Mercury 3 is live: the most capable diffusion LLM released to date.
It outperforms GPT-6 Luna and Claude Haiku 5.5 across a range of benchmarks while running at over 1,000 tokens per second.
More than 40x the size of Mercury 1, 3x more intelligent across standard benchmarks, and just as fast, with a 1M-token context window.
Available today on the Inception API, @baseten, and @OpenRouter .

Mark Peng from @Tiny_Fish in an interview with @_inception_ai's Emily Liu: “We’ve been running the latest Mercury 3 diffusion model through our most mature evaluation harness at TinyFish for the web agent and the results have been quite impressive.
In terms of task completion and success, it performs on par or better with Sonnet 5.5 from Anthropic and it clearly outperforms GPT Sol, and it does so at less than a tenth of the cost.”
Glad to partner with @_inception_ai for the Mercury 3 launch!
Impressive results in TinyFish’s web agent evaluations: frontier-level performance at less than a tenth of the cost. Looking forward to more collaborations ahead.

Yesterday, we launched Mercury 3, our fastest model to date with speeds over 1000+ tokens/second on @nvidia hardware.
In this demo from @stefan_webb, we compare Mercury 3 + @opencode against Claude Code with Sonnet 5.5 and other model/harness combinations on a coding task utilizing many subagents running in parallel. (🧵1/2)

Mercury 3 excels in tasks where a combination of strong intelligence and speed is necessary - in this example it is an order of magnitude faster and cheaper than competing models.

A clarification: “Intelligence Index” refers here to a weighted average of the following benchmarks: GDPval, SciCode, Tau3-Banking, AA-Omniscience-Public, IFBench, SO Quality, AA-LCR v1.1, GPQA Diamond, AA-Omniscience-Public (Non-Hallucination), Terminal-Bench v2.1, BrowseComp+, and DeepSearchQA (DSQA)
@ 30.
This is not the same as Artificial Analysis’s Intelligence Index.
We have renamed Intelligence Index to Model Quality, GDPval AA v2 to GDPval, and AA-Omniscience to AA-Omniscience-Public in our announcement blog post to avoid confusion.

Mercury 2 has been named one of @TIME's Best Inventions of 2026!
Our first reasoning diffusion LLM, and the first of its kind in production, was recognized in the AI category.
Thank you to the judges for recognizing diffusion LLMs as one of the technologies shaping the future of AI. The lower latencies offered by diffusion LLMs opens the door for real-time AI systems like coding models, voice agents, and search engines.
It’s a great win for diffusion LLMs. More to come! 🧵

👁️ Mercury Decide now accepts image input, which opens it up to a much wider range of applications:
openrouter.ai/inception/merc…
In the demo from @stefan_webb, Mercury Decide plays Ring King on NES, using Mercury Decide’s new vision capabilities to understand the state of the game and suggest the next action to take.
What about the other applications? (🧵 1/4)

Mercury Decide with vision performs strongly on vision benchmarks, leading CV-Bench outright and beating the current 2nd place, Imajev-4B, on the public set of Image JevBench.
How do you get started? (🧵3/4)

Mercury Decide from @_inception_ai now accepts image input on OpenRouter
Put images alongside text in the state of a Decisions request, and Mercury Decide answers your typed questions from what's in the image: a choice, a score, or a yes/no with a probability attached
Pricing is unchanged: free endpoint, or $0.02/M input with zero data retention. Images bill as input tokens

Congrats to the @_inception_ai team on launching Mercury Decide, the highest-accuracy decision model at the lowest cost!
Try it from the Baseten Model Library: baseten.co/library/mercury-d…
One week ago we launched Mercury Decide, @_inception_ai System One decision model. It hit #2 on OpenRouter by users, and we've been improving it every day since.
Independent results from @ValsAI show that Mercury Decide is more accurate and more affordable than Jev.
Proud of how fast this team moves.
Free on @OpenRouter and available through the Inception API and @baseten. I'd love to see what you build.

🌏 Availability: Mercury Decide is now available via Inception, OpenRouter, and Baseten with Zero Data Retention (ZDR). And we’re keeping the free-tier on OpenRouter!
🏷️ Pricing via Inception, OpenRouter, and Baseten with ZDR is lower than Jev at $0.02/$0 per 1M in/out on OpenRouter with ZDR, with an initial 50% discount from the list price $0.04/$0 plus 100M free tokens.
So how do you get started? [🧵3/4]
