summarisation and classification as its core uses. Built to process high volumes of text quickly and cheaply rather than to produce polished long-form writing.
Analysis On Older Knowledge
Its training data is dated by current standards, so it is fine for processing text you supply but weaker on recent events, which need live sources rather than the model's own knowledge.
Text And Image Input
Reads text and images, so you can send screenshots or scanned pages alongside your prompt. Output is text only. OpenAI states audio and video are not supported.
