An independent developer has published a guide to AI image generation based on hands-on experiments calling several image-generation providers from Python, including ChatGPT and API-based models. The guide covers how diffusion models work, pricing differences across providers, and practical advice on prompting and building image generation into code and agents.
The Call Center Doctors rented a four-GPU Nvidia H200 server on September 27 to run DeepSeek V4.1 Flash for its Claude Code coding agents instead of Claude Opus 5.5. The firm found the on-demand box cost $440.88 a day versus $184-$223 a day to get the same work done through DeepSeek's API, and it ultimately switched back to Opus 5.5, which worked out cheaper than keeping the rented hardware running.
OpenAI paused new sign-ups for its $200 ChatGPT Pro tier on September 10 after heavy demand, leaving the $100 Pro plan as the top option for new buyers. OpenAI executive Thibault Sottiaux says sign-ups will reopen September 30 at the same $200 price, but with roughly half the previous API-dollar allowance and no five-hour usage cap. TestingCatalog has also spotted an unannounced $500/month 'Pro Max' tier appearing in the subscription interface.
OpenAI announced it will reopen its $200 Pro subscription to new subscribers, alongside a change to how usage is calculated that effectively halves the equivalent API spend compared to the previous version of the plan. The company says it will not reintroduce a prior 5-hour usage limit, and plans to add new subscription features, not yet detailed, that won't count against usage limits. OpenAI also noted it recently cut prices on its GPT-6 Sol and GPT-6 Luna models by 50%.
Artificial Analysis maintains an Intelligence Index that plots large language models against their blended API cost per million tokens, using a 3:1 input-to-output ratio and a log-price scale. The tool highlights a 'value frontier' of models that aren't beaten on both price and intelligence by any other option, showing only top variants and hiding low scorers by default, with filters to expand the view.
OpenAI has updated its smaller GPT-6 models, Sol and Luna, following this month's launch of the flagship GPT-6 Astra. The company says API access to the new Sol and Luna models costs half as much as the previous 5.6 series, citing gains in caching and inference, and claims GPT-6 Sol makes roughly half as many factual mistakes as its predecessor while also reducing coding errors.
