Questions about alternatives to LFM3
What is the best open source alternative to LFM3?
1-bit Bonsai is listed first. PrismML's 1-bit LLMs that run on phones and laptops.
Is there a free alternative to LFM3?
Yes. The code of all 3 is public under Apache 2.0, so you can use them with no licence fee. Running one yourself costs the server and your time to look after it, and some makers also sell a hosted plan.
Which LFM3 alternatives can I host on my own server?
All 3: 1-bit Bonsai, Gemma 4 and Qwen3.5 Small. Each tool's page says what it needs to run.
What licences do they use?
Apache 2.0 (3). MIT, BSD and Apache let you change and reuse the code freely.
What do I lose by leaving LFM3?
The hosting. LFM3's maker runs the servers for you; with an open source tool the updates, backups, security fixes and support are yours, unless you take the maker's hosted plan. Features differ too, so check what each one imports and exports before you move your data.
