What is Gamma?
Gamma is doubling down on being the AI-native presentation surface — for humans and for agents.
Gamma has spent six months reinforcing two lanes in parallel. The AI lane: Nano Banana Pro / HD for image generation, smarter Claude and ChatGPT connectors, AI animations as a generative media source. The editor lane: six-column layouts, gradient cards, syntax-highlighted code blocks, adaptive-theme logos. The Generate API going GA in November opened a programmatic surface that the recent connector improvements now build on.
What is Spectra?
Spectra shipped a brand-new block plugin and a paid tier for it on the same afternoon.
Spectra launched Spectra Blocks, a ground-up Gutenberg block plugin, on 13 July 2026, with Spectra Blocks Pro arriving ninety seconds later in the same changelog. The month since has been a tight 1.0.x cadence: version rollback, automatic theme colour sync, and fixes across both the free and Pro builds. Two releases landed on 7 August alone, one for each edition.
Gamma vs Spectra: editorial side-by-side
Gamma
6.3DESIGN
Gamma is doubling down on being the AI-native presentation surface — for humans and for agents.
◆ Current state
Gamma has spent six months reinforcing two lanes in parallel. The AI lane: Nano Banana Pro / HD for image generation, smarter Claude and ChatGPT connectors, AI animations as a generative media source. The editor lane: six-column layouts, gradient cards, syntax-highlighted code blocks, adaptive-theme logos. The Generate API going GA in November opened a programmatic surface that the recent connector improvements now build on.
◆ Where it's heading
The product is splitting into two related surfaces — a human-facing editor that keeps gaining visual polish, and an AI/agent-facing layer where presentations get generated and modified through chat connectors or API calls. The May connector update plus the earlier API GA point at a deliberate move to be the default deck-generation backend for agentic workflows, not just a destination tool that users open in a browser.
◆ Prediction
Expect tighter agent loops next: deck editing as a callable tool inside Claude and ChatGPT (not just one-shot generation), and a paid programmatic tier targeted at agent-builders shipping deck-export features.
Spectra
6.3DESIGN
Spectra shipped a brand-new block plugin and a paid tier for it on the same afternoon.
◆ Current state
Spectra launched Spectra Blocks, a ground-up Gutenberg block plugin, on 13 July 2026, with Spectra Blocks Pro arriving ninety seconds later in the same changelog. The month since has been a tight 1.0.x cadence: version rollback, automatic theme colour sync, and fixes across both the free and Pro builds. Two releases landed on 7 August alone, one for each edition.
◆ Where it's heading
This is an early-life product being hardened in public, and the choices reveal the audience. Version rollback is a safety net for agencies who update client sites and need an exit; theme colour sync is about blocks inheriting the site palette instead of fighting it. Both point at Spectra Blocks being positioned as infrastructure a professional builds on rather than a set of decorative blocks.
◆ Prediction
Expect the 1.0.x fix cadence to continue for several more weeks before the block library itself starts expanding, with Pro staying a release or two behind the free edition. The changelog bodies are truncated in this feed, so which specific blocks ship next is not visible from here.
