Dosu vs Perplexity: at a glance
What is Dosu?
Dosu is folding agent session logs into the knowledge base it already maintains.
The August Drop turns old agent logs into Dosu knowledge, adds configuration from chat, and surfaces what the agents actually read. It follows Decant by a week — the local tool that parses Claude Code and Codex session logs into per-session cost and activity numbers — so the two releases sit on the same axis from opposite ends: Decant reads the logs on the developer's machine, Dosu now ingests them as a knowledge source. The monthly Drop format continues, with July's removing the waitlist and simplifying Knowledge Cache tools.
What is Perplexity?
Perplexity is selling access to other people's models, and now repricing them weekly.
The Gateway API put Anthropic, OpenAI, Google, xAI, and Perplexity models behind one endpoint reachable with an existing Perplexity key, and the MCP server became a remote service hosted by Perplexity with no local installation. Since then the traffic has been commercial rather than structural: GPT-5.6 price cuts, a Sol Fast mode, and successive preset re-pointings — low and fast both now run openai/gpt-5.6-luna, with the fast preset carrying priority processing at twice standard token prices. Frozen configurations have to be updated by hand each time.
Dosu vs Perplexity: editorial side-by-side
Dosu
6.3AI-ASSISTANTS
Dosu is folding agent session logs into the knowledge base it already maintains.
◆ Current state
The August Drop turns old agent logs into Dosu knowledge, adds configuration from chat, and surfaces what the agents actually read. It follows Decant by a week — the local tool that parses Claude Code and Codex session logs into per-session cost and activity numbers — so the two releases sit on the same axis from opposite ends: Decant reads the logs on the developer's machine, Dosu now ingests them as a knowledge source. The monthly Drop format continues, with July's removing the waitlist and simplifying Knowledge Cache tools.
◆ Where it's heading
Dosu started by maintaining repository knowledge and is now positioning agent output as an input to it. That closes a loop: agents read the docs Dosu maintains, and their sessions become material Dosu learns from. The Drops also show a steady flattening of setup friction — waitlist removed, libraries and agents overhauled, configuration moved into chat — which is the pattern of a product trying to shorten time-to-value rather than widen its feature surface.
◆ Prediction
Expect the log ingestion and Decant's cost data to converge into one view of what agents cost against the maintenance work Dosu absorbs, which the August Drop's impact reporting now partially supplies.
Perplexity
8.8AI-ASSISTANTS
Perplexity is selling access to other people's models, and now repricing them weekly.
◆ Current state
The Gateway API put Anthropic, OpenAI, Google, xAI, and Perplexity models behind one endpoint reachable with an existing Perplexity key, and the MCP server became a remote service hosted by Perplexity with no local installation. Since then the traffic has been commercial rather than structural: GPT-5.6 price cuts, a Sol Fast mode, and successive preset re-pointings — low and fast both now run openai/gpt-5.6-luna, with the fast preset carrying priority processing at twice standard token prices. Frozen configurations have to be updated by hand each time.
◆ Where it's heading
Perplexity is behaving like an infrastructure vendor rather than an answer engine: the differentiator is the credential and the routing, not the model. The preset churn is the visible cost of that position — when the models underneath are someone else's, keeping a named tier meaningful means re-pointing it whenever the market moves, and passing the migration work to customers who pinned a configuration. Inline citations across the search-backed presets remain the one capability that is distinctly Perplexity's own.
◆ Prediction
Expect the preset re-pointings to keep arriving at this cadence and the priority-processing tier to spread beyond the fast preset, since a 2x price band is easier to extend than to justify on one preset alone.
