“Build a dataset of the major AI coding agents and coding models launched or significantly updated in 2026 so far. Include company, product, announcement date, what changed, pricing, context window where relevant, and a source for every row.”
A curated dataset of major AI coding launches and substantial updates from 1 January to 1 September 2026: 18 coding agents and tools and 29 coding-capable models across 15 companies, each row tied to a cited source. Activity accelerates sharply from May, peaking at 13 releases in each of July and August.
| Date | Category | Company | Product | What changed | Pricing | Context window | Source |

Curated dataset of 47 major 2026 AI coding releases (18 agents/tools, 29 coding-capable models) through 2026-09-01, assembled from a scan of official product, news and blog pages plus a few release indexes and changelogs; it is not mathematically exhaustive. “Major” means a new named coding agent/tool, a major agent release, or a model with material coding or agentic-software-engineering capability; small patches and routine integrations were excluded. Pricing is launch-time or source-stated availability, not necessarily today's price; context window shown only when the source states it; blanks stay blank. Some dates reflect page publication or update dates rather than explicit launch days. One Meta row (Muse Spark 1.2) carries no date and is listed at the end of the table and omitted from the timeline.
