Grok 5 (Upcoming)

Status

Expected: Q2-Q3 2026 (slipped from original Q1 2026 target) Polymarket: ~33% chance by June 30, 2026 Training: Active on Colossus 2 (MACROHARD)

> ⚠️ Slipped timeline: Musk originally targeted Q1 2026, then Q2. As of mid-June 2026, no release. Likely Q3 for full API access.

What We Know

Parameters

• 6 trillion (MoE – only subset activates per query)
• xAI training a 10 trillion model in parallel (separate variant)^{[xai-10t-model-nextbigfuture.md]}

Architecture

• Mixture-of-Experts (MoE) – roughly double Grok 4's estimated 3T
• Multi-agent system: expected expansion from 4 agents (Grok 4.20) to 16+ agents
• Native multimodal: text, images, audio, real-time video, temporal reasoning
• Context window: reported 1.5M tokens

Training Infrastructure

• Colossus 2: 550,000+ NVIDIA GB200/GB300 GPUs
• 400+ MW power, ~$18B hardware cost alone
• 7 models in training simultaneously (as of Apr 2026)^{[xai-10t-model-nextbigfuture.md]}:

- 2× 1T variants, 2× 1.5T variants, 6T, 10T, Imagine V2
