What is Ollama?

Ollama v0.40.11 adds local speech output on macOS, with an OpenAI-compatible audio endpoint.

Ollama v0.40.11 can generate speech on macOS: ollama run reads text or a model's reply aloud as it is produced, and apps can stream audio from an OpenAI-compatible /v1/audio/speech endpoint using the Phonon voice model. The same release adds d3, a family of 2B–27B decision models that classify, answer yes or no, or score options with probabilities. v0.40.10 added NVIDIA's Nemotron 3.5 Bolt E4B with a speculative-decoding draft.

What is Sourcegraph?

Sourcegraph stopped selling search to developers and started selling retrieval to their agents.

The product line has reorganized around coding agents as the customer. Code Finder runs its own search loop and hands an agent exact files and line ranges; Deep Search now executes scripts in a sandbox against the search APIs so a migration audit returns a CSV checklist rather than thousands of files of tokens; Agentic Batch Changes entered public beta to scope and ship migrations across hundreds of repositories. The argument threaded through all of it is that an agent searching on its own is slower, costlier, and worse than one handed scoped results.

Ollama v0.40.11 adds local speech output on macOS, with an OpenAI-compatible audio endpoint.

◆ Current state

Ollama v0.40.11 can generate speech on macOS: ollama run reads text or a model's reply aloud as it is produced, and apps can stream audio from an OpenAI-compatible /v1/audio/speech endpoint using the Phonon voice model. The same release adds d3, a family of 2B–27B decision models that classify, answer yes or no, or score options with probabilities. v0.40.10 added NVIDIA's Nemotron 3.5 Bolt E4B with a speculative-decoding draft.

◆ Where it's heading

Ollama is widening from a local text LLM runner into a local runtime for several model types: vision, decision scoring and now speech. The release candidates show the groundwork, with Phonon checkpoint support, a voice catalog and Gemma 4 draft heads landing over a few days before the stable cut.

◆ Prediction

Expect speech output to reach Linux and Windows and more voices in the Phonon catalog; the decision-model work (PPLX Decider, d3) suggests more classifier-style models.

Sourcegraph stopped selling search to developers and started selling retrieval to their agents.

◆ Current state

The product line has reorganized around coding agents as the customer. Code Finder runs its own search loop and hands an agent exact files and line ranges; Deep Search now executes scripts in a sandbox against the search APIs so a migration audit returns a CSV checklist rather than thousands of files of tokens; Agentic Batch Changes entered public beta to scope and ship migrations across hundreds of repositories. The argument threaded through all of it is that an agent searching on its own is slower, costlier, and worse than one handed scoped results.

◆ Where it's heading

Two consequences of that repositioning are already showing. First, Sourcegraph is pushing into other vendors' agents rather than waiting for its own surface — reranking Claude Code's file picker on symbols instead of path characters is integration work on someone else's tool. Second, scoped retrieval is being sold as governance: if you can prove which files an agent read before it shipped a change, agent context becomes an audit trail, which is the wedge into regulated engineering teams. The security posts extend the same logic from migrations to vulnerability remediation across ten thousand repositories.

◆ Prediction

Expect Agentic Batch Changes to move from public beta toward general availability, and more retrieval integrations into third-party coding agents. The provenance angle looks like the basis of an enterprise tier aimed at regulated buyers.
