Perplexity vs ragnar: at a glance
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.
What is ragnar?
ragnar turned its RAG store into an MCP server, so coding agents can search it directly.
ragnar builds retrieval-augmented generation stores in R on DuckDB, handling document chunking, embedding, and hybrid vector plus BM25 retrieval, and registering itself as a tool for ellmer chats. Version 0.3.0 adds mcp_serve_store(), which exposes a store over MCP to local clients such as Codex CLI and Claude Code, alongside Azure AI Foundry and Snowflake Cortex embedding providers. Store version 2, introduced in 0.2.0, brought chunk deoverlapping on retrieval and automatic heading augmentation.

◆ 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.
ragnar
0.0AI-ASSISTANTS
ragnar turned its RAG store into an MCP server, so coding agents can search it directly.
◆ Current state
ragnar builds retrieval-augmented generation stores in R on DuckDB, handling document chunking, embedding, and hybrid vector plus BM25 retrieval, and registering itself as a tool for ellmer chats. Version 0.3.0 adds mcp_serve_store(), which exposes a store over MCP to local clients such as Codex CLI and Claude Code, alongside Azure AI Foundry and Snowflake Cortex embedding providers. Store version 2, introduced in 0.2.0, brought chunk deoverlapping on retrieval and automatic heading augmentation.
◆ Where it's heading
The package keeps widening who can reach a store and how many ways they can query it. Retrieval accepts vectors of queries, the ellmer tool withholds chunks it has already returned so an agent can dig deeper across calls, and now the store is reachable from outside R entirely. Embedding providers are added steadily — LM Studio, then Azure and Snowflake — which keeps the store portable across whoever supplies the vectors. Breaking changes are accepted readily at this stage, including a renamed default tool prefix and a flipped default in ragnar_find_links().
◆ Prediction
More MCP surface is the natural next step now that serving exists, since the retrieval tool already has the multi-query and no-repeat behavior that agent-driven search depends on.
