Anthropic / Claude Haiku 5.5
proDescription
Anthropic's small, fast model in the Claude 5.5 family, built for high-volume, latency-sensitive work. Haiku 5.5 is a large step up from Haiku 4.5 on reasoning, knowledge work, and computer use, and it is the first Haiku with adjustable effort. It reads text, images, and PDFs and holds a very large context. Suited to summaries, extraction, quick answers, and sub-agent tasks.
xAI / Grok Build 0.1
proDescription
xAI's coding model, purpose-built for autonomous software engineering rather than chat. Grok Build 0.1 acts as an engineering agent: it reasons through a problem, writes code, runs your terminal, checks for errors, and fixes its own mistakes in a loop. It reads text and images, always reasons before answering, and natively supports Model Context Protocol. Built for long-horizon coding that runs with little supervision, at a low cost, tuned for agent loops.

Anthropic / Claude Haiku 5.5
proQuick Coding Tasks
Handles small fixes, code explanations, and sub-agent coding work alongside larger models. Anthropic recommends Sonnet or Opus for complex agentic coding, where Haiku 5.5 trails its bigger siblings.
First Haiku With Effort
The first Haiku model with an adjustable effort setting, defaulting to medium. Lower settings keep it fast and cheap, while higher ones let it think longer on harder questions.
Room For Long Inputs
A very large context window, shared with the rest of the Claude 5.5 family. Long documents, transcripts, and chat histories stay in view, which suits document question answering at volume.
Summaries And Extraction
Anthropic positions it for summaries, classification, extraction, and routing. Suited to fast, consistent structured output at high volume, rather than the most polished long-form writing.
Fast Knowledge Work
Anthropic reports a large jump over Haiku 4.5 on tests of real-world professional work. 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 Haiku 5.5 reads screenshots, charts, and PDFs. Output is text only. Audio and video are not supported.
xAI / Grok Build 0.1
proAutonomous Engineering Agent
Purpose-built to act as an engineering agent, not a code generator. Refactors across a codebase, invokes tools, runs tests, and iterates through multi-step development tasks, picking up your project conventions as it works.
Reasoning Always On
Every response includes structured reasoning before the final output, and effort is not configurable. Built for deliberate, multi-step work rather than instant answers, so it plans before it acts.
Repository-Scale Context
A large context window, roughly 190,000 words, is sufficient to hold a substantial codebase or a long agent history in a single session. Reporting notes no fixed output cap, so it can refactor large files in one go.
Structured Code Output
Supports structured outputs and a JSON schema, so it slots into agent pipelines and developer tooling. Built to produce parseable, tool-ready output rather than long-form prose.
Native MCP And Tool Use
Natively supports Model Context Protocol, so internal knowledge bases, proprietary APIs, and MCP servers plug in directly. Built to work inside existing developer tooling rather than a closed ecosystem.
Text And Image Input
xAI lists text and image input, with text output. Send source code, diagrams, UI mockups, or error screenshots in the same request. Audio and video are not supported.
