Rumors claim OpenAI is preparing to release GPT-5.6, GPT-5.6 Pro, and bidirectional voice model GPT-Bidi-1

It looks like we’re getting a whole range of new GPT models this Thursday:

GPT-5.6, 5.6 Pro, and a new bidirectional voice model.

Initial tests of the voice model were outstanding, this is exactly what I had hoped for two years ago!

@chetaslua we do not expect new checkpoints, kindle is the release checkpoint and is very unlikely to change at this stage

@Ananth7e It will get wilder if we anyhow get fable back

@chetaslua 5.6 Pro in Codex??

@chetaslua Polymarket disagrees

@chetaslua Lots of updates. Wild week

@chetaslua Sure i’m waiting

@chetaslua imagine if fable also returns this week

easily the week of the year

@synthwavedd @chetaslua This Thursday release?

@chetaslua Im gonna choose gpt and codex over Claude everyday

@chetaslua seriously there will be model named gpt-bidi-1 ?

@chetaslua will pro be in codex?

@0xwilt @chetaslua polymarket is not an oracle

@RealEverNever @chetaslua i feel confused with naming, because bidi also means cigarette 🥴🚬

@chetaslua add Sonnet 5 and gemini 3.5 pro to that list. although I don't think we'll get these

@chetaslua 5.6 pro is the last "special" model until context length breaks the economics.

GPT-Bidi-1 is the hedge against running out of smart engineers before we run out of compute

@chetaslua @grok 这是真的吗，为什么polymarket预测不会在30号之前发布

@Ananth7e @chetaslua @grok consider this last possibility. Likely or no

@RDuckyy Same 😁

@nisxant @chetaslua Bi-directional. OpenAI loves naming their models literal. GPT, imagen, omni..
