Yes. With 512GB of unified memory, Mac Studio M5 Ultra 512GB fits 223 current LocalClaw catalogue models under the conservative 8k-context memory filter. Start with DeepSeek V4 Flash Vision Exp. Apple lists it for pre-order, with availability beginning September 22, 2026. This is memory-fit guidance, not a hands-on speed benchmark.
Hardware facts come from Apple. LocalClaw separately calculates catalogue compatibility from unified memory and model requirements. No unreleased Mac performance result is inferred from chip specifications.
Yes. With 512GB of unified memory, Mac Studio M5 Ultra 512GB fits 223 current LocalClaw catalogue models under the conservative 8k-context memory filter. Start with DeepSeek V4 Flash Vision Exp.

This configuration has 512GB of unified memory. Apple lists up to 512GB for the M5 Ultra family represented here. LocalClaw reserves memory for macOS, the runtime and an 8k context before marking a model compatible.
It is available to pre-order from Apple. Apple says availability begins September 22, 2026.
No. The compatibility count and ranking are calculated from 512GB of unified memory and the current LocalClaw catalogue. They are not measured tokens-per-second results or hands-on benchmarks.
Start with DeepSeek V4 Flash Vision Exp on this Mac. This Mac is not shipping yet, so LocalClaw has not hands-on validated runtime speed. Model fit is calculated conservatively from Apple-confirmed unified memory. A tight fit can still work, but close other apps, reduce context length when needed, and prefer the listed quantization.
Official MIT DeepSeek V4 Flash multimodal experiment with image understanding, 1M context and Unsloth Dynamic GGUF artifacts. The lightest practical GGUF is roughly 82-97GB, while higher-quality Q4/Q8 builds are about 155-162GB, so this belongs on large-memory workstations.
Official MIT DeepSeek V4 Flash successor release with stronger agentic coding, DSpark speculative decoding support and a practical Unsloth Dynamic GGUF path. Still a large workstation/server local model: Q4 is about 155GB and Q8 is about 162GB.
Official MIT 35B MoE reasoning model from Ornith AI with about 3B active parameters, 262K context, strong agentic-coding positioning and official Q4_K_M GGUF plus MLX/Ollama/llama.cpp local paths for larger workstations.
Meta Superintelligence Lab local agent model with text+image input, 131K context, Apache 2.0 weights and official GGUF/ExecuTorch artifacts. The K-Quant 17GB build targets 24GB machines; 32GB is safer for vision and long-context sessions.
Official Qwen dense 27B vision-language release with Apache 2.0 weights, 262K native context, thinking controls and strong agentic coding benchmarks. Practical local path through Unsloth and LM Studio-compatible GGUF artifacts.
IBM Granite 4.2 30B brings the permissive Apache 2.0 Granite stack to workstation-class local reasoning, RAG, coding and tool-use workflows with GGUF and MLX community artifacts.
InclusionAI's MIT-licensed instruct MoE optimized for fast agent workloads. 104B total parameters, only 7.4B active, hybrid linear attention, 262K context and strong tool-use / multi-step execution with high token efficiency.
IBM Granite 4.2 8B instruct model with Apache 2.0 weights, 128K context, thinking-mode chat template, tool calling and practical GGUF plus MLX paths for everyday local machines.
Z.ai flagship open model for long-horizon coding, reasoning and agentic work. 744B total, 40B active, 1M-token context, MIT license. Unsloth Dynamic GGUF makes it technically local, but it needs workstation/server-class memory: ~245GB total memory for 2-bit and 372GB+ for 4-bit.
The shared LocalClaw engine first rejects hosted-only, excluded and oversized records. It reserves system and 8k-context headroom, labels comfortable, good and tight fits, then ranks the remaining models by hardware fit, use case, catalogue capability ratings, runtime and freshness. Community stars are never included. This is practical guidance, not a standardized third-party benchmark.
This guide is about local AI fit, not live pricing. Prices and availability change. This Mac can be pre-ordered from Apple and is scheduled to become available September 22, 2026.
