OpenAI Weighs $500 ChatGPT Pro Max Plan With Faster Codex on Cerebras

OpenAI is preparing a premium $500-per-month ChatGPT Pro Max tier centered on a much faster Codex, powered by expanded Cerebras hardware for ultra-fast inference, according to BleepingComputer. The pitch is speed: Codex-Spark previously launched on Cerebras at over 1,000 tokens per second, and OpenAI demonstrated GPT-5.6 Sol running at up to 750 output tokens per second—throughput that transforms the experience of agentic coding, where latency compounds across many tool calls.

The hardware angle is strategically notable. By leaning on Cerebras's wafer-scale engines for inference rather than solely Nvidia GPUs, OpenAI diversifies its compute supply and unlocks speed profiles that are hard to achieve on conventional accelerators—a hedge in a market where GPU capacity is fiercely contested.

The $500 price point sits atop OpenAI's existing tiers and signals a bet that professional developers and enterprises will pay a steep premium for speed and priority access. It also aligns with a leaked always-on assistant 'O' (r/singularity, 301 upvotes) powered by an Astra variant 'Aeon' tuned for long-running tasks—suggesting OpenAI is segmenting toward power users willing to pay for continuous, fast agents.

The community reaction was skeptical: on developer threads, many questioned whether faster Codex justifies a 2.5x jump over the existing $200 Pro tier, particularly when DeepSeek V4.1-Flash offers frontier-adjacent coding at a fraction of the cost. The pricing also lands awkwardly amid OpenAI's frozen frontier training—selling a premium speed tier while pausing model development invites scrutiny. Whether Pro Max ships, and at what real-world speed, will test how much developers value latency over cost.
