Confirmed facts
GPT-5.4 Thinking is presented by OpenAI as its strongest reasoning model in ChatGPT.[29]
GPT-5.4 mini is available in ChatGPT, including for lighter-access tiers via the “Thinking” feature, according to OpenAI’s March 18, 2026 release note.[7]
OpenAI’s official ChatGPT plan docs currently show GPT-5.3, GPT-5.4, and GPT-5.2 variants in use.[9]
OpenAI’s API docs currently show specialized model families for image generation, realtime speech, and text-to-speech.[1]
GPT-4.1 was officially introduced as an API family including GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano.[17]
OpenAI officially introduced o3 and o4-mini as reasoning models with tool use.[18]
What remains inference
The “new OpenAI models in 2026” most likely means the GPT-5.3 / GPT-5.4 generation, especially GPT-5.4 and GPT-5.4 mini, because those are the clearly current names on official 2026 ChatGPT pages.[7][9][29]
If you mean only models first launched during calendar year 2026, Insufficient evidence to give a complete launch-only list from the snippets alone, because several official pages show current availability or retirement rather than original announcement dates.[9][21][25][29]
What the evidence suggests
For ChatGPT users in 2026, the main current high-end models appear to be GPT-5.4 Thinking and GPT-5.4 Pro, with GPT-5.3 Instant as the faster general-use option and GPT-5.4 mini as a lighter model.[7][9][29]
For API users, OpenAI appears to be maintaining a broader catalog than ChatGPT, including specialized image, realtime, and voice models, and keeping some ChatGPT-retired models available in the API.[1][25][26]
Conflicting evidence or uncertainty
I did not find one single official “2026 model roundup” page; the answer has to be pieced together from official model notes, plan-limit pages, and retirement notices.[7][9][21][25][29]
I also found official pages for “open models” and “gpt-oss,” but the search snippets did not give enough date context for me to confidently include them as confirmed “new 2026” models in this answer.[30][33]
Open questions
Do you want the ChatGPT model lineup, the API model lineup, or only models first launched in 2026?
Do you want a simple “best model for coding, writing, research, image, and voice” recommendation list?
Sources worth trusting most
OpenAI API docs, because they are first-party documentation for currently supported API models.[1]
OpenAI Help Center model and plan pages, because they describe current ChatGPT availability, retirements, and limits, and some are updated within days.[7][9][25][29]
OpenAI’s own product announcement pages for GPT-4.1 and o3/o4-mini, because they confirm those model families and their intended use cases.[17][18]
Recommended next step
I can turn this into a very short cheat sheet like: “best OpenAI model in 2026 for chat, coding, research, speed, cheapest API, image, and voice.” If you want, I’ll make it simple.
Summary
The strongest official evidence points to GPT-5.3, GPT-5.4, and GPT-5.4 mini as OpenAI’s clearly current ChatGPT-era models in 2026, with GPT-5.2 variants also still documented in plan pages.[7][9][29] Older ChatGPT models such as GPT-5.1, GPT-5, GPT-4o, GPT-4.1, and o4-mini have been retired from ChatGPT, while the API still shows a broader set of available and specialized models.[1][21][25][26]

What's next The release of OpenAI o3‑mini marks another step in OpenAI’s mission to push the boundaries of cost-effective intelligence. By optimizing reasoning for STEM domains while keeping costs low, we’re making high-quality AI even more accessible. This model continues our track record of driving down the cost of intelligence—reducing per-token pricing by 95% since launching GPT‑4—while maintaining top-tier reasoning capabilities. As AI adoption expands, we remain committed to leading at the frontier, building models that balance intelligence, efficiency, and safety at scale. ## Author…

Key findings

OpenAI also says GPT-5, GPT-4o, GPT-4.1, GPT-4.1 mini, and o4-mini were retired from ChatGPT on February 13, 2026.[21][25][26]
Confirmed facts
GPT-5.4 Thinking is presented by OpenAI as its strongest reasoning model in ChatGPT.[29]
GPT-5.4 mini is available in ChatGPT, including for lighter-access tiers via the “Thinking” feature, according to OpenAI’s March 18, 2026 release note.[7]
OpenAI’s official ChatGPT plan docs currently show GPT-5.3, GPT-5.4, and GPT-5.2 variants in use.[9]
OpenAI’s API docs currently show specialized model families for image generation, realtime speech, and text-to-speech.[1]
GPT-4.1 was officially introduced as an API family including GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano.[17]
OpenAI officially introduced o3 and o4-mini as reasoning models with tool use.[18]
What remains inference
The “new OpenAI models in 2026” most likely means the GPT-5.3 / GPT-5.4 generation, especially GPT-5.4 and GPT-5.4 mini, because those are the clearly current names on official 2026 ChatGPT pages.[7][9][29]
If you mean only models first launched during calendar year 2026, Insufficient evidence to give a complete launch-only list from the snippets alone, because several official pages show current availability or retirement rather than original announcement dates.[9][21][25][29]
What the evidence suggests
For ChatGPT users in 2026, the main current high-end models appear to be GPT-5.4 Thinking and GPT-5.4 Pro, with GPT-5.3 Instant as the faster general-use option and GPT-5.4 mini as a lighter model.[7][9][29]
For API users, OpenAI appears to be maintaining a broader catalog than ChatGPT, including specialized image, realtime, and voice models, and keeping some ChatGPT-retired models available in the API.[1][25][26]
Conflicting evidence or uncertainty
I did not find one single official “2026 model roundup” page; the answer has to be pieced together from official model notes, plan-limit pages, and retirement notices.[7][9][21][25][29]
I also found official pages for “open models” and “gpt-oss,” but the search snippets did not give enough date context for me to confidently include them as confirmed “new 2026” models in this answer.[30][33]
Open questions
Do you want the ChatGPT model lineup, the API model lineup, or only models first launched in 2026?
Do you want a simple “best model for coding, writing, research, image, and voice” recommendation list?
Sources worth trusting most
OpenAI API docs, because they are first-party documentation for currently supported API models.[1]
OpenAI Help Center model and plan pages, because they describe current ChatGPT availability, retirements, and limits, and some are updated within days.[7][9][25][29]
OpenAI’s own product announcement pages for GPT-4.1 and o3/o4-mini, because they confirm those model families and their intended use cases.[17][18]
Recommended next step
I can turn this into a very short cheat sheet like: “best OpenAI model in 2026 for chat, coding, research, speed, cheapest API, image, and voice.” If you want, I’ll make it simple.
Summary
The strongest official evidence points to GPT-5.3, GPT-5.4, and GPT-5.4 mini as OpenAI’s clearly current ChatGPT-era models in 2026, with GPT-5.2 variants also still documented in plan pages.[7][9][29] Older ChatGPT models such as GPT-5.1, GPT-5, GPT-4o, GPT-4.1, and o4-mini have been retired from ChatGPT, while the API still shows a broader set of available and specialized models.[1][21][25][26]

What's next The release of OpenAI o3‑mini marks another step in OpenAI’s mission to push the boundaries of cost-effective intelligence. By optimizing reasoning for STEM domains while keeping costs low, we’re making high-quality AI even more accessible. This model continues our track record of driving down the cost of intelligence—reducing per-token pricing by 95% since launching GPT‑4—while maintaining top-tier reasoning capabilities. As AI adoption expands, we remain committed to leading at the frontier, building models that balance intelligence, efficiency, and safety at scale. ## Author…
