Grok Build
xAI's terminal-native coding agent. The Grok Build CLI runs up to eight parallel sub-agents through a plan-first loop, is MCP-compatible, and is powered by grok-build-0.1 (70.8% on SWE-Bench Verified, 256K context). In beta for SuperGrok and X Premium+ subscribers; the model is also on the API at $0.20/$1.50 per million tokens.

Our take
Grok Build is xAI's entry in the terminal coding-agent race - a CLI running up to eight parallel sub-agents with a plan-first loop and MCP support, scoring 70.8% on SWE-Bench Verified. It's still in beta and gated behind SuperGrok or X Premium+, though the model is on the API at competitive rates. The field is crowded (Claude Code, Codex, Gemini CLI), but parallel sub-agents make it worth testing.
Best for
Developers in the xAI/X ecosystem who want a terminal coding agent that parallelises work across multiple sub-agents.
Pros
- Runs up to eight parallel sub-agents from the terminal
- Plan-first loop with MCP compatibility
- Solid 70.8% on SWE-Bench Verified
- Underlying model also on the API at competitive rates
Cons
- Still in beta - not for critical workflows yet
- Gated behind SuperGrok / X Premium+ subscriptions
- Crowded field (Claude Code, Codex, Gemini CLI)
How it compares
Against Claude Code and Gemini CLI in our catalog, Grok Build's pitch is eight parallel sub-agents and tie-in with xAI's Grok models.
Full review
Grok Build is xAI's terminal-native coding agent, shipped in May 2026. The CLI runs a plan-first loop and can fan work out across up to eight parallel sub-agents, with MCP compatibility so it can call external tools. It is powered by grok-build-0.1, which scores 70.8% on SWE-Bench Verified with a 256,000-token context window - a credible, independently styled benchmark rather than a vendor claim.
Access is the catch: it is in beta, available to SuperGrok and X Premium+ subscribers (with a promotional SuperHeavy tier), while the model itself is on the API at $0.20 per million input and $1.50 per million output tokens. Being beta, it is best for side projects and non-critical tasks rather than a daily driver. The terminal coding-agent space is crowded, but the parallel sub-agent design and tie-in to xAI's models make it worth a look for developers already in that ecosystem.

Composio
Composio provides the execution infrastructure that connects AI agents to real software. It sits at the tooling and connectivity layer of the agent stack, giving developers one framework - SDKs, a CLI and 850+ pre-built connectors - to let agents act across apps such as GitHub, Slack and Salesforce. It handles the hard parts: complex authentication and OAuth, plus remote sandboxed environments for safe execution, exposed over the Model Context Protocol so agents can reason and then reliably take action. The platform is built for production, with SOC 2 and ISO 27001:2022 certifications and deployment across public cloud, VPC and on-premises. Composio operates from San Francisco and Bangalore and raised a $25M Series A led by Lightspeed, with angels including Vercel's Guillermo Rauch and HubSpot's Dharmesh Shah.
LiteLLM
LiteLLM, from BerriAI, is an open-source AI gateway that gives you a single OpenAI-compatible interface to 140+ providers and 2,500+ models, including OpenAI, Anthropic, Gemini, Bedrock, Azure, Mistral, Ollama and vLLM. You can use it as a lightweight Python SDK for direct calls, or deploy the proxy server as a centralized gateway for a team, with virtual keys, budgets, load balancing, rate limiting, request logging and LLM guardrails. It has become a default building block in the AI stack, with 45,000+ GitHub stars, 240M+ Docker pulls and over a billion requests served, and is used by companies including Netflix, Adobe and Stripe. The core is free; an enterprise tier adds JWT auth, SSO/SAML, audit logs, SLAs and dedicated support.
