Our take
Written Aug 2, 2026Inkling is a 952.4-billion-parameter downloadable model from Thinking Machines with a one-million-token request limit and broad multimodal input. Released in mid-2026 under a permissive Apache licence, it excels at coding and mathematics while its creative writing and agentic performance lag behind.
Choose this when you need a very large downloadable model under a permissive licence, or for long-document work at one million tokens. It suits coding tasks best — that is where its benchmark scores peak — and handles text, image and audio input with text output. Skip it if you need strong creative writing, reliable agentic behaviour, or consistent speed across providers.
The case for it
- 952.4 billion total parameters, the largest we have recorded under Apache License 2.0.
- Coding is its standout skill: 53.4 points above its general chat score on the same benchmark family.
- Strong mathematical reasoning at 1478.8964 on the Arena Maths benchmark.
- One-million-token request limit supports long documents and extended conversations.
The case against it
- Creative writing trails its other capabilities by 54.9 points below general chat and 108.3 below coding on the same benchmark family.
- Agentic performance is negative on the one measured task, scoring -0.0571.
- Throughput varies sharply by provider: the fastest measured is 2.4 times the slowest.

WritingWe do not rate this
Two boards come close and neither tests writing: Arena Creative Writing asks people which of two replies they prefer, and LiveBench Language tests whether a model understood a passage. So we show where Inkling placed and give it no mark out of five.
These tests check whether a model follows instructions — a precondition for all the work above, but not a measure of how well that work is done, which is why they get no rating.

GeForce RTX 4090 · 24 GB
Too large for this card. The weights do not fit even with part of them offloaded to system memory.
Apple M1 Pro (16-core GPU) · 32 GB
Too large for this card. The weights do not fit even with part of them offloaded to system memory.
Radeon RX 7900 XT · 20 GB
Too large for this card. The weights do not fit even with part of them offloaded to system memory.
Memory use by level
Against a 24 GB card.
All 3 sizes here are calculated, not measured. We hold no measured file for this model, so each size comes from the parameter count and every verdict above inherits that uncertainty.

What each host's API supports
From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.

What we do not know about this model yet
- We hold no measured file for it, so all 3 sizes on this page are calculated from the parameter count.
- 1 of 5 listings publish no parameter list, so what their API accepts is unknown to us.
- Nothing we hold says whether an endpoint streams, so we do not show it either way.
- 2 of 5 listings do not say whether they train on prompts.
