GPT-5.6 just made itself better...

Tools shown in this video, with timestamps
OpenAI's top model, used with Codex to optimize its own serving: 20% lower serving costs from GPU kernel improvements and 15% better token generation from improved speculative decoding. It got no price cut, but the API fast mode is now 2.5x speed for 2x price.
Smallest of the three GPT-5.6 models, now 80% cheaper at $0.20/M input and $1.20/M output tokens. On Artificial Analysis it slightly beats GLM 5.2 max at about 6 cents per task versus roughly 26 cents.
Newly released Chinese open-source model near the frontier. It is half the price of GPT-5.6 Soul per token but uses about twice as many tokens per task, so the effective cost is similar.
Middle model of the GPT-5.6 family, received a 20% price cut to $2 per million input and $12 per million output tokens.
Open-source Chinese model used as a comparison point. It scores slightly below GPT-5.6 Luna max at roughly 26 cents per task.
Claude Opus 5 low scores slightly below Luna and GLM 5.2 but costs about 40 cents per task.
Sponsor platform for always-on agents, each with its own cloud environment, access to multiple providers' models, sub-agent delegation and a skill marketplace where the creator published his loopy skill. Included as a recommendation but is sponsor content.
Andrej Karpathy's open-source repo where a model runs a loop of its own experiments to improve training of a small LLM. It found improvements Karpathy himself had missed, and the creator compares OpenAI's self-optimization loop to it.
Anthropic's top model, shown at $2.75 per task on Artificial Analysis. The creator says Anthropic had it internally months before public release.
Shown on the cost-per-task chart at about 50 cents per task with similar intelligence to Luna.
Claude Sonnet 5 Max has about the same intelligence as GPT-5.6 Luna max but costs $1.80 per task versus 6 cents.
