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.

What is Deep Lake?

Deep Lake is rebuilding itself as a Postgres extension.

The visible release history is thin — three entries spanning a version 3 patch and two version 4 releases. The 4.x work splits between the core dataset format and pg_deeplake, a Postgres extension that has been gaining SQL type support, automatic table reload and library preloading. The 4.4.1 release added a storage directory listing API, mesh type support, PLY visualisation, a simple visualiser, and a 30% improvement in LRU cache insertion time.

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.

Deep Lake is rebuilding itself as a Postgres extension.

◆ Current state

The visible release history is thin — three entries spanning a version 3 patch and two version 4 releases. The 4.x work splits between the core dataset format and pg_deeplake, a Postgres extension that has been gaining SQL type support, automatic table reload and library preloading. The 4.4.1 release added a storage directory listing API, mesh type support, PLY visualisation, a simple visualiser, and a 30% improvement in LRU cache insertion time.

◆ Where it's heading

Two things stand out. The query engine was separated from the execution module and group-by execution was pulled out on its own, which is architecture work done ahead of features rather than after them. And the pg_deeplake investment points at meeting users inside the database they already query rather than asking them to adopt a separate dataset API. Version-locked read-only views fit the same picture — reproducible reads for teams treating datasets as versioned artefacts.

◆ Prediction

The query core separation and group-by refactor were both described as groundwork, so query execution features are the likely next visible step in pg_deeplake.
