What is ChatGPT?

OpenAI is turning Codex into the wedge — and DeployCo into the channel that lands it.

OpenAI's recent surface area centers on Codex. The last week brings customer stories from NVIDIA, AutoScout24, and finance teams; security tooling for running Codex safely; and adoption data showing Q1 growth concentrated in older users. Around the developer push, the firm just stood up DeployCo as an enterprise deployment arm and shipped GPT-5.5-Cyber under Trusted Access for verified cybersecurity work.

What is Perplexity?

Perplexity is selling access to other people's models, not just its own answers.

The recent changelog is almost entirely API-side. A Gateway API fronts open-weight models behind one endpoint that speaks both OpenAI Chat Completions and Anthropic Messages, a remote MCP server exposes Perplexity to outside agents, and the Agent API keeps absorbing new models. Consumer-facing notes — preset tuning, inline citations for research presets — read as maintenance beside that.

ChatGPT vs Perplexity: editorial side-by-side

OpenAI is turning Codex into the wedge — and DeployCo into the channel that lands it.

◆ Current state

OpenAI's recent surface area centers on Codex. The last week brings customer stories from NVIDIA, AutoScout24, and finance teams; security tooling for running Codex safely; and adoption data showing Q1 growth concentrated in older users. Around the developer push, the firm just stood up DeployCo as an enterprise deployment arm and shipped GPT-5.5-Cyber under Trusted Access for verified cybersecurity work.

◆ Where it's heading

Less new-model splash, more proving Codex is enterprise-ready: telemetry, sandboxing, named customers, and a dedicated deployment company to absorb integration work. Vertical models like GPT-5.5-Cyber suggest a willingness to fragment the lineup for high-trust use cases. Demand signals frame this as scaling out of an already-large base, not chasing a new audience.

◆ Prediction

Expect more named-customer Codex stories in regulated industries and a follow-on vertical model — finance or legal are the obvious candidates — paired with DeployCo case content that translates the deployment company into measurable revenue.

Perplexity is selling access to other people's models, not just its own answers.

◆ Current state

The recent changelog is almost entirely API-side. A Gateway API fronts open-weight models behind one endpoint that speaks both OpenAI Chat Completions and Anthropic Messages, a remote MCP server exposes Perplexity to outside agents, and the Agent API keeps absorbing new models. Consumer-facing notes — preset tuning, inline citations for research presets — read as maintenance beside that.

◆ Where it's heading

The product is splitting in two: an answer engine for end users and an inference-and-routing layer for developers. Price moves in the same window, a GPT-5.6 cut and a faster low-cost mode, put Perplexity in a cost-per-token argument rather than an answer-quality one. Building the gateway to mimic the two dominant API dialects makes the switching cost it removes its own.

◆ Prediction

Expect more hosted open-weight models behind the gateway and firmer pricing tiers, with the remote MCP server moving from a listed feature to a documented, permissioned surface.
