oMLX 0.7.4.dev1 dev build links two Macs: an M5 Max helps a high-memory Mac process long prompts, up to 2.9x faster at 64K tokens
oMLX 0.7.4.dev1 is out!
github.com/jundot/omlx/releases…
With the new Prefill Accelerator, connect an M5 Max to your big Mac and prefill up to 2.9x faster!
Prefill Accelerator (64K prompt, M3 Ultra 512GB + M5 Max 128GB)
- DeepSeek V4.1 Flash: 1,060 -> 3,123 tok/s (+195%)
- Qwen3.8 Flash-Next: 1,309 -> 3,666 tok/s (+180%)
- GLM-5.3 Flash: 540 -> 1,388 tok/s (+157%)
- MiniMax M3.1: 297 -> 569 tok/s (+92%)
- An M5 Max 64GB still adds 30-118%, and decode speed stays the same.
Faster DeepSeek V4.1 with A8 and buffer pool improvements
- Prefill on M5 Ultra is 43-48% faster, 32K goes 2,631 -> 3,779 tok/s (+44%).
- oQ4e builds now run INT8 Activation Prefill on M5.
Faster Qwen3.8 Flash-Next
- FP16 builds get the fused kernels. Decode on M3 Ultra goes 38.9 -> 63.0 tok/s (+62%), and +23% on M2 Max.
- Decode after long prompts is 3-5% faster on M5 Max.
Better for agents
- Parallel tool results from Claude Code reach the model in call order, so Qwen no longer pairs a result with the wrong call.
- Agent sessions on a cluster reuse the prompt cache across tool turns, 743 -> 9,266 cached tokens by the fifth turn.
- Switch oMLX models inside Codex and Copilot with /model.
Also in 0.7.4.dev1
- Ming-3.0 TTS with a 2x faster decode loop.
- Ask AI can use an oMLX server on another Mac.
- Check for model updates in the macOS app.
- German across the web dashboard and the macOS app.
- Batched decode with 6 requests on 8-bit models is 16% faster.
