Create PPT on public modelsagi
create a ppt about all the models openai has released publicly since the start of the year
Worked for 13m 9s
I created a 7-slide, source-backed deck covering the public OpenAI model releases from January 1, 2026 through April 16, 2026. It includes an explicit counting rule, a master release table, grouped launch slides for the main model waves, and a closing exclusions slide so the scope is defensible.
I rendered local previews before export and wrote the final editable .pptx to the output folder.

FEBRUARY04 / 07
Coding Led the Year Off
OpenAI started 2026 by widening Codex in two directions: higher-end autonomy and near-instant collaboration.
GPT-5.3-Codex
Introduced on Feb. 5 as an agentic coding model, combining coding with broader professional knowledge.
GPT-5.3-Codex-Spark
Launched on Feb. 12 as a smaller research-preview model for real-time coding, with initial public access through ChatGPT Pro Codex surfaces.
Why it mattered
The releases opened up two coding lanes: long-running, high-capability agentic work and low-latency interactive edits.

MARCH 3–505 / 07
Then the Frontier Line Reset
Early March introduced a new everyday ChatGPT model and then a unified frontier family above it.
GPT-5.3 Instant
OpenAI rolled out GPT-5.3 Instant on March 3 with more accurate answers, smoother tone, and better web-grounded results for everyday ChatGPT use.
GPT-5.4
On March 5, GPT-5.4 became the new unified frontier model, bringing together reasoning, coding, agentic workflows, and professional document work.
GPT-5.4 Pro
OpenAI paired GPT-5.4 with a professional model for sophisticated, higher-ceiling work in ChatGPT and the API.
All meaningful copy and layout objects are editable in PowerPoint. Source URLs live in speaker notes.

MARCH–APRIL06 / 07
The Small-Model Ladder Expanded Fast
After GPT-5.4 landed, OpenAI quickly added cheaper and fallback variants to extend coverage across workloads and plans.
GPT-5.4 mini
Released on March 17 across the API, Codex, and ChatGPT, bringing much of GPT-5.4’s capability to faster and cheaper coding and subagent workloads.
GPT-5.4 nano
Launched the same day as the smallest and cheapest GPT-5.4 variant, aimed at classification, extraction, ranking, and simple coding-support tasks.
GPT-5.3 Instant Mini
Added on April 16 as a ChatGPT fallback after GPT-5.3 Instant limits. It does not appear in the master pricing tier.
All meaningful copy and layout objects are editable in PowerPoint. Source URLs live in speaker notes.

BOUNDARIES07 / 07
What Counted, What Did Not
The boundary between a public release, a retune, and a limited-access variant is the main judgment call in this deck.
Counted
Newly introduced model SKUs publicly announced by OpenAI between January 1 and April 16, 2026, with a public release or official model listing.
Not Counted
GPT-5.2 retunes and GPT-5.3 Instant updates were retunes, not new SKUs. Limited-access variants are excluded.
Takeaway
The first quarter began with frontier models, wider coding coverage, and cheaper options across Codex and ChatGPT.
All meaningful copy and layout objects are editable in PowerPoint. Source URLs live in speaker notes.
