Best Tinker (Thinking Machines Lab) alternatives in 2026 (free and paid)
Tinker is built for people writing their own training code, and that is the main reason to look elsewhere. It is aimed at researchers, so it is not for no-code users. Billing is usage-based per million tokens, checkpoint storage costs $0.10 per GB-month, some models retire on set dates, and access starts with sign-up. The per-token rates could not be verified because the pricing table and docs pages did not load.
Claude is Anthropic's assistant for writing, analysis and coding; Pro is $20 per user per month and there is a free tier. Google Gemini has Google AI Plus at $4.99 per user per month with 2x the usage limits of Free and 400 GB of cloud storage, plus a free tier. Both are products for using models rather than fine-tuning open ones, so they replace Tinker only if your goal is the output, not a custom model.
If you do need LoRA fine-tuning of open models, neither of these covers it in our data.
