What just dropped: Inception released Mercury 3 yesterday. It's a "diffusion" AI model, a different kind of AI than ChatGPT or Claude, and it writes over 1,000 tokens per second. The simple version (how it's different): Most AI models (ChatGPT, Claude, Gemini) write like a typewriter: one word at a time, left to right. Mercury works more like an AI image generator. It sketches a rough version of the whole answer at once, then sharpens it in a few passes until it's clean. That's why it's so fast. Why this one matters: A lot of people doubted this approach could ever get smart enough to compete. Mercury 3 is over 40x bigger than Mercury 1, and Inception says it matches or beats GPT-6 Luna and Claude Haiku 5.5 (the fast, cheap versions of the big models) while running 4-8x faster. Quick specs: - Speed: 1,068 tokens per second - Memory: 1 million tokens of context (you can paste in a LOT of documents) - Price: $0.20 per million input tokens, $0.70 per million output tokens - Launch deal: 50% off right now ($0.10 / $0.35). They haven't said when the discount ends. The free part (read before you sign up): - New accounts on the Inception API platform get 100 million free tokens. No credit card needed to start. - It's a one-time credit, not monthly, and it's shared across all their models. - When it runs out, you add a card to keep going. - The free tier has per-minute rate limits, which is plenty for testing. - The free tokens are for the API. The chat site is a separate way to try it. The honest part: - The benchmark wins and quotes come from Inception and its early partners. Test it on your own tasks before you switch anything. - Inception compares it to the fast, cheap tier of models. For your hardest reasoning work, your top model is probably still the better pick. Where it shines: Anything where waiting ruins the experience: voice agents, support bots, tutoring apps, and browser agents that take lots of steps. Small delays add up fast when an agent makes dozens of calls.
